Adding unit tests for new features or test cases for bugs you've fixed helps us ensure that the Pull Request (PR) is acceptable.\n\nThere are many ways to contribute to Scrapling. Here are some of them:\n\n- Report bugs and request features using the [GitHub issues](https://github.com/D4Vinci/Scrapling/issues). Please follow the issue template to help us resolve your issue quickly.\n- Blog about Scrapling. Tell the world how youโ€™re using Scrapling. This will help newcomers with more examples and increase the Scrapling project's visibility.\n- Join the [Discord community](https://discord.gg/EMgGbDceNQ) and share your ideas on how to improve Scrapling. Weโ€™re always open to suggestions.\n- If you are not a developer, perhaps you would like to help with translating the [documentation](https://github.com/D4Vinci/Scrapling/tree/docs)?\n\n## Making a Pull Request\nTo ensure that your PR gets accepted, please make sure that your PR is based on the latest changes from the dev branch and that it satisfies the following requirements:\n\n- **The PR must be made against the [**dev**](https://github.com/D4Vinci/Scrapling/tree/dev) branch of Scrapling. Any PR made against the main branch will be rejected.**\n- **The code should be passing all available tests. We use tox with GitHub's CI to run the current tests on all supported Python versions for every code-related commit.**\n- **The code should be passing all code quality checks like `mypy` and `pyright`. We are using GitHub's CI to enforce code style checks as well.**\n- **Make your changes, keep the code clean with an explanation of any part that might be vague, and remember to create a separate virtual environment for this project.**\n- If you are adding a new feature, please add tests for it.\n- If you are fixing a bug, please add code with the PR that reproduces the bug.\n- Please follow the rules and coding style rules we explain below.\n\n\n## Finding work\n\nIf you have decided to make a contribution to Scrapling, but you do not know what to contribute, here are some ways to find pending work:\n\n- Check out the [contribution](https://github.com/D4Vinci/Scrapling/contribute) GitHub page, which lists open issues tagged as `good first issue`. These issues provide a good starting point.\n- There are also the [help wanted](https://github.com/D4Vinci/Scrapling/issues?q=is%3Aissue%20label%3A%22help%20wanted%22%20state%3Aopen) issues, but know that some may require familiarity with the Scrapling code base first. You can also target any other issue, provided it is not tagged as `invalid`, `wontfix`, or similar tags.\n- If you enjoy writing automated tests, you can work on increasing our test coverage. Currently, the test coverage is around 90โ€“92%.\n- Join the [Discord community](https://discord.gg/EMgGbDceNQ) and ask questions in the `#help` channel.\n\n## Coding style\nPlease follow these coding conventions as we do when writing code for Scrapling:\n- We use [pre-commit](https://pre-commit.com/) to automatically address simple code issues before every commit, so please install it and run `pre-commit install` to set it up. This will install hooks to run [ruff](https://docs.astral.sh/ruff/), [bandit](https://github.com/PyCQA/bandit), and [vermin](https://github.com/netromdk/vermin) on every commit. We are currently using a workflow to automatically run these tools on every PR, so if your code doesn't pass these checks, the PR will be rejected.\n- We use type hints for better code clarity and [pyright](https://github.com/microsoft/pyright)/[mypy](https://github.com/python/mypy) for static type checking. If your code isn't acceptable by those tools, your PR won't pass the code quality rule.\n- We use the conventional commit messages format as [here](https://gist.github.com/qoomon/5dfcdf8eec66a051ecd85625518cfd13#types), so for example, we use the following prefixes for commit messages:\n \n | Prefix | When to use it |\n |-------------|--------------------------|\n | `feat:` | New feature added |\n | `fix:` | Bug fix |\n | `docs:` | Documentation change/add |\n | `test:` | Tests |\n | `refactor:` | Code refactoring |\n | `chore:` | Maintenance tasks |\n \n Then include the details of the change in the commit message body/description.\n\n Example:\n ```\n feat: add `adaptive` for similar elements\n \n - Added find_similar() method\n - Implemented pattern matching\n - Added tests and documentation\n ```\n\n> Please donโ€™t put your name in the code you contribute; git provides enough metadata to identify the author of the code.\n\n## Development\n\n### Getting started\n\n1. Fork the repository and clone your fork:\n ```bash\n git clone https://github.com//Scrapling.git\n cd Scrapling\n git checkout dev\n ```\n\n2. Create a virtual environment and install dependencies:\n ```bash\n python -m venv .venv\n source .venv/bin/activate # On Windows: .venv\\Scripts\\activate\n pip install -e \".[all]\"\n pip install -r tests/requirements.txt\n ```\n\n3. Install browser dependencies:\n ```bash\n scrapling install\n ```\n\n4. Set up pre-commit hooks:\n ```bash\n pip install pre-commit\n pre-commit install\n ```\n\n### Tips\n\nSetting the scrapling logging level to `debug` makes it easier to know what's happening in the background.\n```python\nimport logging\nlogging.getLogger(\"scrapling\").setLevel(logging.DEBUG)\n```\nBonus: You can install the beta of the upcoming update from the dev branch as follows\n```commandline\npip3 install git+https://github.com/D4Vinci/Scrapling.git@dev\n```\n\n## Tests\nScrapling includes a comprehensive test suite that can be executed with pytest. However, first, you need to install all libraries and `pytest-plugins` listed in `tests/requirements.txt`. Then, running the tests will result in an output like this:\n ```bash\n $ pytest tests -n auto\n =============================== test session starts ===============================\n platform darwin -- Python 3.13.8, pytest-8.4.2, pluggy-1.6.0 -- /Users//.venv/bin/python3.13\n cachedir: .pytest_cache\n rootdir: /Users//scrapling\n configfile: pytest.ini\n plugins: asyncio-1.2.0, anyio-4.11.0, xdist-3.8.0, httpbin-2.1.0, cov-7.0.0\n asyncio: mode=Mode.STRICT, asyncio_default_fixture_loop_scope=function, asyncio_default_test_loop_scope=function\n 10 workers [515 items]\n scheduling tests via LoadScheduling\n\n ......\n\n =============================== 271 passed in 52.68s ==============================\n ```\nHere, `-n auto` runs tests in parallel across multiple processes to increase speed.\n\n**Note:** You may need to run browser tests sequentially (`DynamicFetcher`/`StealthyFetcher`) to avoid conflicts. To run non-browser tests in parallel and browser tests separately:\n```bash\n# Non-browser tests (parallel)\npytest tests/ -k \"not (DynamicFetcher or StealthyFetcher)\" -n auto\n\n# Browser tests (sequential)\npytest tests/ -k \"DynamicFetcher or StealthyFetcher\"\n```\n\nBonus: You can also see the test coverage with the `pytest` plugin below\n```bash\npytest --cov=scrapling tests/\n```\n\n## Building Documentation\nDocumentation is built using [Zensical](https://zensical.org/). You can build it locally using the following commands:\n```bash\npip install zensical\npip install -r docs/requirements.txt\nzensical build --clean # Build the static site\nzensical serve # Local preview\n```\n" }, { "path": "Dockerfile", "content": "FROM python:3.12-slim-trixie\n\nLABEL io.modelcontextprotocol.server.name=\"io.github.D4Vinci/Scrapling\"\nCOPY --from=ghcr.io/astral-sh/uv:latest /uv /uvx /bin/\n\n# Set environment variables\nENV DEBIAN_FRONTEND=noninteractive \\\n PYTHONUNBUFFERED=1 \\\n PYTHONDONTWRITEBYTECODE=1\n\nWORKDIR /app\n\n# Copy dependency file first for better layer caching\nCOPY pyproject.toml ./\n\n# Install dependencies only\nRUN --mount=type=cache,target=/root/.cache/uv \\\n uv sync --no-install-project --all-extras --compile-bytecode\n\n# Copy source code\nCOPY . .\n\n# Install browsers and project in one optimized layer\nRUN --mount=type=cache,target=/root/.cache/uv \\\n --mount=type=cache,target=/var/cache/apt \\\n --mount=type=cache,target=/var/lib/apt \\\n apt-get update && \\\n uv run playwright install-deps chromium && \\\n uv run playwright install chromium && \\\n uv sync --all-extras --compile-bytecode && \\\n apt-get clean && \\\n rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*\n\n# Expose port for MCP server HTTP transport\nEXPOSE 8000\n\n# Set entrypoint to run scrapling\nENTRYPOINT [\"uv\", \"run\", \"scrapling\"]\n\n# Default command (can be overridden)\nCMD [\"--help\"]" }, { "path": "LICENSE", "content": "BSD 3-Clause License\n\nCopyright (c) 2024, Karim shoair\n\nRedistribution and use in source and binary forms, with or without\nmodification, are permitted provided that the following conditions are met:\n\n1.

\n\nScrapling is an adaptive Web Scraping framework that handles everything from a single request to a full-scale crawl.\n\nIts parser learns from website changes and automatically relocates your elements when pages update. Its fetchers bypass anti-bot systems like Cloudflare Turnstile out of the box. And its spider framework lets you scale up to concurrent, multi-session crawls with pause/resume and automatic proxy rotation โ€” all in a few lines of Python. One library, zero compromises.\n\nBlazing fast crawls with real-time stats and streaming. Built by Web Scrapers for Web Scrapers and regular users, there's something for everyone.\n\n```python\nfrom scrapling.fetchers import Fetcher, AsyncFetcher, StealthyFetcher, DynamicFetcher\nStealthyFetcher.adaptive = True\np = StealthyFetcher.fetch('https://example.com', headless=True, network_idle=True) # Fetch website under the radar!\nproducts = p.css('.product', auto_save=True) # Scrape data that survives website design changes!\nproducts = p.css('.product', adaptive=True) # Later, if the website structure changes, pass `adaptive=True` to find them!\n```\nOr scale up to full crawls\n```python\nfrom scrapling.spiders import Spider, Response\n\nclass MySpider(Spider):\n name = \"demo\"\n start_urls = [\"https://example.com/\"]\n\n async def parse(self, response: Response):\n for item in response.css('.product'):\n yield {\"title\": item.css('h2::text').get()}\n\nMySpider().start()\n```\n\n

The entire codebase is automatically scanned with **PyRight** and **MyPy** with each change.\n- ๐Ÿ”‹ **Ready Docker image**: With each release, a Docker image containing all browsers is automatically built and pushed.\n\n## Getting Started\n\nLet's give you a quick glimpse of what Scrapling can do without deep diving.\n\n### Basic Usage\nHTTP requests with session support\n```python\nfrom scrapling.fetchers import Fetcher, FetcherSession\n\nwith FetcherSession(impersonate='chrome') as session: # Use latest version of Chrome's TLS fingerprint\n page = session.get('https://quotes.toscrape.com/', stealthy_headers=True)\n quotes = page.css('.quote .text::text').getall()\n\n# Or use one-off requests\npage = Fetcher.get('https://quotes.toscrape.com/')\nquotes = page.css('.quote .text::text').getall()\n```\nAdvanced stealth mode\n```python\nfrom scrapling.fetchers import StealthyFetcher, StealthySession\n\nwith StealthySession(headless=True, solve_cloudflare=True) as session: # Keep the browser open until you finish\n page = session.fetch('https://nopecha.com/demo/cloudflare', google_search=False)\n data = page.css('#padded_content a').getall()\n\n# Or use one-off request style, it opens the browser for this request, then closes it after finishing\npage = StealthyFetcher.fetch('https://nopecha.com/demo/cloudflare')\ndata = page.css('#padded_content a').getall()\n```\nFull browser automation\n```python\nfrom scrapling.fetchers import DynamicFetcher, DynamicSession\n\nwith DynamicSession(headless=True, disable_resources=False, network_idle=True) as session: # Keep the browser open until you finish\n page = session.fetch('https://quotes.toscrape.com/', load_dom=False)\n data = page.xpath('//span[@class=\"text\"]/text()').getall() # XPath selector if you prefer it\n\n# Or use one-off request style, it opens the browser for this request, then closes it after finishing\npage = DynamicFetcher.fetch('https://quotes.toscrape.com/')\ndata = page.css('.quote .text::text').getall()\n```\n\n### Spiders\nBuild full crawlers with concurrent requests, multiple session types, and pause/resume:\n```python\nfrom scrapling.spiders import Spider, Request, Response\n\nclass QuotesSpider(Spider):\n name = \"quotes\"\n start_urls = [\"https://quotes.toscrape.com/\"]\n concurrent_requests = 10\n \n async def parse(self, response: Response):\n for quote in response.css('.quote'):\n yield {\n \"text\": quote.css('.text::text').get(),\n \"author\": quote.css('.author::text').get(),\n }\n \n next_page = response.css('.next a')\n if next_page:\n yield response.follow(next_page[0].attrib['href'])\n\nresult = QuotesSpider().start()\nprint(f\"Scraped {len(result.items)} quotes\")\nresult.items.to_json(\"quotes.json\")\n```\nUse multiple session types in a single spider:\n```python\nfrom scrapling.spiders import Spider, Request, Response\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession\n\nclass MultiSessionSpider(Spider):\n name = \"multi\"\n start_urls = [\"https://example.com/\"]\n \n def configure_sessions(self, manager):\n manager.add(\"fast\", FetcherSession(impersonate=\"chrome\"))\n manager.add(\"stealth\", AsyncStealthySession(headless=True), lazy=True)\n \n async def parse(self, response: Response):\n for link in response.css('a::attr(href)').getall():\n # Route protected pages through the stealth session\n if \"protected\" in link:\n yield Request(link, sid=\"stealth\")\n else:\n yield Request(link, sid=\"fast\", callback=self.parse) # explicit callback\n```\nPause and resume long crawls with checkpoints by running the spider like this:\n```python\nQuotesSpider(crawldir=\"./crawl_data\").start()\n```\nPress Ctrl+C to pause gracefully โ€” progress is saved automatically. Later, when you start the spider again, pass the same `crawldir`, and it will resume from where it stopped.\n\n### Advanced Parsing & Navigation\n```python\nfrom scrapling.fetchers import Fetcher\n\n# Rich element selection and navigation\npage = Fetcher.get('https://quotes.toscrape.com/')\n\n# Get quotes with multiple selection methods\nquotes = page.css('.quote') # CSS selector\nquotes = page.xpath('//div[@class=\"quote\"]') # XPath\nquotes = page.find_all('div', {'class': 'quote'}) # BeautifulSoup-style\n# Same as\nquotes = page.find_all('div', class_='quote')\nquotes = page.find_all(['div'], class_='quote')\nquotes = page.find_all(class_='quote') # and so on...\n# Find element by text content\nquotes = page.find_by_text('quote', tag='div')\n\n# Advanced navigation\nquote_text = page.css('.quote')[0].css('.text::text').get()\nquote_text = page.css('.quote').css('.text::text').getall() # Chained selectors\nfirst_quote = page.css('.quote')[0]\nauthor = first_quote.next_sibling.css('.author::text')\nparent_container = first_quote.parent\n\n# Element relationships and similarity\nsimilar_elements = first_quote.find_similar()\nbelow_elements = first_quote.below_elements()\n```\nYou can use the parser right away if you don't want to fetch websites like below:\n```python\nfrom scrapling.parser import Selector\n\npage = Selector(\"...\")\n```\nAnd it works precisely the same way!\n\n### Async Session Management Examples\n```python\nimport asyncio\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession, AsyncDynamicSession\n\nasync with FetcherSession(http3=True) as session: # `FetcherSession` is context-aware and can work in both sync/async patterns\n page1 = session.get('https://quotes.toscrape.com/')\n page2 = session.get('https://quotes.toscrape.com/', impersonate='firefox135')\n\n# Async session usage\nasync with AsyncStealthySession(max_pages=2) as session:\n tasks = []\n urls = ['https://example.com/page1', 'https://example.com/page2']\n \n for url in urls:\n task = session.fetch(url)\n tasks.append(task)\n \n print(session.get_pool_stats()) # Optional - The status of the browser tabs pool (busy/free/error)\n results = await asyncio.gather(*tasks)\n print(session.get_pool_stats())\n```\n\n## CLI & Interactive Shell\n\nScrapling includes a powerful command-line interface:\n\n[![asciicast](https://asciinema.org/a/736339.svg)](https://asciinema.org/a/736339)\n\nLaunch the interactive Web Scraping shell\n```bash\nscrapling shell\n```\nExtract pages to a file directly without programming (Extracts the content inside the `body` tag by default). If the output file ends with `.txt`, then the text content of the target will be extracted. If it ends in `.md`, it will be a Markdown representation of the HTML content; if it ends in `.html`, it will be the HTML content itself.\n```bash\nscrapling extract get 'https://example.com' content.md\nscrapling extract get 'https://example.com' content.txt --css-selector '#fromSkipToProducts' --impersonate 'chrome' # All elements matching the CSS selector '#fromSkipToProducts'\nscrapling extract fetch 'https://example.com' content.md --css-selector '#fromSkipToProducts' --no-headless\nscrapling extract stealthy-fetch 'https://nopecha.com/demo/cloudflare' captchas.html --css-selector '#padded_content a' --solve-cloudflare\n```\n\n> [!NOTE]\n> There are many additional features, but we want to keep this page concise, including the MCP server and the interactive Web Scraping Shell. Check out the full documentation [here](https://scrapling.readthedocs.io/en/latest/)\n\n## Performance Benchmarks\n\nScrapling isn't just powerfulโ€”it's also blazing fast. The following benchmarks compare Scrapling's parser with the latest versions of other popular libraries.\n\n### Text Extraction Speed Test (5000 nested elements)\n\n| # | Library | Time (ms) | vs Scrapling | \n|---|:-----------------:|:---------:|:------------:|\n| 1 | Scrapling | 2.02 | 1.0x |\n| 2 | Parsel/Scrapy | 2.04 | 1.01 |\n| 3 | Raw Lxml | 2.54 | 1.257 |\n| 4 | PyQuery | 24.17 | ~12x |\n| 5 | Selectolax | 82.63 | ~41x |\n| 6 | MechanicalSoup | 1549.71 | ~767.1x |\n| 7 | BS4 with Lxml | 1584.31 | ~784.3x |\n| 8 | BS4 with html5lib | 3391.91 | ~1679.1x |\n\n\n### Element Similarity & Text Search Performance\n\nScrapling's adaptive element finding capabilities significantly outperform alternatives:\n\n| Library | Time (ms) | vs Scrapling |\n|-------------|:---------:|:------------:|\n| Scrapling | 2.39 | 1.0x |\n| AutoScraper | 12.45 | 5.209x |\n\n\n> All benchmarks represent averages of 100+ runs. See [benchmarks.py](https://github.com/D4Vinci/Scrapling/blob/main/benchmarks.py) for methodology.\n\n## Installation\n\nScrapling requires Python 3.10 or higher:\n\n```bash\npip install scrapling\n```\n\nThis installation only includes the parser engine and its dependencies, without any fetchers or commandline dependencies.\n\n### Optional Dependencies\n\n1. If you are going to use any of the extra features below, the fetchers, or their classes, you will need to install fetchers' dependencies and their browser dependencies as follows:\n ```bash\n pip install \"scrapling[fetchers]\"\n \n scrapling install # normal install\n scrapling install --force # force reinstall\n ```\n\n This downloads all browsers, along with their system dependencies and fingerprint manipulation dependencies.\n\n Or you can install them from the code instead of running a command like this:\n ```python\n from scrapling.cli import install\n \n install([], standalone_mode=False) # normal install\n install([\"--force\"], standalone_mode=False) # force reinstall\n ```\n\n2. Extra features:\n - Install the MCP server feature:\n ```bash\n pip install \"scrapling[ai]\"\n ```\n - Install shell features (Web Scraping shell and the `extract` command): \n ```bash\n pip install \"scrapling[shell]\"\n ```\n - Install everything: \n ```bash\n pip install \"scrapling[all]\"\n ```\n Remember that you need to install the browser dependencies with `scrapling install` after any of these extras (if you didn't already)\n\n### Docker\nYou can also install a Docker image with all extras and browsers with the following command from DockerHub:\n```bash\ndocker pull pyd4vinci/scrapling\n```\nOr download it from the GitHub registry:\n```bash\ndocker pull ghcr.io/d4vinci/scrapling:latest\n```\nThis image is automatically built and pushed using GitHub Actions and the repository's main branch.\n\n## Contributing\n\nWe welcome contributions!

Use when asked to scrape, crawl, or extract data from websites; web_fetch fails; the site has anti-bot protections; write Python code to scrape/crawl; or write spiders.\nversion: 0.4.2\nlicense: Complete terms in LICENSE.txt\n---\n\n# Scrapling\n\nScrapling is an adaptive Web Scraping framework that handles everything from a single request to a full-scale crawl.\n\nIts parser learns from website changes and automatically relocates your elements when pages update. Its fetchers bypass anti-bot systems like Cloudflare Turnstile out of the box. And its spider framework lets you scale up to concurrent, multi-session crawls with pause/resume and automatic proxy rotation โ€” all in a few lines of Python. One library, zero compromises.\n\nBlazing fast crawls with real-time stats and streaming. Built by Web Scrapers for Web Scrapers and regular users, there's something for everyone.\n\n**Requires: Python 3.10+**\n\n**This is the official skill for the scrapling library by the library author.**\n\n\n## Setup (once)\n\nCreate a virtual Python environment through any way available, like `venv`, then inside the environment do:\n\n`pip install \"scrapling[all]>=0.4.2\"`\n\nThen do this to download all the browsers' dependencies:\n\n```bash\nscrapling install --force\n```\n\nMake note of the `scrapling` binary path and use it instead of `scrapling` from now on with all commands (if `scrapling` is not on `$PATH`).\n\n### Docker\nAnother option if the user doesn't have Python or doesn't want to use it is to use the Docker image, but this can be used only in the commands, so no writing Python code for scrapling this way:\n\n```bash\ndocker pull pyd4vinci/scrapling\n```\nor\n```bash\ndocker pull ghcr.io/d4vinci/scrapling:latest\n```\n\n## CLI Usage\n\nThe `scrapling extract` command group lets you download and extract content from websites directly without writing any code.\n\n```bash\nUsage: scrapling extract [OPTIONS] COMMAND [ARGS]...\n\nCommands:\n get Perform a GET request and save the content to a file.\n post Perform a POST request and save the content to a file.\n put Perform a PUT request and save the content to a file.\n delete Perform a DELETE request and save the content to a file.\n fetch Use a browser to fetch content with browser automation and flexible options.\n stealthy-fetch Use a stealthy browser to fetch content with advanced stealth features.\n```\n\n### Usage pattern\n- Choose your output format by changing the file extension. Here are some examples for the `scrapling extract get` command:\n - Convert the HTML content to Markdown, then save it to the file (great for documentation): `scrapling extract get \"https://blog.example.com\" article.md`\n - Save the HTML content as it is to the file: `scrapling extract get \"https://example.com\" page.html`\n - Save a clean version of the text content of the webpage to the file: `scrapling extract get \"https://example.com\" content.txt`\n- Output to a temp file, read it back, then clean up.\n- All commands can use CSS selectors to extract specific parts of the page through `--css-selector` or `-s`.\n\nWhich command to use generally:\n- Use **`get`** with simple websites, blogs, or news articles.\n- Use **`fetch`** with modern web apps, or sites with dynamic content.\n- Use **`stealthy-fetch`** with protected sites, Cloudflare, or anti-bot systems.\n\n> When unsure, start with `get`. If it fails or returns empty content, escalate to `fetch`, then `stealthy-fetch`. The speed of `fetch` and `stealthy-fetch` is nearly the same, so you are not sacrificing anything.\n\n#### Key options (requests)\n\nThose options are shared between the 4 HTTP request commands:\n\n| Option | Input type | Description |\n|:-------------------------------------------|:----------:|:-----------------------------------------------------------------------------------------------------------------------------------------------|\n| -H, --headers | TEXT | HTTP headers in format \"Key: Value\" (can be used multiple times) |\n| --cookies | TEXT | Cookies string in format \"name1=value1; name2=value2\" |\n| --timeout | INTEGER | Request timeout in seconds (default: 30) |\n| --proxy | TEXT | Proxy URL in format \"http://username:password@host:port\" |\n| -s, --css-selector | TEXT | CSS selector to extract specific content from the page. It returns all matches. |\n| -p, --params | TEXT | Query parameters in format \"key=value\" (can be used multiple times) |\n| --follow-redirects / --no-follow-redirects | None | Whether to follow redirects (default: True) |\n| --verify / --no-verify | None | Whether to verify SSL certificates (default: True) |\n| --impersonate | TEXT | Browser to impersonate. Can be a single browser (e.g., Chrome) or a comma-separated list for random selection (e.g., Chrome, Firefox, Safari). |\n| --stealthy-headers / --no-stealthy-headers | None | Use stealthy browser headers (default: True) |\n\nOptions shared between `post` and `put` only:\n\n| Option | Input type | Description |\n|:-----------|:----------:|:----------------------------------------------------------------------------------------|\n| -d, --data | TEXT | Form data to include in the request body (as string, ex: \"param1=value1¶m2=value2\") |\n| -j, --json | TEXT | JSON data to include in the request body (as string) |\n\nExamples:\n\n```bash\n# Basic download\nscrapling extract get \"https://news.site.com\" news.md\n\n# Download with custom timeout\nscrapling extract get \"https://example.com\" content.txt --timeout 60\n\n# Extract only specific content using CSS selectors\nscrapling extract get \"https://blog.example.com\" articles.md --css-selector \"article\"\n\n# Send a request with cookies\nscrapling extract get \"https://scrapling.requestcatcher.com\" content.md --cookies \"session=abc123; user=john\"\n\n# Add user agent\nscrapling extract get \"https://api.site.com\" data.json -H \"User-Agent: MyBot 1.0\"\n\n# Add multiple headers\nscrapling extract get \"https://site.com\" page.html -H \"Accept: text/html\" -H \"Accept-Language: en-US\"\n```\n\n#### Key options (browsers)\n\nBoth (`fetch` / `stealthy-fetch`) share options:\n\n\n| Option | Input type | Description |\n|:-----------------------------------------|:----------:|:---------------------------------------------------------------------------------------------------------------------------------------------------------|\n| --headless / --no-headless | None | Run browser in headless mode (default: True) |\n| --disable-resources / --enable-resources | None | Drop unnecessary resources for speed boost (default: False) |\n| --network-idle / --no-network-idle | None | Wait for network idle (default: False) |\n| --real-chrome / --no-real-chrome | None | If you have a Chrome browser installed on your device, enable this, and the Fetcher will launch an instance of your browser and use it. (default: False) |\n| --timeout | INTEGER | Timeout in milliseconds (default: 30000) |\n| --wait | INTEGER | Additional wait time in milliseconds after page load (default: 0) |\n| -s, --css-selector | TEXT | CSS selector to extract specific content from the page.

Here's a quick overview of how to code with scrapling.\n\n### Basic Usage\nHTTP requests with session support\n```python\nfrom scrapling.fetchers import Fetcher, FetcherSession\n\nwith FetcherSession(impersonate='chrome') as session: # Use latest version of Chrome's TLS fingerprint\n page = session.get('https://quotes.toscrape.com/', stealthy_headers=True)\n quotes = page.css('.quote .text::text').getall()\n\n# Or use one-off requests\npage = Fetcher.get('https://quotes.toscrape.com/')\nquotes = page.css('.quote .text::text').getall()\n```\nAdvanced stealth mode\n```python\nfrom scrapling.fetchers import StealthyFetcher, StealthySession\n\nwith StealthySession(headless=True, solve_cloudflare=True) as session: # Keep the browser open until you finish\n page = session.fetch('https://nopecha.com/demo/cloudflare', google_search=False)\n data = page.css('#padded_content a').getall()\n\n# Or use one-off request style, it opens the browser for this request, then closes it after finishing\npage = StealthyFetcher.fetch('https://nopecha.com/demo/cloudflare')\ndata = page.css('#padded_content a').getall()\n```\nFull browser automation\n```python\nfrom scrapling.fetchers import DynamicFetcher, DynamicSession\n\nwith DynamicSession(headless=True, disable_resources=False, network_idle=True) as session: # Keep the browser open until you finish\n page = session.fetch('https://quotes.toscrape.com/', load_dom=False)\n data = page.xpath('//span[@class=\"text\"]/text()').getall() # XPath selector if you prefer it\n\n# Or use one-off request style, it opens the browser for this request, then closes it after finishing\npage = DynamicFetcher.fetch('https://quotes.toscrape.com/')\ndata = page.css('.quote .text::text').getall()\n```\n\n### Spiders\nBuild full crawlers with concurrent requests, multiple session types, and pause/resume:\n```python\nfrom scrapling.spiders import Spider, Request, Response\n\nclass QuotesSpider(Spider):\n name = \"quotes\"\n start_urls = [\"https://quotes.toscrape.com/\"]\n concurrent_requests = 10\n \n async def parse(self, response: Response):\n for quote in response.css('.quote'):\n yield {\n \"text\": quote.css('.text::text').get(),\n \"author\": quote.css('.author::text').get(),\n }\n \n next_page = response.css('.next a')\n if next_page:\n yield response.follow(next_page[0].attrib['href'])\n\nresult = QuotesSpider().start()\nprint(f\"Scraped {len(result.items)} quotes\")\nresult.items.to_json(\"quotes.json\")\n```\nUse multiple session types in a single spider:\n```python\nfrom scrapling.spiders import Spider, Request, Response\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession\n\nclass MultiSessionSpider(Spider):\n name = \"multi\"\n start_urls = [\"https://example.com/\"]\n \n def configure_sessions(self, manager):\n manager.add(\"fast\", FetcherSession(impersonate=\"chrome\"))\n manager.add(\"stealth\", AsyncStealthySession(headless=True), lazy=True)\n \n async def parse(self, response: Response):\n for link in response.css('a::attr(href)').getall():\n # Route protected pages through the stealth session\n if \"protected\" in link:\n yield Request(link, sid=\"stealth\")\n else:\n yield Request(link, sid=\"fast\", callback=self.parse) # explicit callback\n```\nPause and resume long crawls with checkpoints by running the spider like this:\n```python\nQuotesSpider(crawldir=\"./crawl_data\").start()\n```\nPress Ctrl+C to pause gracefully โ€” progress is saved automatically. Later, when you start the spider again, pass the same `crawldir`, and it will resume from where it stopped.\n\n### Advanced Parsing & Navigation\n```python\nfrom scrapling.fetchers import Fetcher\n\n# Rich element selection and navigation\npage = Fetcher.get('https://quotes.toscrape.com/')\n\n# Get quotes with multiple selection methods\nquotes = page.css('.quote') # CSS selector\nquotes = page.xpath('//div[@class=\"quote\"]') # XPath\nquotes = page.find_all('div', {'class': 'quote'}) # BeautifulSoup-style\n# Same as\nquotes = page.find_all('div', class_='quote')\nquotes = page.find_all(['div'], class_='quote')\nquotes = page.find_all(class_='quote') # and so on...\n# Find element by text content\nquotes = page.find_by_text('quote', tag='div')\n\n# Advanced navigation\nquote_text = page.css('.quote')[0].css('.text::text').get()\nquote_text = page.css('.quote').css('.text::text').getall() # Chained selectors\nfirst_quote = page.css('.quote')[0]\nauthor = first_quote.next_sibling.css('.author::text')\nparent_container = first_quote.parent\n\n# Element relationships and similarity\nsimilar_elements = first_quote.find_similar()\nbelow_elements = first_quote.below_elements()\n```\nYou can use the parser right away if you don't want to fetch websites like below:\n```python\nfrom scrapling.parser import Selector\n\npage = Selector(\"...\")\n```\nAnd it works precisely the same way!\n### Async Session Management Examples\n```python\nimport asyncio\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession, AsyncDynamicSession\n\nasync with FetcherSession(http3=True) as session: # `FetcherSession` is context-aware and can work in both sync/async patterns\n page1 = session.get('https://quotes.toscrape.com/')\n page2 = session.get('https://quotes.toscrape.com/', impersonate='firefox135')\n\n# Async session usage\nasync with AsyncStealthySession(max_pages=2) as session:\n tasks = []\n urls = ['https://example.com/page1', 'https://example.com/page2']\n \n for url in urls:\n task = session.fetch(url)\n tasks.append(task)\n \n print(session.get_pool_stats()) # Optional - The status of the browser tabs pool (busy/free/error)\n results = await asyncio.gather(*tasks)\n print(session.get_pool_stats())\n```\n\n## References\nYou already had a good glimpse of what the library can do.

All fetchers have separate session classes to keep the session running (e.g., a browser fetcher keeps the browser open until you finish all requests).\n\nFetchers are not wrappers built on top of other libraries. They use these libraries as an engine to request/fetch pages but add features the underlying engines don't have, while still fully leveraging and optimizing them for web scraping.\n\n## Fetchers Overview\n\nScrapling provides three different fetcher classes with their session classes; each fetcher is designed for a specific use case.\n\nThe following table compares them and can be quickly used for guidance.\n\n\n| Feature | Fetcher | DynamicFetcher | StealthyFetcher |\n|--------------------|---------------------------------------------------|-----------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------|\n| Relative speed | ๐Ÿ‡๐Ÿ‡๐Ÿ‡๐Ÿ‡๐Ÿ‡ | ๐Ÿ‡๐Ÿ‡๐Ÿ‡ | ๐Ÿ‡๐Ÿ‡๐Ÿ‡ |\n| Stealth | โญโญ | โญโญโญ | โญโญโญโญโญ |\n| Anti-Bot options | โญโญ | โญโญโญ | โญโญโญโญโญ |\n| JavaScript loading | โŒ | โœ… | โœ… |\n| Memory Usage | โญ | โญโญโญ | โญโญโญ |\n| Best used for | Basic scraping when HTTP requests alone can do it | - Dynamically loaded websites
- Small automation
- Small-Mid protections | - Dynamically loaded websites
- Small automation
- Small-Complicated protections |\n| Browser(s) | โŒ | Chromium and Google Chrome | Chromium and Google Chrome |\n| Browser API used | โŒ | PlayWright | PlayWright |\n| Setup Complexity | Simple | Simple | Simple |\n\n## Parser configuration in all fetchers\nAll fetchers share the same import method, as you will see in the upcoming pages\n```python\n>>> from scrapling.fetchers import Fetcher, AsyncFetcher, StealthyFetcher, DynamicFetcher\n```\nThen you use it right away without initializing like this, and it will use the default parser settings:\n```python\n>>> page = StealthyFetcher.fetch('https://example.com') \n```\nIf you want to configure the parser ([Selector class](parsing/main_classes.md#selector)) that will be used on the response before returning it for you, then do this first:\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> Fetcher.configure(adaptive=True, keep_comments=False, keep_cdata=False) # and the rest\n```\nor\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> Fetcher.adaptive=True\n>>> Fetcher.keep_comments=False\n>>> Fetcher.keep_cdata=False # and the rest\n```\nThen, continue your code as usual.\n\nThe available configuration arguments are: `adaptive`, `adaptive_domain`, `huge_tree`, `keep_comments`, `keep_cdata`, `storage`, and `storage_args`, which are the same ones you give to the [Selector](parsing/main_classes.md#selector) class. You can display the current configuration anytime by running `.display_config()`.\n\n**Info:** The `adaptive` argument is disabled by default; you must enable it to use that feature.\n\n### Set parser config per request\nAs you probably understand, the logic above for setting the parser config will apply globally to all requests/fetches made through that class, and it's intended for simplicity.\n\nIf your use case requires a different configuration for each request/fetch, you can pass a dictionary to the request method (`fetch`/`get`/`post`/...) to an argument named `selector_config`.\n\n## Response Object\nThe `Response` object is the same as the [Selector](parsing/main_classes.md#selector) class, but it has additional details about the response, like response headers, status, cookies, etc., as shown below:\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> page = Fetcher.get('https://example.com')\n\n>>> page.status # HTTP status code\n>>> page.reason # Status message\n>>> page.cookies # Response cookies as a dictionary\n>>> page.headers # Response headers\n>>> page.request_headers # Request headers\n>>> page.history # Response history of redirections, if any\n>>> page.body # Raw response body as bytes\n>>> page.encoding # Response encoding\n>>> page.meta # Response metadata dictionary (e.g., proxy used). Mainly helpful with the spiders system.\n```\nAll fetchers return the `Response` object.\n\n**Note:** Unlike the [Selector](parsing/main_classes.md#selector) class, the `Response` class's body is always bytes since v0.4." }, { "path": "agent-skill/Scrapling-Skill/references/fetching/dynamic.md", "content": "# Fetching dynamic websites\n\n`DynamicFetcher` (formerly `PlayWrightFetcher`) provides flexible browser automation with multiple configuration options and built-in stealth improvements.\n\nAs we will explain later, to automate the page, you need some knowledge of [Playwright's Page API](https://playwright.dev/python/docs/api/class-page).\n\n## Basic Usage\nYou have one primary way to import this Fetcher, which is the same for all fetchers.\n\n```python\n>>> from scrapling.fetchers import DynamicFetcher\n```\nCheck out how to configure the parsing options [here](choosing.md#parser-configuration-in-all-fetchers)\n\n**Note:** The async version of the `fetch` method is `async_fetch`.\n\nThis fetcher provides three main run options that can be combined as desired.\n\nWhich are:\n\n### 1. Vanilla Playwright\n```python\nDynamicFetcher.fetch('https://example.com')\n```\nUsing it in that manner will open a Chromium browser and load the page. There are optimizations for speed, and some stealth goes automatically under the hood, but other than that, there are no tricks or extra features unless you enable some; it's just a plain PlayWright API.\n\n### 2. Real Chrome\n```python\nDynamicFetcher.fetch('https://example.com', real_chrome=True)\n```\nIf you have a Google Chrome browser installed, use this option. It's the same as the first option, but it will use the Google Chrome browser you installed on your device instead of Chromium. This will make your requests look more authentic, so they're less detectable for better results.\n\nIf you don't have Google Chrome installed and want to use this option, you can use the command below in the terminal to install it for the library instead of installing it manually:\n```commandline\nplaywright install chrome\n```\n\n### 3. CDP Connection\n```python\nDynamicFetcher.fetch('https://example.com', cdp_url='ws://localhost:9222')\n```\nInstead of launching a browser locally (Chromium/Google Chrome), you can connect to a remote browser through the [Chrome DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/).\n\n\n**Notes:**\n* There was a `stealth` option here, but it was moved to the `StealthyFetcher` class, as explained on the next page, with additional features since version 0.3.13.\n* This makes it less confusing for new users, easier to maintain, and provides other benefits, as explained on the [StealthyFetcher page](stealthy.md).\n\n## Full list of arguments\nAll arguments for `DynamicFetcher` and its session classes:\n\n| Argument | Description | Optional |\n|:-------------------:|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:--------:|\n| url | Target url | โŒ |\n| headless | Pass `True` to run the browser in headless/hidden (**default**) or `False` for headful/visible mode. | โœ”๏ธ |\n| disable_resources | Drop requests for unnecessary resources for a speed boost. Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`. | โœ”๏ธ |\n| cookies | Set cookies for the next request. | โœ”๏ธ |\n| useragent | Pass a useragent string to be used. **Otherwise, the fetcher will generate and use a real Useragent of the same browser and version.** | โœ”๏ธ |\n| network_idle | Wait for the page until there are no network connections for at least 500 ms. | โœ”๏ธ |\n| load_dom | Enabled by default, wait for all JavaScript on page(s) to fully load and execute (wait for the `domcontentloaded` state). | โœ”๏ธ |\n| timeout | The timeout (milliseconds) used in all operations and waits through the page. The default is 30,000 ms (30 seconds). | โœ”๏ธ |\n| wait | The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the `Response` object. | โœ”๏ธ |\n| page_action | Added for automation. Pass a function that takes the `page` object and does the necessary automation. | โœ”๏ธ |\n| wait_selector | Wait for a specific css selector to be in a specific state. | โœ”๏ธ |\n| init_script | An absolute path to a JavaScript file to be executed on page creation for all pages in this session. | โœ”๏ธ |\n| wait_selector_state | Scrapling will wait for the given state to be fulfilled for the selector given with `wait_selector`. _Default state is `attached`._ | โœ”๏ธ |\n| google_search | Enabled by default, Scrapling will set a Google referer header. | โœ”๏ธ |\n| extra_headers | A dictionary of extra headers to add to the request. _The referer set by `google_search` takes priority over the referer set here if used together._ | โœ”๏ธ |\n| proxy | The proxy to be used with requests. It can be a string or a dictionary with only the keys 'server', 'username', and 'password'. | โœ”๏ธ |\n| real_chrome | If you have a Chrome browser installed on your device, enable this, and the Fetcher will launch and use an instance of your browser. | โœ”๏ธ |\n| locale | Specify user locale, for example, `en-GB`, `de-DE`, etc. Locale will affect `navigator.language` value, `Accept-Language` request header value, as well as number and date formatting rules. Defaults to the system default locale. | โœ”๏ธ |\n| timezone_id | Changes the timezone of the browser. Defaults to the system timezone. | โœ”๏ธ |\n| cdp_url | Instead of launching a new browser instance, connect to this CDP URL to control real browsers through CDP. | โœ”๏ธ |\n| user_data_dir | Path to a User Data Directory, which stores browser session data like cookies and local storage. The default is to create a temporary directory. **Only Works with sessions** | โœ”๏ธ |\n| extra_flags | A list of additional browser flags to pass to the browser on launch. | โœ”๏ธ |\n| additional_args | Additional arguments to be passed to Playwright's context as additional settings, and they take higher priority than Scrapling's settings. | โœ”๏ธ |\n| selector_config | A dictionary of custom parsing arguments to be used when creating the final `Selector`/`Response` class. | โœ”๏ธ |\n| blocked_domains | A set of domain names to block requests to. Subdomains are also matched (e.g., `\"example.com\"` blocks `\"sub.example.com\"` too). | โœ”๏ธ |\n| proxy_rotator | A `ProxyRotator` instance for automatic proxy rotation. Cannot be combined with `proxy`. | โœ”๏ธ |\n| retries | Number of retry attempts for failed requests. Defaults to 3. | โœ”๏ธ |\n| retry_delay | Seconds to wait between retry attempts. Defaults to 1. | โœ”๏ธ |\n\nIn session classes, all these arguments can be set globally for the session. Still, you can configure each request individually by passing some of the arguments here that can be configured on the browser tab level like: `google_search`, `timeout`, `wait`, `page_action`, `extra_headers`, `disable_resources`, `wait_selector`, `wait_selector_state`, `network_idle`, `load_dom`, `blocked_domains`, `proxy`, and `selector_config`.\n\n**Notes:**\n1. The `disable_resources` option made requests ~25% faster in tests for some websites and can help save proxy usage, but be careful with it, as it can cause some websites to never finish loading.\n2. The `google_search` argument is enabled by default for all requests, setting the referer to `https://www.google.com/`. If used together with `extra_headers`, it takes priority over the referer set there.\n3. Since version 0.3.13, the `stealth` option has been removed here in favor of the `StealthyFetcher` class, and the `hide_canvas` option has been moved to it. The `disable_webgl` argument has been moved to the `StealthyFetcher` class and renamed as `allow_webgl`.\n4. If you didn't set a user agent and enabled headless mode, the fetcher will generate a real user agent for the same browser version and use it. If you didn't set a user agent and didn't enable headless mode, the fetcher will use the browser's default user agent, which is the same as in standard browsers in the latest versions.\n\n\n## Examples\n\n### Resource Control\n\n```python\n# Disable unnecessary resources\npage = DynamicFetcher.fetch('https://example.com', disable_resources=True) # Blocks fonts, images, media, etc.\n```\n\n### Domain Blocking\n\n```python\n# Block requests to specific domains (and their subdomains)\npage = DynamicFetcher.fetch('https://example.com', blocked_domains={\"ads.example.com\", \"tracker.net\"})\n```\n\n### Network Control\n\n```python\n# Wait for network idle (Consider fetch to be finished when there are no network connections for at least 500 ms)\npage = DynamicFetcher.fetch('https://example.com', network_idle=True)\n\n# Custom timeout (in milliseconds)\npage = DynamicFetcher.fetch('https://example.com', timeout=30000) # 30 seconds\n\n# Proxy support (It can also be a dictionary with only the keys 'server', 'username', and 'password'.)\npage = DynamicFetcher.fetch('https://example.com', proxy='http://username:password@host:port')\n```\n\n### Proxy Rotation\n\n```python\nfrom scrapling.fetchers import DynamicSession, ProxyRotator\n\n# Set up proxy rotation\nrotator = ProxyRotator([\n \"http://proxy1:8080\",\n \"http://proxy2:8080\",\n \"http://proxy3:8080\",\n])\n\n# Use with session - rotates proxy automatically with each request\nwith DynamicSession(proxy_rotator=rotator, headless=True) as session:\n page1 = session.fetch('https://example1.com')\n page2 = session.fetch('https://example2.com')\n\n # Override rotator for a specific request\n page3 = session.fetch('https://example3.com', proxy='http://specific-proxy:8080')\n```\n\n**Warning:** By default, all browser-based fetchers and sessions use a persistent browser context with a pool of tabs. However, since browsers can't set a proxy per tab, when you use a `ProxyRotator`, the fetcher will automatically open a separate context for each proxy, with one tab per context. Once the tab's job is done, both the tab and its context are closed.\n\n### Downloading Files\n\n```python\npage = DynamicFetcher.fetch('https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/main_cover.png')\n\nwith open(file='main_cover.png', mode='wb') as f:\n f.write(page.body)\n```\n\nThe `body` attribute of the `Response` object always returns `bytes`.\n\n### Browser Automation\nThis is where your knowledge about [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) comes into play. The function you pass here takes the page object from Playwright's API, performs the desired action, and then the fetcher continues.\n\nThis function is executed immediately after waiting for `network_idle` (if enabled) and before waiting for the `wait_selector` argument, allowing it to be used for purposes beyond automation. You can alter the page as you want.\n\nIn the example below, I used the pages' [mouse events](https://playwright.dev/python/docs/api/class-mouse) to scroll the page with the mouse wheel, then move the mouse.\n```python\nfrom playwright.sync_api import Page\n\ndef scroll_page(page: Page):\n page.mouse.wheel(10, 0)\n page.mouse.move(100, 400)\n page.mouse.up()\n\npage = DynamicFetcher.fetch('https://example.com', page_action=scroll_page)\n```\nOf course, if you use the async fetch version, the function must also be async.\n```python\nfrom playwright.async_api import Page\n\nasync def scroll_page(page: Page):\n await page.mouse.wheel(10, 0)\n await page.mouse.move(100, 400)\n await page.mouse.up()\n\npage = await DynamicFetcher.async_fetch('https://example.com', page_action=scroll_page)\n```\n\n### Wait Conditions\n\n```python\n# Wait for the selector\npage = DynamicFetcher.fetch(\n 'https://example.com',\n wait_selector='h1',\n wait_selector_state='visible'\n)\n```\nThis is the last wait the fetcher will do before returning the response (if enabled). You pass a CSS selector to the `wait_selector` argument, and the fetcher will wait for the state you passed in the `wait_selector_state` argument to be fulfilled. If you didn't pass a state, the default would be `attached`, which means it will wait for the element to be present in the DOM.\n\nAfter that, if `load_dom` is enabled (the default), the fetcher will check again to see if all JavaScript files are loaded and executed (in the `domcontentloaded` state) or continue waiting. If you have enabled `network_idle`, the fetcher will wait for `network_idle` to be fulfilled again, as explained above.\n\nThe states the fetcher can wait for can be any of the following ([source](https://playwright.dev/python/docs/api/class-page#page-wait-for-selector)):\n\n- `attached`: Wait for an element to be present in the DOM.\n- `detached`: Wait for an element to not be present in the DOM.\n- `visible`: wait for an element to have a non-empty bounding box and no `visibility:hidden`. Note that an element without any content or with `display:none` has an empty bounding box and is not considered visible.\n- `hidden`: wait for an element to be either detached from the DOM, or have an empty bounding box, or `visibility:hidden`. This is opposite to the `'visible'` option.\n\n### Some Stealth Features\n\n```python\npage = DynamicFetcher.fetch(\n 'https://example.com',\n google_search=True,\n useragent='Mozilla/5.0...', # Custom user agent\n locale='en-US', # Set browser locale\n)\n```\n\n### General example\n```python\nfrom scrapling.fetchers import DynamicFetcher\n\ndef scrape_dynamic_content():\n # Use Playwright for JavaScript content\n page = DynamicFetcher.fetch(\n 'https://example.com/dynamic',\n network_idle=True,\n wait_selector='.content'\n )\n \n # Extract dynamic content\n content = page.css('.content')\n \n return {\n 'title': content.css('h1::text').get(),\n 'items': [\n item.text for item in content.css('.item')\n ]\n }\n```\n\n## Session Management\n\nTo keep the browser open until you make multiple requests with the same configuration, use `DynamicSession`/`AsyncDynamicSession` classes. Those classes can accept all the arguments that the `fetch` function can take, which enables you to specify a config for the entire session.\n\n```python\nfrom scrapling.fetchers import DynamicSession\n\n# Create a session with default configuration\nwith DynamicSession(\n headless=True,\n disable_resources=True,\n real_chrome=True\n) as session:\n # Make multiple requests with the same browser instance\n page1 = session.fetch('https://example1.com')\n page2 = session.fetch('https://example2.com')\n page3 = session.fetch('https://dynamic-site.com')\n \n # All requests reuse the same tab on the same browser instance\n```\n\n### Async Session Usage\n\n```python\nimport asyncio\nfrom scrapling.fetchers import AsyncDynamicSession\n\nasync def scrape_multiple_sites():\n async with AsyncDynamicSession(\n network_idle=True,\n timeout=30000,\n max_pages=3\n ) as session:\n # Make async requests with shared browser configuration\n pages = await asyncio.gather(\n session.fetch('https://spa-app1.com'),\n session.fetch('https://spa-app2.com'),\n session.fetch('https://dynamic-content.com')\n )\n return pages\n```\n\nYou may have noticed the `max_pages` argument. This is a new argument that enables the fetcher to create a **rotating pool of Browser tabs**. Instead of using a single tab for all your requests, you set a limit on the maximum number of pages that can be displayed at once. With each request, the library will close all tabs that have finished their task and check if the number of the current tabs is lower than the maximum allowed number of pages/tabs, then:\n\n1. If you are within the allowed range, the fetcher will create a new tab for you, and then all is as normal.\n2. Otherwise, it will keep checking every subsecond if creating a new tab is allowed or not for 60 seconds, then raise `TimeoutError`. This can happen when the website you are fetching becomes unresponsive.\n\nThis logic allows for multiple URLs to be fetched at the same time in the same browser, which saves a lot of resources, but most importantly, is so fast :)\n\nIn versions 0.3 and 0.3.1, the pool was reusing finished tabs to save more resources/time. That logic proved flawed, as it's nearly impossible to protect pages/tabs from contamination by the previous configuration used in the request before this one.\n\n### Session Benefits\n\n- **Browser reuse**: Much faster subsequent requests by reusing the same browser instance.\n- **Cookie persistence**: Automatic cookie and session state handling as any browser does automatically.\n- **Consistent fingerprint**: Same browser fingerprint across all requests.\n- **Memory efficiency**: Better resource usage compared to launching new browsers with each fetch.\n\n## When to Use\n\nUse DynamicFetcher when:\n\n- Need browser automation\n- Want multiple browser options\n- Using a real Chrome browser\n- Need custom browser config\n- Want a few stealth options \n\nIf you want more stealth and control without much config, check out the [StealthyFetcher](stealthy.md)." }, { "path": "agent-skill/Scrapling-Skill/references/fetching/static.md", "content": "# HTTP requests\n\nThe `Fetcher` class provides rapid and lightweight HTTP requests using the high-performance `curl_cffi` library with a lot of stealth capabilities.\n\n## Basic Usage\nImport the Fetcher (same import pattern for all fetchers):\n\n```python\n>>> from scrapling.fetchers import Fetcher\n```\nCheck out how to configure the parsing options [here](choosing.md#parser-configuration-in-all-fetchers)\n\n### Shared arguments\nAll methods for making requests here share some arguments, so let's discuss them first.\n\n- **url**: The targeted URL\n- **stealthy_headers**: If enabled (default), it creates and adds real browser headers. It also sets a Google referer header.\n- **follow_redirects**: As the name implies, tell the fetcher to follow redirections. **Enabled by default**\n- **timeout**: The number of seconds to wait for each request to be finished. **Defaults to 30 seconds**.\n- **retries**: The number of retries that the fetcher will do for failed requests. **Defaults to three retries**.\n- **retry_delay**: Number of seconds to wait between retry attempts. **Defaults to 1 second**.\n- **impersonate**: Impersonate specific browsers' TLS fingerprints. Accepts browser strings or a list of them like `\"chrome110\"`, `\"firefox102\"`, `\"safari15_5\"` to use specific versions or `\"chrome\"`, `\"firefox\"`, `\"safari\"`, `\"edge\"` to automatically use the latest version available. This makes your requests appear to come from real browsers at the TLS level. If you pass it a list of strings, it will choose a random one with each request. **Defaults to the latest available Chrome version.**\n- **http3**: Use HTTP/3 protocol for requests. **Defaults to False**. It might be problematic if used with `impersonate`.\n- **cookies**: Cookies to use in the request. Can be a dictionary of `nameโ†’value` or a list of dictionaries.\n- **proxy**: As the name implies, the proxy for this request is used to route all traffic (HTTP and HTTPS). The format accepted here is `http://username:password@localhost:8030`.\n- **proxy_auth**: HTTP basic auth for proxy, tuple of (username, password).\n- **proxies**: Dict of proxies to use. Format: `{\"http\": proxy_url, \"https\": proxy_url}`.\n- **proxy_rotator**: A `ProxyRotator` instance for automatic proxy rotation. Cannot be combined with `proxy` or `proxies`.\n- **headers**: Headers to include in the request. Can override any header generated by the `stealthy_headers` argument\n- **max_redirects**: Maximum number of redirects. **Defaults to 30**, use -1 for unlimited.\n- **verify**: Whether to verify HTTPS certificates. **Defaults to True**.\n- **cert**: Tuple of (cert, key) filenames for the client certificate.\n- **selector_config**: A dictionary of custom parsing arguments to be used when creating the final `Selector`/`Response` class.\n\n**Notes:**\n1. The currently available browsers to impersonate are (`\"edge\"`, `\"chrome\"`, `\"chrome_android\"`, `\"safari\"`, `\"safari_beta\"`, `\"safari_ios\"`, `\"safari_ios_beta\"`, `\"firefox\"`, `\"tor\"`)\n2. The available browsers to impersonate, along with their corresponding versions, are automatically displayed in the argument autocompletion and updated with each `curl_cffi` update.\n3. If any of the arguments `impersonate` or `stealthy_headers` are enabled, the fetchers will automatically generate real browser headers that match the browser version used.\n\nOther than this, for further customization, you can pass any arguments that `curl_cffi` supports for any method if that method doesn't already support them.\n\n### HTTP Methods\nThere are additional arguments for each method, depending on the method, such as `params` for GET requests and `data`/`json` for POST/PUT/DELETE requests.\n\nExamples are the best way to explain this:\n\n> Hence: `OPTIONS` and `HEAD` methods are not supported.\n#### GET\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> # Basic GET\n>>> page = Fetcher.get('https://example.com')\n>>> page = Fetcher.get('https://scrapling.requestcatcher.com/get', stealthy_headers=True, follow_redirects=True)\n>>> page = Fetcher.get('https://scrapling.requestcatcher.com/get', proxy='http://username:password@localhost:8030')\n>>> # With parameters\n>>> page = Fetcher.get('https://example.com/search', params={'q': 'query'})\n>>>\n>>> # With headers\n>>> page = Fetcher.get('https://example.com', headers={'User-Agent': 'Custom/1.0'})\n>>> # Basic HTTP authentication\n>>> page = Fetcher.get(\"https://example.com\", auth=(\"my_user\", \"password123\"))\n>>> # Browser impersonation\n>>> page = Fetcher.get('https://example.com', impersonate='chrome')\n>>> # HTTP/3 support\n>>> page = Fetcher.get('https://example.com', http3=True)\n```\nAnd for asynchronous requests, it's a small adjustment \n```python\n>>> from scrapling.fetchers import AsyncFetcher\n>>> # Basic GET\n>>> page = await AsyncFetcher.get('https://example.com')\n>>> page = await AsyncFetcher.get('https://scrapling.requestcatcher.com/get', stealthy_headers=True, follow_redirects=True)\n>>> page = await AsyncFetcher.get('https://scrapling.requestcatcher.com/get', proxy='http://username:password@localhost:8030')\n>>> # With parameters\n>>> page = await AsyncFetcher.get('https://example.com/search', params={'q': 'query'})\n>>>\n>>> # With headers\n>>> page = await AsyncFetcher.get('https://example.com', headers={'User-Agent': 'Custom/1.0'})\n>>> # Basic HTTP authentication\n>>> page = await AsyncFetcher.get(\"https://example.com\", auth=(\"my_user\", \"password123\"))\n>>> # Browser impersonation\n>>> page = await AsyncFetcher.get('https://example.com', impersonate='chrome110')\n>>> # HTTP/3 support\n>>> page = await AsyncFetcher.get('https://example.com', http3=True)\n```\nThe `page` object in all cases is a [Response](choosing.md#response-object) object, which is a [Selector](parsing/main_classes.md#selector), so you can use it directly\n```python\n>>> page.css('.something.something')\n\n>>> page = Fetcher.get('https://api.github.com/events')\n>>> page.json()\n[{'id': '',\n 'type': 'PushEvent',\n 'actor': {'id': '',\n 'login': '',\n 'display_login': '',\n 'gravatar_id': '',\n 'url': 'https://api.github.com/users/',\n 'avatar_url': 'https://avatars.githubusercontent.com/u/'},\n 'repo': {'id': '',\n...\n```\n#### POST\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> # Basic POST\n>>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, params={'q': 'query'})\n>>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, stealthy_headers=True, follow_redirects=True)\n>>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030', impersonate=\"chrome\")\n>>> # Another example of form-encoded data\n>>> page = Fetcher.post('https://example.com/submit', data={'username': 'user', 'password': 'pass'}, http3=True)\n>>> # JSON data\n>>> page = Fetcher.post('https://example.com/api', json={'key': 'value'})\n```\nAnd for asynchronous requests, it's a small adjustment\n```python\n>>> from scrapling.fetchers import AsyncFetcher\n>>> # Basic POST\n>>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'})\n>>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, stealthy_headers=True, follow_redirects=True)\n>>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030', impersonate=\"chrome\")\n>>> # Another example of form-encoded data\n>>> page = await AsyncFetcher.post('https://example.com/submit', data={'username': 'user', 'password': 'pass'}, http3=True)\n>>> # JSON data\n>>> page = await AsyncFetcher.post('https://example.com/api', json={'key': 'value'})\n```\n#### PUT\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> # Basic PUT\n>>> page = Fetcher.put('https://example.com/update', data={'status': 'updated'})\n>>> page = Fetcher.put('https://example.com/update', data={'status': 'updated'}, stealthy_headers=True, follow_redirects=True, impersonate=\"chrome\")\n>>> page = Fetcher.put('https://example.com/update', data={'status': 'updated'}, proxy='http://username:password@localhost:8030')\n>>> # Another example of form-encoded data\n>>> page = Fetcher.put(\"https://scrapling.requestcatcher.com/put\", data={'key': ['value1', 'value2']})\n```\nAnd for asynchronous requests, it's a small adjustment\n```python\n>>> from scrapling.fetchers import AsyncFetcher\n>>> # Basic PUT\n>>> page = await AsyncFetcher.put('https://example.com/update', data={'status': 'updated'})\n>>> page = await AsyncFetcher.put('https://example.com/update', data={'status': 'updated'}, stealthy_headers=True, follow_redirects=True, impersonate=\"chrome\")\n>>> page = await AsyncFetcher.put('https://example.com/update', data={'status': 'updated'}, proxy='http://username:password@localhost:8030')\n>>> # Another example of form-encoded data\n>>> page = await AsyncFetcher.put(\"https://scrapling.requestcatcher.com/put\", data={'key': ['value1', 'value2']})\n```\n\n#### DELETE\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> page = Fetcher.delete('https://example.com/resource/123')\n>>> page = Fetcher.delete('https://example.com/resource/123', stealthy_headers=True, follow_redirects=True, impersonate=\"chrome\")\n>>> page = Fetcher.delete('https://example.com/resource/123', proxy='http://username:password@localhost:8030')\n```\nAnd for asynchronous requests, it's a small adjustment\n```python\n>>> from scrapling.fetchers import AsyncFetcher\n>>> page = await AsyncFetcher.delete('https://example.com/resource/123')\n>>> page = await AsyncFetcher.delete('https://example.com/resource/123', stealthy_headers=True, follow_redirects=True, impersonate=\"chrome\")\n>>> page = await AsyncFetcher.delete('https://example.com/resource/123', proxy='http://username:password@localhost:8030')\n```\n\n## Session Management\n\nFor making multiple requests with the same configuration, use the `FetcherSession` class. It can be used in both synchronous and asynchronous code without issue; the class automatically detects and changes the session type, without requiring a different import.\n\nThe `FetcherSession` class can accept nearly all the arguments that the methods can take, which enables you to specify a config for the entire session and later choose a different config for one of the requests effortlessly, as you will see in the following examples.\n\n```python\nfrom scrapling.fetchers import FetcherSession\n\n# Create a session with default configuration\nwith FetcherSession(\n impersonate='chrome',\n http3=True,\n stealthy_headers=True,\n timeout=30,\n retries=3\n) as session:\n # Make multiple requests with the same settings and the same cookies\n page1 = session.get('https://scrapling.requestcatcher.com/get')\n page2 = session.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'})\n page3 = session.get('https://api.github.com/events')\n\n # All requests share the same session and connection pool\n```\n\nYou can also use a `ProxyRotator` with `FetcherSession` for automatic proxy rotation across requests:\n\n```python\nfrom scrapling.fetchers import FetcherSession, ProxyRotator\n\nrotator = ProxyRotator([\n 'http://proxy1:8080',\n 'http://proxy2:8080',\n 'http://proxy3:8080',\n])\n\nwith FetcherSession(proxy_rotator=rotator, impersonate='chrome') as session:\n # Each request automatically uses the next proxy in rotation\n page1 = session.get('https://example.com/page1')\n page2 = session.get('https://example.com/page2')\n\n # You can check which proxy was used via the response metadata\n print(page1.meta['proxy'])\n```\n\nYou can also override the session proxy (or rotator) for a specific request by passing `proxy=` directly to the request method:\n\n```python\nwith FetcherSession(proxy='http://default-proxy:8080') as session:\n # Uses the session proxy\n page1 = session.get('https://example.com/page1')\n\n # Override the proxy for this specific request\n page2 = session.get('https://example.com/page2', proxy='http://special-proxy:9090')\n```\n\nAnd here's an async example\n\n```python\nasync with FetcherSession(impersonate='firefox', http3=True) as session:\n # All standard HTTP methods available\n response = await session.get('https://example.com')\n response = await session.post('https://scrapling.requestcatcher.com/post', json={'data': 'value'})\n response = await session.put('https://scrapling.requestcatcher.com/put', data={'update': 'info'})\n response = await session.delete('https://scrapling.requestcatcher.com/delete')\n```\nor better\n```python\nimport asyncio\nfrom scrapling.fetchers import FetcherSession\n\n# Async session usage\nasync with FetcherSession(impersonate=\"safari\") as session:\n urls = ['https://example.com/page1', 'https://example.com/page2']\n\n tasks = [\n session.get(url) for url in urls\n ]\n\n pages = await asyncio.gather(*tasks)\n```\n\nThe `Fetcher` class uses `FetcherSession` to create a temporary session with each request you make.\n\n### Session Benefits\n\n- **A lot faster**: 10 times faster than creating a single session for each request\n- **Cookie persistence**: Automatic cookie handling across requests\n- **Resource efficiency**: Better memory and CPU usage for multiple requests\n- **Centralized configuration**: Single place to manage request settings\n\n## Examples\nSome well-rounded examples to aid newcomers to Web Scraping\n\n### Basic HTTP Request\n\n```python\nfrom scrapling.fetchers import Fetcher\n\n# Make a request\npage = Fetcher.get('https://example.com')\n\n# Check the status\nif page.status == 200:\n # Extract title\n title = page.css('title::text').get()\n print(f\"Page title: {title}\")\n\n # Extract all links\n links = page.css('a::attr(href)').getall()\n print(f\"Found {len(links)} links\")\n```\n\n### Product Scraping\n\n```python\nfrom scrapling.fetchers import Fetcher\n\ndef scrape_products():\n page = Fetcher.get('https://example.com/products')\n \n # Find all product elements\n products = page.css('.product')\n \n results = []\n for product in products:\n results.append({\n 'title': product.css('.title::text').get(),\n 'price': product.css('.price::text').re_first(r'\\d+\\.\\d{2}'),\n 'description': product.css('.description::text').get(),\n 'in_stock': product.has_class('in-stock')\n })\n \n return results\n```\n\n### Downloading Files\n\n```python\nfrom scrapling.fetchers import Fetcher\n\npage = Fetcher.get('https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/main_cover.png')\nwith open(file='main_cover.png', mode='wb') as f:\n f.write(page.body)\n```\n\n### Pagination Handling\n\n```python\nfrom scrapling.fetchers import Fetcher\n\ndef scrape_all_pages():\n base_url = 'https://example.com/products?page={}'\n page_num = 1\n all_products = []\n \n while True:\n # Get current page\n page = Fetcher.get(base_url.format(page_num))\n \n # Find products\n products = page.css('.product')\n if not products:\n break\n \n # Process products\n for product in products:\n all_products.append({\n 'name': product.css('.name::text').get(),\n 'price': product.css('.price::text').get()\n })\n \n # Next page\n page_num += 1\n \n return all_products\n```\n\n### Form Submission\n\n```python\nfrom scrapling.fetchers import Fetcher\n\n# Submit login form\nresponse = Fetcher.post(\n 'https://example.com/login',\n data={\n 'username': 'user@example.com',\n 'password': 'password123'\n }\n)\n\n# Check login success\nif response.status == 200:\n # Extract user info\n user_name = response.css('.user-name::text').get()\n print(f\"Logged in as: {user_name}\")\n```\n\n### Table Extraction\n\n```python\nfrom scrapling.fetchers import Fetcher\n\ndef extract_table():\n page = Fetcher.get('https://example.com/data')\n \n # Find table\n table = page.css('table')[0]\n \n # Extract headers\n headers = [\n th.text for th in table.css('thead th')\n ]\n \n # Extract rows\n rows = []\n for row in table.css('tbody tr'):\n cells = [td.text for td in row.css('td')]\n rows.append(dict(zip(headers, cells)))\n \n return rows\n```\n\n### Navigation Menu\n\n```python\nfrom scrapling.fetchers import Fetcher\n\ndef extract_menu():\n page = Fetcher.get('https://example.com')\n \n # Find navigation\n nav = page.css('nav')[0]\n \n menu = {}\n for item in nav.css('li'):\n links = item.css('a')\n if links:\n link = links[0]\n menu[link.text] = {\n 'url': link['href'],\n 'has_submenu': bool(item.css('.submenu'))\n }\n \n return menu\n```\n\n## When to Use\n\nUse `Fetcher` when:\n\n- Need rapid HTTP requests.\n- Want minimal overhead.\n- Don't need JavaScript execution (the website can be scraped through requests).\n- Need some stealth features (ex, the targeted website is using protection but doesn't use JavaScript challenges).\n\nUse `FetcherSession` when:\n\n- Making multiple requests to the same or different sites.\n- Need to maintain cookies/authentication between requests.\n- Want connection pooling for better performance.\n- Require consistent configuration across requests.\n- Working with APIs that require a session state.\n\nUse other fetchers when:\n\n- Need browser automation.\n- Need advanced anti-bot/stealth capabilities.\n- Need JavaScript support or interacting with dynamic content" }, { "path": "agent-skill/Scrapling-Skill/references/fetching/stealthy.md", "content": "# StealthyFetcher\n\n`StealthyFetcher` is a stealthy browser-based fetcher similar to [DynamicFetcher](dynamic.md), using [Playwright's API](https://playwright.dev/python/docs/intro).

Before jumping to the [examples](#examples), here's the full list of arguments\n\n\n| Argument | Description | Optional |\n|:-------------------:|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:--------:|\n| url | Target url | โŒ |\n| headless | Pass `True` to run the browser in headless/hidden (**default**) or `False` for headful/visible mode. | โœ”๏ธ |\n| disable_resources | Drop requests for unnecessary resources for a speed boost. Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`. | โœ”๏ธ |\n| cookies | Set cookies for the next request. | โœ”๏ธ |\n| useragent | Pass a useragent string to be used. **Otherwise, the fetcher will generate and use a real Useragent of the same browser and version.** | โœ”๏ธ |\n| network_idle | Wait for the page until there are no network connections for at least 500 ms. | โœ”๏ธ |\n| load_dom | Enabled by default, wait for all JavaScript on page(s) to fully load and execute (wait for the `domcontentloaded` state). | โœ”๏ธ |\n| timeout | The timeout (milliseconds) used in all operations and waits through the page. The default is 30,000 ms (30 seconds). | โœ”๏ธ |\n| wait | The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the `Response` object. | โœ”๏ธ |\n| page_action | Added for automation. Pass a function that takes the `page` object and does the necessary automation. | โœ”๏ธ |\n| wait_selector | Wait for a specific css selector to be in a specific state. | โœ”๏ธ |\n| init_script | An absolute path to a JavaScript file to be executed on page creation for all pages in this session. | โœ”๏ธ |\n| wait_selector_state | Scrapling will wait for the given state to be fulfilled for the selector given with `wait_selector`. _Default state is `attached`._ | โœ”๏ธ |\n| google_search | Enabled by default, Scrapling will set a Google referer header. | โœ”๏ธ |\n| extra_headers | A dictionary of extra headers to add to the request. _The referer set by `google_search` takes priority over the referer set here if used together._ | โœ”๏ธ |\n| proxy | The proxy to be used with requests. It can be a string or a dictionary with only the keys 'server', 'username', and 'password'. | โœ”๏ธ |\n| real_chrome | If you have a Chrome browser installed on your device, enable this, and the Fetcher will launch and use an instance of your browser. | โœ”๏ธ |\n| locale | Specify user locale, for example, `en-GB`, `de-DE`, etc. Locale will affect `navigator.language` value, `Accept-Language` request header value, as well as number and date formatting rules. Defaults to the system default locale. | โœ”๏ธ |\n| timezone_id | Changes the timezone of the browser. Defaults to the system timezone. | โœ”๏ธ |\n| cdp_url | Instead of launching a new browser instance, connect to this CDP URL to control real browsers through CDP. | โœ”๏ธ |\n| user_data_dir | Path to a User Data Directory, which stores browser session data like cookies and local storage. The default is to create a temporary directory. **Only Works with sessions** | โœ”๏ธ |\n| extra_flags | A list of additional browser flags to pass to the browser on launch. | โœ”๏ธ |\n| solve_cloudflare | When enabled, fetcher solves all types of Cloudflare's Turnstile/Interstitial challenges before returning the response to you. | โœ”๏ธ |\n| block_webrtc | Forces WebRTC to respect proxy settings to prevent local IP address leak. | โœ”๏ธ |\n| hide_canvas | Add random noise to canvas operations to prevent fingerprinting. | โœ”๏ธ |\n| allow_webgl | Enabled by default. Disabling it disables WebGL and WebGL 2.0 support entirely. Disabling WebGL is not recommended, as many WAFs now check if WebGL is enabled. | โœ”๏ธ |\n| additional_args | Additional arguments to be passed to Playwright's context as additional settings, and they take higher priority than Scrapling's settings. | โœ”๏ธ |\n| selector_config | A dictionary of custom parsing arguments to be used when creating the final `Selector`/`Response` class. | โœ”๏ธ |\n| blocked_domains | A set of domain names to block requests to. Subdomains are also matched (e.g., `\"example.com\"` blocks `\"sub.example.com\"` too). | โœ”๏ธ |\n| proxy_rotator | A `ProxyRotator` instance for automatic proxy rotation. Cannot be combined with `proxy`. | โœ”๏ธ |\n| retries | Number of retry attempts for failed requests. Defaults to 3. | โœ”๏ธ |\n| retry_delay | Seconds to wait between retry attempts. Defaults to 1. | โœ”๏ธ |\n\nIn session classes, all these arguments can be set globally for the session. Still, you can configure each request individually by passing some of the arguments here that can be configured on the browser tab level like: `google_search`, `timeout`, `wait`, `page_action`, `extra_headers`, `disable_resources`, `wait_selector`, `wait_selector_state`, `network_idle`, `load_dom`, `solve_cloudflare`, `blocked_domains`, `proxy`, and `selector_config`.\n\n**Notes:**\n\n1. It's basically the same arguments as [DynamicFetcher](dynamic.md) class, but with these additional arguments: `solve_cloudflare`, `block_webrtc`, `hide_canvas`, and `allow_webgl`.\n2. The `disable_resources` option made requests ~25% faster in tests for some websites and can help save proxy usage, but be careful with it, as it can cause some websites to never finish loading.\n3. The `google_search` argument is enabled by default for all requests, setting the referer to `https://www.google.com/`. If used together with `extra_headers`, it takes priority over the referer set there.\n4. If you didn't set a user agent and enabled headless mode, the fetcher will generate a real user agent for the same browser version and use it. If you didn't set a user agent and didn't enable headless mode, the fetcher will use the browser's default user agent, which is the same as in standard browsers in the latest versions.\n\n## Examples\n\n### Cloudflare and stealth options\n\n```python\n# Automatic Cloudflare solver\npage = StealthyFetcher.fetch('https://nopecha.com/demo/cloudflare', solve_cloudflare=True)\n\n# Works with other stealth options\npage = StealthyFetcher.fetch(\n 'https://protected-site.com',\n solve_cloudflare=True,\n block_webrtc=True,\n real_chrome=True,\n hide_canvas=True,\n google_search=True,\n proxy='http://username:password@host:port', # It can also be a dictionary with only the keys 'server', 'username', and 'password'.\n)\n```\n\nThe `solve_cloudflare` parameter enables automatic detection and solving all types of Cloudflare's Turnstile/Interstitial challenges:\n\n- JavaScript challenges (managed)\n- Interactive challenges (clicking verification boxes)\n- Invisible challenges (automatic background verification)\n\nAnd even solves the custom pages with embedded captcha.\n\n**Important notes:**\n\n1. Sometimes, with websites that use custom implementations, you will need to use `wait_selector` to make sure Scrapling waits for the real website content to be loaded after solving the captcha. Some websites can be the real definition of an edge case while we are trying to make the solver as generic as possible.\n2. The timeout should be at least 60 seconds when using the Cloudflare solver for sufficient challenge-solving time.\n3. This feature works seamlessly with proxies and other stealth options.\n\n### Browser Automation\nThis is where your knowledge about [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) comes into play. The function you pass here takes the page object from Playwright's API, performs the desired action, and then the fetcher continues.\n\nThis function is executed immediately after waiting for `network_idle` (if enabled) and before waiting for the `wait_selector` argument, allowing it to be used for purposes beyond automation. You can alter the page as you want.\n\nIn the example below, I used the pages' [mouse events](https://playwright.dev/python/docs/api/class-mouse) to scroll the page with the mouse wheel, then move the mouse.\n```python\nfrom playwright.sync_api import Page\n\ndef scroll_page(page: Page):\n page.mouse.wheel(10, 0)\n page.mouse.move(100, 400)\n page.mouse.up()\n\npage = StealthyFetcher.fetch('https://example.com', page_action=scroll_page)\n```\nOf course, if you use the async fetch version, the function must also be async.\n```python\nfrom playwright.async_api import Page\n\nasync def scroll_page(page: Page):\n await page.mouse.wheel(10, 0)\n await page.mouse.move(100, 400)\n await page.mouse.up()\n\npage = await StealthyFetcher.async_fetch('https://example.com', page_action=scroll_page)\n```\n\n### Wait Conditions\n```python\n# Wait for the selector\npage = StealthyFetcher.fetch(\n 'https://example.com',\n wait_selector='h1',\n wait_selector_state='visible'\n)\n```\nThis is the last wait the fetcher will do before returning the response (if enabled). You pass a CSS selector to the `wait_selector` argument, and the fetcher will wait for the state you passed in the `wait_selector_state` argument to be fulfilled. If you didn't pass a state, the default would be `attached`, which means it will wait for the element to be present in the DOM.\n\nAfter that, if `load_dom` is enabled (the default), the fetcher will check again to see if all JavaScript files are loaded and executed (in the `domcontentloaded` state) or continue waiting. If you have enabled `network_idle`, the fetcher will wait for `network_idle` to be fulfilled again, as explained above.\n\nThe states the fetcher can wait for can be any of the following ([source](https://playwright.dev/python/docs/api/class-page#page-wait-for-selector)):\n\n- `attached`: Wait for an element to be present in the DOM.\n- `detached`: Wait for an element to not be present in the DOM.\n- `visible`: wait for an element to have a non-empty bounding box and no `visibility:hidden`. Note that an element without any content or with `display:none` has an empty bounding box and is not considered visible.\n- `hidden`: wait for an element to be either detached from the DOM, or have an empty bounding box, or `visibility:hidden`. This is opposite to the `'visible'` option.\n\n\n### Real-world example (Amazon)\nThis is for educational purposes only; this example was generated by AI, which also shows how easy it is to work with Scrapling through AI\n```python\ndef scrape_amazon_product(url):\n # Use StealthyFetcher to bypass protection\n page = StealthyFetcher.fetch(url)\n\n # Extract product details\n return {\n 'title': page.css('#productTitle::text').get().clean(),\n 'price': page.css('.a-price .a-offscreen::text').get(),\n 'rating': page.css('[data-feature-name=\"averageCustomerReviews\"] .a-popover-trigger .a-color-base::text').get(),\n 'reviews_count': page.css('#acrCustomerReviewText::text').re_first(r'[\\d,]+'),\n 'features': [\n li.get().clean() for li in page.css('#feature-bullets li span::text')\n ],\n 'availability': page.css('#availability')[0].get_all_text(strip=True),\n 'images': [\n img.attrib['src'] for img in page.css('#altImages img')\n ]\n }\n```\n\n## Session Management\n\nTo keep the browser open until you make multiple requests with the same configuration, use `StealthySession`/`AsyncStealthySession` classes. Those classes can accept all the arguments that the `fetch` function can take, which enables you to specify a config for the entire session.\n\n```python\nfrom scrapling.fetchers import StealthySession\n\n# Create a session with default configuration\nwith StealthySession(\n headless=True,\n real_chrome=True,\n block_webrtc=True,\n solve_cloudflare=True\n) as session:\n # Make multiple requests with the same browser instance\n page1 = session.fetch('https://example1.com')\n page2 = session.fetch('https://example2.com') \n page3 = session.fetch('https://nopecha.com/demo/cloudflare')\n \n # All requests reuse the same tab on the same browser instance\n```\n\n### Async Session Usage\n\n```python\nimport asyncio\nfrom scrapling.fetchers import AsyncStealthySession\n\nasync def scrape_multiple_sites():\n async with AsyncStealthySession(\n real_chrome=True,\n block_webrtc=True,\n solve_cloudflare=True,\n timeout=60000, # 60 seconds for Cloudflare challenges\n max_pages=3\n ) as session:\n # Make async requests with shared browser configuration\n pages = await asyncio.gather(\n session.fetch('https://site1.com'),\n session.fetch('https://site2.com'), \n session.fetch('https://protected-site.com')\n )\n return pages\n```\n\nYou may have noticed the `max_pages` argument. This is a new argument that enables the fetcher to create a **rotating pool of Browser tabs**. Instead of using a single tab for all your requests, you set a limit on the maximum number of pages that can be displayed at once. With each request, the library will close all tabs that have finished their task and check if the number of the current tabs is lower than the maximum allowed number of pages/tabs, then:\n\n1. If you are within the allowed range, the fetcher will create a new tab for you, and then all is as normal.\n2. Otherwise, it will keep checking every subsecond if creating a new tab is allowed or not for 60 seconds, then raise `TimeoutError`. This can happen when the website you are fetching becomes unresponsive.\n\nThis logic allows for multiple URLs to be fetched at the same time in the same browser, which saves a lot of resources, but most importantly, is so fast :)\n\nIn versions 0.3 and 0.3.1, the pool was reusing finished tabs to save more resources/time. That logic proved flawed, as it's nearly impossible to protect pages/tabs from contamination by the previous configuration used in the request before this one.\n\n### Session Benefits\n\n- **Browser reuse**: Much faster subsequent requests by reusing the same browser instance.\n- **Cookie persistence**: Automatic cookie and session state handling as any browser does automatically.\n- **Consistent fingerprint**: Same browser fingerprint across all requests.\n- **Memory efficiency**: Better resource usage compared to launching new browsers with each fetch.\n\n## When to Use\n\nUse StealthyFetcher when:\n\n- Bypassing anti-bot protection\n- Need a reliable browser fingerprint\n- Full JavaScript support needed\n- Want automatic stealth features\n- Need browser automation\n- Dealing with Cloudflare protection" }, { "path": "agent-skill/Scrapling-Skill/references/mcp-server.md", "content": "# Scrapling MCP Server\n\nThe Scrapling MCP server exposes six web scraping tools over the MCP protocol.

Scrapling always uses `lxml` for performance.\n- **Element Types**: BeautifulSoup elements are `Tag` objects; Scrapling elements are `Selector` objects. Both provide similar navigation and extraction methods.\n- **Error Handling**: Both libraries return `None` when an element is not found (e.g., `soup.find()` or `page.find()`). `page.css()` returns an empty `Selectors` list when no elements match. Use `page.css('.foo').first` to safely get the first match or `None`.\n- **Text Extraction**: Scrapling's `TextHandler` provides additional text processing methods such as `clean()` for removing extra whitespace, consecutive spaces, or unwanted characters." }, { "path": "agent-skill/Scrapling-Skill/references/parsing/adaptive.md", "content": "# Adaptive scraping\n\nAdaptive scraping (previously known as automatch) is one of Scrapling's most powerful features.

\n```\nThe selector will no longer function, and your code needs maintenance. That's where Scrapling's `adaptive` feature comes into play.\n\nWith Scrapling, you can enable the `adaptive` feature the first time you select an element, and the next time you select that element and it doesn't exist, Scrapling will remember its properties and search on the website for the element with the highest percentage of similarity to that element.\n\n```python\nfrom scrapling import Selector, Fetcher\n# Before the change\npage = Selector(page_source, adaptive=True, url='example.com')\n# or\nFetcher.adaptive = True\npage = Fetcher.get('https://example.com')\n# then\nelement = page.css('#p1', auto_save=True)\nif not element: # One day website changes?\n element = page.css('#p1', adaptive=True) # Scrapling still finds it!\n# the rest of your code...\n```\nIt works with all selection methods, not just CSS/XPath selection.\n\n## Real-World Scenario\nThis example uses [The Web Archive](https://archive.org/)'s [Wayback Machine](https://web.archive.org/) to demonstrate adaptive scraping across different versions of a website. A copy of [StackOverflow's website in 2010](https://web.archive.org/web/20100102003420/http://stackoverflow.com/) is compared against the current design to show that the adaptive feature can extract the same button using the same selector.\n\nTo extract the Questions button from the old design, a selector like `#hmenus > div:nth-child(1) > ul > li:nth-child(1) > a` can be used (this specific selector was generated by Chrome).\n\nTesting the same selector in both versions:\n```python\n>> from scrapling import Fetcher\n>> selector = '#hmenus > div:nth-child(1) > ul > li:nth-child(1) > a'\n>> old_url = \"https://web.archive.org/web/20100102003420/http://stackoverflow.com/\"\n>> new_url = \"https://stackoverflow.com/\"\n>> Fetcher.configure(adaptive = True, adaptive_domain='stackoverflow.com')\n>> \n>> page = Fetcher.get(old_url, timeout=30)\n>> element1 = page.css(selector, auto_save=True)[0]\n>> \n>> # Same selector but used in the updated website\n>> page = Fetcher.get(new_url)\n>> element2 = page.css(selector, adaptive=True)[0]\n>> \n>> if element1.text == element2.text:\n... print('Scrapling found the same element in the old and new designs!')\n'Scrapling found the same element in the old and new designs!'\n```\nThe `adaptive_domain` argument is used here because Scrapling sees `archive.org` and `stackoverflow.com` as two different domains and would isolate their `adaptive` data. Passing `adaptive_domain` tells Scrapling to treat them as the same website for adaptive data storage.\n\nIn a typical scenario with the same URL for both requests, the `adaptive_domain` argument is not needed. The adaptive logic works the same way with both the `Selector` and `Fetcher` classes.\n\n**Note:** The main reason for creating the `adaptive_domain` argument was to handle if the website changed its URL while changing the design/structure. In that case, it can be used to continue using the previously stored adaptive data for the new URL. Otherwise, Scrapling will consider it a new website and discard the old data.\n\n## How the adaptive scraping feature works\nAdaptive scraping works in two phases:\n\n1. **Save Phase**: Store unique properties of elements\n2. **Match Phase**: Find elements with similar properties later\n\nAfter selecting an element through any method, the library can find it the next time the website is scraped, even if it undergoes structural/design changes.\n\nThe general logic is as follows:\n\n 1. Scrapling saves that element's unique properties (methods shown below).\n 2. Scrapling uses its configured database (SQLite by default) and saves each element's unique properties.\n 3. Because everything about the element can be changed or removed by the website's owner(s), nothing from the element can be used as a unique identifier for the database. The storage system relies on two things:\n 1. The domain of the current website. When using the `Selector` class, pass it when initializing; when using a fetcher, the domain is automatically taken from the URL.\n 2. An `identifier` to query that element's properties from the database. The identifier does not always need to be set manually (see below).\n\n Together, they will later be used to retrieve the element's unique properties from the database.\n\n 4. Later, when the website's structure changes, enabling `adaptive` causes Scrapling to retrieve the element's unique properties and match all elements on the page against them. A score is calculated based on their similarity to the desired element. Everything is taken into consideration in that comparison.\n 5. The element(s) with the highest similarity score to the wanted element are returned.\n\n### The unique properties\nThe unique properties Scrapling relies on are:\n\n- Element tag name, text, attributes (names and values), siblings (tag names only), and path (tag names only).\n- Element's parent tag name, attributes (names and values), and text.\n\nThe comparison between elements is not exact; it is based on how similar these values are. Everything is considered, including the values' order (e.g., the order in which class names are written).\n\n## How to use adaptive feature\nThe adaptive feature can be applied to any found element and is added as arguments to CSS/XPath selection methods.\n\nFirst, enable the `adaptive` feature by passing `adaptive=True` to the [Selector](main_classes.md#selector) class when initializing it, or enable it on the fetcher being used.\n\nExamples:\n```python\n>>> from scrapling import Selector, Fetcher\n>>> page = Selector(html_doc, adaptive=True)\n# OR\n>>> Fetcher.adaptive = True\n>>> page = Fetcher.get('https://example.com')\n```\nWhen using the [Selector](main_classes.md#selector) class, pass the URL of the website with the `url` argument so Scrapling can separate the properties saved for each element by domain.\n\nIf no URL is passed, the word `default` will be used in place of the URL field while saving the element's unique properties. This is only an issue when using the same identifier for a different website without passing the URL parameter. The save process overwrites previous data, and the `adaptive` feature uses only the latest saved properties.\n\nThe `storage` and `storage_args` arguments control the database connection; by default, the SQLite class provided by the library is used.\n\nThere are two main ways to use the `adaptive` feature:\n\n### The CSS/XPath Selection way\nFirst, use the `auto_save` argument while selecting an element that exists on the page:\n```python\nelement = page.css('#p1', auto_save=True)\n```\nWhen the element no longer exists, use the same selector with the `adaptive` argument to have the library find it:\n```python\nelement = page.css('#p1', adaptive=True)\n```\nWith the `css`/`xpath` methods, the identifier is set automatically to the selector string passed to the method.\n\nAdditionally, for all these methods, you can pass the `identifier` argument to set it yourself. This is useful in some instances, or you can use it to save properties with the `auto_save` argument.\n\n### The manual way\nElements can be manually saved, retrieved, and relocated within the `adaptive` feature. This allows relocating any element found by any method.\n\nExample of getting an element by text:\n```python\n>>> element = page.find_by_text('Tipping the Velvet', first_match=True)\n```\nSave its unique properties using the `save` method. The identifier must be set manually (use a meaningful identifier):\n```python\n>>> page.save(element, 'my_special_element')\n```\nLater, retrieve and relocate the element inside the page with `adaptive`:\n```python\n>>> element_dict = page.retrieve('my_special_element')\n>>> page.relocate(element_dict, selector_type=True)\n[]\n>>> page.relocate(element_dict, selector_type=True).css('::text').getall()\n['Tipping the Velvet']\n```\nThe `retrieve` and `relocate` methods are used here.\n\nTo keep it as a `lxml.etree` object, omit the `selector_type` argument:\n```python\n>>> page.relocate(element_dict)\n[]\n```\n\n## Troubleshooting\n\n### No Matches Found\n```python\n# 1. Check if data was saved\nelement_data = page.retrieve('identifier')\nif not element_data:\n print(\"No data saved for this identifier\")\n\n# 2. Try with different identifier\nproducts = page.css('.product', adaptive=True, identifier='old_selector')\n\n# 3. Save again with new identifier\nproducts = page.css('.new-product', auto_save=True, identifier='new_identifier')\n```\n\n### Wrong Elements Matched\n```python\n# Use more specific selectors\nproducts = page.css('.product-list .product', auto_save=True)\n\n# Or save with more context\nproduct = page.find_by_text('Product Name').parent\npage.save(product, 'specific_product')\n```\n\n## Known Issues\nIn the `adaptive` save process, only the unique properties of the first element in the selection results are saved. So if the selector you are using selects different elements on the page in other locations, `adaptive` will return the first element to you only when you relocate it later. This doesn't include combined CSS selectors (Using commas to combine more than one selector, for example), as these selectors are separated and each is executed alone.\n\n" }, { "path": "agent-skill/Scrapling-Skill/references/parsing/main_classes.md", "content": "# Parsing main classes\n\nThe [Selector](#selector) class is the core parsing engine in Scrapling, providing HTML parsing and element selection capabilities. You can always import it with any of the following imports\n```python\nfrom scrapling import Selector\nfrom scrapling.parser import Selector\n```\nUsage:\n```python\npage = Selector(\n '...',\n url='https://example.com'\n)\n\n# Then select elements as you like\nelements = page.css('.product')\n```\nIn Scrapling, the main object you deal with after passing an HTML source or fetching a website is, of course, a [Selector](#selector) object. Any operation you do, like selection, navigation, etc., will return either a [Selector](#selector) object or a [Selectors](#selectors) object, given that the result is element/elements from the page, not text or similar.\n\nThe main page is a [Selector](#selector) object, and the elements within are [Selector](#selector) objects. Any text (text content inside elements or attribute values) is a [TextHandler](#texthandler) object, and element attributes are stored as [AttributesHandler](#attributeshandler).\n\n## Selector\n### Arguments explained\nThe most important one is `content`, it's used to pass the HTML code you want to parse, and it accepts the HTML content as `str` or `bytes`.\n\nThe arguments `url`, `adaptive`, `storage`, and `storage_args` are settings used with the `adaptive` feature. They are explained in the [adaptive](adaptive.md) feature page.\n\nArguments for parsing adjustments:\n\n- **encoding**: This is the encoding that will be used while parsing the HTML. The default is `UTF-8`.\n- **keep_comments**: This tells the library whether to keep HTML comments while parsing the page. It's disabled by default because it can cause issues with your scraping in various ways.\n- **keep_cdata**: Same logic as the HTML comments. [cdata](https://stackoverflow.com/questions/7092236/what-is-cdata-in-html) is removed by default for cleaner HTML.\n\nThe arguments `huge_tree` and `root` are advanced features not covered here.\n\nMost properties on the main page and its elements are lazily loaded (not initialized until accessed), which contributes to Scrapling's speed.\n\n### Properties\nProperties for traversal are separated in the [traversal](#traversal) section below.\n\nParsing this HTML page as an example:\n```html\n\n \n Some page\n \n \n

The default is '\\n'.\n2. **strip**: If enabled, strings will be stripped before concatenation. Disabled by default.\n3. **ignore_tags**: A tuple of all tag names you want to ignore in the final results and ignore any elements nested within them. The default is `('script', 'style',)`.\n4. **valid_values**: If enabled, the method will only collect elements with real values, so all elements with empty text content or only whitespaces will be ignored. It's enabled by default\n\nThe text returned is a [TextHandler](#texthandler), not a standard string. If the text content can be serialized to JSON, use `.json()` on it:\n```python\n>>> script = page.find('script')\n>>> script.json()\n{'lastUpdated': '2024-09-22T10:30:00Z', 'totalProducts': 3}\n```\nLet's continue to get the element tag\n```python\n>>> article.tag\n'article'\n```\nUsing it on the page directly operates on the root `html` element:\n```python\n>>> page.tag\n'html'\n```\nGetting the attributes of the element\n```python\n>>> print(article.attrib)\n{'class': 'product', 'data-id': '1'}\n```\nAccess a specific attribute with any of the following\n```python\n>>> article.attrib['class']\n>>> article.attrib.get('class')\n>>> article['class'] # new in v0.3\n```\nCheck if the attributes contain a specific attribute with any of the methods below\n```python\n>>> 'class' in article.attrib\n>>> 'class' in article # new in v0.3\n```\nGet the HTML content of the element\n```python\n>>> article.html_content\n'

\n```\nUse the `.body` property to get the raw content of the page. Starting from v0.4, when used on a `Response` object from fetchers, `.body` always returns `bytes`.\n```python\n>>> page.body\n'\\n \\n Some page\\n \\n ...'\n```\nTo get all the ancestors in the DOM tree of this element\n```python\n>>> article.path\n[
,\n
,\n Some page]\n```\nGenerate a CSS shortened selector if possible, or generate the full selector\n```python\n>>> article.generate_css_selector\n'body > div > article'\n>>> article.generate_full_css_selector\n'body > div > article'\n```\nSame case with XPath\n```python\n>>> article.generate_xpath_selector\n\"//body/div/article\"\n>>> article.generate_full_xpath_selector\n\"//body/div/article\"\n```\n\n### Traversal\nProperties and methods for navigating elements on the page.\n\nThe `html` element is the root of the website's tree. Elements like `head` and `body` are \"children\" of `html`, and `html` is their \"parent\". The element `body` is a \"sibling\" of `head` and vice versa.\n\nAccessing the parent of an element\n```python\n>>> article.parent\n
\n>>> article.parent.tag\n'div'\n```\nChaining is supported, as with all similar properties/methods:\n```python\n>>> article.parent.parent.tag\n'body'\n```\nGet the children of an element\n```python\n>>> article.children\n[Product 1' parent='
,\n This is product 1...' parent='
,\n $10.99' parent='
,\n In stock: 5]\n```\nGet all elements underneath an element. It acts as a nested version of the `children` property\n```python\n>>> article.below_elements\n[Product 1' parent='
,\n This is product 1...' parent='
,\n $10.99' parent='
,\n In stock: 5]\n```\nThis element returns the same result as the `children` property because its children don't have children.\n\nAnother example of using the element with the `product-list` class will clear the difference between the `children` property and the `below_elements` property\n```python\n>>> products_list = page.css('.product-list')[0]\n>>> products_list.children\n[,\n ,\n ]\n\n>>> products_list.below_elements\n[,\n Product 1' parent='
,\n This is product 1...' parent='
,\n $10.99' parent='
,\n In stock: 5,\n ,\n...]\n```\nGet the siblings of an element\n```python\n>>> article.siblings\n[,\n ]\n```\nGet the next element of the current element\n```python\n>>> article.next\n\n```\nThe same logic applies to the `previous` property\n```python\n>>> article.previous # It's the first child, so it doesn't have a previous element\n>>> second_article = page.css('.product[data-id=\"2\"]')[0]\n>>> second_article.previous\n\n```\nCheck if an element has a specific class name:\n```python\n>>> article.has_class('product')\nTrue\n```\nIterate over the entire ancestors' tree of any element:\n```python\nfor ancestor in article.iterancestors():\n # do something with it...\n```\nSearch for a specific ancestor that satisfies a search function. Pass a function that takes a [Selector](#selector) object as an argument and returns `True`/`False`:\n```python\n>>> article.find_ancestor(lambda ancestor: ancestor.has_class('product-list'))\n
\n\n>>> article.find_ancestor(lambda ancestor: ancestor.css('.product-list')) # Same result, different approach\n
\n```\n## Selectors\nThe class `Selectors` is the \"List\" version of the [Selector](#selector) class. It inherits from the Python standard `List` type, so it shares all `List` properties and methods while adding more methods to make the operations you want to execute on the [Selector](#selector) instances within more straightforward.\n\nIn the [Selector](#selector) class, all methods/properties that should return a group of elements return them as a [Selectors](#selectors) class instance.\n\nStarting with v0.4, all selection methods consistently return [Selector](#selector)/[Selectors](#selectors) objects, even for text nodes and attribute values. Text nodes (selected via `::text`, `/text()`, `::attr()`, `/@attr`) are wrapped in [Selector](#selector) objects. These text node selectors have `tag` set to `\"#text\"`, and their `text` property returns the text value. You can still access the text value directly, and all other properties return empty/default values gracefully.\n\n```python\n>>> page.css('a::text') # -> Selectors (of text node Selectors)\n>>> page.xpath('//a/text()') # -> Selectors\n>>> page.css('a::text').get() # -> TextHandler (the first text value)\n>>> page.css('a::text').getall() # -> TextHandlers (all text values)\n>>> page.css('a::attr(href)') # -> Selectors\n>>> page.xpath('//a/@href') # -> Selectors\n>>> page.css('.price_color') # -> Selectors\n```\n\n### Data extraction methods\nStarting with v0.4, [Selector](#selector) and [Selectors](#selectors) both provide `get()`, `getall()`, and their aliases `extract_first` and `extract` (following Scrapy conventions). The old `get_all()` method has been removed.\n\n**On a [Selector](#selector) object:**\n\n- `get()` returns a `TextHandler` โ€” for text node selectors, it returns the text value; for HTML element selectors, it returns the serialized outer HTML.\n- `getall()` returns a `TextHandlers` list containing the single serialized string.\n- `extract_first` is an alias for `get()`, and `extract` is an alias for `getall()`.\n\n```python\n>>> page.css('h3')[0].get() # Outer HTML of the element\n'

Product 1

'\n\n>>> page.css('h3::text')[0].get() # Text value of the text node\n'Product 1'\n```\n\n**On a [Selectors](#selectors) object:**\n\n- `get(default=None)` returns the serialized string of the **first** element, or `default` if the list is empty.\n- `getall()` serializes **all** elements and returns a `TextHandlers` list.\n- `extract_first` is an alias for `get()`, and `extract` is an alias for `getall()`.\n\n```python\n>>> page.css('.price::text').get() # First price text\n'$10.99'\n\n>>> page.css('.price::text').getall() # All price texts\n['$10.99', '$20.99', '$15.99']\n\n>>> page.css('.price::text').get('') # With default value\n'$10.99'\n```\n\nThese methods work seamlessly with all selection types (CSS, XPath, `find`, etc.) and are the recommended way to extract text and attribute values in a Scrapy-compatible style.\n\n### Properties\nApart from the standard operations on Python lists (iteration, slicing, etc.), the following operations are available:\n\nCSS and XPath selectors can be executed directly on the [Selector](#selector) instances, with the same return types as [Selector](#selector)'s `css` and `xpath` methods. The arguments are similar, except the `adaptive` argument is not available. This makes chaining methods straightforward:\n```python\n>>> page.css('.product_pod a')\n[,\n ,\n ,\n ,\n ,\n ,\n...]\n\n>>> page.css('.product_pod').css('a') # Returns the same result\n[,\n ,\n ,\n ,\n ,\n ,\n...]\n```\nThe `re` and `re_first` methods can be run directly. They take the same arguments as the [Selector](#selector) class. In this class, `re_first` runs `re` on each [Selector](#selector) within and returns the first one with a result. The `re` method returns a [TextHandlers](#texthandlers) object combining all matches:\n```python\n>>> page.css('.price_color').re(r'[\\d\\.]+')\n['51.77',\n '53.74',\n '50.10',\n '47.82',\n '54.23',\n...]\n\n>>> page.css('.product_pod h3 a::attr(href)').re(r'catalogue/(.*)/index.html')\n['a-light-in-the-attic_1000',\n 'tipping-the-velvet_999',\n 'soumission_998',\n 'sharp-objects_997',\n...]\n```\nThe `search` method searches the available [Selector](#selector) instances. The function passed must accept a [Selector](#selector) instance as the first argument and return True/False. Returns the first matching [Selector](#selector) instance, or `None`:\n```python\n# Find all the products with price '53.23'.\n>>> search_function = lambda p: float(p.css('.price_color').re_first(r'[\\d\\.]+')) == 54.23\n>>> page.css('.product_pod').search(search_function)\n
\n```\nThe `filter` method takes a function like `search` but returns a `Selectors` instance of all matching [Selector](#selector) instances:\n```python\n# Find all products with prices over $50\n>>> filtering_function = lambda p: float(p.css('.price_color').re_first(r'[\\d\\.]+')) > 50\n>>> page.css('.product_pod').filter(filtering_function)\n[
,\n
,\n
,\n...]\n```\nSafe access to the first or last element without index errors:\n```python\n>>> page.css('.product').first # First Selector or None\n\n>>> page.css('.product').last # Last Selector or None\n\n>>> page.css('.nonexistent').first # Returns None instead of raising IndexError\n```\n\nGet the number of [Selector](#selector) instances in a [Selectors](#selectors) instance:\n```python\npage.css('.product_pod').length\n```\nwhich is equivalent to\n```python\nlen(page.css('.product_pod'))\n```\n\n## TextHandler\nAll methods/properties that return a string return `TextHandler`, and those that return a list of strings return [TextHandlers](#texthandlers) instead.\n\nTextHandler is a subclass of the standard Python string, so all standard string operations are supported.\n\nTextHandler provides extra methods and properties beyond standard Python strings. All methods and properties in all classes that return string(s) return TextHandler, enabling chaining and cleaner code. It can also be imported directly and used on any string.\n### Usage\nAll operations (slicing, indexing, etc.) and methods (`split`, `replace`, `strip`, etc.) return a `TextHandler`, so they can be chained.\n\nThe `re` and `re_first` methods exist in [Selector](#selector), [Selectors](#selectors), and [TextHandlers](#texthandlers) as well, accepting the same arguments.\n\n- The `re` method takes a string/compiled regex pattern as the first argument. It searches the data for all strings matching the regex and returns them as a [TextHandlers](#texthandlers) instance. The `re_first` method takes the same arguments but returns only the first result as a `TextHandler` instance.\n \n Also, it takes other helpful arguments, which are:\n \n - **replace_entities**: This is enabled by default. It replaces character entity references with their corresponding characters.\n - **clean_match**: It's disabled by default. This causes the method to ignore all whitespace, including consecutive spaces, while matching.\n - **case_sensitive**: It's enabled by default. As the name implies, disabling it causes the regex to ignore letter case during compilation.\n \n The return result is [TextHandlers](#texthandlers) because the `re` method is used:\n ```python\n >>> page.css('.price_color').re(r'[\\d\\.]+')\n ['51.77',\n '53.74',\n '50.10',\n '47.82',\n '54.23',\n ...]\n \n >>> page.css('.product_pod h3 a::attr(href)').re(r'catalogue/(.*)/index.html')\n ['a-light-in-the-attic_1000',\n 'tipping-the-velvet_999',\n 'soumission_998',\n 'sharp-objects_997',\n ...]\n ```\n Examples with custom strings demonstrating the other arguments:\n ```python\n >>> from scrapling import TextHandler\n >>> test_string = TextHandler('hi there') # Hence the two spaces\n >>> test_string.re('hi there')\n >>> test_string.re('hi there', clean_match=True) # Using `clean_match` will clean the string before matching the regex\n ['hi there']\n \n >>> test_string2 = TextHandler('Oh, Hi Mark')\n >>> test_string2.re_first('oh, hi Mark')\n >>> test_string2.re_first('oh, hi Mark', case_sensitive=False) # Hence disabling `case_sensitive`\n 'Oh, Hi Mark'\n \n # Mixing arguments\n >>> test_string.re('hi there', clean_match=True, case_sensitive=False)\n ['hi There']\n ```\n Since `html_content` returns `TextHandler`, regex can be applied directly on HTML content:\n ```python\n >>> page.html_content.re('div class=\".*\">(.*)>> page.css('#page-data::text').get()\n '\\n {\\n \"lastUpdated\": \"2024-09-22T10:30:00Z\",\\n \"totalProducts\": 3\\n }\\n '\n >>> page.css('#page-data::text').get().json()\n {'lastUpdated': '2024-09-22T10:30:00Z', 'totalProducts': 3}\n ```\n If no text node is specified while selecting an element, the text content is selected automatically:\n ```python\n >>> page.css('#page-data')[0].json()\n {'lastUpdated': '2024-09-22T10:30:00Z', 'totalProducts': 3}\n ```\n The [Selector](#selector) class adds additional behavior. Given this page:\n ```html\n \n \n
\n \n
\n \n \n ```\n The [Selector](#selector) class has the `get_all_text` method, which returns a `TextHandler`. For example:\n ```python\n >>> page.css('div::text').get().json()\n ```\n This throws an error because the `div` tag has no direct text content. The `get_all_text` method handles this case:\n ```python\n >>> page.css('div')[0].get_all_text(ignore_tags=[]).json()\n {'lastUpdated': '2024-09-22T10:30:00Z', 'totalProducts': 3}\n ```\n The `ignore_tags` argument is used here because its default value is `('script', 'style',)`.\n\n When dealing with a JSON response:\n ```python\n >>> page = Selector(\"\"\"{\"some_key\": \"some_value\"}\"\"\")\n ```\n The [Selector](#selector) class is optimized for HTML, so it treats this as a broken HTML response and wraps it. The `html_content` property shows:\n ```python\n >>> page.html_content\n '

{\"some_key\": \"some_value\"}

'\n ```\n The `json` method can be used directly:\n ```python\n >>> page.json()\n {'some_key': 'some_value'}\n ```\n For JSON responses, the [Selector](#selector) class keeps a raw copy of the content it receives. When `.json()` is called, it checks for that raw copy first and converts it to JSON. If the raw copy is unavailable (as with sub-elements), it checks the current element's text content, then falls back to `get_all_text`.\n\n- The `.clean()` method removes all whitespace and consecutive spaces, returning a new `TextHandler` instance:\n```python\n>>> TextHandler('\\n wonderful idea, \\reh?').clean()\n'wonderful idea, eh?'\n```\nThe `remove_entities` argument causes `clean` to replace HTML entities with their corresponding characters.\n\n- The `.sort()` method sorts the string characters:\n```python\n>>> TextHandler('acb').sort()\n'abc'\n```\nOr do it in reverse:\n```python\n>>> TextHandler('acb').sort(reverse=True)\n'cba'\n```\n\nThis class is returned in place of strings nearly everywhere in the library.\n\n## TextHandlers\nThis class inherits from standard lists, adding `re` and `re_first` as new methods.\n\nThe `re_first` method runs `re` on each [TextHandler](#texthandler) and returns the first result, or `None`.\n\n## AttributesHandler\nThis is a read-only version of Python's standard dictionary, or `dict`, used solely to store the attributes of each element/[Selector](#selector) instance.\n```python\n>>> print(page.find('script').attrib)\n{'id': 'page-data', 'type': 'application/json'}\n>>> type(page.find('script').attrib).__name__\n'AttributesHandler'\n```\nBecause it's read-only, it will use fewer resources than the standard dictionary. Still, it has the same dictionary method and properties, except those that allow you to modify/override the data.\n\nIt currently adds two extra simple methods:\n\n- The `search_values` method\n\n Searches the current attributes by values (rather than keys) and returns a dictionary of each matching item.\n \n A simple example would be\n ```python\n >>> for i in page.find('script').attrib.search_values('page-data'):\n print(i)\n {'id': 'page-data'}\n ```\n But this method provides the `partial` argument as well, which allows you to search by part of the value:\n ```python\n >>> for i in page.find('script').attrib.search_values('page', partial=True):\n print(i)\n {'id': 'page-data'}\n ```\n A more practical example is using it with `find_all` to find all elements that have a specific value in their attributes:\n ```python\n >>> page.find_all(lambda element: list(element.attrib.search_values('product')))\n [,\n ,\n ]\n ```\n All these elements have 'product' as the value for the `class` attribute.\n \n The `list` function is used here because `search_values` returns a generator, so it would be `True` for all elements.\n\n- The `json_string` property\n\n This property converts current attributes to a JSON string if the attributes are JSON serializable; otherwise, it throws an error.\n \n ```python\n >>>page.find('script').attrib.json_string\n b'{\"id\":\"page-data\",\"type\":\"application/json\"}'\n ```" }, { "path": "agent-skill/Scrapling-Skill/references/parsing/selection.md", "content": "# Querying elements\nScrapling currently supports parsing HTML pages exclusively (no XML feeds), because the adaptive feature does not work with XML.\n\nIn Scrapling, there are five main ways to find elements:\n\n1. CSS3 Selectors\n2. XPath Selectors\n3. Finding elements based on filters/conditions.\n4. Finding elements whose content contains a specific text\n5. Finding elements whose content matches a specific regex\n\nThere are also other indirect ways to find elements. Scrapling can also find elements similar to a given element; see [Finding Similar Elements](#finding-similar-elements).\n\n## CSS/XPath selectors\n\n### What are CSS selectors?\n[CSS](https://en.wikipedia.org/wiki/CSS) is a language for applying styles to HTML documents. It defines selectors to associate those styles with specific HTML elements.\n\nScrapling implements CSS3 selectors as described in the [W3C specification](http://www.w3.org/TR/2011/REC-css3-selectors-20110929/). CSS selectors support comes from `cssselect`, so it's better to read about which [selectors are supported from cssselect](https://cssselect.readthedocs.io/en/latest/#supported-selectors) and pseudo-functions/elements.\n\nAlso, Scrapling implements some non-standard pseudo-elements like:\n\n* To select text nodes, use ``::text``.\n* To select attribute values, use ``::attr(name)`` where name is the name of the attribute that you want the value of\n\nThe selector logic follows the same conventions as Scrapy/Parsel.\n\nTo select elements with CSS selectors, use the `css` method, which returns `Selectors`. Use `[0]` to get the first element, or `.get()` / `.getall()` to extract text values from text/attribute pseudo-selectors.\n\n### What are XPath selectors?\n[XPath](https://en.wikipedia.org/wiki/XPath) is a language for selecting nodes in XML documents, which can also be used with HTML. This [cheatsheet](https://devhints.io/xpath) is a good resource for learning about [XPath](https://en.wikipedia.org/wiki/XPath). Scrapling adds XPath selectors directly through [lxml](https://lxml.de/).\n\nThe logic follows the same conventions as Scrapy/Parsel. However, Scrapling does not implement the XPath extension function `has-class` as Scrapy/Parsel does. Instead, it provides the `has_class` method on returned elements.\n\nTo select elements with XPath selectors, use the `xpath` method, which follows the same logic as the CSS selectors method above.\n\n> Note that each method of `css` and `xpath` has additional arguments, but we didn't explain them here, as they are all about the adaptive feature. The adaptive feature will have its own page later to be described in detail.\n\n### Selectors examples\nLet's see some shared examples of using CSS and XPath Selectors.\n\nSelect all elements with the class `product`.\n```python\nproducts = page.css('.product')\nproducts = page.xpath('//*[@class=\"product\"]')\n```\n**Note:** The XPath version won't be accurate if there's another class; it's always better to rely on CSS for selecting by class.\n\nSelect the first element with the class `product`.\n```python\nproduct = page.css('.product')[0]\nproduct = page.xpath('//*[@class=\"product\"]')[0]\n```\nGet the text of the first element with the `h1` tag name\n```python\ntitle = page.css('h1::text').get()\ntitle = page.xpath('//h1//text()').get()\n```\nWhich is the same as doing\n```python\ntitle = page.css('h1')[0].text\ntitle = page.xpath('//h1')[0].text\n```\nGet the `href` attribute of the first element with the `a` tag name\n```python\nlink = page.css('a::attr(href)').get()\nlink = page.xpath('//a/@href').get()\n```\nSelect the text of the first element with the `h1` tag name, which contains `Phone`, and under an element with class `product`.\n```python\ntitle = page.css('.product h1:contains(\"Phone\")::text').get()\ntitle = page.xpath('//*[@class=\"product\"]//h1[contains(text(),\"Phone\")]/text()').get()\n```\nYou can nest and chain selectors as you want, given that they return results\n```python\npage.css('.product')[0].css('h1:contains(\"Phone\")::text').get()\npage.xpath('//*[@class=\"product\"]')[0].xpath('//h1[contains(text(),\"Phone\")]/text()').get()\npage.xpath('//*[@class=\"product\"]')[0].css('h1:contains(\"Phone\")::text').get()\n```\nAnother example\n\nAll links that have 'image' in their 'href' attribute\n```python\nlinks = page.css('a[href*=\"image\"]')\nlinks = page.xpath('//a[contains(@href, \"image\")]')\nfor index, link in enumerate(links):\n link_value = link.attrib['href'] # Cleaner than link.css('::attr(href)').get()\n link_text = link.text\n print(f'Link number {index} points to this url {link_value} with text content as \"{link_text}\"')\n```\n\n## Text-content selection\nScrapling provides two ways to select elements based on their direct text content:\n\n1. Elements whose direct text content contains the given text with many options through the `find_by_text` method.\n2. Elements whose direct text content matches the given regex pattern with many options through the `find_by_regex` method.\n\nAnything achievable with `find_by_text` can also be done with `find_by_regex`, but both are provided for convenience.\n\nWith `find_by_text`, you pass the text as the first argument; with `find_by_regex`, the regex pattern is the first argument. Both methods share the following arguments:\n\n* **first_match**: If `True` (the default), the method used will return the first result it finds.\n* **case_sensitive**: If `True`, the case of the letters will be considered.\n* **clean_match**: If `True`, all whitespaces and consecutive spaces will be replaced with a single space before matching.\n\nBy default, Scrapling searches for the exact matching of the text/pattern you pass to `find_by_text`, so the text content of the wanted element has to be ONLY the text you input, but that's why it also has one extra argument, which is:\n\n* **partial**: If enabled, `find_by_text` will return elements that contain the input text. So it's not an exact match anymore\n\n**Note:** The method `find_by_regex` can accept both regular strings and a compiled regex pattern as its first argument.\n\n### Finding Similar Elements\nScrapling can find elements similar to a given element, inspired by the AutoScraper library but usable with elements found by any method.\n\nGiven an element (e.g., a product found by title), calling `.find_similar()` on it causes Scrapling to:\n\n1. Find all page elements with the same DOM tree depth as this element. \n2. All found elements will be checked, and those without the same tag name, parent tag name, and grandparent tag name will be dropped.\n3. As a final check, Scrapling uses fuzzy matching to drop elements whose attributes don't resemble the original element's attributes. A configurable percentage controls this step (see arguments below).\n\nArguments for `find_similar()`:\n\n* **similarity_threshold**: The percentage for comparing elements' attributes (step 3). Default is 0.2 (tag attributes must be at least 20% similar). Set to 0 to disable this check entirely.\n* **ignore_attributes**: The attribute names passed will be ignored while matching the attributes in the last step. The default value is `('href', 'src',)` because URLs can change significantly across elements, making them unreliable.\n* **match_text**: If `True`, the element's text content will be considered when matching (Step 3). Using this argument in typical cases is not recommended, but it depends.\n\n### Examples\nExamples of finding elements with raw text, regex, and `find_similar`.\n```python\nfrom scrapling.fetchers import Fetcher\npage = Fetcher.get('https://books.toscrape.com/index.html')\n```\nFind the first element whose text fully matches this text\n```python\n>>> page.find_by_text('Tipping the Velvet')\n\n```\nCombining it with `page.urljoin` to return the full URL from the relative `href`.\n```python\n>>> page.find_by_text('Tipping the Velvet').attrib['href']\n'catalogue/tipping-the-velvet_999/index.html'\n>>> page.urljoin(page.find_by_text('Tipping the Velvet').attrib['href'])\n'https://books.toscrape.com/catalogue/tipping-the-velvet_999/index.html'\n```\nGet all matches if there are more (notice it returns a list)\n```python\n>>> page.find_by_text('Tipping the Velvet', first_match=False)\n[]\n```\nGet all elements that contain the word `the` (Partial matching)\n```python\n>>> results = page.find_by_text('the', partial=True, first_match=False)\n>>> [i.text for i in results]\n['A Light in the ...',\n 'Tipping the Velvet',\n 'The Requiem Red',\n 'The Dirty Little Secrets ...',\n 'The Coming Woman: A ...',\n 'The Boys in the ...',\n 'The Black Maria',\n 'Mesaerion: The Best Science ...',\n \"It's Only the Himalayas\"]\n```\nThe search is case-insensitive by default, so those results include `The`, not just the lowercase `the`. To limit to exact case:\n```python\n>>> results = page.find_by_text('the', partial=True, first_match=False, case_sensitive=True)\n>>> [i.text for i in results]\n['A Light in the ...',\n 'Tipping the Velvet',\n 'The Boys in the ...',\n \"It's Only the Himalayas\"]\n```\nGet the first element whose text content matches my price regex\n```python\n>>> page.find_by_regex(r'ยฃ[\\d\\.]+')\nยฃ51.77

' parent='

\n>>> page.find_by_regex(r'ยฃ[\\d\\.]+').text\n'ยฃ51.77'\n```\nIt's the same if you pass the compiled regex as well; Scrapling will detect the input type and act upon that:\n```python\n>>> import re\n>>> regex = re.compile(r'ยฃ[\\d\\.]+')\n>>> page.find_by_regex(regex)\nยฃ51.77

' parent='

\n>>> page.find_by_regex(regex).text\n'ยฃ51.77'\n```\nGet all elements that match the regex\n```python\n>>> page.find_by_regex(r'ยฃ[\\d\\.]+', first_match=False)\n[ยฃ51.77

' parent='

,\n ยฃ53.74

' parent='

,\n ยฃ50.10

' parent='

,\n ยฃ47.82

' parent='

,\n ...]\n```\nAnd so on...\n\nFind all elements similar to the current element in location and attributes. For our case, ignore the 'title' attribute while matching\n```python\n>>> element = page.find_by_text('Tipping the Velvet')\n>>> element.find_similar(ignore_attributes=['title'])\n[,\n ,\n ,\n...]\n```\nThe number of elements is 19, not 20, because the current element is not included in the results:\n```python\n>>> len(element.find_similar(ignore_attributes=['title']))\n19\n```\nGet the `href` attribute from all similar elements\n```python\n>>> [\n element.attrib['href']\n for element in element.find_similar(ignore_attributes=['title'])\n]\n['catalogue/a-light-in-the-attic_1000/index.html',\n 'catalogue/soumission_998/index.html',\n 'catalogue/sharp-objects_997/index.html',\n ...]\n```\nGetting all books' data using that element as a starting point:\n```python\n>>> for product in element.parent.parent.find_similar():\n print({\n \"name\": product.css('h3 a::text').get(),\n \"price\": product.css('.price_color')[0].re_first(r'[\\d\\.]+'),\n \"stock\": product.css('.availability::text').getall()[-1].clean()\n })\n{'name': 'A Light in the ...', 'price': '51.77', 'stock': 'In stock'}\n{'name': 'Soumission', 'price': '50.10', 'stock': 'In stock'}\n{'name': 'Sharp Objects', 'price': '47.82', 'stock': 'In stock'}\n...\n```\n### Advanced examples\nAdvanced examples using the `find_similar` method:\n\nE-commerce Product Extraction\n```python\ndef extract_product_grid(page):\n # Find the first product card\n first_product = page.find_by_text('Add to Cart').find_ancestor(\n lambda e: e.has_class('product-card')\n )\n\n # Find similar product cards\n products = first_product.find_similar()\n\n return [\n {\n 'name': p.css('h3::text').get(),\n 'price': p.css('.price::text').re_first(r'\\d+\\.\\d{2}'),\n 'stock': 'In stock' in p.text,\n 'rating': p.css('.rating')[0].attrib.get('data-rating')\n }\n for p in products\n ]\n```\nTable Row Extraction\n```python\ndef extract_table_data(page):\n # Find the first data row\n first_row = page.css('table tbody tr')[0]\n\n # Find similar rows\n rows = first_row.find_similar()\n\n return [\n {\n 'column1': row.css('td:nth-child(1)::text').get(),\n 'column2': row.css('td:nth-child(2)::text').get(),\n 'column3': row.css('td:nth-child(3)::text').get()\n }\n for row in rows\n ]\n```\nForm Field Extraction\n```python\ndef extract_form_fields(page):\n # Find first form field container\n first_field = page.css('input')[0].find_ancestor(\n lambda e: e.has_class('form-field')\n )\n\n # Find similar field containers\n fields = first_field.find_similar()\n\n return [\n {\n 'label': f.css('label::text').get(),\n 'type': f.css('input')[0].attrib.get('type'),\n 'required': 'required' in f.css('input')[0].attrib\n }\n for f in fields\n ]\n```\nExtracting reviews from a website\n```python\ndef extract_reviews(page):\n # Find first review\n first_review = page.find_by_text('Great product!')\n review_container = first_review.find_ancestor(\n lambda e: e.has_class('review')\n )\n \n # Find similar reviews\n all_reviews = review_container.find_similar()\n \n return [\n {\n 'text': r.css('.review-text::text').get(),\n 'rating': r.attrib.get('data-rating'),\n 'author': r.css('.reviewer::text').get()\n }\n for r in all_reviews\n ]\n```\n## Filters-based searching\nInspired by BeautifulSoup's `find_all` function, elements can be found using the `find_all` and `find` methods. Both methods accept multiple filters and return all elements on the pages where all filters apply.\n\nTo be more specific:\n\n* Any string passed is considered a tag name.\n* Any iterable passed, like List/Tuple/Set, will be considered as an iterable of tag names.\n* Any dictionary is considered a mapping of HTML element(s), attribute names, and attribute values.\n* Any regex patterns passed are used to filter elements by content, like the `find_by_regex` method\n* Any functions passed are used to filter elements\n* Any keyword argument passed is considered as an HTML element attribute with its value.\n\nIt collects all passed arguments and keywords, and each filter passes its results to the following filter in a waterfall-like filtering system.\n\nIt filters all elements in the current page/element in the following order:\n\n1. All elements with the passed tag name(s) get collected.\n2. All elements that match all passed attribute(s) are collected; if a previous filter is used, then previously collected elements are filtered.\n3. All elements that match all passed regex patterns are collected, or if previous filter(s) are used, then previously collected elements are filtered.\n4. All elements that fulfill all passed function(s) are collected; if a previous filter(s) is used, then previously collected elements are filtered.\n\n**Notes:**\n\n1. The filtering process always starts from the first filter it finds in the filtering order above. If no tag name(s) are passed but attributes are passed, the process starts from step 2, and so on.\n2. The order in which arguments are passed does not matter. The only order considered is the one explained above.\n\n### Examples\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> page = Fetcher.get('https://quotes.toscrape.com/')\n```\nFind all elements with the tag name `div`.\n```python\n>>> page.find_all('div')\n[

,\n
,\n...]\n```\nFind all div elements with a class that equals `quote`.\n```python\n>>> page.find_all('div', class_='quote')\n[,\n ,\n...]\n```\nSame as above.\n```python\n>>> page.find_all('div', {'class': 'quote'})\n[,\n ,\n...]\n```\nFind all elements with a class that equals `quote`.\n```python\n>>> page.find_all({'class': 'quote'})\n[,\n ,\n...]\n```\nFind all div elements with a class that equals `quote` and contains the element `.text`, which contains the word 'world' in its content.\n```python\n>>> page.find_all('div', {'class': 'quote'}, lambda e: \"world\" in e.css('.text::text').get())\n[]\n```\nFind all elements that have children.\n```python\n>>> page.find_all(lambda element: len(element.children) > 0)\n[,\n Quote...' parent='<html lang=\"en\"><head><meta charset=\"UTF...'>,\n <data='<body> <div class=\"container\"> <div clas...' parent='<html lang=\"en\"><head><meta charset=\"UTF...'>,\n...]\n```\nFind all elements that contain the word 'world' in their content.\n```python\n>>> page.find_all(lambda element: \"world\" in element.text)\n[<data='<span class=\"text\" itemprop=\"text\">โ€œThe...' parent='<div class=\"quote\" itemscope itemtype=\"h...'>,\n <data='<a class=\"tag\" href=\"/tag/world/page/1/\"...' parent='<div class=\"tags\"> Tags: <meta class=\"ke...'>]\n```\nFind all span elements that match the given regex\n```python\n>>> page.find_all('span', re.compile(r'world'))\n[<data='<span class=\"text\" itemprop=\"text\">โ€œThe...' parent='<div class=\"quote\" itemscope itemtype=\"h...'>]\n```\nFind all div and span elements with class 'quote' (No span elements like that, so only div returned)\n```python\n>>> page.find_all(['div', 'span'], {'class': 'quote'})\n[<data='<div class=\"quote\" itemscope itemtype=\"h...' parent='<div class=\"col-md-8\"> <div class=\"quote...'>,\n <data='<div class=\"quote\" itemscope itemtype=\"h...' parent='<div class=\"col-md-8\"> <div class=\"quote...'>,\n...]\n```\nMix things up\n```python\n>>> page.find_all({'itemtype':\"http://schema.org/CreativeWork\"}, 'div').css('.author::text').getall()\n['Albert Einstein',\n 'J.K. Rowling',\n...]\n```\nA bonus pro tip: Find all elements whose `href` attribute's value ends with the word 'Einstein'.\n```python\n>>> page.find_all({'href$': 'Einstein'})\n[<data='<a href=\"/author/Albert-Einstein\">(about...' parent='<span>by <small class=\"author\" itemprop=...'>,\n <data='<a href=\"/author/Albert-Einstein\">(about...' parent='<span>by <small class=\"author\" itemprop=...'>,\n <data='<a href=\"/author/Albert-Einstein\">(about...' parent='<span>by <small class=\"author\" itemprop=...'>]\n```\nAnother pro tip: Find all elements whose `href` attribute's value has '/author/' in it\n```python\n>>> page.find_all({'href*': '/author/'})\n[<data='<a href=\"/author/Albert-Einstein\">(about...' parent='<span>by <small class=\"author\" itemprop=...'>,\n <data='<a href=\"/author/J-K-Rowling\">(about)</a...' parent='<span>by <small class=\"author\" itemprop=...'>,\n <data='<a href=\"/author/Albert-Einstein\">(about...' parent='<span>by <small class=\"author\" itemprop=...'>,\n...]\n```\nAnd so on...\n\n## Generating selectors\nCSS/XPath selectors can be generated for any element, regardless of the method used to find it.\n\nGenerate a short CSS selector for the `url_element` element (if possible, create a short one; otherwise, it's a full selector)\n```python\n>>> url_element = page.find({'href*': '/author/'})\n>>> url_element.generate_css_selector\n'body > div > div:nth-of-type(2) > div > div > span:nth-of-type(2) > a'\n```\nGenerate a full CSS selector for the `url_element` element from the start of the page\n```python\n>>> url_element.generate_full_css_selector\n'body > div > div:nth-of-type(2) > div > div > span:nth-of-type(2) > a'\n```\nGenerate a short XPath selector for the `url_element` element (if possible, create a short one; otherwise, it's a full selector)\n```python\n>>> url_element.generate_xpath_selector\n'//body/div/div[2]/div/div/span[2]/a'\n```\nGenerate a full XPath selector for the `url_element` element from the start of the page\n```python\n>>> url_element.generate_full_xpath_selector\n'//body/div/div[2]/div/div/span[2]/a'\n```\n**Note:** When generating a short selector, Scrapling tries to find a unique element (e.g., one with an `id` attribute) as a stop point. If none exists, the short and full selectors will be identical.\n\n## Using selectors with regular expressions\nSimilar to `parsel`/`scrapy`, `re` and `re_first` methods are available for extracting data using regular expressions. These methods exist in `Selector`, `Selectors`, `TextHandler`, and `TextHandlers`, so they can be used directly on elements even without selecting a text node. See the [TextHandler](main_classes.md#texthandler) class for details.\n\nExamples:\n```python\n>>> page.css('.price_color')[0].re_first(r'[\\d\\.]+')\n'51.77'\n\n>>> page.css('.price_color').re_first(r'[\\d\\.]+')\n'51.77'\n\n>>> page.css('.price_color').re(r'[\\d\\.]+')\n['51.77',\n '53.74',\n '50.10',\n '47.82',\n '54.23',\n...]\n\n>>> page.css('.product_pod h3 a::attr(href)').re(r'catalogue/(.*)/index.html')\n['a-light-in-the-attic_1000',\n 'tipping-the-velvet_999',\n 'soumission_998',\n 'sharp-objects_997',\n...]\n\n>>> filtering_function = lambda e: e.parent.tag == 'h3' and e.parent.parent.has_class('product_pod') # As above selector\n>>> page.find('a', filtering_function).attrib['href'].re(r'catalogue/(.*)/index.html')\n['a-light-in-the-attic_1000']\n\n>>> page.find_by_text('Tipping the Velvet').attrib['href'].re(r'catalogue/(.*)/index.html')\n['tipping-the-velvet_999']\n```\nSee the [TextHandler](main_classes.md#texthandler) class for more details on regex methods." }, { "path": "agent-skill/Scrapling-Skill/references/spiders/advanced.md", "content": "# Advanced usages\n\n## Concurrency Control\n\nThe spider system uses three class attributes to control how aggressively it crawls:\n\n| Attribute | Default | Description |\n|----------------------------------|---------|------------------------------------------------------------------|\n| `concurrent_requests` | `4` | Maximum number of requests being processed at the same time |\n| `concurrent_requests_per_domain` | `0` | Maximum concurrent requests per domain (0 = no per-domain limit) |\n| `download_delay` | `0.0` | Seconds to wait before each request |\n\n```python\nclass PoliteSpider(Spider):\n name = \"polite\"\n start_urls = [\"https://example.com\"]\n\n # Be gentle with the server\n concurrent_requests = 4\n concurrent_requests_per_domain = 2\n download_delay = 1.0 # Wait 1 second between requests\n\n async def parse(self, response: Response):\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\nWhen `concurrent_requests_per_domain` is set, each domain gets its own concurrency limiter in addition to the global limit. This is useful when crawling multiple domains simultaneously โ€” you can allow high global concurrency while being polite to each individual domain.\n\n**Tip:** The `download_delay` parameter adds a fixed wait before every request, regardless of the domain. Use it for simple rate limiting.\n\n### Using uvloop\n\nThe `start()` method accepts a `use_uvloop` parameter to use the faster [uvloop](https://github.com/MagicStack/uvloop)/[winloop](https://github.com/nicktimko/winloop) event loop implementation, if available:\n\n```python\nresult = MySpider().start(use_uvloop=True)\n```\n\nThis can improve throughput for I/O-heavy crawls. You'll need to install `uvloop` (Linux/macOS) or `winloop` (Windows) separately.\n\n## Pause & Resume\n\nThe spider supports graceful pause-and-resume via checkpointing. To enable it, pass a `crawldir` directory to the spider constructor:\n\n```python\nspider = MySpider(crawldir=\"crawl_data/my_spider\")\nresult = spider.start()\n\nif result.paused:\n print(\"Crawl was paused. Run again to resume.\")\nelse:\n print(\"Crawl completed!\")\n```\n\n### How It Works\n\n1. **Pausing**: Press `Ctrl+C` during a crawl. The spider waits for all in-flight requests to finish, saves a checkpoint (pending requests + a set of seen request fingerprints), and then exits.\n2. **Force stopping**: Press `Ctrl+C` a second time to stop immediately without waiting for active tasks.\n3. **Resuming**: Run the spider again with the same `crawldir`. It detects the checkpoint, restores the queue and seen set, and continues from where it left off โ€” skipping `start_requests()`.\n4. **Cleanup**: When a crawl completes normally (not paused), the checkpoint files are deleted automatically.\n\n**Checkpoints are also saved periodically during the crawl (every 5 minutes by default).** \n\nYou can change the interval as follows:\n\n```python\n# Save checkpoint every 2 minutes\nspider = MySpider(crawldir=\"crawl_data/my_spider\", interval=120.0)\n```\n\nThe writing to the disk is atomic, so it's totally safe.\n\n**Tip:** Pressing `Ctrl+C` during a crawl always causes the spider to close gracefully, even if the checkpoint system is not enabled. Doing it again without waiting forces the spider to close immediately.\n\n### Knowing If You're Resuming\n\nThe `on_start()` hook receives a `resuming` flag:\n\n```python\nasync def on_start(self, resuming: bool = False):\n if resuming:\n self.logger.info(\"Resuming from checkpoint!\")\n else:\n self.logger.info(\"Starting fresh crawl\")\n```\n\n## Streaming\n\nFor long-running spiders or applications that need real-time access to scraped items, use the `stream()` method instead of `start()`:\n\n```python\nimport anyio\n\nasync def main():\n spider = MySpider()\n async for item in spider.stream():\n print(f\"Got item: {item}\")\n # Access real-time stats\n print(f\"Items so far: {spider.stats.items_scraped}\")\n print(f\"Requests made: {spider.stats.requests_count}\")\n\nanyio.run(main)\n```\n\nKey differences from `start()`:\n\n- `stream()` must be called from an async context\n- Items are yielded one by one as they're scraped, not collected into a list\n- You can access `spider.stats` during iteration for real-time statistics\n\n**Note:** The full list of all stats that can be accessed by `spider.stats` is explained below [here](#results--statistics).\n\nYou can use it with the checkpoint system too, so it's easy to build UI on top of spiders. UIs that have real-time data and can be paused/resumed.\n\n```python\nimport anyio\n\nasync def main():\n spider = MySpider(crawldir=\"crawl_data/my_spider\")\n async for item in spider.stream():\n print(f\"Got item: {item}\")\n # Access real-time stats\n print(f\"Items so far: {spider.stats.items_scraped}\")\n print(f\"Requests made: {spider.stats.requests_count}\")\n\nanyio.run(main)\n```\nYou can also use `spider.pause()` to shut down the spider in the code above. If you used it without enabling the checkpoint system, it will just close the crawl.\n\n## Lifecycle Hooks\n\nThe spider provides several hooks you can override to add custom behavior at different stages of the crawl:\n\n### on_start\n\nCalled before crawling begins. Use it for setup tasks like loading data or initializing resources:\n\n```python\nasync def on_start(self, resuming: bool = False):\n self.logger.info(\"Spider starting up\")\n # Load seed URLs from a database, initialize counters, etc.\n```\n\n### on_close\n\nCalled after crawling finishes (whether completed or paused). Use it for cleanup:\n\n```python\nasync def on_close(self):\n self.logger.info(\"Spider shutting down\")\n # Close database connections, flush buffers, etc.\n```\n\n### on_error\n\nCalled when a request fails with an exception. Use it for error tracking or custom recovery logic:\n\n```python\nasync def on_error(self, request: Request, error: Exception):\n self.logger.error(f\"Failed: {request.url} - {error}\")\n # Log to error tracker, save failed URL for later, etc.\n```\n\n### on_scraped_item\n\nCalled for every scraped item before it's added to the results. Return the item (modified or not) to keep it, or return `None` to drop it:\n\n```python\nasync def on_scraped_item(self, item: dict) -> dict | None:\n # Drop items without a title\n if not item.get(\"title\"):\n return None\n\n # Modify items (e.g., add timestamps)\n item[\"scraped_at\"] = \"2026-01-01\"\n return item\n```\n\n**Tip:** This hook can also be used to direct items through your own pipelines and drop them from the spider.\n\n### start_requests\n\nOverride `start_requests()` for custom initial request generation instead of using `start_urls`:\n\n```python\nasync def start_requests(self):\n # POST request to log in first\n yield Request(\n \"https://example.com/login\",\n method=\"POST\",\n data={\"user\": \"admin\", \"pass\": \"secret\"},\n callback=self.after_login,\n )\n\nasync def after_login(self, response: Response):\n # Now crawl the authenticated pages\n yield response.follow(\"/dashboard\", callback=self.parse)\n```\n\n## Results & Statistics\n\nThe `CrawlResult` returned by `start()` contains both the scraped items and detailed statistics:\n\n```python\nresult = MySpider().start()\n\n# Items\nprint(f\"Total items: {len(result.items)}\")\nresult.items.to_json(\"output.json\", indent=True)\n\n# Did the crawl complete?\nprint(f\"Completed: {result.completed}\")\nprint(f\"Paused: {result.paused}\")\n\n# Statistics\nstats = result.stats\nprint(f\"Requests: {stats.requests_count}\")\nprint(f\"Failed: {stats.failed_requests_count}\")\nprint(f\"Blocked: {stats.blocked_requests_count}\")\nprint(f\"Offsite filtered: {stats.offsite_requests_count}\")\nprint(f\"Items scraped: {stats.items_scraped}\")\nprint(f\"Items dropped: {stats.items_dropped}\")\nprint(f\"Response bytes: {stats.response_bytes}\")\nprint(f\"Duration: {stats.elapsed_seconds:.1f}s\")\nprint(f\"Speed: {stats.requests_per_second:.1f} req/s\")\n```\n\n### Detailed Stats\n\nThe `CrawlStats` object tracks granular information:\n\n```python\nstats = result.stats\n\n# Status code distribution\nprint(stats.response_status_count)\n# {'status_200': 150, 'status_404': 3, 'status_403': 1}\n\n# Bytes downloaded per domain\nprint(stats.domains_response_bytes)\n# {'example.com': 1234567, 'api.example.com': 45678}\n\n# Requests per session\nprint(stats.sessions_requests_count)\n# {'http': 120, 'stealth': 34}\n\n# Proxies used during the crawl\nprint(stats.proxies)\n# ['http://proxy1:8080', 'http://proxy2:8080']\n\n# Log level counts\nprint(stats.log_levels_counter)\n# {'debug': 200, 'info': 50, 'warning': 3, 'error': 1, 'critical': 0}\n\n# Timing information\nprint(stats.start_time) # Unix timestamp when crawl started\nprint(stats.end_time) # Unix timestamp when crawl finished\nprint(stats.download_delay) # The download delay used (seconds)\n\n# Concurrency settings used\nprint(stats.concurrent_requests) # Global concurrency limit\nprint(stats.concurrent_requests_per_domain) # Per-domain concurrency limit\n\n# Custom stats (set by your spider code)\nprint(stats.custom_stats)\n# {'login_attempts': 3, 'pages_with_errors': 5}\n\n# Export everything as a dict\nprint(stats.to_dict())\n```\n\n## Logging\n\nThe spider has a built-in logger accessible via `self.logger`. It's pre-configured with the spider's name and supports several customization options:\n\n| Attribute | Default | Description |\n|-----------------------|--------------------------------------------------------------|----------------------------------------------------|\n| `logging_level` | `logging.DEBUG` | Minimum log level |\n| `logging_format` | `\"[%(asctime)s]:({spider_name}) %(levelname)s: %(message)s\"` | Log message format |\n| `logging_date_format` | `\"%Y-%m-%d %H:%M:%S\"` | Date format in log messages |\n| `log_file` | `None` | Path to a log file (in addition to console output) |\n\n```python\nimport logging\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n logging_level = logging.INFO\n log_file = \"logs/my_spider.log\"\n\n async def parse(self, response: Response):\n self.logger.info(f\"Processing {response.url}\")\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\nThe log file directory is created automatically if it doesn't exist. Both console and file output use the same format." }, { "path": "agent-skill/Scrapling-Skill/references/spiders/architecture.md", "content": "# Spiders architecture\n\nScrapling's spider system is an async crawling framework designed for concurrent, multi-session crawls with built-in pause/resume support. It brings together Scrapling's parsing engine and fetchers into a unified crawling API while adding scheduling, concurrency control, and checkpointing.\n\n## Data Flow\n\nThe diagram below shows how data flows through the spider system when a crawl is running:\n\nHere's what happens step by step when you run a spider:\n\n1. The **Spider** produces the first batch of `Request` objects. By default, it creates one request for each URL in `start_urls`, but you can override `start_requests()` for custom logic.\n2. The **Scheduler** receives requests and places them in a priority queue, and creates fingerprints for them. Higher-priority requests are dequeued first.\n3. The **Crawler Engine** asks the **Scheduler** to dequeue the next request, respecting concurrency limits (global and per-domain) and download delays. Once the **Crawler Engine** receives the request, it passes it to the **Session Manager**, which routes it to the correct session based on the request's `sid` (session ID).\n4. The **session** fetches the page and returns a [Response](../fetching/choosing.md#response-object) object to the **Crawler Engine**. The engine records statistics and checks for blocked responses. If the response is blocked, the engine retries the request up to `max_blocked_retries` times. Of course, the blocking detection and the retry logic for blocked requests can be customized.\n5. The **Crawler Engine** passes the [Response](../fetching/choosing.md#response-object) to the request's callback. The callback either yields a dictionary, which gets treated as a scraped item, or a follow-up request, which gets sent to the scheduler for queuing.\n6. The cycle repeats from step 2 until the scheduler is empty and no tasks are active, or the spider is paused.\n7. If `crawldir` is set while starting the spider, the **Crawler Engine** periodically saves a checkpoint (pending requests + seen URLs set) to disk. On graceful shutdown (Ctrl+C), a final checkpoint is saved. The next time the spider runs with the same `crawldir`, it resumes from where it left off โ€” skipping `start_requests()` and restoring the scheduler state.\n\n\n## Components\n\n### Spider\n\nThe central class you interact with. You subclass `Spider`, define your `start_urls` and `parse()` method, and optionally configure sessions and override lifecycle hooks.\n\n```python\nfrom scrapling.spiders import Spider, Response, Request\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n\n async def parse(self, response: Response):\n for link in response.css(\"a::attr(href)\").getall():\n yield response.follow(link, callback=self.parse_page)\n\n async def parse_page(self, response: Response):\n yield {\"title\": response.css(\"h1::text\").get(\"\")}\n```\n\n### Crawler Engine\n\nThe engine orchestrates the entire crawl. It manages the main loop, enforces concurrency limits, dispatches requests through the Session Manager, and processes results from callbacks. You don't interact with it directly โ€” the `Spider.start()` and `Spider.stream()` methods handle it for you.\n\n### Scheduler\n\nA priority queue with built-in URL deduplication. Requests are fingerprinted based on their URL, HTTP method, body, and session ID. The scheduler supports `snapshot()` and `restore()` for the checkpoint system, allowing the crawl state to be saved and resumed.\n\n### Session Manager\n\nManages one or more named session instances. Each session is one of:\n\n- [FetcherSession](../fetching/static.md)\n- [AsyncDynamicSession](../fetching/dynamic.md)\n- [AsyncStealthySession](../fetching/stealthy.md)\n\nWhen a request comes in, the Session Manager routes it to the correct session based on the request's `sid` field. Sessions can be started with the spider start (default) or lazily (started on the first use).\n\n### Checkpoint System\n\nAn optional system that, if enabled, saves the crawler's state (pending requests + seen URL fingerprints) to a pickle file on disk. Writes are atomic (temp file + rename) to prevent corruption. Checkpoints are saved periodically at a configurable interval and on graceful shutdown. Upon successful completion (not paused), checkpoint files are automatically cleaned up.\n\n### Output\n\nScraped items are collected in an `ItemList` (a list subclass with `to_json()` and `to_jsonl()` export methods). Crawl statistics are tracked in a `CrawlStats` dataclass which contains a lot of useful info.\n\n\n## Comparison with Scrapy\n\nIf you're coming from Scrapy, here's how Scrapling's spider system maps:\n\n| Concept | Scrapy | Scrapling |\n|--------------------|-------------------------------|-----------------------------------------------------------------|\n| Spider definition | `scrapy.Spider` subclass | `scrapling.spiders.Spider` subclass |\n| Initial requests | `start_requests()` | `async start_requests()` |\n| Callbacks | `def parse(self, response)` | `async def parse(self, response)` |\n| Following links | `response.follow(url)` | `response.follow(url)` |\n| Item output | `yield dict` or `yield Item` | `yield dict` |\n| Request scheduling | Scheduler + Dupefilter | Scheduler with built-in deduplication |\n| Downloading | Downloader + Middlewares | Session Manager with multi-session support |\n| Item processing | Item Pipelines | `on_scraped_item()` hook |\n| Blocked detection | Through custom middlewares | Built-in `is_blocked()` + `retry_blocked_request()` hooks |\n| Concurrency | `CONCURRENT_REQUESTS` setting | `concurrent_requests` class attribute |\n| Domain filtering | `allowed_domains` | `allowed_domains` |\n| Pause/Resume | `JOBDIR` setting | `crawldir` constructor argument |\n| Export | Feed exports | `result.items.to_json()` / `to_jsonl()` or custom through hooks |\n| Running | `scrapy crawl spider_name` | `MySpider().start()` |\n| Streaming | N/A | `async for item in spider.stream()` |\n| Multi-session | N/A | Multiple sessions with different types per spider |" }, { "path": "agent-skill/Scrapling-Skill/references/spiders/getting-started.md", "content": "# Getting started\n\n## Your First Spider\n\nA spider is a class that defines how to crawl and extract data from websites. Here's the simplest possible spider:\n\n```python\nfrom scrapling.spiders import Spider, Response\n\nclass QuotesSpider(Spider):\n name = \"quotes\"\n start_urls = [\"https://quotes.toscrape.com\"]\n\n async def parse(self, response: Response):\n for quote in response.css(\"div.quote\"):\n yield {\n \"text\": quote.css(\"span.text::text\").get(\"\"),\n \"author\": quote.css(\"small.author::text\").get(\"\"),\n }\n```\n\nEvery spider needs three things:\n\n1. **`name`** โ€” A unique identifier for the spider.\n2. **`start_urls`** โ€” A list of URLs to start crawling from.\n3. **`parse()`** โ€” An async generator method that processes each response and yields results.\n\nThe `parse()` method processes each response. You use the same selection methods you'd use with Scrapling's [Selector](../parsing/main_classes.md#selector)/[Response](../fetching/choosing.md#response-object), and `yield` dictionaries to output scraped items.\n\n## Running the Spider\n\nTo run your spider, create an instance and call `start()`:\n\n```python\nresult = QuotesSpider().start()\n```\n\nThe `start()` method handles all the async machinery internally โ€” no need to worry about event loops. While the spider is running, everything that happens is logged to the terminal, and at the end of the crawl, you get very detailed stats.\n\nThose stats are in the returned `CrawlResult` object, which gives you everything you need:\n\n```python\nresult = QuotesSpider().start()\n\n# Access scraped items\nfor item in result.items:\n print(item[\"text\"], \"-\", item[\"author\"])\n\n# Check statistics\nprint(f\"Scraped {result.stats.items_scraped} items\")\nprint(f\"Made {result.stats.requests_count} requests\")\nprint(f\"Took {result.stats.elapsed_seconds:.1f} seconds\")\n\n# Did the crawl finish or was it paused?\nprint(f\"Completed: {result.completed}\")\n```\n\n## Following Links\n\nMost crawls need to follow links across multiple pages. Use `response.follow()` to create follow-up requests:\n\n```python\nfrom scrapling.spiders import Spider, Response\n\nclass QuotesSpider(Spider):\n name = \"quotes\"\n start_urls = [\"https://quotes.toscrape.com\"]\n\n async def parse(self, response: Response):\n # Extract items from the current page\n for quote in response.css(\"div.quote\"):\n yield {\n \"text\": quote.css(\"span.text::text\").get(\"\"),\n \"author\": quote.css(\"small.author::text\").get(\"\"),\n }\n\n # Follow the \"next page\" link\n next_page = response.css(\"li.next a::attr(href)\").get()\n if next_page:\n yield response.follow(next_page, callback=self.parse)\n```\n\n`response.follow()` handles relative URLs automatically โ€” it joins them with the current page's URL. It also sets the current page as the `Referer` header by default.\n\nYou can point follow-up requests at different callback methods for different page types:\n\n```python\nasync def parse(self, response: Response):\n for link in response.css(\"a.product-link::attr(href)\").getall():\n yield response.follow(link, callback=self.parse_product)\n\nasync def parse_product(self, response: Response):\n yield {\n \"name\": response.css(\"h1::text\").get(\"\"),\n \"price\": response.css(\".price::text\").get(\"\"),\n }\n```\n\n**Note:** All callback methods must be async generators (using `async def` and `yield`).\n\n## Exporting Data\n\nThe `ItemList` returned in `result.items` has built-in export methods:\n\n```python\nresult = QuotesSpider().start()\n\n# Export as JSON\nresult.items.to_json(\"quotes.json\")\n\n# Export as JSON with pretty-printing\nresult.items.to_json(\"quotes.json\", indent=True)\n\n# Export as JSON Lines (one JSON object per line)\nresult.items.to_jsonl(\"quotes.jsonl\")\n```\n\nBoth methods create parent directories automatically if they don't exist.\n\n## Filtering Domains\n\nUse `allowed_domains` to restrict the spider to specific domains. This prevents it from accidentally following links to external websites:\n\n```python\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n allowed_domains = {\"example.com\"}\n\n async def parse(self, response: Response):\n for link in response.css(\"a::attr(href)\").getall():\n # Links to other domains are silently dropped\n yield response.follow(link, callback=self.parse)\n```\n\nSubdomains are matched automatically โ€” setting `allowed_domains = {\"example.com\"}` also allows `sub.example.com`, `blog.example.com`, etc.\n\nWhen a request is filtered out, it's counted in `stats.offsite_requests_count` so you can see how many were dropped.\n\n" }, { "path": "agent-skill/Scrapling-Skill/references/spiders/proxy-blocking.md", "content": "# Proxy management and handling Blocks\n\nScrapling's `ProxyRotator` manages proxy rotation across requests. It works with all session types and integrates with the spider's blocked request retry system.\n\n## ProxyRotator\n\nThe `ProxyRotator` class manages a list of proxies and rotates through them automatically. Pass it to any session type via the `proxy_rotator` parameter:\n\n```python\nfrom scrapling.spiders import Spider, Response\nfrom scrapling.fetchers import FetcherSession, ProxyRotator\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n\n def configure_sessions(self, manager):\n rotator = ProxyRotator([\n \"http://proxy1:8080\",\n \"http://proxy2:8080\",\n \"http://user:pass@proxy3:8080\",\n ])\n manager.add(\"default\", FetcherSession(proxy_rotator=rotator))\n\n async def parse(self, response: Response):\n # Check which proxy was used\n print(f\"Proxy used: {response.meta.get('proxy')}\")\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\nEach request automatically gets the next proxy in the rotation. The proxy used is stored in `response.meta[\"proxy\"]` so you can track which proxy fetched which page.\n\n\nBrowser sessions support both string and dict proxy formats:\n\n```python\nfrom scrapling.fetchers import AsyncDynamicSession, AsyncStealthySession, ProxyRotator\n\n# String proxies work for all session types\nrotator = ProxyRotator([\n \"http://proxy1:8080\",\n \"http://proxy2:8080\",\n])\n\n# Dict proxies (Playwright format) work for browser sessions\nrotator = ProxyRotator([\n {\"server\": \"http://proxy1:8080\", \"username\": \"user\", \"password\": \"pass\"},\n {\"server\": \"http://proxy2:8080\"},\n])\n\n# Then inside the spider\ndef configure_sessions(self, manager):\n rotator = ProxyRotator([\"http://proxy1:8080\", \"http://proxy2:8080\"])\n manager.add(\"browser\", AsyncStealthySession(proxy_rotator=rotator))\n```\n\n**Important:**\n\n1. You cannot use the `proxy_rotator` argument together with the static `proxy` or `proxies` parameters on the same session. Pick one approach when configuring the session, and override it per request later if needed.\n2. By default, all browser-based sessions use a persistent browser context with a pool of tabs. However, since browsers can't set a proxy per tab, when you use a `ProxyRotator`, the fetcher will automatically open a separate context for each proxy, with one tab per context. Once the tab's job is done, both the tab and its context are closed.\n\n## Custom Rotation Strategies\n\nBy default, `ProxyRotator` uses cyclic rotation โ€” it iterates through proxies sequentially, wrapping around at the end.\n\nYou can provide a custom strategy function to change this behavior, but it has to match the below signature:\n\n```python\nfrom scrapling.core._types import ProxyType\n\ndef my_strategy(proxies: list, current_index: int) -> tuple[ProxyType, int]:\n ...\n```\n\nIt receives the list of proxies and the current index, and must return the chosen proxy and the next index.\n\nBelow are some examples of custom rotation strategies you can use.\n\n### Random Rotation\n\n```python\nimport random\nfrom scrapling.fetchers import ProxyRotator\n\ndef random_strategy(proxies, current_index):\n idx = random.randint(0, len(proxies) - 1)\n return proxies[idx], idx\n\nrotator = ProxyRotator(\n [\"http://proxy1:8080\", \"http://proxy2:8080\", \"http://proxy3:8080\"],\n strategy=random_strategy,\n)\n```\n\n### Weighted Rotation\n\n```python\nimport random\n\ndef weighted_strategy(proxies, current_index):\n # First proxy gets 60% of traffic, others split the rest\n weights = [60] + [40 // (len(proxies) - 1)] * (len(proxies) - 1)\n proxy = random.choices(proxies, weights=weights, k=1)[0]\n return proxy, current_index # Index doesn't matter for weighted\n\nrotator = ProxyRotator(proxies, strategy=weighted_strategy)\n```\n\n\n## Per-Request Proxy Override\n\nYou can override the rotator for individual requests by passing `proxy=` as a keyword argument:\n\n```python\nasync def parse(self, response: Response):\n # This request uses the rotator's next proxy\n yield response.follow(\"/page1\", callback=self.parse_page)\n\n # This request uses a specific proxy, bypassing the rotator\n yield response.follow(\n \"/special-page\",\n callback=self.parse_page,\n proxy=\"http://special-proxy:8080\",\n )\n```\n\nThis is useful when certain pages require a specific proxy (e.g., a geo-located proxy for region-specific content).\n\n## Blocked Request Handling\n\nThe spider has built-in blocked request detection and retry. By default, it considers the following HTTP status codes blocked: `401`, `403`, `407`, `429`, `444`, `500`, `502`, `503`, `504`.\n\nThe retry system works like this:\n\n1. After a response comes back, the spider calls the `is_blocked(response)` method.\n2. If blocked, it copies the request and calls the `retry_blocked_request()` method so you can modify it before retrying.\n3. The retried request is re-queued with `dont_filter=True` (bypassing deduplication) and lower priority, so it's not retried right away.\n4. This repeats up to `max_blocked_retries` times (default: 3).\n\n**Tip:**\n\n1. On retry, the previous `proxy`/`proxies` kwargs are cleared from the request automatically, so the rotator assigns a fresh proxy.\n2. The `max_blocked_retries` attribute is different than the session retries and doesn't share the counter.\n\n### Custom Block Detection\n\nOverride `is_blocked()` to add your own detection logic:\n\n```python\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n\n async def is_blocked(self, response: Response) -> bool:\n # Check status codes (default behavior)\n if response.status in {403, 429, 503}:\n return True\n\n # Check response content\n body = response.body.decode(\"utf-8\", errors=\"ignore\")\n if \"access denied\" in body.lower() or \"rate limit\" in body.lower():\n return True\n\n return False\n\n async def parse(self, response: Response):\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\n### Customizing Retries\n\nOverride `retry_blocked_request()` to modify the request before retrying. The `max_blocked_retries` attribute controls how many times a blocked request is retried (default: 3):\n\n```python\nfrom scrapling.spiders import Spider, SessionManager, Request, Response\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession\n\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n max_blocked_retries = 5\n\n def configure_sessions(self, manager: SessionManager) -> None:\n manager.add('requests', FetcherSession(impersonate=['chrome', 'firefox', 'safari']))\n manager.add('stealth', AsyncStealthySession(block_webrtc=True), lazy=True)\n\n async def retry_blocked_request(self, request: Request, response: Response) -> Request:\n request.sid = \"stealth\"\n self.logger.info(f\"Retrying blocked request: {request.url}\")\n return request\n\n async def parse(self, response: Response):\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\nWhat happened above is that I left the blocking detection logic unchanged and had the spider mainly use requests until it got blocked, then switch to the stealthy browser.\n\n\nPutting it all together:\n\n```python\nfrom scrapling.spiders import Spider, SessionManager, Request, Response\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession, ProxyRotator\n\n\ncheap_proxies = ProxyRotator([ \"http://proxy1:8080\", \"http://proxy2:8080\"])\n\n# A format acceptable by the browser\nexpensive_proxies = ProxyRotator([\n {\"server\": \"http://residential_proxy1:8080\", \"username\": \"user\", \"password\": \"pass\"},\n {\"server\": \"http://residential_proxy2:8080\", \"username\": \"user\", \"password\": \"pass\"},\n {\"server\": \"http://mobile_proxy1:8080\", \"username\": \"user\", \"password\": \"pass\"},\n {\"server\": \"http://mobile_proxy2:8080\", \"username\": \"user\", \"password\": \"pass\"},\n])\n\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n max_blocked_retries = 5\n\n def configure_sessions(self, manager: SessionManager) -> None:\n manager.add('requests', FetcherSession(impersonate=['chrome', 'firefox', 'safari'], proxy_rotator=cheap_proxies))\n manager.add('stealth', AsyncStealthySession(block_webrtc=True, proxy_rotator=expensive_proxies), lazy=True)\n\n async def retry_blocked_request(self, request: Request, response: Response) -> Request:\n request.sid = \"stealth\"\n self.logger.info(f\"Retrying blocked request: {request.url}\")\n return request\n\n async def parse(self, response: Response):\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\nThe above logic is: requests are made with cheap proxies, such as datacenter proxies, until they are blocked, then retried with higher-quality proxies, such as residential or mobile proxies." }, { "path": "agent-skill/Scrapling-Skill/references/spiders/requests-responses.md", "content": "# Requests & Responses\n\nThis page covers the `Request` object in detail โ€” how to construct requests, pass data between callbacks, control priority and deduplication, and use `response.follow()` for link-following.\n\n## The Request Object\n\nA `Request` represents a URL to be fetched. You create requests either directly or via `response.follow()`:\n\n```python\nfrom scrapling.spiders import Request\n\n# Direct construction\nrequest = Request(\n \"https://example.com/page\",\n callback=self.parse_page,\n priority=5,\n)\n\n# Via response.follow (preferred in callbacks)\nrequest = response.follow(\"/page\", callback=self.parse_page)\n```\n\nHere are all the arguments you can pass to `Request`:\n\n| Argument | Type | Default | Description |\n|---------------|------------|------------|-------------------------------------------------------------------------------------------------------|\n| `url` | `str` | *required* | The URL to fetch |\n| `sid` | `str` | `\"\"` | Session ID โ€” routes the request to a specific session (see [Sessions](sessions.md)) |\n| `callback` | `callable` | `None` | Async generator method to process the response. Defaults to `parse()` |\n| `priority` | `int` | `0` | Higher values are processed first |\n| `dont_filter` | `bool` | `False` | If `True`, skip deduplication (allow duplicate requests) |\n| `meta` | `dict` | `{}` | Arbitrary metadata passed through to the response |\n| `**kwargs` | | | Additional keyword arguments passed to the session's fetch method (e.g., `headers`, `method`, `data`) |\n\nAny extra keyword arguments are forwarded directly to the underlying session. For example, to make a POST request:\n\n```python\nyield Request(\n \"https://example.com/api\",\n method=\"POST\",\n data={\"key\": \"value\"},\n callback=self.parse_result,\n)\n```\n\n## Response.follow()\n\n`response.follow()` is the recommended way to create follow-up requests inside callbacks. It offers several advantages over constructing `Request` objects directly:\n\n- **Relative URLs** are resolved automatically against the current page URL\n- **Referer header** is set to the current page URL by default\n- **Session kwargs** from the original request are inherited (headers, proxy settings, etc.)\n- **Callback, session ID, and priority** are inherited from the original request if not specified\n\n```python\nasync def parse(self, response: Response):\n # Minimal โ€” inherits callback, sid, priority from current request\n yield response.follow(\"/next-page\")\n\n # Override specific fields\n yield response.follow(\n \"/product/123\",\n callback=self.parse_product,\n priority=10,\n )\n\n # Pass additional metadata to\n yield response.follow(\n \"/details\",\n callback=self.parse_details,\n meta={\"category\": \"electronics\"},\n )\n```\n\n| Argument | Type | Default | Description |\n|--------------------|------------|------------|------------------------------------------------------------|\n| `url` | `str` | *required* | URL to follow (absolute or relative) |\n| `sid` | `str` | `\"\"` | Session ID (inherits from original request if empty) |\n| `callback` | `callable` | `None` | Callback method (inherits from original request if `None`) |\n| `priority` | `int` | `None` | Priority (inherits from original request if `None`) |\n| `dont_filter` | `bool` | `False` | Skip deduplication |\n| `meta` | `dict` | `None` | Metadata (merged with existing response meta) |\n| **`referer_flow`** | `bool` | `True` | Set current URL as Referer header |\n| `**kwargs` | | | Merged with original request's session kwargs |\n\n### Disabling Referer Flow\n\nBy default, `response.follow()` sets the `Referer` header to the current page URL. To disable this:\n\n```python\nyield response.follow(\"/page\", referer_flow=False)\n```\n\n## Callbacks\n\nCallbacks are async generator methods on your spider that process responses. They must `yield` one of three types:\n\n- **`dict`** โ€” A scraped item, added to the results\n- **`Request`** โ€” A follow-up request, added to the queue\n- **`None`** โ€” Silently ignored\n\n```python\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n\n async def parse(self, response: Response):\n # Yield items (dicts)\n yield {\"url\": response.url, \"title\": response.css(\"title::text\").get(\"\")}\n\n # Yield follow-up requests\n for link in response.css(\"a::attr(href)\").getall():\n yield response.follow(link, callback=self.parse_page)\n\n async def parse_page(self, response: Response):\n yield {\"content\": response.css(\"article::text\").get(\"\")}\n```\n\n**Note:** All callback methods must be `async def` and use `yield` (not `return`). Even if a callback only yields items with no follow-up requests, it must still be an async generator.\n\n## Request Priority\n\nRequests with higher priority values are processed first. This is useful when some pages are more important to be processed first before others:\n\n```python\nasync def parse(self, response: Response):\n # High priority โ€” process product pages first\n for link in response.css(\"a.product::attr(href)\").getall():\n yield response.follow(link, callback=self.parse_product, priority=10)\n\n # Low priority โ€” pagination links processed after products\n next_page = response.css(\"a.next::attr(href)\").get()\n if next_page:\n yield response.follow(next_page, callback=self.parse, priority=0)\n```\n\nWhen using `response.follow()`, the priority is inherited from the original request unless you specify a new one.\n\n## Deduplication\n\nThe spider automatically deduplicates requests based on a fingerprint computed from the URL, HTTP method, request body, and session ID. If two requests produce the same fingerprint, the second one is silently dropped.\n\nTo allow duplicate requests (e.g., re-visiting a page after login), set `dont_filter=True`:\n\n```python\nyield Request(\"https://example.com/dashboard\", dont_filter=True, callback=self.parse_dashboard)\n\n# Or with response.follow\nyield response.follow(\"/dashboard\", dont_filter=True, callback=self.parse_dashboard)\n```\n\nYou can fine-tune what goes into the fingerprint using class attributes on your spider:\n\n| Attribute | Default | Effect |\n|----------------------|---------|-----------------------------------------------------------------------------------------------------------------|\n| `fp_include_kwargs` | `False` | Include extra request kwargs (arguments you passed to the session fetch, like headers, etc.) in the fingerprint |\n| `fp_keep_fragments` | `False` | Keep URL fragments (`#section`) when computing fingerprints |\n| `fp_include_headers` | `False` | Include request headers in the fingerprint |\n\nFor example, if you need to treat `https://example.com/page#section1` and `https://example.com/page#section2` as different URLs:\n\n```python\nclass MySpider(Spider):\n name = \"my_spider\"\n fp_keep_fragments = True\n # ...\n```\n\n## Request Meta\n\nThe `meta` dictionary lets you pass arbitrary data between callbacks. This is useful when you need context from one page to process another:\n\n```python\nasync def parse(self, response: Response):\n for product in response.css(\"div.product\"):\n category = product.css(\"span.category::text\").get(\"\")\n link = product.css(\"a::attr(href)\").get()\n if link:\n yield response.follow(\n link,\n callback=self.parse_product,\n meta={\"category\": category},\n )\n\nasync def parse_product(self, response: Response):\n yield {\n \"name\": response.css(\"h1::text\").get(\"\"),\n \"price\": response.css(\".price::text\").get(\"\"),\n # Access meta from the request\n \"category\": response.meta.get(\"category\", \"\"),\n }\n```\n\nWhen using `response.follow()`, the meta from the current response is merged with the new meta you provide (new values take precedence).\n\nThe spider system also automatically stores some metadata. For example, the proxy used for a request is available as `response.meta[\"proxy\"]` when proxy rotation is enabled." }, { "path": "agent-skill/Scrapling-Skill/references/spiders/sessions.md", "content": "# Spiders sessions\n\nA spider can use multiple fetcher sessions simultaneously โ€” for example, a fast HTTP session for simple pages and a stealth browser session for protected pages.\n\n## What are Sessions?\n\nA session is a pre-configured fetcher instance that stays alive for the duration of the crawl. Instead of creating a new connection or browser for every request, the spider reuses sessions, which is faster and more resource-efficient.\n\nBy default, every spider creates a single [FetcherSession](../fetching/static.md). You can add more sessions or swap the default by overriding the `configure_sessions()` method, but you have to use the async version of each session only, as the table shows below:\n\n\n| Session Type | Use Case |\n|-------------------------------------------------|------------------------------------------|\n| [FetcherSession](../fetching/static.md) | Fast HTTP requests, no JavaScript |\n| [AsyncDynamicSession](../fetching/dynamic.md) | Browser automation, JavaScript rendering |\n| [AsyncStealthySession](../fetching/stealthy.md) | Anti-bot bypass, Cloudflare, etc. |\n\n\n## Configuring Sessions\n\nOverride `configure_sessions()` on your spider to set up sessions. The `manager` parameter is a `SessionManager` instance โ€” use `manager.add()` to register sessions:\n\n```python\nfrom scrapling.spiders import Spider, Response\nfrom scrapling.fetchers import FetcherSession\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n\n def configure_sessions(self, manager):\n manager.add(\"default\", FetcherSession())\n\n async def parse(self, response: Response):\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\nThe `manager.add()` method takes:\n\n| Argument | Type | Default | Description |\n|--------------|-----------|------------|----------------------------------------------|\n| `session_id` | `str` | *required* | A name to reference this session in requests |\n| `session` | `Session` | *required* | The session instance |\n| `default` | `bool` | `False` | Make this the default session |\n| `lazy` | `bool` | `False` | Start the session only when first used |\n\n**Notes:**\n\n1. In all requests, if you don't specify which session to use, the default session is used. The default session is determined in one of two ways:\n 1. The first session you add to the manager becomes the default automatically.\n 2. The session that gets `default=True` while added to the manager.\n2. The instances you pass of each session don't have to be already started by you; the spider checks on all sessions if they are not already started and starts them.\n3. If you want a specific session to start when used only, then use the `lazy` argument while adding that session to the manager. Example: start the browser only when you need it, not with the spider start.\n\n## Multi-Session Spider\n\nHere's a practical example: use a fast HTTP session for listing pages and a stealth browser for detail pages that have bot protection:\n\n```python\nfrom scrapling.spiders import Spider, Response\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession\n\nclass ProductSpider(Spider):\n name = \"products\"\n start_urls = [\"https://shop.example.com/products\"]\n\n def configure_sessions(self, manager):\n # Fast HTTP for listing pages (default)\n manager.add(\"http\", FetcherSession())\n\n # Stealth browser for protected product pages\n manager.add(\"stealth\", AsyncStealthySession(\n headless=True,\n network_idle=True,\n ))\n\n async def parse(self, response: Response):\n for link in response.css(\"a.product::attr(href)\").getall():\n # Route product pages through the stealth session\n yield response.follow(link, sid=\"stealth\", callback=self.parse_product)\n\n next_page = response.css(\"a.next::attr(href)\").get()\n if next_page:\n yield response.follow(next_page)\n\n async def parse_product(self, response: Response):\n yield {\n \"name\": response.css(\"h1::text\").get(\"\"),\n \"price\": response.css(\".price::text\").get(\"\"),\n }\n```\n\nThe key is the `sid` parameter โ€” it tells the spider which session to use for each request. When you call `response.follow()` without `sid`, the session ID from the original request is inherited.\n\nSessions can also be different instances of the same class with different configurations:\n\n```python\nfrom scrapling.spiders import Spider, Response\nfrom scrapling.fetchers import FetcherSession\n\nclass ProductSpider(Spider):\n name = \"products\"\n start_urls = [\"https://shop.example.com/products\"]\n\n def configure_sessions(self, manager):\n chrome_requests = FetcherSession(impersonate=\"chrome\")\n firefox_requests = FetcherSession(impersonate=\"firefox\")\n\n manager.add(\"chrome\", chrome_requests)\n manager.add(\"firefox\", firefox_requests)\n\n async def parse(self, response: Response):\n for link in response.css(\"a.product::attr(href)\").getall():\n yield response.follow(link, callback=self.parse_product)\n\n next_page = response.css(\"a.next::attr(href)\").get()\n if next_page:\n yield response.follow(next_page, sid=\"firefox\")\n\n async def parse_product(self, response: Response):\n yield {\n \"name\": response.css(\"h1::text\").get(\"\"),\n \"price\": response.css(\".price::text\").get(\"\"),\n }\n```\n\n## Session Arguments\n\nExtra keyword arguments passed to a `Request` (or through `response.follow(**kwargs)`) are forwarded to the session's fetch method. This lets you customize individual requests without changing the session configuration:\n\n```python\nasync def parse(self, response: Response):\n # Pass extra headers for this specific request\n yield Request(\n \"https://api.example.com/data\",\n headers={\"Authorization\": \"Bearer token123\"},\n callback=self.parse_api,\n )\n\n # Use a different HTTP method\n yield Request(\n \"https://example.com/submit\",\n method=\"POST\",\n data={\"field\": \"value\"},\n sid=\"firefox\",\n callback=self.parse_result,\n )\n```\n\n**Warning:** When using `FetcherSession` in spiders, you cannot use `.get()` and `.post()` methods directly. By default, the request is an HTTP GET request; to use another HTTP method, pass it to the `method` argument as in the above example. This unifies the `Request` interface across all session types.\n\nFor browser sessions (`AsyncDynamicSession`, `AsyncStealthySession`), you can pass browser-specific arguments like `wait_selector`, `page_action`, or `extra_headers`:\n\n```python\nasync def parse(self, response: Response):\n # Use Cloudflare solver with the `AsyncStealthySession` we configured above\n yield Request(\n \"https://nopecha.com/demo/cloudflare\",\n sid=\"stealth\",\n callback=self.parse_result,\n solve_cloudflare=True,\n block_webrtc=True,\n hide_canvas=True,\n google_search=True,\n )\n\n yield response.follow(\n \"/dynamic-page\",\n sid=\"browser\",\n callback=self.parse_dynamic,\n wait_selector=\"div.loaded\",\n network_idle=True,\n )\n```\n\n**Warning:** Session arguments (**kwargs) passed from the original request are inherited by `response.follow()`. New kwargs take precedence over inherited ones.\n\n```python\nfrom scrapling.spiders import Spider, Response\nfrom scrapling.fetchers import FetcherSession\n\nclass ProductSpider(Spider):\n name = \"products\"\n start_urls = [\"https://shop.example.com/products\"]\n\n def configure_sessions(self, manager):\n manager.add(\"http\", FetcherSession(impersonate='chrome'))\n\n async def parse(self, response: Response):\n # I don't want the follow request to impersonate a desktop Chrome like the previous request, but a mobile one\n # so I override it like this\n for link in response.css(\"a.product::attr(href)\").getall():\n yield response.follow(link, impersonate=\"chrome131_android\", callback=self.parse_product)\n\n next_page = response.css(\"a.next::attr(href)\").get()\n if next_page:\n yield Request(next_page)\n\n async def parse_product(self, response: Response):\n yield {\n \"name\": response.css(\"h1::text\").get(\"\"),\n \"price\": response.css(\".price::text\").get(\"\"),\n }\n```\n**Note:** Upon spider closure, the manager automatically checks whether any sessions are still running and closes them before closing the spider." }, { "path": "benchmarks.py", "content": "import functools\nimport time\nimport timeit\nfrom statistics import mean\n\nimport requests\nfrom autoscraper import AutoScraper\nfrom bs4 import BeautifulSoup\nfrom lxml import etree, html\nfrom mechanicalsoup import StatefulBrowser\nfrom parsel import Selector\nfrom pyquery import PyQuery as pq\nfrom selectolax.parser import HTMLParser\n\nfrom scrapling import Selector as ScraplingSelector\n\nlarge_html = (\n \"<html><body>\" + '<div class=\"item\">' * 5000 + \"</div>\" * 5000 + \"</body></html>\"\n)\n\n\ndef benchmark(func):\n @functools.wraps(func)\n def wrapper(*args, **kwargs):\n benchmark_name = func.__name__.replace(\"test_\", \"\").replace(\"_\", \" \")\n print(f\"-> {benchmark_name}\", end=\" \", flush=True)\n #

einzelnen Anfrage bis hin zu einem umfassenden Crawl.\n\nSein Parser lernt aus Website-ร„nderungen und lokalisiert Ihre Elemente automatisch neu, wenn sich Seiten aktualisieren. Seine Fetcher umgehen Anti-Bot-Systeme wie Cloudflare Turnstile direkt ab Werk. Und sein Spider-Framework ermรถglicht es Ihnen, auf parallele Multi-Session-Crawls mit Pause & Resume und automatischer Proxy-Rotation hochzuskalieren -- alles in wenigen Zeilen Python. Eine Bibliothek, keine Kompromisse.\n\nBlitzschnelle Crawls mit Echtzeit-Statistiken und Streaming. Von Web Scrapern fรผr Web Scraper und normale Benutzer entwickelt, ist fรผr jeden etwas dabei.\n\n```python\nfrom scrapling.fetchers import Fetcher, AsyncFetcher, StealthyFetcher, DynamicFetcher\nStealthyFetcher.adaptive = True\np = StealthyFetcher.fetch('https://example.com', headless=True, network_idle=True) # Website unbemerkt abrufen!\nproducts = p.css('.product', auto_save=True) # Daten scrapen, die Website-Designรคnderungen รผberleben!\nproducts = p.css('.product', adaptive=True) # Spรคter, wenn sich die Website-Struktur รคndert, `adaptive=True` รผbergeben, um sie zu finden!\n```\nOder auf vollstรคndige Crawls hochskalieren\n```python\nfrom scrapling.spiders import Spider, Response\n\nclass MySpider(Spider):\n name = \"demo\"\n start_urls = [\"https://example.com/\"]\n\n async def parse(self, response: Response):\n for item in response.css('.product'):\n yield {\"title\": item.css('h2::text').get()}\n\nMySpider().start()\n```\n\n<p align=\"center\">\n <a href=\"https://dataimpulse.com/?utm_source=scrapling&utm_medium=banner&utm_campaign=scrapling\" target=\"_blank\" style=\"display:flex; justify-content:center; padding:4px 0;\">\n <img src=\"https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/DataImpulse.png\" alt=\"At DataImpulse, we specialize in developing custom proxy services for your business.

([Demo-Video](https://www.youtube.com/watch?v=qyFk3ZNwOxE))\n\n### Hochleistungs- und praxiserprobte Architektur\n- ๐Ÿš€ **Blitzschnell**: Optimierte Leistung, die die meisten Python-Scraping-Bibliotheken รผbertrifft.\n- ๐Ÿ”‹ **Speichereffizient**: Optimierte Datenstrukturen und Lazy Loading fรผr einen minimalen Speicher-Footprint.\n- โšก **Schnelle JSON-Serialisierung**: 10x schneller als die Standardbibliothek.\n- ๐Ÿ—๏ธ **Praxiserprobt**: Scrapling hat nicht nur eine Testabdeckung von 92% und eine vollstรคndige Type-Hints-Abdeckung, sondern wird seit dem letzten Jahr tรคglich von Hunderten von Web Scrapern verwendet.\n\n### Entwickler-/Web-Scraper-freundliche Erfahrung\n- ๐ŸŽฏ **Interaktive Web-Scraping-Shell**: Optionale integrierte IPython-Shell mit Scrapling-Integration, Shortcuts und neuen Tools zur Beschleunigung der Web-Scraping-Skriptentwicklung, wie das Konvertieren von Curl-Anfragen in Scrapling-Anfragen und das Anzeigen von Anfrageergebnissen in Ihrem Browser.\n- ๐Ÿš€ **Direkt vom Terminal aus verwenden**: Optional kรถnnen Sie Scrapling verwenden, um eine URL zu scrapen, ohne eine einzige Codezeile zu schreiben!\n- ๐Ÿ› ๏ธ **Umfangreiche Navigations-API**: Erweiterte DOM-Traversierung mit Eltern-, Geschwister- und Kind-Navigationsmethoden.\n- ๐Ÿงฌ **Verbesserte Textverarbeitung**: Integrierte Regex, Bereinigungsmethoden und optimierte String-Operationen.\n- ๐Ÿ“ **Automatische Selektorgenerierung**: Robuste CSS/XPath-Selektoren fรผr jedes Element generieren.\n- ๐Ÿ”Œ **Vertraute API**: ร„hnlich wie Scrapy/BeautifulSoup mit denselben Pseudo-Elementen, die in Scrapy/Parsel verwendet werden.\n- ๐Ÿ“˜ **Vollstรคndige Typabdeckung**: Vollstรคndige Type Hints fรผr hervorragende IDE-Unterstรผtzung und Code-Vervollstรคndigung. Die gesamte Codebasis wird bei jeder ร„nderung automatisch mit **PyRight** und **MyPy** gescannt.\n- ๐Ÿ”‹ **Fertiges Docker-Image**: Mit jeder Verรถffentlichung wird automatisch ein Docker-Image erstellt und gepusht, das alle Browser enthรคlt.\n\n## Erste Schritte\n\nHier ein kurzer รœberblick รผber das, was Scrapling kann, ohne zu sehr ins Detail zu gehen.\n\n### Grundlegende Verwendung\nHTTP-Anfragen mit Session-Unterstรผtzung\n```python\nfrom scrapling.fetchers import Fetcher, FetcherSession\n\nwith FetcherSession(impersonate='chrome') as session: # Neueste Version von Chromes TLS-Fingerprint verwenden\n page = session.get('https://quotes.toscrape.com/', stealthy_headers=True)\n quotes = page.css('.quote .text::text').getall()\n\n# Oder einmalige Anfragen verwenden\npage = Fetcher.get('https://quotes.toscrape.com/')\nquotes = page.css('.quote .text::text').getall()\n```\nErweiterter Stealth-Modus\n```python\nfrom scrapling.fetchers import StealthyFetcher, StealthySession\n\nwith StealthySession(headless=True, solve_cloudflare=True) as session: # Browser offen halten, bis Sie fertig sind\n page = session.fetch('https://nopecha.com/demo/cloudflare', google_search=False)\n data = page.css('#padded_content a').getall()\n\n# Oder einmaligen Anfragenstil verwenden: รถffnet den Browser fรผr diese Anfrage und schlieรŸt ihn nach Abschluss\npage = StealthyFetcher.fetch('https://nopecha.com/demo/cloudflare')\ndata = page.css('#padded_content a').getall()\n```\nVollstรคndige Browser-Automatisierung\n```python\nfrom scrapling.fetchers import DynamicFetcher, DynamicSession\n\nwith DynamicSession(headless=True, disable_resources=False, network_idle=True) as session: # Browser offen halten, bis Sie fertig sind\n page = session.fetch('https://quotes.toscrape.com/', load_dom=False)\n data = page.xpath('//span[@class=\"text\"]/text()').getall() # XPath-Selektor, falls bevorzugt\n\n# Oder einmaligen Anfragenstil verwenden: รถffnet den Browser fรผr diese Anfrage und schlieรŸt ihn nach Abschluss\npage = DynamicFetcher.fetch('https://quotes.toscrape.com/')\ndata = page.css('.quote .text::text').getall()\n```\n\n### Spiders\nVollstรคndige Crawler mit parallelen Anfragen, mehreren Session-Typen und Pause & Resume erstellen:\n```python\nfrom scrapling.spiders import Spider, Request, Response\n\nclass QuotesSpider(Spider):\n name = \"quotes\"\n start_urls = [\"https://quotes.toscrape.com/\"]\n concurrent_requests = 10\n\n async def parse(self, response: Response):\n for quote in response.css('.quote'):\n yield {\n \"text\": quote.css('.text::text').get(),\n \"author\": quote.css('.author::text').get(),\n }\n\n next_page = response.css('.next a')\n if next_page:\n yield response.follow(next_page[0].attrib['href'])\n\nresult = QuotesSpider().start()\nprint(f\"{len(result.items)} Zitate gescrapt\")\nresult.items.to_json(\"quotes.json\")\n```\nMehrere Session-Typen in einem einzigen Spider verwenden:\n```python\nfrom scrapling.spiders import Spider, Request, Response\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession\n\nclass MultiSessionSpider(Spider):\n name = \"multi\"\n start_urls = [\"https://example.com/\"]\n\n def configure_sessions(self, manager):\n manager.add(\"fast\", FetcherSession(impersonate=\"chrome\"))\n manager.add(\"stealth\", AsyncStealthySession(headless=True), lazy=True)\n\n async def parse(self, response: Response):\n for link in response.css('a::attr(href)').getall():\n # Geschรผtzte Seiten รผber die Stealth-Session leiten\n if \"protected\" in link:\n yield Request(link, sid=\"stealth\")\n else:\n yield Request(link, sid=\"fast\", callback=self.parse) # Expliziter Callback\n```\nLange Crawls mit Checkpoints pausieren und fortsetzen, indem Sie den Spider so starten:\n```python\nQuotesSpider(crawldir=\"./crawl_data\").start()\n```\nDrรผcken Sie Strg+C, um kontrolliert zu pausieren -- der Fortschritt wird automatisch gespeichert. Wenn Sie den Spider spรคter erneut starten, รผbergeben Sie dasselbe `crawldir`, und er setzt dort fort, wo er aufgehรถrt hat.\n\n### Erweitertes Parsing & Navigation\n```python\nfrom scrapling.fetchers import Fetcher\n\n# Umfangreiche Elementauswahl und Navigation\npage = Fetcher.get('https://quotes.toscrape.com/')\n\n# Zitate mit verschiedenen Auswahlmethoden abrufen\nquotes = page.css('.quote') # CSS-Selektor\nquotes = page.xpath('//div[@class=\"quote\"]') # XPath\nquotes = page.find_all('div', {'class': 'quote'}) # BeautifulSoup-Stil\n# Gleich wie\nquotes = page.find_all('div', class_='quote')\nquotes = page.find_all(['div'], class_='quote')\nquotes = page.find_all(class_='quote') # und so weiter...\n# Element nach Textinhalt finden\nquotes = page.find_by_text('quote', tag='div')\n\n# Erweiterte Navigation\nquote_text = page.css('.quote')[0].css('.text::text').get()\nquote_text = page.css('.quote').css('.text::text').getall() # Verkettete Selektoren\nfirst_quote = page.css('.quote')[0]\nauthor = first_quote.next_sibling.css('.author::text')\nparent_container = first_quote.parent\n\n# Elementbeziehungen und ร„hnlichkeit\nsimilar_elements = first_quote.find_similar()\nbelow_elements = first_quote.below_elements()\n```\nSie kรถnnen den Parser direkt verwenden, wenn Sie keine Websites abrufen mรถchten, wie unten gezeigt:\n```python\nfrom scrapling.parser import Selector\n\npage = Selector(\"<html>...</html>\")\n```\nUnd es funktioniert genau auf die gleiche Weise!\n\n### Beispiele fรผr async Session-Verwaltung\n```python\nimport asyncio\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession, AsyncDynamicSession\n\nasync with FetcherSession(http3=True) as session: # `FetcherSession` ist kontextbewusst und kann sowohl in sync- als auch in async-Mustern arbeiten\n page1 = session.get('https://quotes.toscrape.com/')\n page2 = session.get('https://quotes.toscrape.com/', impersonate='firefox135')\n\n# Async-Session-Verwendung\nasync with AsyncStealthySession(max_pages=2) as session:\n tasks = []\n urls = ['https://example.com/page1', 'https://example.com/page2']\n\n for url in urls:\n task = session.fetch(url)\n tasks.append(task)\n\n print(session.get_pool_stats()) # Optional - Der Status des Browser-Tab-Pools (beschรคftigt/frei/Fehler)\n results = await asyncio.gather(*tasks)\n print(session.get_pool_stats())\n```\n\n## CLI & Interaktive Shell\n\nScrapling enthรคlt eine leistungsstarke Befehlszeilenschnittstelle:\n\n[![asciicast](https://asciinema.org/a/736339.svg)](https://asciinema.org/a/736339)\n\nInteraktive Web-Scraping-Shell starten\n```bash\nscrapling shell\n```\nSeiten direkt ohne Programmierung in eine Datei extrahieren (extrahiert standardmรครŸig den Inhalt im `body`-Tag). Wenn die Ausgabedatei mit `.txt` endet, wird der Textinhalt des Ziels extrahiert. Wenn sie mit `.md` endet, ist es eine Markdown-Darstellung des HTML-Inhalts; wenn sie mit `.html` endet, ist es der HTML-Inhalt selbst.\n```bash\nscrapling extract get 'https://example.com' content.md\nscrapling extract get 'https://example.com' content.txt --css-selector '#fromSkipToProducts' --impersonate 'chrome' # Alle Elemente, die dem CSS-Selektor '#fromSkipToProducts' entsprechen\nscrapling extract fetch 'https://example.com' content.md --css-selector '#fromSkipToProducts' --no-headless\nscrapling extract stealthy-fetch 'https://nopecha.com/demo/cloudflare' captchas.html --css-selector '#padded_content a' --solve-cloudflare\n```\n\n> [!NOTE]\n> Es gibt viele zusรคtzliche Funktionen, aber wir mรถchten diese Seite prรคgnant halten, einschlieรŸlich des MCP-Servers und der interaktiven Web-Scraping-Shell. Schauen Sie sich die vollstรคndige Dokumentation [hier](https://scrapling.readthedocs.io/en/latest/) an\n\n## Leistungsbenchmarks\n\nScrapling ist nicht nur leistungsstark -- es ist auch blitzschnell. Die folgenden Benchmarks vergleichen Scraplings Parser mit den neuesten Versionen anderer beliebter Bibliotheken.\n\n### Textextraktions-Geschwindigkeitstest (5000 verschachtelte Elemente)\n\n| # | Bibliothek | Zeit (ms) | vs Scrapling |\n|---|:-----------------:|:---------:|:------------:|\n| 1 | Scrapling | 2.02 | 1.0x |\n| 2 | Parsel/Scrapy | 2.04 | 1.01 |\n| 3 | Raw Lxml | 2.54 | 1.257 |\n| 4 | PyQuery | 24.17 | ~12x |\n| 5 | Selectolax | 82.63 | ~41x |\n| 6 | MechanicalSoup | 1549.71 | ~767.1x |\n| 7 | BS4 with Lxml | 1584.31 | ~784.3x |\n| 8 | BS4 with html5lib | 3391.91 | ~1679.1x |\n\n\n### Element-ร„hnlichkeit & Textsuche-Leistung\n\nScraplings adaptive Element-Finding-Fรคhigkeiten รผbertreffen Alternativen deutlich:\n\n| Bibliothek | Zeit (ms) | vs Scrapling |\n|-------------|:---------:|:------------:|\n| Scrapling | 2.39 | 1.0x |\n| AutoScraper | 12.45 | 5.209x |\n\n\n> Alle Benchmarks stellen Durchschnittswerte von รผber 100 Durchlรคufen dar. Siehe [benchmarks.py](https://github.com/D4Vinci/Scrapling/blob/main/benchmarks.py) fรผr die Methodik.\n\n## Installation\n\nScrapling erfordert Python 3.10 oder hรถher:\n\n```bash\npip install scrapling\n```\n\nDiese Installation enthรคlt nur die Parser-Engine und ihre Abhรคngigkeiten, ohne Fetcher oder Kommandozeilenabhรคngigkeiten.\n\n### Optionale Abhรคngigkeiten\n\n1. Wenn Sie eine der folgenden zusรคtzlichen Funktionen, die Fetcher oder ihre Klassen verwenden mรถchten, mรผssen Sie die Abhรคngigkeiten der Fetcher und ihre Browser-Abhรคngigkeiten wie folgt installieren:\n ```bash\n pip install \"scrapling[fetchers]\"\n\n scrapling install # normal install\n scrapling install --force # force reinstall\n ```\n\n Dies lรคdt alle Browser zusammen mit ihren Systemabhรคngigkeiten und Fingerprint-Manipulationsabhรคngigkeiten herunter.\n\n Oder Sie kรถnnen sie aus dem Code heraus installieren, anstatt einen Befehl auszufรผhren:\n ```python\n from scrapling.cli import install\n\n install([], standalone_mode=False) # normal install\n install([\"--force\"], standalone_mode=False) # force reinstall\n ```\n\n2. Zusรคtzliche Funktionen:\n - MCP-Server-Funktion installieren:\n ```bash\n pip install \"scrapling[ai]\"\n ```\n - Shell-Funktionen installieren (Web-Scraping-Shell und der `extract`-Befehl):\n ```bash\n pip install \"scrapling[shell]\"\n ```\n - Alles installieren:\n ```bash\n pip install \"scrapling[all]\"\n ```\n Denken Sie daran, dass Sie nach einem dieser Extras (falls noch nicht geschehen) die Browser-Abhรคngigkeiten mit `scrapling install` installieren mรผssen\n\n### Docker\nSie kรถnnen auch ein Docker-Image mit allen Extras und Browsern mit dem folgenden Befehl von DockerHub installieren:\n```bash\ndocker pull pyd4vinci/scrapling\n```\nOder laden Sie es aus der GitHub-Registry herunter:\n```bash\ndocker pull ghcr.io/d4vinci/scrapling:latest\n```\nDieses Image wird automatisch mit GitHub Actions und dem Hauptzweig des Repositorys erstellt und gepusht.\n\n## Beitragen\n\nWir freuen uns รผber Beitrรคge!

([video demo](https://www.youtube.com/watch?v=qyFk3ZNwOxE))\n\n### Arquitectura de Alto Rendimiento y Probada en Batalla\n- ๐Ÿš€ **Ultrarrรกpido**: Rendimiento optimizado que supera a la mayorรญa de las bibliotecas de Web Scraping de Python.\n- ๐Ÿ”‹ **Eficiente en Memoria**: Estructuras de datos optimizadas y carga diferida para una huella de memoria mรญnima.\n- โšก **Serializaciรณn JSON Rรกpida**: 10 veces mรกs rรกpido que la biblioteca estรกndar.\n- ๐Ÿ—๏ธ **Probado en batalla**: Scrapling no solo tiene una cobertura de pruebas del 92% y cobertura completa de type hints, sino que ha sido utilizado diariamente por cientos de Web Scrapers durante el รบltimo aรฑo.\n\n### Experiencia Amigable para Desarrolladores/Web Scrapers\n- ๐ŸŽฏ **Shell Interactivo de Web Scraping**: Shell IPython integrado opcional con integraciรณn de Scrapling, atajos y nuevas herramientas para acelerar el desarrollo de scripts de Web Scraping, como convertir solicitudes curl a solicitudes Scrapling y ver resultados de solicitudes en tu navegador.\n- ๐Ÿš€ **รšsalo directamente desde la Terminal**: Opcionalmente, ยกpuedes usar Scrapling para hacer scraping de una URL sin escribir ni una sola lรญnea de cรณdigo!\n- ๐Ÿ› ๏ธ **API de Navegaciรณn Rica**: Recorrido avanzado del DOM con mรฉtodos de navegaciรณn de padres, hermanos e hijos.\n- ๐Ÿงฌ **Procesamiento de Texto Mejorado**: Mรฉtodos integrados de regex, limpieza y operaciones de cadena optimizadas.\n- ๐Ÿ“ **Generaciรณn Automรกtica de Selectores**: Genera selectores CSS/XPath robustos para cualquier elemento.\n- ๐Ÿ”Œ **API Familiar**: Similar a Scrapy/BeautifulSoup con los mismos pseudo-elementos usados en Scrapy/Parsel.\n- ๐Ÿ“˜ **Cobertura Completa de Tipos**: Type hints completos para excelente soporte de IDE y autocompletado de cรณdigo. Todo el cรณdigo fuente se escanea automรกticamente con **PyRight** y **MyPy** en cada cambio.\n- ๐Ÿ”‹ **Imagen Docker Lista**: Con cada lanzamiento, se construye y publica automรกticamente una imagen Docker que contiene todos los navegadores.\n\n## Primeros Pasos\n\nAquรญ tienes un vistazo rรกpido de lo que Scrapling puede hacer sin entrar en profundidad.\n\n### Uso Bรกsico\nSolicitudes HTTP con soporte de sesiรณn\n```python\nfrom scrapling.fetchers import Fetcher, FetcherSession\n\nwith FetcherSession(impersonate='chrome') as session: # Usa la รบltima versiรณn del fingerprint TLS de Chrome\n page = session.get('https://quotes.toscrape.com/', stealthy_headers=True)\n quotes = page.css('.quote .text::text').getall()\n\n# O usa solicitudes de una sola vez\npage = Fetcher.get('https://quotes.toscrape.com/')\nquotes = page.css('.quote .text::text').getall()\n```\nModo sigiloso avanzado\n```python\nfrom scrapling.fetchers import StealthyFetcher, StealthySession\n\nwith StealthySession(headless=True, solve_cloudflare=True) as session: # Mantรฉn el navegador abierto hasta que termines\n page = session.fetch('https://nopecha.com/demo/cloudflare', google_search=False)\n data = page.css('#padded_content a').getall()\n\n# O usa el estilo de solicitud de una sola vez, abre el navegador para esta solicitud, luego lo cierra despuรฉs de terminar\npage = StealthyFetcher.fetch('https://nopecha.com/demo/cloudflare')\ndata = page.css('#padded_content a').getall()\n```\nAutomatizaciรณn completa del navegador\n```python\nfrom scrapling.fetchers import DynamicFetcher, DynamicSession\n\nwith DynamicSession(headless=True, disable_resources=False, network_idle=True) as session: # Mantรฉn el navegador abierto hasta que termines\n page = session.fetch('https://quotes.toscrape.com/', load_dom=False)\n data = page.xpath('//span[@class=\"text\"]/text()').getall() # Selector XPath si lo prefieres\n\n# O usa el estilo de solicitud de una sola vez, abre el navegador para esta solicitud, luego lo cierra despuรฉs de terminar\npage = DynamicFetcher.fetch('https://quotes.toscrape.com/')\ndata = page.css('.quote .text::text').getall()\n```\n\n### Spiders\nConstruye rastreadores completos con solicitudes concurrentes, mรบltiples tipos de sesiรณn y Pause & Resume:\n```python\nfrom scrapling.spiders import Spider, Request, Response\n\nclass QuotesSpider(Spider):\n name = \"quotes\"\n start_urls = [\"https://quotes.toscrape.com/\"]\n concurrent_requests = 10\n\n async def parse(self, response: Response):\n for quote in response.css('.quote'):\n yield {\n \"text\": quote.css('.text::text').get(),\n \"author\": quote.css('.author::text').get(),\n }\n\n next_page = response.css('.next a')\n if next_page:\n yield response.follow(next_page[0].attrib['href'])\n\nresult = QuotesSpider().start()\nprint(f\"Se extrajeron {len(result.items)} citas\")\nresult.items.to_json(\"quotes.json\")\n```\nUsa mรบltiples tipos de sesiรณn en un solo Spider:\n```python\nfrom scrapling.spiders import Spider, Request, Response\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession\n\nclass MultiSessionSpider(Spider):\n name = \"multi\"\n start_urls = [\"https://example.com/\"]\n\n def configure_sessions(self, manager):\n manager.add(\"fast\", FetcherSession(impersonate=\"chrome\"))\n manager.add(\"stealth\", AsyncStealthySession(headless=True), lazy=True)\n\n async def parse(self, response: Response):\n for link in response.css('a::attr(href)').getall():\n # Enruta las pรกginas protegidas a travรฉs de la sesiรณn sigilosa\n if \"protected\" in link:\n yield Request(link, sid=\"stealth\")\n else:\n yield Request(link, sid=\"fast\", callback=self.parse) # callback explรญcito\n```\nPausa y reanuda rastreos largos con checkpoints ejecutando el Spider asรญ:\n```python\nQuotesSpider(crawldir=\"./crawl_data\").start()\n```\nPresiona Ctrl+C para pausar de forma ordenada โ€” el progreso se guarda automรกticamente. Despuรฉs, cuando inicies el Spider de nuevo, pasa el mismo `crawldir`, y continuarรก desde donde se detuvo.\n\n### Anรกlisis Avanzado y Navegaciรณn\n```python\nfrom scrapling.fetchers import Fetcher\n\n# Selecciรณn rica de elementos y navegaciรณn\npage = Fetcher.get('https://quotes.toscrape.com/')\n\n# Obtรฉn citas con mรบltiples mรฉtodos de selecciรณn\nquotes = page.css('.quote') # Selector CSS\nquotes = page.xpath('//div[@class=\"quote\"]') # XPath\nquotes = page.find_all('div', {'class': 'quote'}) # Estilo BeautifulSoup\n# Igual que\nquotes = page.find_all('div', class_='quote')\nquotes = page.find_all(['div'], class_='quote')\nquotes = page.find_all(class_='quote') # y asรญ sucesivamente...\n# Encuentra elementos por contenido de texto\nquotes = page.find_by_text('quote', tag='div')\n\n# Navegaciรณn avanzada\nquote_text = page.css('.quote')[0].css('.text::text').get()\nquote_text = page.css('.quote').css('.text::text').getall() # Selectores encadenados\nfirst_quote = page.css('.quote')[0]\nauthor = first_quote.next_sibling.css('.author::text')\nparent_container = first_quote.parent\n\n# Relaciones y similitud de elementos\nsimilar_elements = first_quote.find_similar()\nbelow_elements = first_quote.below_elements()\n```\nPuedes usar el parser directamente si no necesitas obtener sitios web, como se muestra a continuaciรณn:\n```python\nfrom scrapling.parser import Selector\n\npage = Selector(\"<html>...</html>\")\n```\nยกY funciona exactamente de la misma manera!\n\n### Ejemplos de Gestiรณn de Session Async\n```python\nimport asyncio\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession, AsyncDynamicSession\n\nasync with FetcherSession(http3=True) as session: # `FetcherSession` es consciente del contexto y puede funcionar tanto en patrones sync/async\n page1 = session.get('https://quotes.toscrape.com/')\n page2 = session.get('https://quotes.toscrape.com/', impersonate='firefox135')\n\n# Uso de sesiรณn async\nasync with AsyncStealthySession(max_pages=2) as session:\n tasks = []\n urls = ['https://example.com/page1', 'https://example.com/page2']\n\n for url in urls:\n task = session.fetch(url)\n tasks.append(task)\n\n print(session.get_pool_stats()) # Opcional - El estado del pool de pestaรฑas del navegador (ocupado/libre/error)\n results = await asyncio.gather(*tasks)\n print(session.get_pool_stats())\n```\n\n## CLI y Shell Interactivo\n\nScrapling incluye una poderosa interfaz de lรญnea de comandos:\n\n[![asciicast](https://asciinema.org/a/736339.svg)](https://asciinema.org/a/736339)\n\nLanzar el Shell interactivo de Web Scraping\n```bash\nscrapling shell\n```\nExtraer pรกginas a un archivo directamente sin programar (Extrae el contenido dentro de la etiqueta `body` por defecto). Si el archivo de salida termina con `.txt`, entonces se extraerรก el contenido de texto del objetivo. Si termina con `.md`, serรก una representaciรณn Markdown del contenido HTML; si termina con `.html`, serรก el contenido HTML en sรญ mismo.\n```bash\nscrapling extract get 'https://example.com' content.md\nscrapling extract get 'https://example.com' content.txt --css-selector '#fromSkipToProducts' --impersonate 'chrome' # Todos los elementos que coinciden con el selector CSS '#fromSkipToProducts'\nscrapling extract fetch 'https://example.com' content.md --css-selector '#fromSkipToProducts' --no-headless\nscrapling extract stealthy-fetch 'https://nopecha.com/demo/cloudflare' captchas.html --css-selector '#padded_content a' --solve-cloudflare\n```\n\n> [!NOTE]\n> Hay muchas caracterรญsticas adicionales, pero queremos mantener esta pรกgina concisa, incluyendo el servidor MCP y el Shell Interactivo de Web Scraping. Consulta la documentaciรณn completa [aquรญ](https://scrapling.readthedocs.io/en/latest/)\n\n## Benchmarks de Rendimiento\n\nScrapling no solo es potente, tambiรฉn es ultrarrรกpido. Los siguientes benchmarks comparan el parser de Scrapling con las รบltimas versiones de otras bibliotecas populares.\n\n### Prueba de Velocidad de Extracciรณn de Texto (5000 elementos anidados)\n\n| # | Biblioteca | Tiempo (ms) | vs Scrapling |\n|---|:-----------------:|:-----------:|:------------:|\n| 1 | Scrapling | 2.02 | 1.0x |\n| 2 | Parsel/Scrapy | 2.04 | 1.01 |\n| 3 | Raw Lxml | 2.54 | 1.257 |\n| 4 | PyQuery | 24.17 | ~12x |\n| 5 | Selectolax | 82.63 | ~41x |\n| 6 | MechanicalSoup | 1549.71 | ~767.1x |\n| 7 | BS4 with Lxml | 1584.31 | ~784.3x |\n| 8 | BS4 with html5lib | 3391.91 | ~1679.1x |\n\n\n### Rendimiento de Similitud de Elementos y Bรบsqueda de Texto\n\nLas capacidades de bรบsqueda adaptativa de elementos de Scrapling superan significativamente a las alternativas:\n\n| Biblioteca | Tiempo (ms) | vs Scrapling |\n|-------------|:-----------:|:------------:|\n| Scrapling | 2.39 | 1.0x |\n| AutoScraper | 12.45 | 5.209x |\n\n\n> Todos los benchmarks representan promedios de mรกs de 100 ejecuciones. Ver [benchmarks.py](https://github.com/D4Vinci/Scrapling/blob/main/benchmarks.py) para la metodologรญa.\n\n## Instalaciรณn\n\nScrapling requiere Python 3.10 o superior:\n\n```bash\npip install scrapling\n```\n\nEsta instalaciรณn solo incluye el motor de anรกlisis y sus dependencias, sin ningรบn fetcher ni dependencias de lรญnea de comandos.\n\n### Dependencias Opcionales\n\n1. Si vas a usar alguna de las caracterรญsticas adicionales a continuaciรณn, los fetchers, o sus clases, necesitarรกs instalar las dependencias de los fetchers y sus dependencias del navegador de la siguiente manera:\n ```bash\n pip install \"scrapling[fetchers]\"\n\n scrapling install # normal install\n scrapling install --force # force reinstall\n ```\n\n Esto descarga todos los navegadores, junto con sus dependencias del sistema y dependencias de manipulaciรณn de fingerprint.\n\n O puedes instalarlos desde el cรณdigo en lugar de ejecutar un comando:\n ```python\n from scrapling.cli import install\n\n install([], standalone_mode=False) # normal install\n install([\"--force\"], standalone_mode=False) # force reinstall\n ```\n\n2. Caracterรญsticas adicionales:\n - Instalar la caracterรญstica del servidor MCP:\n ```bash\n pip install \"scrapling[ai]\"\n ```\n - Instalar caracterรญsticas del Shell (Shell de Web Scraping y el comando `extract`):\n ```bash\n pip install \"scrapling[shell]\"\n ```\n - Instalar todo:\n ```bash\n pip install \"scrapling[all]\"\n ```\n Recuerda que necesitas instalar las dependencias del navegador con `scrapling install` despuรฉs de cualquiera de estos extras (si no lo hiciste ya)\n\n### Docker\nTambiรฉn puedes instalar una imagen Docker con todos los extras y navegadores con el siguiente comando desde DockerHub:\n```bash\ndocker pull pyd4vinci/scrapling\n```\nO descรกrgala desde el registro de GitHub:\n```bash\ndocker pull ghcr.io/d4vinci/scrapling:latest\n```\nEsta imagen se construye y publica automรกticamente usando GitHub Actions y la rama principal del repositorio.\n\n## Contribuir\n\nยกDamos la bienvenida a las contribuciones!

Plus tard, lorsque vous relancez le spider, passez le mรชme `crawldir`, et il reprendra lร  oรน il s'รฉtait arrรชtรฉ.\n\n### Parsing avancรฉ & Navigation\n```python\nfrom scrapling.fetchers import Fetcher\n\n# Sรฉlection riche d'รฉlรฉments et navigation\npage = Fetcher.get('https://quotes.toscrape.com/')\n\n# Obtenir des citations avec plusieurs mรฉthodes de sรฉlection\nquotes = page.css('.quote') # Sรฉlecteur CSS\nquotes = page.xpath('//div[@class=\"quote\"]') # XPath\nquotes = page.find_all('div', {'class': 'quote'}) # Style BeautifulSoup\n# Identique ร \nquotes = page.find_all('div', class_='quote')\nquotes = page.find_all(['div'], class_='quote')\nquotes = page.find_all(class_='quote') # et ainsi de suite...\n# Trouver un รฉlรฉment par contenu textuel\nquotes = page.find_by_text('quote', tag='div')\n\n# Navigation avancรฉe\nquote_text = page.css('.quote')[0].css('.text::text').get()\nquote_text = page.css('.quote').css('.text::text').getall() # Sรฉlecteurs chaรฎnรฉs\nfirst_quote = page.css('.quote')[0]\nauthor = first_quote.next_sibling.css('.author::text')\nparent_container = first_quote.parent\n\n# Relations et similaritรฉ entre รฉlรฉments\nsimilar_elements = first_quote.find_similar()\nbelow_elements = first_quote.below_elements()\n```\nVous pouvez utiliser le parser directement si vous ne souhaitez pas rรฉcupรฉrer de sites web, comme ci-dessous :\n```python\nfrom scrapling.parser import Selector\n\npage = Selector(\"<html>...</html>\")\n```\nEt cela fonctionne exactement de la mรชme maniรจre !\n\n### Exemples de gestion de sessions async\n```python\nimport asyncio\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession, AsyncDynamicSession\n\nasync with FetcherSession(http3=True) as session: # `FetcherSession` est sensible au contexte et peut fonctionner en mode sync comme async\n page1 = session.get('https://quotes.toscrape.com/')\n page2 = session.get('https://quotes.toscrape.com/', impersonate='firefox135')\n\n# Utilisation de session async\nasync with AsyncStealthySession(max_pages=2) as session:\n tasks = []\n urls = ['https://example.com/page1', 'https://example.com/page2']\n\n for url in urls:\n task = session.fetch(url)\n tasks.append(task)\n\n print(session.get_pool_stats()) # Optionnel - Le statut du pool d'onglets du navigateur (occupรฉ/libre/erreur)\n results = await asyncio.gather(*tasks)\n print(session.get_pool_stats())\n```\n\n## CLI & Shell interactif\n\nScrapling inclut une interface en ligne de commande puissante :\n\n[![asciicast](https://asciinema.org/a/736339.svg)](https://asciinema.org/a/736339)\n\nLancer le shell interactif de Web Scraping\n```bash\nscrapling shell\n```\nExtraire des pages directement dans un fichier sans programmation (extrait par dรฉfaut le contenu de la balise `body`). Si le fichier de sortie se termine par `.txt`, le contenu textuel de la cible sera extrait. S'il se termine par `.md`, ce sera une reprรฉsentation Markdown du contenu HTML ; s'il se termine par `.html`, ce sera le contenu HTML lui-mรชme.\n```bash\nscrapling extract get 'https://example.com' content.md\nscrapling extract get 'https://example.com' content.txt --css-selector '#fromSkipToProducts' --impersonate 'chrome' # Tous les รฉlรฉments correspondant au sรฉlecteur CSS '#fromSkipToProducts'\nscrapling extract fetch 'https://example.com' content.md --css-selector '#fromSkipToProducts' --no-headless\nscrapling extract stealthy-fetch 'https://nopecha.com/demo/cloudflare' captchas.html --css-selector '#padded_content a' --solve-cloudflare\n```\n\n> [!NOTE]\n> Il existe de nombreuses fonctionnalitรฉs supplรฉmentaires, mais nous souhaitons garder cette page concise, y compris le serveur MCP et le shell interactif de Web Scraping. Consultez la documentation complรจte [ici](https://scrapling.readthedocs.io/en/latest/)\n\n## Benchmarks de performance\n\nScrapling n'est pas seulement puissant โ€” il est aussi ultra rapide. Les benchmarks suivants comparent le parser de Scrapling avec les derniรจres versions d'autres bibliothรจques populaires.\n\n### Test de vitesse d'extraction de texte (5000 รฉlรฉments imbriquรฉs)\n\n| # | Bibliothรจque | Temps (ms) | vs Scrapling |\n|---|:-----------------:|:----------:|:------------:|\n| 1 | Scrapling | 2.02 | 1.0x |\n| 2 | Parsel/Scrapy | 2.04 | 1.01 |\n| 3 | Raw Lxml | 2.54 | 1.257 |\n| 4 | PyQuery | 24.17 | ~12x |\n| 5 | Selectolax | 82.63 | ~41x |\n| 6 | MechanicalSoup | 1549.71 | ~767.1x |\n| 7 | BS4 with Lxml | 1584.31 | ~784.3x |\n| 8 | BS4 with html5lib | 3391.91 | ~1679.1x |\n\n\n### Performance de similaritรฉ d'รฉlรฉments & recherche textuelle\n\nLes capacitรฉs adaptatives de recherche d'รฉlรฉments de Scrapling surpassent significativement les alternatives :\n\n| Bibliothรจque | Temps (ms) | vs Scrapling |\n|--------------|:----------:|:------------:|\n| Scrapling | 2.39 | 1.0x |\n| AutoScraper | 12.45 | 5.209x |\n\n\n> Tous les benchmarks reprรฉsentent des moyennes de plus de 100 exรฉcutions. Voir [benchmarks.py](https://github.com/D4Vinci/Scrapling/blob/main/benchmarks.py) pour la mรฉthodologie.\n\n## Installation\n\nScrapling nรฉcessite Python 3.10 ou supรฉrieur :\n\n```bash\npip install scrapling\n```\n\nCette installation n'inclut que le moteur de parsing et ses dรฉpendances, sans aucun fetcher ni dรฉpendance en ligne de commande.\n\n### Dรฉpendances optionnelles\n\n1. Si vous allez utiliser l'une des fonctionnalitรฉs supplรฉmentaires ci-dessous, les fetchers ou leurs classes, vous devrez installer les dรฉpendances des fetchers et leurs dรฉpendances navigateur comme suit :\n ```bash\n pip install \"scrapling[fetchers]\"\n\n scrapling install # installation normale\n scrapling install --force # rรฉinstallation forcรฉe\n ```\n\n Cela tรฉlรฉcharge tous les navigateurs, ainsi que leurs dรฉpendances systรจme et les dรฉpendances de manipulation d'empreintes.\n\n Ou vous pouvez les installer depuis le code au lieu d'exรฉcuter une commande :\n ```python\n from scrapling.cli import install\n\n install([], standalone_mode=False) # installation normale\n install([\"--force\"], standalone_mode=False) # rรฉinstallation forcรฉe\n ```\n\n2. Fonctionnalitรฉs supplรฉmentaires :\n - Installer la fonctionnalitรฉ serveur MCP :\n ```bash\n pip install \"scrapling[ai]\"\n ```\n - Installer les fonctionnalitรฉs shell (shell de Web Scraping et la commande `extract`) :\n ```bash\n pip install \"scrapling[shell]\"\n ```\n - Tout installer :\n ```bash\n pip install \"scrapling[all]\"\n ```\n N'oubliez pas que vous devez installer les dรฉpendances navigateur avec `scrapling install` aprรจs l'un de ces extras (si vous ne l'avez pas dรฉjร  fait)\n\n### Docker\nVous pouvez รฉgalement installer une image Docker avec tous les extras et navigateurs avec la commande suivante depuis DockerHub :\n```bash\ndocker pull pyd4vinci/scrapling\n```\nOu tรฉlรฉchargez-la depuis le registre GitHub :\n```bash\ndocker pull ghcr.io/d4vinci/scrapling:latest\n```\nCette image est automatiquement construite et publiรฉe en utilisant GitHub Actions et la branche principale du dรฉpรดt.\n\n## Contribuer\n\nLes contributions sont les bienvenues !

This integration allows you to scrape websites, extract data, and bypass anti-bot protections conversationally through Claude's AI interface or any interface that supports MCP.\n\n## Features\n\nThe Scrapling MCP Server provides six powerful tools for web scraping:\n\n### ๐Ÿš€ Basic HTTP Scraping\n- **`get`**: Fast HTTP requests with browser fingerprint impersonation, generating real browser headers matching the TLS version, HTTP/3, and more!\n- **`bulk_get`**: An async version of the above tool that allows scraping of multiple URLs at the same time!\n\n### ๐ŸŒ Dynamic Content Scraping \n- **`fetch`**: Rapidly fetch dynamic content with Chromium/Chrome browser with complete control over the request/browser, and more!\n- **`bulk_fetch`**: An async version of the above tool that allows scraping of multiple URLs in different browser tabs at the same time!\n\n### ๐Ÿ”’ Stealth Scraping\n- **`stealthy_fetch`**: Uses our Stealthy browser to bypass Cloudflare Turnstile/Interstitial and other anti-bot systems with complete control over the request/browser! \n- **`bulk_stealthy_fetch`**: An async version of the above tool that allows stealth scraping of multiple URLs in different browser tabs at the same time!\n\n### Key Capabilities\n- **Smart Content Extraction**: Convert web pages/elements to Markdown, HTML, or extract a clean version of the text content\n- **CSS Selector Support**: Use the Scrapling engine to target specific elements with precision before handing the content to the AI\n- **Anti-Bot Bypass**: Handle Cloudflare Turnstile, Interstitial, and other protections\n- **Proxy Support**: Use proxies for anonymity and geo-targeting\n- **Browser Impersonation**: Mimic real browsers with TLS fingerprinting, real browser headers matching that version, and more\n- **Parallel Processing**: Scrape multiple URLs concurrently for efficiency\n\n#### But why use Scrapling MCP Server instead of other available tools?\n\nAside from its stealth capabilities and ability to bypass Cloudflare Turnstile/Interstitial, Scrapling's server is the only one that lets you select specific elements to pass to the AI, saving a lot of time and tokens!\n\nThe way other servers work is that they extract the content, then pass it all to the AI to extract the fields you want. This causes the AI to consume far more tokens than needed (from irrelevant content). Scrapling solves this problem by allowing you to pass a CSS selector to narrow down the content you want before passing it to the AI, which makes the whole process much faster and more efficient.\n\nIf you don't know how to write/use CSS selectors, don't worry. You can tell the AI in the prompt to write selectors to match possible fields for you and watch it try different combinations until it finds the right one, as we will show in the examples section.\n\n## Installation\n\nInstall Scrapling with MCP Support, then double-check that the browser dependencies are installed.\n\n```bash\n# Install Scrapling with MCP server dependencies\npip install \"scrapling[ai]\"\n\n# Install browser dependencies\nscrapling install\n```\n\nOr use the Docker image directly from the Docker registry:\n```bash\ndocker pull pyd4vinci/scrapling\n```\nOr download it from the GitHub registry:\n```bash\ndocker pull ghcr.io/d4vinci/scrapling:latest\n```\n\n## Setting up the MCP Server\n\nHere we will explain how to add Scrapling MCP Server to [Claude Desktop](https://claude.ai/download) and [Claude Code](https://www.anthropic.com/claude-code), but the same logic applies to any other chatbot that supports MCP:\n\n### Claude Desktop\n\n1. Open Claude Desktop\n2. Click the hamburger menu (โ˜ฐ) at the top left โ†’ Settings โ†’ Developer โ†’ Edit Config\n3. Add the Scrapling MCP server configuration:\n```json\n\"ScraplingServer\": {\n \"command\": \"scrapling\",\n \"args\": [\n \"mcp\"\n ]\n}\n```\nIf that's the first MCP server you're adding, set the content of the file to this: \n```json\n{\n \"mcpServers\": {\n \"ScraplingServer\": {\n \"command\": \"scrapling\",\n \"args\": [\n \"mcp\"\n ]\n }\n }\n}\n```\nAs per the [official article](https://modelcontextprotocol.io/quickstart/user), this action either creates a new configuration file if none exists or opens your existing configuration. The file is located at\n\n1. **MacOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`\n2. **Windows**: `%APPDATA%\\Claude\\claude_desktop_config.json`\n\nTo ensure it's working, use the full path to the `scrapling` executable. Open the terminal and execute the following command:\n\n1. **MacOS**: `which scrapling`\n2. **Windows**: `where scrapling`\n\nFor me, on my Mac, it returned `/Users/<MyUsername>/.venv/bin/scrapling`, so the config I used in the end is:\n```json\n{\n \"mcpServers\": {\n \"ScraplingServer\": {\n \"command\": \"/Users/<MyUsername>/.venv/bin/scrapling\",\n \"args\": [\n \"mcp\"\n ]\n }\n }\n}\n```\n#### Docker\nIf you are using the Docker image, then it would be something like\n```json\n{\n \"mcpServers\": {\n \"ScraplingServer\": {\n \"command\": \"docker\",\n \"args\": [\n \"run\", \"-i\", \"--rm\", \"scrapling\", \"mcp\"\n ]\n }\n }\n}\n```\n\nThe same logic applies to [Cursor](https://cursor.com/docs/context/mcp), [WindSurf](https://windsurf.com/university/tutorials/configuring-first-mcp-server), and others.\n\n### Claude Code\nHere it's much simpler to do. If you have [Claude Code](https://www.anthropic.com/claude-code) installed, open the terminal and execute the following command:\n\n```bash\nclaude mcp add ScraplingServer \"/Users/<MyUsername>/.venv/bin/scrapling\" mcp\n```\nSame as above, to get Scrapling's executable path, open the terminal and execute the following command:\n\n1. **MacOS**: `which scrapling`\n2. **Windows**: `where scrapling`\n\nHere's the main article from Anthropic on [how to add MCP servers to Claude code](https://docs.anthropic.com/en/docs/claude-code/mcp#option-1%3A-add-a-local-stdio-server) for further details.\n\n\nThen, after you've added the server, you need to completely quit and restart the app you used above. In Claude Desktop, you should see an MCP server indicator (๐Ÿ”ง) in the bottom-right corner of the chat input or see `ScraplingServer` in the `Search and tools` dropdown in the chat input box.\n\n### Streamable HTTP\nAs per version 0.3.6, we have added the ability to make the MCP server use the 'Streamable HTTP' transport mode instead of the traditional 'stdio' transport.\n\nSo instead of using the following command (the 'stdio' one):\n```bash\nscrapling mcp\n```\nUse the following to enable 'Streamable HTTP' transport mode:\n```bash\nscrapling mcp --http\n```\nHence, the default value for the host the server is listening to is '0.0.0.0' and the port is 8000, which both can be configured as below:\n```bash\nscrapling mcp --http --host '127.0.0.1' --port 8000\n```\n\n## Examples\n\nNow we will show you some examples of prompts we used while testing the MCP server, but you are probably more creative than we are and better at prompt engineering than we are :)\n\nWe will gradually go from simple prompts to more complex ones. We will use Claude Desktop for the examples, but the same logic applies to the rest, of course.\n\n1. **Basic Web Scraping**\n\n Extract the main content from a webpage as Markdown:\n \n ```\n Scrape the main content from https://example.com and convert it to markdown format.\n ```\n \n Claude will use the `get` tool to fetch the page and return clean, readable content. If it fails, it will continue retrying every second for 3 attempts, unless you instruct it otherwise. If it fails to retrieve content for any reason, such as protection or if it's a dynamic website, it will automatically try the other tools. If Claude didn't do that automatically for some reason, you can add that to the prompt.\n \n A more optimized version of the same prompt would be:\n ```\n Use regular requests to scrape the main content from https://example.com and convert it to markdown format.\n ```\n This tells Claude which tool to use here, so it doesn't have to guess. Sometimes it will start using normal requests on its own, and at other times, it will assume browsers are better suited for this website without any apparent reason. As a rule of thumb, you should always tell Claude which tool to use to save time and money and get consistent results.\n\n2. **Targeted Data Extraction**\n\n Extract specific elements using CSS selectors:\n \n ```\n Get all product titles from https://shop.example.com using the CSS selector '.product-title'. If the request fails, retry up to 5 times every 10 seconds.\n ```\n \n The server will extract only the elements matching your selector and return them as a structured list. Notice I told it to set the tool to try up to 5 times in case the website has connection issues, but the default setting should be fine for most cases.\n\n3. **E-commerce Data Collection**\n\n Another example of a bit more complex prompt:\n ```\n Extract product information from these e-commerce URLs using bulk browser fetches:\n - https://shop1.com/product-a\n - https://shop2.com/product-b \n - https://shop3.com/product-c\n \n Get the product names, prices, and descriptions from each page.\n ```\n \n Claude will use `bulk_fetch` to concurrently scrape all URLs, then analyze the extracted data.\n\n4. **More advanced workflow**\n\n Let's say I want to get all the action games available on PlayStation's store first page right now. I can use the following prompt to do that:\n ```\n Extract the URLs of all games in this page, then do a bulk request to them and return a list of all action games: https://store.playstation.com/en-us/pages/browse\n ```\n Note that I instructed it to use a bulk request for all the URLs collected. If I hadn't mentioned it, sometimes it works as intended, and other times it makes a separate request to each URL, which takes significantly longer. This prompt takes approximately one minute to complete.\n \n However, because I wasn't specific enough, it actually used the `stealthy_fetch` here and the `bulk_stealthy_fetch` in the second step, which unnecessarily consumed a large number of tokens. A better prompt would be:\n ```\n Use normal requests to extract the URLs of all games in this page, then do a bulk request to them and return a list of all action games: https://store.playstation.com/en-us/pages/browse\n ```\n And if you know how to write CSS selectors, you can instruct Claude to apply the selectors to the elements you want, and it will nearly complete the task immediately.\n ```\n Use normal requests to extract the URLs of all games on the page below, then perform a bulk request to them and return a list of all action games.\n The selector for games in the first page is `[href*=\"/concept/\"]` and the selector for the genre in the second request is `[data-qa=\"gameInfo#releaseInformation#genre-value\"]`.\n \n URL: https://store.playstation.com/en-us/pages/browse\n ```\n\n5. **Get data from a website with Cloudflare protection**\n\n If you think the website you are targeting has Cloudflare protection, tell Claude instead of letting it discover it on its own.\n ```\n What's the price of this product? Be cautious, as it utilizes Cloudflare's Turnstile protection. Make the browser visible while you work.\n\n https://ao.com/product/oo101uk-ninja-woodfire-outdoor-pizza-oven-brown-99357-685.aspx\n ```\n\n6. **Long workflow**\n\n You can, for example, use a prompt like this:\n ```\n Extract all product URLs for the following category, then return the prices and details for the first 3 products.\n \n https://www.arnotts.ie/furniture/bedroom/bed-frames/\n ```\n But a better prompt would be:\n ```\n Go to the following category URL and extract all product URLs using the CSS selector \"a\". Then, fetch the first 3 product pages in parallel and extract each productโ€™s price and details.\n \n Keep the output in markdown format to reduce irrelevant content.\n \n Category URL:\n https://www.arnotts.ie/furniture/bedroom/bed-frames/\n ```\n\nAnd so on, you get the idea. Your creativity is the key here.\n\n## Best Practices\n\nHere is some technical advice for you.\n\n### 1. Choose the Right Tool\n- **`get`**: Fast, simple websites\n- **`fetch`**: Sites with JavaScript/dynamic content \n- **`stealthy_fetch`**: Protected sites, Cloudflare, anti-bot systems\n\n### 2. Optimize Performance\n- Use bulk tools for multiple URLs\n- Disable unnecessary resources\n- Set appropriate timeouts\n- Use CSS selectors for targeted extraction\n\n### 3. Handle Dynamic Content\n- Use `network_idle` for SPAs\n- Set `wait_selector` for specific elements\n- Increase timeout for slow-loading sites\n\n### 4. Data Quality\n- Use `main_content_only=true` to avoid navigation/ads\n- Choose an appropriate `extraction_type` for your use case\n\n## Legal and Ethical Considerations\n\nโš ๏ธ **Important Guidelines:**\n\n- **Check robots.txt**: Visit `https://website.com/robots.txt` to see scraping rules\n- **Respect rate limits**: Don't overwhelm servers with requests\n- **Terms of Service**: Read and comply with website terms\n- **Copyright**: Respect intellectual property rights\n- **Privacy**: Be mindful of personal data protection laws\n- **Commercial use**: Ensure you have permission for business purposes\n\n---\n\n*Built with โค๏ธ by the Scrapling team.

Almost all the options available through the code are also accessible through the command line.\n\n## Quick Start\n\n- **Basic Website Download**\n\n Download a website's text content as clean, readable text:\n ```bash\n scrapling extract get \"https://example.com\" page_content.txt\n ```\n This makes an HTTP GET request and saves the webpage's text content to `page_content.txt`.\n\n- **Save as Different Formats**\n\n Choose your output format by changing the file extension:\n ```bash\n # Convert the HTML content to Markdown, then save it to the file (great for documentation)\n scrapling extract get \"https://blog.example.com\" article.md\n \n # Save the HTML content as it is to the file\n scrapling extract get \"https://example.com\" page.html\n \n # Save a clean version of the text content of the webpage to the file\n scrapling extract get \"https://example.com\" content.txt\n \n # Or use the Docker image with something like this:\n docker run -v $(pwd)/output:/output scrapling extract get \"https://blog.example.com\" /output/article.md \n ```\n\n- **Extract Specific Content**\n\n All commands can use CSS selectors to extract specific parts of the page through `--css-selector` or `-s` as you will see in the examples below.\n\n## Available Commands\n\nYou can display the available commands through `scrapling extract --help` to get the following list:\n```bash\nUsage: scrapling extract [OPTIONS] COMMAND [ARGS]...\n\n Fetch web pages using various fetchers and extract full/selected HTML content as HTML, Markdown, or extract text content.\n\nOptions:\n --help Show this message and exit.\n\nCommands:\n get Perform a GET request and save the content to a file.\n post Perform a POST request and save the content to a file.\n put Perform a PUT request and save the content to a file.\n delete Perform a DELETE request and save the content to a file.\n fetch Use DynamicFetcher to fetch content with browser...\n stealthy-fetch Use StealthyFetcher to fetch content with advanced...\n```\n\nWe will go through each command in detail below.\n\n### HTTP Requests\n\n1. **GET Request**\n\n The most common command for downloading website content:\n \n ```bash\n scrapling extract get [URL] [OUTPUT_FILE] [OPTIONS]\n ```\n \n **Examples:**\n ```bash\n # Basic download\n scrapling extract get \"https://news.site.com\" news.md\n \n # Download with custom timeout\n scrapling extract get \"https://example.com\" content.txt --timeout 60\n \n # Extract only specific content using CSS selectors\n scrapling extract get \"https://blog.example.com\" articles.md --css-selector \"article\"\n \n # Send a request with cookies\n scrapling extract get \"https://scrapling.requestcatcher.com\" content.md --cookies \"session=abc123; user=john\"\n \n # Add user agent\n scrapling extract get \"https://api.site.com\" data.json -H \"User-Agent: MyBot 1.0\"\n \n # Add multiple headers\n scrapling extract get \"https://site.com\" page.html -H \"Accept: text/html\" -H \"Accept-Language: en-US\"\n ```\n Get the available options for the command with `scrapling extract get --help` as follows:\n ```bash\n Usage: scrapling extract get [OPTIONS] URL OUTPUT_FILE\n \n Perform a GET request and save the content to a file.\n \n The output file path can be an HTML file, a Markdown file of the HTML content, or the text content itself.

It provides instant access to all Scrapling features, clever shortcuts, automatic page management, and advanced tools, such as conversion of the curl command.\n\n!!! success \"Prerequisites\"\n\n 1. You've completed or read the [Fetchers basics](../fetching/choosing.md) page to understand what the [Response object](../fetching/choosing.md#response-object) is and which fetcher to use.\n 2. You've completed or read the [Querying elements](../parsing/selection.md) page to understand how to find/extract elements from the [Selector](../parsing/main_classes.md#selector)/[Response](../fetching/choosing.md#response-object) object.\n 3. You've completed or read the [Main classes](../parsing/main_classes.md) page to know what properties/methods the [Response](../fetching/choosing.md#response-object) class is inheriting from the [Selector](../parsing/main_classes.md#selector) class.\n 4. You've completed or read at least one page from the fetchers section to use here for requests: [HTTP requests](../fetching/static.md), [Dynamic websites](../fetching/dynamic.md), or [Dynamic websites with hard protections](../fetching/stealthy.md).\n\n\n## Why use the Interactive Shell?\n\nThe interactive shell transforms web scraping from a slow script-and-run cycle into a fast, exploratory experience. It's perfect for:\n\n- **Rapid prototyping**: Test scraping strategies instantly\n- **Data exploration**: Interactively navigate and extract from websites \n- **Learning Scrapling**: Experiment with features in real-time\n- **Debugging scrapers**: Step through requests and inspect results\n- **Converting workflows**: Transform curl commands from browser DevTools to a Fetcher request in a one-liner\n\n## Getting Started\n\n### Launch the Shell\n\n```bash\n# Start the interactive shell\nscrapling shell\n\n# Execute code and exit (useful for scripting)\nscrapling shell -c \"get('https://quotes.toscrape.com'); print(len(page.css('.quote')))\"\n\n# Set logging level\nscrapling shell --loglevel info\n```\n\nOnce launched, you'll see the Scrapling banner and can immediately start scraping as the video above shows:\n\n```python\n# No imports needed - everything is ready!\n>>> get('https://news.ycombinator.com')\n\n>>> # Explore the page structure\n>>> page.css('a')[:5] # Look at first 5 links\n\n>>> # Refine your selectors\n>>> stories = page.css('.titleline>a')\n>>> len(stories)\n30\n\n>>> # Extract specific data\n>>> for story in stories[:3]:\n... title = story.text\n... url = story['href']\n... print(f\"{title}: {url}\")\n\n>>> # Try different approaches\n>>> titles = page.css('.titleline>a::text') # Direct text extraction\n>>> urls = page.css('.titleline>a::attr(href)') # Direct attribute extraction\n```\n\n## Built-in Shortcuts\n\nThe shell provides convenient shortcuts that eliminate boilerplate code:\n\n- **`get(url, **kwargs)`** - HTTP GET request (instead of `Fetcher.get`)\n- **`post(url, **kwargs)`** - HTTP POST request (instead of `Fetcher.post`)\n- **`put(url, **kwargs)`** - HTTP PUT request (instead of `Fetcher.put`)\n- **`delete(url, **kwargs)`** - HTTP DELETE request (instead of `Fetcher.delete`)\n- **`fetch(url, **kwargs)`** - Browser-based fetch (instead of `DynamicFetcher.fetch`) \n- **`stealthy_fetch(url, **kwargs)`** - Stealthy browser fetch (instead of `StealthyFetcher.fetch`)\n\nThe most commonly used classes are automatically available without any import, including `Fetcher`, `AsyncFetcher`, `DynamicFetcher`, `StealthyFetcher`, and `Selector`.\n\n### Smart Page Management\n\nThe shell automatically tracks your requests and pages:\n\n- **Current Page Access**\n\n The `page` and `response` commands are automatically updated with the last fetched page:\n \n ```python\n >>> get('https://quotes.toscrape.com')\n >>> # 'page' and 'response' both refer to the last fetched page\n >>> page.url\n 'https://quotes.toscrape.com'\n >>> response.status # Same as page.status\n 200\n ```\n\n- **Page History**\n\n The `pages` command keeps track of the last five pages (it's a `Selectors` object):\n \n ```python\n >>> get('https://site1.com')\n >>> get('https://site2.com') \n >>> get('https://site3.com')\n \n >>> # Access last 5 pages\n >>> len(pages) # `Selectors` object with `page` history\n 3\n >>> pages[0].url # First page in history\n 'https://site1.com'\n >>> pages[-1].url # Most recent page\n 'https://site3.com'\n \n >>> # Work with historical pages\n >>> for i, old_page in enumerate(pages):\n ... print(f\"Page {i}: {old_page.url} - {old_page.status}\")\n ```\n\n## Additional helpful commands\n\n### Page Visualization\n\nView scraped pages in your browser:\n\n```python\n>>> get('https://quotes.toscrape.com')\n>>> view(page) # Opens the page HTML in your default browser\n```\n\n### Curl Command Integration\n\nThe shell provides a few functions to help you convert curl commands from the browser DevTools to `Fetcher` requests: `uncurl` and `curl2fetcher`.\n\nFirst, you need to copy a request as a curl command like the following:\n\n<img src=\"../assets/scrapling_shell_curl.png\" title=\"Copying a request as a curl command from Chrome\" alt=\"Copying a request as a curl command from Chrome\" style=\"width: 70%;\"/>\n\n- **Convert Curl command to Request Object**\n\n ```python\n >>> curl_cmd = '''curl 'https://scrapling.requestcatcher.com/post' \\\n ... -X POST \\\n ... -H 'Content-Type: application/json' \\\n ... -d '{\"name\": \"test\", \"value\": 123}' '''\n \n >>> request = uncurl(curl_cmd)\n >>> request.method\n 'post'\n >>> request.url\n 'https://scrapling.requestcatcher.com/post'\n >>> request.headers\n {'Content-Type': 'application/json'}\n ```\n\n- **Execute Curl Command Directly**\n\n ```python\n >>> # Convert and execute in one step\n >>> curl2fetcher(curl_cmd)\n >>> page.status\n 200\n >>> page.json()['json']\n {'name': 'test', 'value': 123}\n ```\n\n### IPython Features\n\nThe shell inherits all IPython capabilities:\n\n```python\n>>> # Magic commands\n>>> %time page = get('https://example.com') # Time execution\n>>> %history # Show command history\n>>> %save filename.py 1-10 # Save commands 1-10 to file\n\n>>> # Tab completion works everywhere\n>>> page.c<TAB> # Shows: css, cookies, headers, etc.\n>>> Fetcher.<TAB> # Shows all Fetcher methods\n\n>>> # Object inspection\n>>> get? # Show get documentation\n```\n\n## Examples\n\nHere are a few examples generated via AI:\n\n#### E-commerce Data Collection\n\n```python\n>>> # Start with product listing page\n>>> catalog = get('https://shop.example.com/products')\n\n>>> # Find product links\n>>> product_links = catalog.css('.product-link::attr(href)')\n>>> print(f\"Found {len(product_links)} products\")\n\n>>> # Sample a few products first\n>>> for link in product_links[:3]:\n... product = get(f\"https://shop.example.com{link}\")\n... name = product.css('.product-name::text').get('')\n... price = product.css('.price::text').get('')\n... print(f\"{name}: {price}\")\n\n>>> # Scale up with sessions for efficiency\n>>> from scrapling.fetchers import FetcherSession\n>>> with FetcherSession() as session:\n... products = []\n... for link in product_links:\n... product = session.get(f\"https://shop.example.com{link}\")\n... products.append({\n... 'name': product.css('.product-name::text').get(''),\n... 'price': product.css('.price::text').get(''),\n... 'url': link\n... })\n```\n\n#### API Integration and Testing\n\n```python\n>>> # Test API endpoints interactively\n>>> response = get('https://jsonplaceholder.typicode.com/posts/1')\n>>> response.json()\n{'userId': 1, 'id': 1, 'title': 'sunt aut...', 'body': 'quia et...'}\n\n>>> # Test POST requests\n>>> new_post = post('https://jsonplaceholder.typicode.com/posts', \n... json={'title': 'Test Post', 'body': 'Test content', 'userId': 1})\n>>> new_post.json()['id']\n101\n\n>>> # Test with different data\n>>> updated = put(f'https://jsonplaceholder.typicode.com/posts/{new_post.json()[\"id\"]}',\n... json={'title': 'Updated Title'})\n```\n\n## Getting Help\n\nIf you need help other than what is available in-terminal, you can:\n\n- [Scrapling Documentation](https://scrapling.readthedocs.io/)\n- [Discord Community](https://discord.gg/EMgGbDceNQ)\n- [GitHub Issues](https://github.com/D4Vinci/Scrapling/issues) \n\nAnd that's it!

It's a great idea to use an online database like that because spiders can share adaptive data with each other.\n\nSo first, to make your storage class work, it must do the big 3:\n\n1. Inherit from the abstract class `scrapling.core.storage.StorageSystemMixin` and accept a string argument, which will be the `url` argument to maintain the library logic.\n2. Use the decorator `functools.lru_cache` on top of the class to follow the Singleton design pattern as other classes.\n3. Implement methods `save` and `retrieve`, as you see from the type hints:\n - The method `save` returns nothing and will get two arguments from the library\n * The first one is of type `lxml.html.HtmlElement`, which is the element itself. It must be converted to a dictionary using the `element_to_dict` function in the submodule `scrapling.core.utils._StorageTools` to maintain the same format, and then saved to your database as you wish.\n * The second one is a string, the identifier used for retrieval. The combination result of this identifier and the `url` argument from initialization must be unique for each row, or the `adaptive` data will be messed up.\n - The method `retrieve` takes a string, which is the identifier; using it with the `url` passed on initialization, the element's dictionary is retrieved from the database and returned if it exists; otherwise, it returns `None`.\n\n> If the instructions weren't clear enough for you, you can check my implementation using SQLite3 in [storage_adaptors](https://github.com/D4Vinci/Scrapling/blob/main/scrapling/core/storage.py) file\n\nIf your class meets these criteria, the rest is straightforward. If you plan to use the library in a threaded application, ensure your class supports it. The default used class is thread-safe.\n\nSome helper functions are added to the abstract class if you want to use them. It's easier to see it for yourself in the [code](https://github.com/D4Vinci/Scrapling/blob/main/scrapling/core/storage.py); it's heavily commented :)\n\n\n## Real-World Example: Redis Storage\n\nHere's a more practical example generated by AI using Redis:\n\n```python\nimport redis\nimport orjson\nfrom functools import lru_cache\nfrom scrapling.core.storage import StorageSystemMixin\nfrom scrapling.core.utils import _StorageTools\n\n@lru_cache(None)\nclass RedisStorage(StorageSystemMixin):\n def __init__(self, host='localhost', port=6379, db=0, url=None):\n super().__init__(url)\n self.redis = redis.Redis(\n host=host,\n port=port,\n db=db,\n decode_responses=False\n )\n \n def save(self, element, identifier: str) -> None:\n # Convert element to dictionary\n element_dict = _StorageTools.element_to_dict(element)\n \n # Create key\n key = f\"scrapling:{self._get_base_url()}:{identifier}\"\n \n # Store as JSON\n self.redis.set(\n key,\n orjson.dumps(element_dict)\n )\n \n def retrieve(self, identifier: str) -> dict | None:\n # Get data\n key = f\"scrapling:{self._get_base_url()}:{identifier}\"\n data = self.redis.get(key)\n \n # Parse JSON if exists\n if data:\n return orjson.loads(data)\n return None\n```" }, { "path": "docs/development/scrapling_custom_types.md", "content": "# Using Scrapling's custom types\n\n> You can take advantage of the custom-made types for Scrapling and use them outside the library if you want. It's better than copying their code, after all :)\n\n### All current types can be imported alone, like below\n```python\n>>> from scrapling.core.custom_types import TextHandler, AttributesHandler\n\n>>> somestring = TextHandler('{}')\n>>> somestring.json()\n'{}'\n>>> somedict_1 = AttributesHandler({'a': 1})\n>>> somedict_2 = AttributesHandler(a=1)\n```\n\nNote that `TextHandler` is a subclass of Python's `str`, so all standard operations/methods that work with Python strings will work.\nIf you want to check the type in your code, it's better to use Python's built-in `issubclass` function.\n\nThe class `AttributesHandler` is a subclass of `collections.abc.Mapping`, so it's immutable (read-only), and all operations are inherited from it. The data passed can be accessed later through the `_data` property, but be careful; it's of type `types.MappingProxyType`, so it's immutable (read-only) as well (faster than `collections.abc.Mapping` by fractions of seconds).\n\nSo, to make it simple for you, if you are new to Python, the same operations and methods from the Python standard `dict` type will all work with the class `AttributesHandler` except for the ones that try to modify the actual data.\n\nIf you want to modify the data inside `AttributesHandler`, you have to convert it to a dictionary first, e.g., using the `dict` function, and then change it outside." }, { "path": "docs/donate.md", "content": "I've been creating all of these projects in my spare time and have invested considerable resources & effort in providing them to the community for free.

Starting with v0.3, all fetchers have separate classes to keep the session running, so for example, a fetcher that uses a browser will keep the browser open till you finish all your requests through it instead of opening multiple browsers. So it depends on your use case.\n\nThis feature was introduced because, before v0.2, Scrapling was only a parsing engine. The target here is to gradually become the one-stop shop for all Web Scraping needs.\n\n> Fetchers are not wrappers built on top of other libraries. However, they only use these libraries as an engine to request/fetch pages. To further clarify this, all fetchers have features that the underlying engines don't, while still fully leveraging those engines and optimizing them for Web Scraping.\n\n## Fetchers Overview\n\nScrapling provides three different fetcher classes with their session classes; each fetcher is designed for a specific use case.\n\nThe following table compares them and can be quickly used for guidance.\n\n\n| Feature | Fetcher | DynamicFetcher | StealthyFetcher |\n|--------------------|---------------------------------------------------|-----------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------|\n| Relative speed | ๐Ÿ‡๐Ÿ‡๐Ÿ‡๐Ÿ‡๐Ÿ‡ | ๐Ÿ‡๐Ÿ‡๐Ÿ‡ | ๐Ÿ‡๐Ÿ‡๐Ÿ‡ |\n| Stealth | โญโญ | โญโญโญ | โญโญโญโญโญ |\n| Anti-Bot options | โญโญ | โญโญโญ | โญโญโญโญโญ |\n| JavaScript loading | โŒ | โœ… | โœ… |\n| Memory Usage | โญ | โญโญโญ | โญโญโญ |\n| Best used for | Basic scraping when HTTP requests alone can do it | - Dynamically loaded websites <br/>- Small automation<br/>- Small-Mid protections | - Dynamically loaded websites <br/>- Small automation <br/>- Small-Complicated protections |\n| Browser(s) | โŒ | Chromium and Google Chrome | Chromium and Google Chrome |\n| Browser API used | โŒ | PlayWright | PlayWright |\n| Setup Complexity | Simple | Simple | Simple |\n\nIn the following pages, we will talk about each one in detail.\n\n## Parser configuration in all fetchers\nAll fetchers share the same import method, as you will see in the upcoming pages\n```python\n>>> from scrapling.fetchers import Fetcher, AsyncFetcher, StealthyFetcher, DynamicFetcher\n```\nThen you use it right away without initializing like this, and it will use the default parser settings:\n```python\n>>> page = StealthyFetcher.fetch('https://example.com') \n```\nIf you want to configure the parser ([Selector class](../parsing/main_classes.md#selector)) that will be used on the response before returning it for you, then do this first:\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> Fetcher.configure(adaptive=True, keep_comments=False, keep_cdata=False) # and the rest\n```\nor\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> Fetcher.adaptive=True\n>>> Fetcher.keep_comments=False\n>>> Fetcher.keep_cdata=False # and the rest\n```\nThen, continue your code as usual.\n\nThe available configuration arguments are: `adaptive`, `adaptive_domain`, `huge_tree`, `keep_comments`, `keep_cdata`, `storage`, and `storage_args`, which are the same ones you give to the [Selector](../parsing/main_classes.md#selector) class. You can display the current configuration anytime by running `<fetcher_class>.display_config()`.\n\n!!! info\n\n The `adaptive` argument is disabled by default; you must enable it to use that feature.\n\n### Set parser config per request\nAs you probably understand, the logic above for setting the parser config will apply globally to all requests/fetches made through that class, and it's intended for simplicity.\n\nIf your use case requires a different configuration for each request/fetch, you can pass a dictionary to the request method (`fetch`/`get`/`post`/...) to an argument named `selector_config`.\n\n## Response Object\nThe `Response` object is the same as the [Selector](../parsing/main_classes.md#selector) class, but it has additional details about the response, like response headers, status, cookies, etc., as shown below:\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> page = Fetcher.get('https://example.com')\n\n>>> page.status # HTTP status code\n>>> page.reason # Status message\n>>> page.cookies # Response cookies as a dictionary\n>>> page.headers # Response headers\n>>> page.request_headers # Request headers\n>>> page.history # Response history of redirections, if any\n>>> page.body # Raw response body as bytes\n>>> page.encoding # Response encoding\n>>> page.meta # Response metadata dictionary (e.g., proxy used). Mainly helpful with the spiders system.\n```\nAll fetchers return the `Response` object.\n\n!!! note\n\n Unlike the [Selector](../parsing/main_classes.md#selector) class, the `Response` class's body is always bytes since v0.4." }, { "path": "docs/fetching/dynamic.md", "content": "# Fetching dynamic websites\n\nHere, we will discuss the `DynamicFetcher` class (formerly `PlayWrightFetcher`). This class provides flexible browser automation with multiple configuration options and little under-the-hood stealth improvements.\n\nAs we will explain later, to automate the page, you need some knowledge of [Playwright's Page API](https://playwright.dev/python/docs/api/class-page).\n\n!!! success \"Prerequisites\"\n\n 1. You've completed or read the [Fetchers basics](../fetching/choosing.md) page to understand what the [Response object](../fetching/choosing.md#response-object) is and which fetcher to use.\n 2. You've completed or read the [Querying elements](../parsing/selection.md) page to understand how to find/extract elements from the [Selector](../parsing/main_classes.md#selector)/[Response](../fetching/choosing.md#response-object) object.\n 3. You've completed or read the [Main classes](../parsing/main_classes.md) page to know what properties/methods the [Response](../fetching/choosing.md#response-object) class is inheriting from the [Selector](../parsing/main_classes.md#selector) class.\n\n## Basic Usage\nYou have one primary way to import this Fetcher, which is the same for all fetchers.\n\n```python\n>>> from scrapling.fetchers import DynamicFetcher\n```\nCheck out how to configure the parsing options [here](choosing.md#parser-configuration-in-all-fetchers)\n\nNow, we will review most of the arguments one by one, using examples. If you want to jump to a table of all arguments for quick reference, [click here](#full-list-of-arguments)\n\n!!! abstract\n\n The async version of the `fetch` method is `async_fetch`, of course.\n\n\nThis fetcher currently provides three main run options that can be combined as desired.\n\nWhich are:\n\n### 1. Vanilla Playwright\n```python\nDynamicFetcher.fetch('https://example.com')\n```\nUsing it in that manner will open a Chromium browser and load the page. There are optimizations for speed, and some stealth goes automatically under the hood, but other than that, there are no tricks or extra features unless you enable some; it's just a plain PlayWright API.\n\n### 2. Real Chrome\n```python\nDynamicFetcher.fetch('https://example.com', real_chrome=True)\n```\nIf you have a Google Chrome browser installed, use this option. It's the same as the first option, but it will use the Google Chrome browser you installed on your device instead of Chromium. This will make your requests look more authentic, so they're less detectable for better results.\n\nIf you don't have Google Chrome installed and want to use this option, you can use the command below in the terminal to install it for the library instead of installing it manually:\n```commandline\nplaywright install chrome\n```\n\n### 3. CDP Connection\n```python\nDynamicFetcher.fetch('https://example.com', cdp_url='ws://localhost:9222')\n```\nInstead of launching a browser locally (Chromium/Google Chrome), you can connect to a remote browser through the [Chrome DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/).\n\n\n!!! note \"Notes:\"\n\n * There was a `stealth` option here, but it was moved to the `StealthyFetcher` class, as explained on the next page, with additional features since version 0.3.13.<br/>\n * This makes it less confusing for new users, easier to maintain, and provides other benefits, as explained on the [StealthyFetcher page](../fetching/stealthy.md).\n\n## Full list of arguments\nScrapling provides many options with this fetcher and its session classes. To make it as simple as possible, we will list the options here and give examples of how to use most of them.\n\n| Argument | Description | Optional |\n|:-------------------:|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:--------:|\n| url | Target url | โŒ |\n| headless | Pass `True` to run the browser in headless/hidden (**default**) or `False` for headful/visible mode. | โœ”๏ธ |\n| disable_resources | Drop requests for unnecessary resources for a speed boost. Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`. | โœ”๏ธ |\n| cookies | Set cookies for the next request. | โœ”๏ธ |\n| useragent | Pass a useragent string to be used. **Otherwise, the fetcher will generate and use a real Useragent of the same browser and version.** | โœ”๏ธ |\n| network_idle | Wait for the page until there are no network connections for at least 500 ms. | โœ”๏ธ |\n| load_dom | Enabled by default, wait for all JavaScript on page(s) to fully load and execute (wait for the `domcontentloaded` state). | โœ”๏ธ |\n| timeout | The timeout (milliseconds) used in all operations and waits through the page. The default is 30,000 ms (30 seconds). | โœ”๏ธ |\n| wait | The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the `Response` object. | โœ”๏ธ |\n| page_action | Added for automation. Pass a function that takes the `page` object and does the necessary automation. | โœ”๏ธ |\n| wait_selector | Wait for a specific css selector to be in a specific state. | โœ”๏ธ |\n| init_script | An absolute path to a JavaScript file to be executed on page creation for all pages in this session. | โœ”๏ธ |\n| wait_selector_state | Scrapling will wait for the given state to be fulfilled for the selector given with `wait_selector`. _Default state is `attached`._ | โœ”๏ธ |\n| google_search | Enabled by default, Scrapling will set a Google referer header. | โœ”๏ธ |\n| extra_headers | A dictionary of extra headers to add to the request. _The referer set by `google_search` takes priority over the referer set here if used together._ | โœ”๏ธ |\n| proxy | The proxy to be used with requests. It can be a string or a dictionary with only the keys 'server', 'username', and 'password'. | โœ”๏ธ |\n| real_chrome | If you have a Chrome browser installed on your device, enable this, and the Fetcher will launch and use an instance of your browser. | โœ”๏ธ |\n| locale | Specify user locale, for example, `en-GB`, `de-DE`, etc. Locale will affect `navigator.language` value, `Accept-Language` request header value, as well as number and date formatting rules. Defaults to the system default locale. | โœ”๏ธ |\n| timezone_id | Changes the timezone of the browser. Defaults to the system timezone. | โœ”๏ธ |\n| cdp_url | Instead of launching a new browser instance, connect to this CDP URL to control real browsers through CDP. | โœ”๏ธ |\n| user_data_dir | Path to a User Data Directory, which stores browser session data like cookies and local storage. The default is to create a temporary directory. **Only Works with sessions** | โœ”๏ธ |\n| extra_flags | A list of additional browser flags to pass to the browser on launch. | โœ”๏ธ |\n| additional_args | Additional arguments to be passed to Playwright's context as additional settings, and they take higher priority than Scrapling's settings. | โœ”๏ธ |\n| selector_config | A dictionary of custom parsing arguments to be used when creating the final `Selector`/`Response` class. | โœ”๏ธ |\n| blocked_domains | A set of domain names to block requests to. Subdomains are also matched (e.g., `\"example.com\"` blocks `\"sub.example.com\"` too). | โœ”๏ธ |\n| proxy_rotator | A `ProxyRotator` instance for automatic proxy rotation. Cannot be combined with `proxy`. | โœ”๏ธ |\n| retries | Number of retry attempts for failed requests. Defaults to 3. | โœ”๏ธ |\n| retry_delay | Seconds to wait between retry attempts. Defaults to 1. | โœ”๏ธ |\n\nIn session classes, all these arguments can be set globally for the session. Still, you can configure each request individually by passing some of the arguments here that can be configured on the browser tab level like: `google_search`, `timeout`, `wait`, `page_action`, `extra_headers`, `disable_resources`, `wait_selector`, `wait_selector_state`, `network_idle`, `load_dom`, `blocked_domains`, `proxy`, and `selector_config`.\n\n!!! note \"Notes:\"\n\n 1. The `disable_resources` option made requests ~25% faster in my tests for some websites and can help save your proxy usage, but be careful with it, as it can cause some websites to never finish loading.\n 2. The `google_search` argument is enabled by default for all requests, setting the referer to `https://www.google.com/`. If used together with `extra_headers`, it takes priority over the referer set there.\n 3. Since version 0.3.13, the `stealth` option has been removed here in favor of the `StealthyFetcher` class, and the `hide_canvas` option has been moved to it. The `disable_webgl` argument has been moved to the `StealthyFetcher` class and renamed as `allow_webgl`.\n 4. If you didn't set a user agent and enabled headless mode, the fetcher will generate a real user agent for the same browser version and use it. If you didn't set a user agent and didn't enable headless mode, the fetcher will use the browser's default user agent, which is the same as in standard browsers in the latest versions.\n\n\n## Examples\nIt's easier to understand with examples, so let's take a look.\n\n### Resource Control\n\n```python\n# Disable unnecessary resources\npage = DynamicFetcher.fetch('https://example.com', disable_resources=True) # Blocks fonts, images, media, etc.\n```\n\n### Domain Blocking\n\n```python\n# Block requests to specific domains (and their subdomains)\npage = DynamicFetcher.fetch('https://example.com', blocked_domains={\"ads.example.com\", \"tracker.net\"})\n```\n\n### Network Control\n\n```python\n# Wait for network idle (Consider fetch to be finished when there are no network connections for at least 500 ms)\npage = DynamicFetcher.fetch('https://example.com', network_idle=True)\n\n# Custom timeout (in milliseconds)\npage = DynamicFetcher.fetch('https://example.com', timeout=30000) # 30 seconds\n\n# Proxy support (It can also be a dictionary with only the keys 'server', 'username', and 'password'.)\npage = DynamicFetcher.fetch('https://example.com', proxy='http://username:password@host:port')\n```\n\n### Proxy Rotation\n\n```python\nfrom scrapling.fetchers import DynamicSession, ProxyRotator\n\n# Set up proxy rotation\nrotator = ProxyRotator([\n \"http://proxy1:8080\",\n \"http://proxy2:8080\",\n \"http://proxy3:8080\",\n])\n\n# Use with session - rotates proxy automatically with each request\nwith DynamicSession(proxy_rotator=rotator, headless=True) as session:\n page1 = session.fetch('https://example1.com')\n page2 = session.fetch('https://example2.com')\n\n # Override rotator for a specific request\n page3 = session.fetch('https://example3.com', proxy='http://specific-proxy:8080')\n```\n\n!!! warning\n\n Remember that by default, all browser-based fetchers and sessions use a persistent browser context with a pool of tabs. However, since browsers can't set a proxy per tab, when you use a `ProxyRotator`, the fetcher will automatically open a separate context for each proxy, with one tab per context. Once the tab's job is done, both the tab and its context are closed.\n\n### Downloading Files\n\n```python\npage = DynamicFetcher.fetch('https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/main_cover.png')\n\nwith open(file='main_cover.png', mode='wb') as f:\n f.write(page.body)\n```\n\nThe `body` attribute of the `Response` object always returns `bytes`.\n\n### Browser Automation\nThis is where your knowledge about [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) comes into play. The function you pass here takes the page object from Playwright's API, performs the desired action, and then the fetcher continues.\n\nThis function is executed immediately after waiting for `network_idle` (if enabled) and before waiting for the `wait_selector` argument, allowing it to be used for purposes beyond automation. You can alter the page as you want.\n\nIn the example below, I used the pages' [mouse events](https://playwright.dev/python/docs/api/class-mouse) to scroll the page with the mouse wheel, then move the mouse.\n```python\nfrom playwright.sync_api import Page\n\ndef scroll_page(page: Page):\n page.mouse.wheel(10, 0)\n page.mouse.move(100, 400)\n page.mouse.up()\n\npage = DynamicFetcher.fetch('https://example.com', page_action=scroll_page)\n```\nOf course, if you use the async fetch version, the function must also be async.\n```python\nfrom playwright.async_api import Page\n\nasync def scroll_page(page: Page):\n await page.mouse.wheel(10, 0)\n await page.mouse.move(100, 400)\n await page.mouse.up()\n\npage = await DynamicFetcher.async_fetch('https://example.com', page_action=scroll_page)\n```\n\n### Wait Conditions\n\n```python\n# Wait for the selector\npage = DynamicFetcher.fetch(\n 'https://example.com',\n wait_selector='h1',\n wait_selector_state='visible'\n)\n```\nThis is the last wait the fetcher will do before returning the response (if enabled). You pass a CSS selector to the `wait_selector` argument, and the fetcher will wait for the state you passed in the `wait_selector_state` argument to be fulfilled. If you didn't pass a state, the default would be `attached`, which means it will wait for the element to be present in the DOM.\n\nAfter that, if `load_dom` is enabled (the default), the fetcher will check again to see if all JavaScript files are loaded and executed (in the `domcontentloaded` state) or continue waiting. If you have enabled `network_idle`, the fetcher will wait for `network_idle` to be fulfilled again, as explained above.\n\nThe states the fetcher can wait for can be any of the following ([source](https://playwright.dev/python/docs/api/class-page#page-wait-for-selector)):\n\n- `attached`: Wait for an element to be present in the DOM.\n- `detached`: Wait for an element to not be present in the DOM.\n- `visible`: wait for an element to have a non-empty bounding box and no `visibility:hidden`. Note that an element without any content or with `display:none` has an empty bounding box and is not considered visible.\n- `hidden`: wait for an element to be either detached from the DOM, or have an empty bounding box, or `visibility:hidden`. This is opposite to the `'visible'` option.\n\n### Some Stealth Features\n\n```python\npage = DynamicFetcher.fetch(\n 'https://example.com',\n google_search=True,\n useragent='Mozilla/5.0...', # Custom user agent\n locale='en-US', # Set browser locale\n)\n```\n\n### General example\n```python\nfrom scrapling.fetchers import DynamicFetcher\n\ndef scrape_dynamic_content():\n # Use Playwright for JavaScript content\n page = DynamicFetcher.fetch(\n 'https://example.com/dynamic',\n network_idle=True,\n wait_selector='.content'\n )\n \n # Extract dynamic content\n content = page.css('.content')\n \n return {\n 'title': content.css('h1::text').get(),\n 'items': [\n item.text for item in content.css('.item')\n ]\n }\n```\n\n## Session Management\n\nTo keep the browser open until you make multiple requests with the same configuration, use `DynamicSession`/`AsyncDynamicSession` classes. Those classes can accept all the arguments that the `fetch` function can take, which enables you to specify a config for the entire session.\n\n```python\nfrom scrapling.fetchers import DynamicSession\n\n# Create a session with default configuration\nwith DynamicSession(\n headless=True,\n disable_resources=True,\n real_chrome=True\n) as session:\n # Make multiple requests with the same browser instance\n page1 = session.fetch('https://example1.com')\n page2 = session.fetch('https://example2.com')\n page3 = session.fetch('https://dynamic-site.com')\n \n # All requests reuse the same tab on the same browser instance\n```\n\n### Async Session Usage\n\n```python\nimport asyncio\nfrom scrapling.fetchers import AsyncDynamicSession\n\nasync def scrape_multiple_sites():\n async with AsyncDynamicSession(\n network_idle=True,\n timeout=30000,\n max_pages=3\n ) as session:\n # Make async requests with shared browser configuration\n pages = await asyncio.gather(\n session.fetch('https://spa-app1.com'),\n session.fetch('https://spa-app2.com'),\n session.fetch('https://dynamic-content.com')\n )\n return pages\n```\n\nYou may have noticed the `max_pages` argument. This is a new argument that enables the fetcher to create a **rotating pool of Browser tabs**. Instead of using a single tab for all your requests, you set a limit on the maximum number of pages that can be displayed at once. With each request, the library will close all tabs that have finished their task and check if the number of the current tabs is lower than the maximum allowed number of pages/tabs, then:\n\n1. If you are within the allowed range, the fetcher will create a new tab for you, and then all is as normal.\n2. Otherwise, it will keep checking every subsecond if creating a new tab is allowed or not for 60 seconds, then raise `TimeoutError`. This can happen when the website you are fetching becomes unresponsive.\n\nThis logic allows for multiple URLs to be fetched at the same time in the same browser, which saves a lot of resources, but most importantly, is so fast :)\n\nIn versions 0.3 and 0.3.1, the pool was reusing finished tabs to save more resources/time. That logic proved flawed, as it's nearly impossible to protect pages/tabs from contamination by the previous configuration used in the request before this one.\n\n### Session Benefits\n\n- **Browser reuse**: Much faster subsequent requests by reusing the same browser instance.\n- **Cookie persistence**: Automatic cookie and session state handling as any browser does automatically.\n- **Consistent fingerprint**: Same browser fingerprint across all requests.\n- **Memory efficiency**: Better resource usage compared to launching new browsers with each fetch.\n\n## When to Use\n\nUse DynamicFetcher when:\n\n- Need browser automation\n- Want multiple browser options\n- Using a real Chrome browser\n- Need custom browser config\n- Want a few stealth options \n\nIf you want more stealth and control without much config, check out the [StealthyFetcher](stealthy.md)." }, { "path": "docs/fetching/static.md", "content": "# HTTP requests\n\nThe `Fetcher` class provides rapid and lightweight HTTP requests using the high-performance `curl_cffi` library with a lot of stealth capabilities.\n\n!!! success \"Prerequisites\"\n\n 1.

It also sets a Google referer header.\n- **follow_redirects**: As the name implies, tell the fetcher to follow redirections. **Enabled by default**\n- **timeout**: The number of seconds to wait for each request to be finished. **Defaults to 30 seconds**.\n- **retries**: The number of retries that the fetcher will do for failed requests. **Defaults to three retries**.\n- **retry_delay**: Number of seconds to wait between retry attempts. **Defaults to 1 second**.\n- **impersonate**: Impersonate specific browsers' TLS fingerprints. Accepts browser strings or a list of them like `\"chrome110\"`, `\"firefox102\"`, `\"safari15_5\"` to use specific versions or `\"chrome\"`, `\"firefox\"`, `\"safari\"`, `\"edge\"` to automatically use the latest version available. This makes your requests appear to come from real browsers at the TLS level. If you pass it a list of strings, it will choose a random one with each request. **Defaults to the latest available Chrome version.**\n- **http3**: Use HTTP/3 protocol for requests. **Defaults to False**. It might be problematic if used with `impersonate`.\n- **cookies**: Cookies to use in the request. Can be a dictionary of `nameโ†’value` or a list of dictionaries.\n- **proxy**: As the name implies, the proxy for this request is used to route all traffic (HTTP and HTTPS). The format accepted here is `http://username:password@localhost:8030`.\n- **proxy_auth**: HTTP basic auth for proxy, tuple of (username, password).\n- **proxies**: Dict of proxies to use. Format: `{\"http\": proxy_url, \"https\": proxy_url}`.\n- **proxy_rotator**: A `ProxyRotator` instance for automatic proxy rotation. Cannot be combined with `proxy` or `proxies`.\n- **headers**: Headers to include in the request. Can override any header generated by the `stealthy_headers` argument\n- **max_redirects**: Maximum number of redirects. **Defaults to 30**, use -1 for unlimited.\n- **verify**: Whether to verify HTTPS certificates. **Defaults to True**.\n- **cert**: Tuple of (cert, key) filenames for the client certificate.\n- **selector_config**: A dictionary of custom parsing arguments to be used when creating the final `Selector`/`Response` class.\n\n!!! note \"Notes:\"\n\n 1. The currently available browsers to impersonate are (`\"edge\"`, `\"chrome\"`, `\"chrome_android\"`, `\"safari\"`, `\"safari_beta\"`, `\"safari_ios\"`, `\"safari_ios_beta\"`, `\"firefox\"`, `\"tor\"`)<br/>\n 2. The available browsers to impersonate, along with their corresponding versions, are automatically displayed in the argument autocompletion and updated with each `curl_cffi` update.<br/>\n 3. If any of the arguments `impersonate` or `stealthy_headers` are enabled, the fetchers will automatically generate real browser headers that match the browser version used.\n\nOther than this, for further customization, you can pass any arguments that `curl_cffi` supports for any method if that method doesn't already support them.\n\n### HTTP Methods\nThere are additional arguments for each method, depending on the method, such as `params` for GET requests and `data`/`json` for POST/PUT/DELETE requests.\n\nExamples are the best way to explain this:\n\n> Hence: `OPTIONS` and `HEAD` methods are not supported.\n#### GET\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> # Basic GET\n>>> page = Fetcher.get('https://example.com')\n>>> page = Fetcher.get('https://scrapling.requestcatcher.com/get', stealthy_headers=True, follow_redirects=True)\n>>> page = Fetcher.get('https://scrapling.requestcatcher.com/get', proxy='http://username:password@localhost:8030')\n>>> # With parameters\n>>> page = Fetcher.get('https://example.com/search', params={'q': 'query'})\n>>>\n>>> # With headers\n>>> page = Fetcher.get('https://example.com', headers={'User-Agent': 'Custom/1.0'})\n>>> # Basic HTTP authentication\n>>> page = Fetcher.get(\"https://example.com\", auth=(\"my_user\", \"password123\"))\n>>> # Browser impersonation\n>>> page = Fetcher.get('https://example.com', impersonate='chrome')\n>>> # HTTP/3 support\n>>> page = Fetcher.get('https://example.com', http3=True)\n```\nAnd for asynchronous requests, it's a small adjustment \n```python\n>>> from scrapling.fetchers import AsyncFetcher\n>>> # Basic GET\n>>> page = await AsyncFetcher.get('https://example.com')\n>>> page = await AsyncFetcher.get('https://scrapling.requestcatcher.com/get', stealthy_headers=True, follow_redirects=True)\n>>> page = await AsyncFetcher.get('https://scrapling.requestcatcher.com/get', proxy='http://username:password@localhost:8030')\n>>> # With parameters\n>>> page = await AsyncFetcher.get('https://example.com/search', params={'q': 'query'})\n>>>\n>>> # With headers\n>>> page = await AsyncFetcher.get('https://example.com', headers={'User-Agent': 'Custom/1.0'})\n>>> # Basic HTTP authentication\n>>> page = await AsyncFetcher.get(\"https://example.com\", auth=(\"my_user\", \"password123\"))\n>>> # Browser impersonation\n>>> page = await AsyncFetcher.get('https://example.com', impersonate='chrome110')\n>>> # HTTP/3 support\n>>> page = await AsyncFetcher.get('https://example.com', http3=True)\n```\nNeedless to say, the `page` object in all cases is [Response](choosing.md#response-object) object, which is a [Selector](../parsing/main_classes.md#selector) as we said, so you can use it directly\n```python\n>>> page.css('.something.something')\n\n>>> page = Fetcher.get('https://api.github.com/events')\n>>> page.json()\n[{'id': '<redacted>',\n 'type': 'PushEvent',\n 'actor': {'id': '<redacted>',\n 'login': '<redacted>',\n 'display_login': '<redacted>',\n 'gravatar_id': '',\n 'url': 'https://api.github.com/users/<redacted>',\n 'avatar_url': 'https://avatars.githubusercontent.com/u/<redacted>'},\n 'repo': {'id': '<redacted>',\n...\n```\n#### POST\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> # Basic POST\n>>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, params={'q': 'query'})\n>>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, stealthy_headers=True, follow_redirects=True)\n>>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030', impersonate=\"chrome\")\n>>> # Another example of form-encoded data\n>>> page = Fetcher.post('https://example.com/submit', data={'username': 'user', 'password': 'pass'}, http3=True)\n>>> # JSON data\n>>> page = Fetcher.post('https://example.com/api', json={'key': 'value'})\n```\nAnd for asynchronous requests, it's a small adjustment\n```python\n>>> from scrapling.fetchers import AsyncFetcher\n>>> # Basic POST\n>>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'})\n>>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, stealthy_headers=True, follow_redirects=True)\n>>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030', impersonate=\"chrome\")\n>>> # Another example of form-encoded data\n>>> page = await AsyncFetcher.post('https://example.com/submit', data={'username': 'user', 'password': 'pass'}, http3=True)\n>>> # JSON data\n>>> page = await AsyncFetcher.post('https://example.com/api', json={'key': 'value'})\n```\n#### PUT\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> # Basic PUT\n>>> page = Fetcher.put('https://example.com/update', data={'status': 'updated'})\n>>> page = Fetcher.put('https://example.com/update', data={'status': 'updated'}, stealthy_headers=True, follow_redirects=True, impersonate=\"chrome\")\n>>> page = Fetcher.put('https://example.com/update', data={'status': 'updated'}, proxy='http://username:password@localhost:8030')\n>>> # Another example of form-encoded data\n>>> page = Fetcher.put(\"https://scrapling.requestcatcher.com/put\", data={'key': ['value1', 'value2']})\n```\nAnd for asynchronous requests, it's a small adjustment\n```python\n>>> from scrapling.fetchers import AsyncFetcher\n>>> # Basic PUT\n>>> page = await AsyncFetcher.put('https://example.com/update', data={'status': 'updated'})\n>>> page = await AsyncFetcher.put('https://example.com/update', data={'status': 'updated'}, stealthy_headers=True, follow_redirects=True, impersonate=\"chrome\")\n>>> page = await AsyncFetcher.put('https://example.com/update', data={'status': 'updated'}, proxy='http://username:password@localhost:8030')\n>>> # Another example of form-encoded data\n>>> page = await AsyncFetcher.put(\"https://scrapling.requestcatcher.com/put\", data={'key': ['value1', 'value2']})\n```\n\n#### DELETE\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> page = Fetcher.delete('https://example.com/resource/123')\n>>> page = Fetcher.delete('https://example.com/resource/123', stealthy_headers=True, follow_redirects=True, impersonate=\"chrome\")\n>>> page = Fetcher.delete('https://example.com/resource/123', proxy='http://username:password@localhost:8030')\n```\nAnd for asynchronous requests, it's a small adjustment\n```python\n>>> from scrapling.fetchers import AsyncFetcher\n>>> page = await AsyncFetcher.delete('https://example.com/resource/123')\n>>> page = await AsyncFetcher.delete('https://example.com/resource/123', stealthy_headers=True, follow_redirects=True, impersonate=\"chrome\")\n>>> page = await AsyncFetcher.delete('https://example.com/resource/123', proxy='http://username:password@localhost:8030')\n```\n\n## Session Management\n\nFor making multiple requests with the same configuration, use the `FetcherSession` class. It can be used in both synchronous and asynchronous code without issue; the class automatically detects and changes the session type, without requiring a different import.\n\nThe `FetcherSession` class can accept nearly all the arguments that the methods can take, which enables you to specify a config for the entire session and later choose a different config for one of the requests effortlessly, as you will see in the following examples.\n\n```python\nfrom scrapling.fetchers import FetcherSession\n\n# Create a session with default configuration\nwith FetcherSession(\n impersonate='chrome',\n http3=True,\n stealthy_headers=True,\n timeout=30,\n retries=3\n) as session:\n # Make multiple requests with the same settings and the same cookies\n page1 = session.get('https://scrapling.requestcatcher.com/get')\n page2 = session.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'})\n page3 = session.get('https://api.github.com/events')\n\n # All requests share the same session and connection pool\n```\n\nYou can also use a `ProxyRotator` with `FetcherSession` for automatic proxy rotation across requests:\n\n```python\nfrom scrapling.fetchers import FetcherSession, ProxyRotator\n\nrotator = ProxyRotator([\n 'http://proxy1:8080',\n 'http://proxy2:8080',\n 'http://proxy3:8080',\n])\n\nwith FetcherSession(proxy_rotator=rotator, impersonate='chrome') as session:\n # Each request automatically uses the next proxy in rotation\n page1 = session.get('https://example.com/page1')\n page2 = session.get('https://example.com/page2')\n\n # You can check which proxy was used via the response metadata\n print(page1.meta['proxy'])\n```\n\nYou can also override the session proxy (or rotator) for a specific request by passing `proxy=` directly to the request method:\n\n```python\nwith FetcherSession(proxy='http://default-proxy:8080') as session:\n # Uses the session proxy\n page1 = session.get('https://example.com/page1')\n\n # Override the proxy for this specific request\n page2 = session.get('https://example.com/page2', proxy='http://special-proxy:9090')\n```\n\nAnd here's an async example\n\n```python\nasync with FetcherSession(impersonate='firefox', http3=True) as session:\n # All standard HTTP methods available\n response = await session.get('https://example.com')\n response = await session.post('https://scrapling.requestcatcher.com/post', json={'data': 'value'})\n response = await session.put('https://scrapling.requestcatcher.com/put', data={'update': 'info'})\n response = await session.delete('https://scrapling.requestcatcher.com/delete')\n```\nor better\n```python\nimport asyncio\nfrom scrapling.fetchers import FetcherSession\n\n# Async session usage\nasync with FetcherSession(impersonate=\"safari\") as session:\n urls = ['https://example.com/page1', 'https://example.com/page2']\n\n tasks = [\n session.get(url) for url in urls\n ]\n\n pages = await asyncio.gather(*tasks)\n```\n\nThe `Fetcher` class uses `FetcherSession` to create a temporary session with each request you make.\n\n### Session Benefits\n\n- **A lot faster**: 10 times faster than creating a single session for each request\n- **Cookie persistence**: Automatic cookie handling across requests\n- **Resource efficiency**: Better memory and CPU usage for multiple requests\n- **Centralized configuration**: Single place to manage request settings\n\n## Examples\nSome well-rounded examples to aid newcomers to Web Scraping\n\n### Basic HTTP Request\n\n```python\nfrom scrapling.fetchers import Fetcher\n\n# Make a request\npage = Fetcher.get('https://example.com')\n\n# Check the status\nif page.status == 200:\n # Extract title\n title = page.css('title::text').get()\n print(f\"Page title: {title}\")\n\n # Extract all links\n links = page.css('a::attr(href)').getall()\n print(f\"Found {len(links)} links\")\n```\n\n### Product Scraping\n\n```python\nfrom scrapling.fetchers import Fetcher\n\ndef scrape_products():\n page = Fetcher.get('https://example.com/products')\n \n # Find all product elements\n products = page.css('.product')\n \n results = []\n for product in products:\n results.append({\n 'title': product.css('.title::text').get(),\n 'price': product.css('.price::text').re_first(r'\\d+\\.\\d{2}'),\n 'description': product.css('.description::text').get(),\n 'in_stock': product.has_class('in-stock')\n })\n \n return results\n```\n\n### Downloading Files\n\n```python\nfrom scrapling.fetchers import Fetcher\n\npage = Fetcher.get('https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/main_cover.png')\nwith open(file='main_cover.png', mode='wb') as f:\n f.write(page.body)\n```\n\n### Pagination Handling\n\n```python\nfrom scrapling.fetchers import Fetcher\n\ndef scrape_all_pages():\n base_url = 'https://example.com/products?page={}'\n page_num = 1\n all_products = []\n \n while True:\n # Get current page\n page = Fetcher.get(base_url.format(page_num))\n \n # Find products\n products = page.css('.product')\n if not products:\n break\n \n # Process products\n for product in products:\n all_products.append({\n 'name': product.css('.name::text').get(),\n 'price': product.css('.price::text').get()\n })\n \n # Next page\n page_num += 1\n \n return all_products\n```\n\n### Form Submission\n\n```python\nfrom scrapling.fetchers import Fetcher\n\n# Submit login form\nresponse = Fetcher.post(\n 'https://example.com/login',\n data={\n 'username': 'user@example.com',\n 'password': 'password123'\n }\n)\n\n# Check login success\nif response.status == 200:\n # Extract user info\n user_name = response.css('.user-name::text').get()\n print(f\"Logged in as: {user_name}\")\n```\n\n### Table Extraction\n\n```python\nfrom scrapling.fetchers import Fetcher\n\ndef extract_table():\n page = Fetcher.get('https://example.com/data')\n \n # Find table\n table = page.css('table')[0]\n \n # Extract headers\n headers = [\n th.text for th in table.css('thead th')\n ]\n \n # Extract rows\n rows = []\n for row in table.css('tbody tr'):\n cells = [td.text for td in row.css('td')]\n rows.append(dict(zip(headers, cells)))\n \n return rows\n```\n\n### Navigation Menu\n\n```python\nfrom scrapling.fetchers import Fetcher\n\ndef extract_menu():\n page = Fetcher.get('https://example.com')\n \n # Find navigation\n nav = page.css('nav')[0]\n \n menu = {}\n for item in nav.css('li'):\n links = item.css('a')\n if links:\n link = links[0]\n menu[link.text] = {\n 'url': link['href'],\n 'has_submenu': bool(item.css('.submenu'))\n }\n \n return menu\n```\n\n## When to Use\n\nUse `Fetcher` when:\n\n- Need rapid HTTP requests.\n- Want minimal overhead.\n- Don't need JavaScript execution (the website can be scraped through requests).\n- Need some stealth features (ex, the targeted website is using protection but doesn't use JavaScript challenges).\n\nUse `FetcherSession` when:\n\n- Making multiple requests to the same or different sites.\n- Need to maintain cookies/authentication between requests.\n- Want connection pooling for better performance.\n- Require consistent configuration across requests.\n- Working with APIs that require a session state.\n\nUse other fetchers when:\n\n- Need browser automation.\n- Need advanced anti-bot/stealth capabilities.\n- Need JavaScript support or interacting with dynamic content" }, { "path": "docs/fetching/stealthy.md", "content": "# Fetching dynamic websites with hard protections\n\nHere, we will discuss the `StealthyFetcher` class. This class is very similar to the [DynamicFetcher](dynamic.md#introduction) class, including the browsers, the automation, and the use of [Playwright's API](https://playwright.dev/python/docs/intro). The main difference is that this class provides advanced anti-bot protection bypass capabilities; most of them are handled automatically under the hood, and the rest is up to you to enable.\n\nAs with [DynamicFetcher](dynamic.md#introduction), you will need some knowledge about [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) to automate the page, as we will explain later.\n\n!!! success \"Prerequisites\"\n\n 1. You've completed or read the [DynamicFetcher](dynamic.md#introduction) page since this class builds upon it, and we won't repeat the same information here for that reason.\n 2. You've completed or read the [Fetchers basics](../fetching/choosing.md) page to understand what the [Response object](../fetching/choosing.md#response-object) is and which fetcher to use.\n 3. You've completed or read the [Querying elements](../parsing/selection.md) page to understand how to find/extract elements from the [Selector](../parsing/main_classes.md#selector)/[Response](../fetching/choosing.md#response-object) object.\n 4. You've completed or read the [Main classes](../parsing/main_classes.md) page to know what properties/methods the [Response](../fetching/choosing.md#response-object) class is inheriting from the [Selector](../parsing/main_classes.md#selector) class.\n\n## Basic Usage\nYou have one primary way to import this Fetcher, which is the same for all fetchers.\n\n```python\n>>> from scrapling.fetchers import StealthyFetcher\n```\nCheck out how to configure the parsing options [here](choosing.md#parser-configuration-in-all-fetchers)\n\n!!! abstract\n\n The async version of the `fetch` method is `async_fetch`, of course.\n\n## What does it do?\n\nThe `StealthyFetcher` class is a stealthy version of the [DynamicFetcher](dynamic.md#introduction) class, and here are some of the things it does:\n\n1. It easily bypasses all types of Cloudflare's Turnstile/Interstitial automatically. \n2. It bypasses CDP runtime leaks and WebRTC leaks.\n3. It isolates JS execution, removes many Playwright fingerprints, and stops detection through some of the known behaviors that bots do.\n4. It generates canvas noise to prevent fingerprinting through canvas.\n5. It automatically patches known methods to detect running in headless mode and provides an option to defeat timezone mismatch attacks.\n6. and other anti-protection options...\n\n## Full list of arguments\nScrapling provides many options with this fetcher and its session classes. Before jumping to the [examples](#examples), here's the full list of arguments\n\n\n| Argument | Description | Optional |\n|:-------------------:|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:--------:|\n| url | Target url | โŒ |\n| headless | Pass `True` to run the browser in headless/hidden (**default**) or `False` for headful/visible mode. | โœ”๏ธ |\n| disable_resources | Drop requests for unnecessary resources for a speed boost. Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`. | โœ”๏ธ |\n| cookies | Set cookies for the next request. | โœ”๏ธ |\n| useragent | Pass a useragent string to be used. **Otherwise, the fetcher will generate and use a real Useragent of the same browser and version.** | โœ”๏ธ |\n| network_idle | Wait for the page until there are no network connections for at least 500 ms. | โœ”๏ธ |\n| load_dom | Enabled by default, wait for all JavaScript on page(s) to fully load and execute (wait for the `domcontentloaded` state). | โœ”๏ธ |\n| timeout | The timeout (milliseconds) used in all operations and waits through the page. The default is 30,000 ms (30 seconds). | โœ”๏ธ |\n| wait | The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the `Response` object. | โœ”๏ธ |\n| page_action | Added for automation. Pass a function that takes the `page` object and does the necessary automation. | โœ”๏ธ |\n| wait_selector | Wait for a specific css selector to be in a specific state. | โœ”๏ธ |\n| init_script | An absolute path to a JavaScript file to be executed on page creation for all pages in this session. | โœ”๏ธ |\n| wait_selector_state | Scrapling will wait for the given state to be fulfilled for the selector given with `wait_selector`. _Default state is `attached`._ | โœ”๏ธ |\n| google_search | Enabled by default, Scrapling will set a Google referer header. | โœ”๏ธ |\n| extra_headers | A dictionary of extra headers to add to the request. _The referer set by `google_search` takes priority over the referer set here if used together._ | โœ”๏ธ |\n| proxy | The proxy to be used with requests. It can be a string or a dictionary with only the keys 'server', 'username', and 'password'. | โœ”๏ธ |\n| real_chrome | If you have a Chrome browser installed on your device, enable this, and the Fetcher will launch and use an instance of your browser. | โœ”๏ธ |\n| locale | Specify user locale, for example, `en-GB`, `de-DE`, etc. Locale will affect `navigator.language` value, `Accept-Language` request header value, as well as number and date formatting rules. Defaults to the system default locale. | โœ”๏ธ |\n| timezone_id | Changes the timezone of the browser. Defaults to the system timezone. | โœ”๏ธ |\n| cdp_url | Instead of launching a new browser instance, connect to this CDP URL to control real browsers through CDP. | โœ”๏ธ |\n| user_data_dir | Path to a User Data Directory, which stores browser session data like cookies and local storage. The default is to create a temporary directory. **Only Works with sessions** | โœ”๏ธ |\n| extra_flags | A list of additional browser flags to pass to the browser on launch. | โœ”๏ธ |\n| solve_cloudflare | When enabled, fetcher solves all types of Cloudflare's Turnstile/Interstitial challenges before returning the response to you. | โœ”๏ธ |\n| block_webrtc | Forces WebRTC to respect proxy settings to prevent local IP address leak. | โœ”๏ธ |\n| hide_canvas | Add random noise to canvas operations to prevent fingerprinting. | โœ”๏ธ |\n| allow_webgl | Enabled by default. Disabling it disables WebGL and WebGL 2.0 support entirely. Disabling WebGL is not recommended, as many WAFs now check if WebGL is enabled. | โœ”๏ธ |\n| additional_args | Additional arguments to be passed to Playwright's context as additional settings, and they take higher priority than Scrapling's settings. | โœ”๏ธ |\n| selector_config | A dictionary of custom parsing arguments to be used when creating the final `Selector`/`Response` class. | โœ”๏ธ |\n| blocked_domains | A set of domain names to block requests to. Subdomains are also matched (e.g., `\"example.com\"` blocks `\"sub.example.com\"` too). | โœ”๏ธ |\n| proxy_rotator | A `ProxyRotator` instance for automatic proxy rotation. Cannot be combined with `proxy`. | โœ”๏ธ |\n| retries | Number of retry attempts for failed requests. Defaults to 3. | โœ”๏ธ |\n| retry_delay | Seconds to wait between retry attempts. Defaults to 1. | โœ”๏ธ |\n\nIn session classes, all these arguments can be set globally for the session. Still, you can configure each request individually by passing some of the arguments here that can be configured on the browser tab level like: `google_search`, `timeout`, `wait`, `page_action`, `extra_headers`, `disable_resources`, `wait_selector`, `wait_selector_state`, `network_idle`, `load_dom`, `solve_cloudflare`, `blocked_domains`, `proxy`, and `selector_config`.\n\n!!! note \"Notes:\"\n\n 1. It's basically the same arguments as [DynamicFetcher](dynamic.md#introduction) class, but with these additional arguments: `solve_cloudflare`, `block_webrtc`, `hide_canvas`, and `allow_webgl`.\n 2. The `disable_resources` option made requests ~25% faster in my tests for some websites and can help save your proxy usage, but be careful with it, as it can cause some websites to never finish loading.\n 3. The `google_search` argument is enabled by default for all requests, setting the referer to `https://www.google.com/`. If used together with `extra_headers`, it takes priority over the referer set there.\n 4. If you didn't set a user agent and enabled headless mode, the fetcher will generate a real user agent for the same browser version and use it. If you didn't set a user agent and didn't enable headless mode, the fetcher will use the browser's default user agent, which is the same as in standard browsers in the latest versions.\n\n## Examples\nIt's easier to understand with examples, so we will now review most of the arguments individually. Since it's the same class as the [DynamicFetcher](dynamic.md#introduction), you can refer to that page for more examples, as we won't repeat all the examples from there.\n\n### Cloudflare and stealth options\n\n```python\n# Automatic Cloudflare solver\npage = StealthyFetcher.fetch('https://nopecha.com/demo/cloudflare', solve_cloudflare=True)\n\n# Works with other stealth options\npage = StealthyFetcher.fetch(\n 'https://protected-site.com',\n solve_cloudflare=True,\n block_webrtc=True,\n real_chrome=True,\n hide_canvas=True,\n google_search=True,\n proxy='http://username:password@host:port', # It can also be a dictionary with only the keys 'server', 'username', and 'password'.\n)\n```\n\nThe `solve_cloudflare` parameter enables automatic detection and solving all types of Cloudflare's Turnstile/Interstitial challenges:\n\n- JavaScript challenges (managed)\n- Interactive challenges (clicking verification boxes)\n- Invisible challenges (automatic background verification)\n\nAnd even solves the custom pages with embedded captcha.\n\n!!! notes \"**Important notes:**\"\n\n 1. Sometimes, with websites that use custom implementations, you will need to use `wait_selector` to make sure Scrapling waits for the real website content to be loaded after solving the captcha. Some websites can be the real definition of an edge case while we are trying to make the solver as generic as possible.\n 2. The timeout should be at least 60 seconds when using the Cloudflare solver for sufficient challenge-solving time.\n 3. This feature works seamlessly with proxies and other stealth options.\n\n### Browser Automation\nThis is where your knowledge about [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) comes into play. The function you pass here takes the page object from Playwright's API, performs the desired action, and then the fetcher continues.\n\nThis function is executed immediately after waiting for `network_idle` (if enabled) and before waiting for the `wait_selector` argument, allowing it to be used for purposes beyond automation. You can alter the page as you want.\n\nIn the example below, I used the pages' [mouse events](https://playwright.dev/python/docs/api/class-mouse) to scroll the page with the mouse wheel, then move the mouse.\n```python\nfrom playwright.sync_api import Page\n\ndef scroll_page(page: Page):\n page.mouse.wheel(10, 0)\n page.mouse.move(100, 400)\n page.mouse.up()\n\npage = StealthyFetcher.fetch('https://example.com', page_action=scroll_page)\n```\nOf course, if you use the async fetch version, the function must also be async.\n```python\nfrom playwright.async_api import Page\n\nasync def scroll_page(page: Page):\n await page.mouse.wheel(10, 0)\n await page.mouse.move(100, 400)\n await page.mouse.up()\n\npage = await StealthyFetcher.async_fetch('https://example.com', page_action=scroll_page)\n```\n\n### Wait Conditions\n```python\n# Wait for the selector\npage = StealthyFetcher.fetch(\n 'https://example.com',\n wait_selector='h1',\n wait_selector_state='visible'\n)\n```\nThis is the last wait the fetcher will do before returning the response (if enabled). You pass a CSS selector to the `wait_selector` argument, and the fetcher will wait for the state you passed in the `wait_selector_state` argument to be fulfilled. If you didn't pass a state, the default would be `attached`, which means it will wait for the element to be present in the DOM.\n\nAfter that, if `load_dom` is enabled (the default), the fetcher will check again to see if all JavaScript files are loaded and executed (in the `domcontentloaded` state) or continue waiting. If you have enabled `network_idle`, the fetcher will wait for `network_idle` to be fulfilled again, as explained above.\n\nThe states the fetcher can wait for can be any of the following ([source](https://playwright.dev/python/docs/api/class-page#page-wait-for-selector)):\n\n- `attached`: Wait for an element to be present in the DOM.\n- `detached`: Wait for an element to not be present in the DOM.\n- `visible`: wait for an element to have a non-empty bounding box and no `visibility:hidden`. Note that an element without any content or with `display:none` has an empty bounding box and is not considered visible.\n- `hidden`: wait for an element to be either detached from the DOM, or have an empty bounding box, or `visibility:hidden`. This is opposite to the `'visible'` option.\n\n\n### Real-world example (Amazon)\nThis is for educational purposes only; this example was generated by AI, which also shows how easy it is to work with Scrapling through AI\n```python\ndef scrape_amazon_product(url):\n # Use StealthyFetcher to bypass protection\n page = StealthyFetcher.fetch(url)\n\n # Extract product details\n return {\n 'title': page.css('#productTitle::text').get().clean(),\n 'price': page.css('.a-price .a-offscreen::text').get(),\n 'rating': page.css('[data-feature-name=\"averageCustomerReviews\"] .a-popover-trigger .a-color-base::text').get(),\n 'reviews_count': page.css('#acrCustomerReviewText::text').re_first(r'[\\d,]+'),\n 'features': [\n li.get().clean() for li in page.css('#feature-bullets li span::text')\n ],\n 'availability': page.css('#availability')[0].get_all_text(strip=True),\n 'images': [\n img.attrib['src'] for img in page.css('#altImages img')\n ]\n }\n```\n\n## Session Management\n\nTo keep the browser open until you make multiple requests with the same configuration, use `StealthySession`/`AsyncStealthySession` classes. Those classes can accept all the arguments that the `fetch` function can take, which enables you to specify a config for the entire session.\n\n```python\nfrom scrapling.fetchers import StealthySession\n\n# Create a session with default configuration\nwith StealthySession(\n headless=True,\n real_chrome=True,\n block_webrtc=True,\n solve_cloudflare=True\n) as session:\n # Make multiple requests with the same browser instance\n page1 = session.fetch('https://example1.com')\n page2 = session.fetch('https://example2.com') \n page3 = session.fetch('https://nopecha.com/demo/cloudflare')\n \n # All requests reuse the same tab on the same browser instance\n```\n\n### Async Session Usage\n\n```python\nimport asyncio\nfrom scrapling.fetchers import AsyncStealthySession\n\nasync def scrape_multiple_sites():\n async with AsyncStealthySession(\n real_chrome=True,\n block_webrtc=True,\n solve_cloudflare=True,\n timeout=60000, # 60 seconds for Cloudflare challenges\n max_pages=3\n ) as session:\n # Make async requests with shared browser configuration\n pages = await asyncio.gather(\n session.fetch('https://site1.com'),\n session.fetch('https://site2.com'), \n session.fetch('https://protected-site.com')\n )\n return pages\n```\n\nYou may have noticed the `max_pages` argument. This is a new argument that enables the fetcher to create a **rotating pool of Browser tabs**. Instead of using a single tab for all your requests, you set a limit on the maximum number of pages that can be displayed at once. With each request, the library will close all tabs that have finished their task and check if the number of the current tabs is lower than the maximum allowed number of pages/tabs, then:\n\n1. If you are within the allowed range, the fetcher will create a new tab for you, and then all is as normal.\n2. Otherwise, it will keep checking every subsecond if creating a new tab is allowed or not for 60 seconds, then raise `TimeoutError`. This can happen when the website you are fetching becomes unresponsive.\n\nThis logic allows for multiple URLs to be fetched at the same time in the same browser, which saves a lot of resources, but most importantly, is so fast :)\n\nIn versions 0.3 and 0.3.1, the pool was reusing finished tabs to save more resources/time. That logic proved flawed, as it's nearly impossible to protect pages/tabs from contamination by the previous configuration used in the request before this one.\n\n### Session Benefits\n\n- **Browser reuse**: Much faster subsequent requests by reusing the same browser instance.\n- **Cookie persistence**: Automatic cookie and session state handling as any browser does automatically.\n- **Consistent fingerprint**: Same browser fingerprint across all requests.\n- **Memory efficiency**: Better resource usage compared to launching new browsers with each fetch.\n\n## Using Camoufox as an engine\n\nThis fetcher used a custom version of [Camoufox](https://github.com/daijro/camoufox) as an engine before version 0.3.13, which was replaced by [patchright](https://github.com/Kaliiiiiiiiii-Vinyzu/patchright) for many reasons. If you see that Camoufox is stable on your device, has no high memory issues, and you want to continue using it, then you can.\n\nFirst, you will need to install the Camoufox library, browser, and Firefox system dependencies if you didn't already:\n```commandline\npip install camoufox\nplaywright install-deps firefox\ncamoufox fetch\n```\nThen you will inherit from `StealthySession` and set it as below:\n```python\nfrom scrapling.fetchers import StealthySession\nfrom playwright.sync_api import sync_playwright\nfrom camoufox.utils import launch_options as generate_launch_options\n\nclass StealthySession(StealthySession):\n def start(self):\n \"\"\"Create a browser for this instance and context.\"\"\"\n if not self.playwright:\n self.playwright = sync_playwright().start()\n # Configure camoufox run options here\n launch_options = generate_launch_options(**{\"headless\": True, \"user_data_dir\": ''})\n # Here's an example, part of what we have been doing before v0.3.13\n launch_options = generate_launch_options(**{\n \"geoip\": False,\n \"proxy\": self._config.proxy,\n \"headless\": self._config.headless,\n \"humanize\": True if self._config.solve_cloudflare else False, # Better enable humanize for Cloudflare, otherwise it's up to you\n \"i_know_what_im_doing\": True, # To turn warnings off with the user configurations\n \"allow_webgl\": self._config.allow_webgl,\n \"block_webrtc\": self._config.block_webrtc,\n \"os\": None,\n \"user_data_dir\": self._config.user_data_dir,\n \"firefox_user_prefs\": {\n # This is what enabling `enable_cache` does internally, so we do it from here instead\n \"browser.sessionhistory.max_entries\": 10,\n \"browser.sessionhistory.max_total_viewers\": -1,\n \"browser.cache.memory.enable\": True,\n \"browser.cache.disk_cache_ssl\": True,\n \"browser.cache.disk.smart_size.enabled\": True,\n },\n # etc...\n })\n self.context = self.playwright.firefox.launch_persistent_context(**launch_options)\n else:\n raise RuntimeError(\"Session has been already started\")\n```\nAfter that, you can use it normally as before, even for solving Cloudflare challenges:\n```python\nwith StealthySession(solve_cloudflare=True, headless=True) as session:\n page = session.fetch('https://sergiodemo.com/security/challenge/legacy-challenge')\n if page.css('#page-not-found-404'):\n print('Cloudflare challenge solved successfully!')\n```\n\nThe same logic applies to the `AsyncStealthySession` class with a few differences:\n```python\nfrom scrapling.fetchers import AsyncStealthySession\nfrom playwright.async_api import async_playwright\nfrom camoufox.utils import launch_options as generate_launch_options\n\nclass AsyncStealthySession(AsyncStealthySession):\n async def start(self):\n \"\"\"Create a browser for this instance and context.\"\"\"\n if not self.playwright:\n self.playwright = await async_playwright().start()\n # Configure camoufox run options here\n launch_options = generate_launch_options(**{\"headless\": True, \"user_data_dir\": ''})\n # or set the launch options as in the above example\n self.context = await self.playwright.firefox.launch_persistent_context(**launch_options)\n else:\n raise RuntimeError(\"Session has been already started\")\n \nasync with AsyncStealthySession(solve_cloudflare=True, headless=True) as session:\n page = await session.fetch('https://sergiodemo.com/security/challenge/legacy-challenge')\n if page.css('#page-not-found-404'):\n print('Cloudflare challenge solved successfully!')\n```\n\nEnjoy! :)\n\n## When to Use\n\nUse StealthyFetcher when:\n\n- Bypassing anti-bot protection\n- Need a reliable browser fingerprint\n- Full JavaScript support needed\n- Want automatic stealth features\n- Need browser automation\n- Dealing with Cloudflare protection" }, { "path": "docs/index.md", "content": "<style>\n.md-typeset h1 {\n display: none;\n}\n[data-md-color-scheme=\"default\"] .only-dark { display: none; }\n[data-md-color-scheme=\"slate\"] .only-light { display: none; }\n</style>\n\n<br/>\n<div align=\"center\">\n <a href=\"https://scrapling.readthedocs.io/en/latest/\" alt=\"poster\">\n <img alt=\"Scrapling\" src=\"assets/cover_light.svg\" class=\"only-light\">\n <img alt=\"Scrapling\" src=\"assets/cover_dark.svg\" class=\"only-dark\">\n </a>\n</div>\n\n<h2 align=\"center\"><i>Effortless Web Scraping for the Modern Web</i></h2><br>\n\nScrapling is an adaptive Web Scraping framework that handles everything from a single request to a full-scale crawl.\n\nIts parser learns from website changes and automatically relocates your elements when pages update. Its fetchers bypass anti-bot systems like Cloudflare Turnstile out of the box. And its spider framework lets you scale up to concurrent, multi-session crawls with pause/resume and automatic proxy rotation โ€” all in a few lines of Python. One library, zero compromises.\n\nBlazing fast crawls with real-time stats and streaming. Built by Web Scrapers for Web Scrapers and regular users, there's something for everyone.\n\n```python\nfrom scrapling.fetchers import Fetcher, StealthyFetcher, DynamicFetcher\nStealthyFetcher.adaptive = True\npage = StealthyFetcher.fetch('https://example.com', headless=True, network_idle=True) # Fetch website under the radar!\nproducts = page.css('.product', auto_save=True) # Scrape data that survives website design changes!\nproducts = page.css('.product', adaptive=True) # Later, if the website structure changes, pass `adaptive=True` to find them!\n```\nOr scale up to full crawls\n```python\nfrom scrapling.spiders import Spider, Response\n\nclass MySpider(Spider):\n name = \"demo\"\n start_urls = [\"https://example.com/\"]\n\n async def parse(self, response: Response):\n for item in response.css('.product'):\n yield {\"title\": item.css('h2::text').get()}\n\nMySpider().start()\n```\n\n## Top Sponsors \n\n<style>\n.ad {\n width:240px;\n height:100px;\n}\n\n</style>\n\n<!-- sponsors -->\n<div style=\"text-align: center;\">\n <a href=\"https://hypersolutions.co/?utm_source=github&utm_medium=readme&utm_campaign=scrapling\" target=\"_blank\" title=\"Bot Protection Bypass API for Akamai, DataDome, Incapsula & Kasada\">\n <img src=\"https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/HyperSolutions.png\" class=\"ad\">\n </a>\n <a href=\"https://birdproxies.com/t/scrapling\" target=\"_blank\" title=\"At Bird Proxies, we eliminate your pains such as banned IPs, geo restriction, and high costs so you can focus on your work.\">\n <img src=\"https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/BirdProxies.jpg\" class=\"ad\">\n </a>\n <a href=\"https://evomi.com?utm_source=github&utm_medium=banner&utm_campaign=d4vinci-scrapling\" target=\"_blank\" title=\"Evomi is your Swiss Quality Proxy Provider, starting at $0.49/GB\">\n <img src=\"https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/evomi.png\" class=\"ad\">\n </a>\n <a href=\"https://tikhub.io/?ref=KarimShoair\" target=\"_blank\" title=\"Unlock the Power of Social Media Data & AI\">\n <img src=\"https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/TikHub.jpg\" class=\"ad\">\n </a>\n <a href=\"https://www.nsocks.com/?keyword=2p67aivg\" target=\"_blank\" title=\"Scalable Web Data Access for AI Applications\">\n <img src=\"https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/nsocks.png\" class=\"ad\">\n </a>\n <a href=\"https://petrosky.io/d4vinci\" target=\"_blank\" title=\"PetroSky delivers cutting-edge VPS hosting.\">\n <img src=\"https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/petrosky.png\" class=\"ad\">\n </a>\n <a href=\"https://substack.thewebscraping.club/p/scrapling-hands-on-guide?utm_source=github&utm_medium=repo&utm_campaign=scrapling\" target=\"_blank\" title=\"The #1 newsletter dedicated to Web Scraping\">\n <img src=\"https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/TWSC.png\" class=\"ad\">\n </a>\n <a href=\"https://proxy-seller.com/?partner=CU9CAA5TBYFFT2\" target=\"_blank\" title=\"Proxy-Seller provides reliable proxy infrastructure for Web Scraping\">\n <img src=\"https://raw.githubusercontent.com/D4Vinci/Scrapling/main/images/ProxySeller.png\" class=\"ad\">\n </a>\n <br />\n <br />\n</div>\n<!-- /sponsors -->\n\n<i><sub>Do you want to show your ad here?

all you need to do is pass a function that takes a `Selector` object as an argument and returns `True` if the condition is satisfied or `False` otherwise, like below:\n```python\n>>> section_element.find_ancestor(lambda ancestor: ancestor.css('nav'))\n<data='<body> <header><nav><ul><li> <a href=\"#h...' parent='<html><head><title>Complex Web Page</tit...'>\n```\n\n## Fetching websites\nInstead of passing the raw HTML to Scrapling, you can retrieve a website's response directly via HTTP requests or by fetching it in a browser.\n\nA fetcher is made for every use case.\n\n### HTTP Requests\nFor simple HTTP requests, there's a `Fetcher` class that can be imported and used as below:\n```python\nfrom scrapling.fetchers import Fetcher\npage = Fetcher.get('https://scrapling.requestcatcher.com/get', impersonate=\"chrome\")\n```\nWith that out of the way, here's how to do all HTTP methods:\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> page = Fetcher.get('https://scrapling.requestcatcher.com/get', stealthy_headers=True, follow_redirects=True)\n>>> page = Fetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030')\n>>> page = Fetcher.put('https://scrapling.requestcatcher.com/put', data={'key': 'value'})\n>>> page = Fetcher.delete('https://scrapling.requestcatcher.com/delete')\n```\nFor Async requests, you will replace the import like below:\n```python\n>>> from scrapling.fetchers import AsyncFetcher\n>>> page = await AsyncFetcher.get('https://scrapling.requestcatcher.com/get', stealthy_headers=True, follow_redirects=True)\n>>> page = await AsyncFetcher.post('https://scrapling.requestcatcher.com/post', data={'key': 'value'}, proxy='http://username:password@localhost:8030')\n>>> page = await AsyncFetcher.put('https://scrapling.requestcatcher.com/put', data={'key': 'value'})\n>>> page = await AsyncFetcher.delete('https://scrapling.requestcatcher.com/delete')\n```\n\n!!! note \"Notes:\"\n\n 1. You have the `stealthy_headers` argument, which, when enabled, makes requests to generate real browser headers and use them, including a Google referer header. It's enabled by default.\n 2. The `impersonate` argument lets you fake the TLS fingerprint for a specific browser version.\n 3. There's also the `http3` argument, which, when enabled, makes the fetcher use HTTP/3 for requests, which makes your requests more authentic\n\nThis is just the tip of the iceberg with this fetcher; check out the rest from [here](fetching/static.md)\n\n### Dynamic loading\nWe have you covered if you deal with dynamic websites like most today!\n\nThe `DynamicFetcher` class (formerly `PlayWrightFetcher`) offers many options for fetching and loading web pages using Chromium-based browsers.\n```python\n>>> from scrapling.fetchers import DynamicFetcher\n>>> page = DynamicFetcher.fetch('https://www.google.com/search?q=%22Scrapling%22', disable_resources=True) # Vanilla Playwright option\n>>> page.css(\"#search a::attr(href)\").get()\n'https://github.com/D4Vinci/Scrapling'\n>>> # The async version of fetch\n>>> page = await DynamicFetcher.async_fetch('https://www.google.com/search?q=%22Scrapling%22', disable_resources=True)\n>>> page.css(\"#search a::attr(href)\").get()\n'https://github.com/D4Vinci/Scrapling'\n```\nIt's built on top of [Playwright](https://playwright.dev/python/), and it's currently providing two main run options that can be mixed as you want:\n\n- Vanilla Playwright without any modifications other than the ones you chose. It uses the Chromium browser.\n- Real browsers like your Chrome browser by passing the `real_chrome` argument or the CDP URL of your browser to be controlled by the Fetcher, and most of the options can be enabled on it.\n\n\nAgain, this is just the tip of the iceberg with this fetcher. Check out the rest from [here](fetching/dynamic.md) for all details and the complete list of arguments.\n\n### Dynamic anti-protection loading\nWe also have you covered if you deal with dynamic websites with annoying anti-protections!\n\nThe `StealthyFetcher` class uses a stealthy version of the `DynamicFetcher` explained above. \n\nSome of the things it does:\n\n1. It easily bypasses all types of Cloudflare's Turnstile/Interstitial automatically. \n2. It bypasses CDP runtime leaks and WebRTC leaks.\n3. It isolates JS execution, removes many Playwright fingerprints, and stops detection through some of the known behaviors that bots do.\n4. It generates canvas noise to prevent fingerprinting through canvas.\n5. It automatically patches known methods to detect running in headless mode and provides an option to defeat timezone mismatch attacks.\n6. and other anti-protection options...\n\n```python\n>>> from scrapling.fetchers import StealthyFetcher\n>>> page = StealthyFetcher.fetch('https://www.browserscan.net/bot-detection') # Running headless by default\n>>> page.status == 200\nTrue\n>>> page = StealthyFetcher.fetch('https://nopecha.com/demo/cloudflare', solve_cloudflare=True) # Solve Cloudflare captcha automatically if presented\n>>> page.status == 200\nTrue\n>>> page = StealthyFetcher.fetch('https://www.browserscan.net/bot-detection', humanize=True, os_randomize=True) # and the rest of arguments...\n>>> # The async version of fetch\n>>> page = await StealthyFetcher.async_fetch('https://www.browserscan.net/bot-detection')\n>>> page.status == 200\nTrue\n```\n\nAgain, this is just the tip of the iceberg with this fetcher. Check out the rest from [here](fetching/stealthy.md) for all details and the complete list of arguments.\n\n---\n\nThat's Scrapling at a glance. If you want to learn more, continue to the next section." }, { "path": "docs/parsing/adaptive.md", "content": "# Adaptive scraping\n\n!!! success \"Prerequisites\"\n\n 1. You've completed or read the [Querying elements](../parsing/selection.md) page to understand how to find/extract elements from the [Selector](../parsing/main_classes.md#selector) object.\n 2. You've completed or read the [Main classes](../parsing/main_classes.md) page to understand the [Selector](../parsing/main_classes.md#selector) class.\n\nAdaptive scraping (previously known as automatch) is one of Scrapling's most powerful features. It allows your scraper to survive website changes by intelligently tracking and relocating elements.\n\nLet's say you are scraping a page with a structure like this:\n```html\n<div class=\"container\">\n <section class=\"products\">\n <article class=\"product\" id=\"p1\">\n <h3>Product 1</h3>\n <p class=\"description\">Description 1</p>\n </article>\n <article class=\"product\" id=\"p2\">\n <h3>Product 2</h3>\n <p class=\"description\">Description 2</p>\n </article>\n </section>\n</div>\n```\nAnd you want to scrape the first product, the one with the `p1` ID. You will probably write a selector like this\n```python\npage.css('#p1')\n```\nWhen website owners implement structural changes like\n```html\n<div class=\"new-container\">\n <div class=\"product-wrapper\">\n <section class=\"products\">\n <article class=\"product new-class\" data-id=\"p1\">\n <div class=\"product-info\">\n <h3>Product 1</h3>\n <p class=\"new-description\">Description 1</p>\n </div>\n </article>\n <article class=\"product new-class\" data-id=\"p2\">\n <div class=\"product-info\">\n <h3>Product 2</h3>\n <p class=\"new-description\">Description 2</p>\n </div>\n </article>\n </section>\n </div>\n</div>\n```\nThe selector will no longer function, and your code needs maintenance. That's where Scrapling's `adaptive` feature comes into play.\n\nWith Scrapling, you can enable the `adaptive` feature the first time you select an element, and the next time you select that element and it doesn't exist, Scrapling will remember its properties and search on the website for the element with the highest percentage of similarity to that element, and without AI :)\n\n```python\nfrom scrapling import Selector, Fetcher\n# Before the change\npage = Selector(page_source, adaptive=True, url='example.com')\n# or\nFetcher.adaptive = True\npage = Fetcher.get('https://example.com')\n# then\nelement = page.css('#p1', auto_save=True)\nif not element: # One day website changes?\n element = page.css('#p1', adaptive=True) # Scrapling still finds it!\n# the rest of your code...\n```\nBelow, I will show you an example of how to use this feature. Then, we will dive deep into how to use it and provide details about this feature. Note that it works with all selection methods, not just CSS/XPATH selection.\n\n## Real-World Scenario\nLet's use a real website as an example and use one of the fetchers to fetch its source. To achieve this, we need to identify a website that is about to update its design/structure, copy its source, and then wait for the website to change. Of course, that's nearly impossible to know unless I know the website's owner, but that will make it a staged test, haha.\n\nTo solve this issue, I will use [The Web Archive](https://archive.org/)'s [Wayback Machine](https://web.archive.org/). Here is a copy of [StackOverFlow's website in 2010](https://web.archive.org/web/20100102003420/http://stackoverflow.com/); pretty old, eh?</br>Let's see if the adaptive feature can extract the same button in the old design from 2010 and the current design using the same selector :)\n\nIf I want to extract the Questions button from the old design, I can use a selector like this: `#hmenus > div:nth-child(1) > ul > li:nth-child(1) > a`. This selector is too specific because it was generated by Google Chrome.\n\n\nNow, let's test the same selector in both versions\n```python\n>> from scrapling import Fetcher\n>> selector = '#hmenus > div:nth-child(1) > ul > li:nth-child(1) > a'\n>> old_url = \"https://web.archive.org/web/20100102003420/http://stackoverflow.com/\"\n>> new_url = \"https://stackoverflow.com/\"\n>> Fetcher.configure(adaptive = True, adaptive_domain='stackoverflow.com')\n>> \n>> page = Fetcher.get(old_url, timeout=30)\n>> element1 = page.css(selector, auto_save=True)[0]\n>> \n>> # Same selector but used in the updated website\n>> page = Fetcher.get(new_url)\n>> element2 = page.css(selector, adaptive=True)[0]\n>> \n>> if element1.text == element2.text:\n... print('Scrapling found the same element in the old and new designs!')\n'Scrapling found the same element in the old and new designs!'\n```\nNote that I introduced a new argument called `adaptive_domain`. This is because, for Scrapling, these are two different domains (`archive.org` and `stackoverflow.com`), so Scrapling will isolate their `adaptive` data. To inform Scrapling that they are the same website, we must pass the custom domain we wish to use while saving `adaptive` data for both, ensuring Scrapling doesn't isolate them.\n\nThe code will be the same in a real-world scenario, except it will use the same URL for both requests, so you won't need to use the `adaptive_domain` argument. This is the closest example I can give to real-world cases, so I hope it didn't confuse you :)\n\nHence, in the two examples above, I used both the `Selector` and `Fetcher` classes to show that the adaptive logic is the same.\n\n!!! info\n\n The main reason for creating the `adaptive_domain` argument was to handle if the website changed its URL while changing the design/structure. In that case, you can use it to continue using the previously stored adaptive data for the new URL. Otherwise, scrapling will consider it a new website and discard the old data.\n\n## How the adaptive scraping feature works\nAdaptive scraping works in two phases:\n\n1. **Save Phase**: Store unique properties of elements\n2. **Match Phase**: Find elements with similar properties later\n\nLet's say you've selected an element through any method and want the library to find it the next time you scrape this website, even if it undergoes structural/design changes. \n\nWith as few technical details as possible, the general logic goes as follows:\n\n 1. You tell Scrapling to save that element's unique properties in one of the ways we will show below.\n 2. Scrapling uses its configured database (SQLite by default) and saves each element's unique properties.\n 3. Now, because everything about the element can be changed or removed by the website's owner(s), nothing from the element can be used as a unique identifier for the database. To solve this issue, I made the storage system rely on two things:\n 1. The domain of the current website. If you are using the `Selector` class, pass it when initializing; if you are using a fetcher, the domain will be automatically taken from the URL.\n 2. An `identifier` to query that element's properties from the database. You don't always have to set the identifier yourself; we'll discuss this later.\n\n Together, they will later be used to retrieve the element's unique properties from the database.\n\n 4. Later, when the website's structure changes, you tell Scrapling to find the element by enabling `adaptive`. Scrapling retrieves the element's unique properties and matches all elements on the page against the unique properties we already have for this element. A score is calculated based on their similarity to the desired element. In that comparison, everything is taken into consideration, as you will see later \n 5. The element(s) with the highest similarity score to the wanted element are returned.\n\n### The unique properties\nYou might wonder what unique properties we are referring to when discussing the removal or alteration of all element properties.\n\nFor Scrapling, the unique elements we are relying on are:\n\n- Element tag name, text, attributes (names and values), siblings (tag names only), and path (tag names only).\n- Element's parent tag name, attributes (names and values), and text.\n\nBut you need to understand that the comparison between elements isn't exact; it's more about how similar these values are. So everything is considered, even the values' order, like the order in which the element class names were written before and the order in which the same element class names are written now.\n\n## How to use adaptive feature\nThe adaptive feature can be applied to any found element, and it's added as arguments to CSS/XPath Selection methods, as you saw above, but we will get back to that later.\n\nFirst, you must enable the `adaptive` feature by passing `adaptive=True` to the [Selector](main_classes.md#selector) class when you initialize it or enable it in the fetcher you are using of the available fetchers, as we will show.\n\nExamples:\n```python\n>>> from scrapling import Selector, Fetcher\n>>> page = Selector(html_doc, adaptive=True)\n# OR\n>>> Fetcher.adaptive = True\n>>> page = Fetcher.get('https://example.com')\n```\nIf you are using the [Selector](main_classes.md#selector) class, you need to pass the url of the website you are using with the argument `url` so Scrapling can separate the properties saved for each element by domain.\n\nIf you didn't pass a URL, the word `default` will be used in place of the URL field while saving the element's unique properties. So, this will only be an issue if you use the same identifier later for a different website and don't pass the URL parameter when initializing it. The save process overwrites previous data, and the `adaptive` feature uses only the latest saved properties.\n\nBesides those arguments, we have `storage` and `storage_args`. Both are for the class to connect to the database; by default, it uses the SQLite class provided by the library. Those arguments shouldn't matter unless you want to write your own storage system, which we will cover on a [separate page in the development section](../development/adaptive_storage_system.md).\n\nNow that you've enabled the `adaptive` feature globally, you have two main ways to use it.\n\n### The CSS/XPath Selection way\nAs you have seen in the example above, first, you have to use the `auto_save` argument while selecting an element that exists on the page, like below\n```python\nelement = page.css('#p1', auto_save=True)\n```\nAnd when the element doesn't exist, you can use the same selector and the `adaptive` argument, and the library will find it for you\n```python\nelement = page.css('#p1', adaptive=True)\n```\nPretty simple, eh?\n\nWell, a lot happened under the hood here. Remember the identifier we mentioned before that you need to set to retrieve the element you want? Here, with the `css`/`xpath` methods, the identifier is set automatically as the selector you passed here to make things easier :)\n\nAdditionally, for all these methods, you can pass the `identifier` argument to set it yourself. This is useful in some instances, or you can use it to save properties with the `auto_save` argument.\n\n### The manual way\nYou manually save and retrieve an element, then relocate it, which all happens within the `adaptive` feature, as shown below. This allows you to relocate any element using any method or selection!\n\nFirst, let's say you got an element like this by text:\n```python\n>>> element = page.find_by_text('Tipping the Velvet', first_match=True)\n```\nYou can save its unique properties using the `save` method, as shown below, but you must set the identifier yourself. For this example, I chose `my_special_element` as an identifier, but it's best to use a meaningful identifier in your code for the same reason you use meaningful variable names :)\n```python\n>>> page.save(element, 'my_special_element')\n```\nNow, later, when you want to retrieve it and relocate it inside the page with `adaptive`, it would be like this\n```python\n>>> element_dict = page.retrieve('my_special_element')\n>>> page.relocate(element_dict, selector_type=True)\n[<data='<a href=\"catalogue/tipping-the-velvet_99...' parent='<h3><a href=\"catalogue/tipping-the-velve...'>]\n>>> page.relocate(element_dict, selector_type=True).css('::text').getall()\n['Tipping the Velvet']\n```\nHence, the `retrieve` and `relocate` methods are used.\n\nIf you want to keep it as a `lxml.etree` object, leave the `selector_type` argument\n```python\n>>> page.relocate(element_dict)\n[<Element a at 0x105a2a7b0>]\n```\n\n## Troubleshooting\n\n### No Matches Found\n```python\n# 1. Check if data was saved\nelement_data = page.retrieve('identifier')\nif not element_data:\n print(\"No data saved for this identifier\")\n\n# 2. Try with different identifier\nproducts = page.css('.product', adaptive=True, identifier='old_selector')\n\n# 3. Save again with new identifier\nproducts = page.css('.new-product', auto_save=True, identifier='new_identifier')\n```\n\n### Wrong Elements Matched\n```python\n# Use more specific selectors\nproducts = page.css('.product-list .product', auto_save=True)\n\n# Or save with more context\nproduct = page.find_by_text('Product Name').parent\npage.save(product, 'specific_product')\n```\n\n## Known Issues\nIn the `adaptive` save process, only the unique properties of the first element in the selection results are saved. So if the selector you are using selects different elements on the page in other locations, `adaptive` will return the first element to you only when you relocate it later. This doesn't include combined CSS selectors (Using commas to combine more than one selector, for example), as these selectors are separated and each is executed alone.\n\n## Final thoughts\nExplaining this feature in detail without complications turned out to be challenging. However, still, if there's something left unclear, you can head out to the [discussions section](https://github.com/D4Vinci/Scrapling/discussions), and I will reply to you ASAP, or the Discord server, or reach out to me privately and have a chat :)" }, { "path": "docs/parsing/main_classes.md", "content": "# Parsing main classes\n\n!!! success \"Prerequisites\"\n\n - Youโ€™ve completed or read the [Querying elements](../parsing/selection.md) page to understand how to find/extract elements from the [Selector](../parsing/main_classes.md#selector) object.\n\nAfter exploring the various ways to select elements with Scrapling and its related features, let's take a step back and examine the [Selector](#selector) class in general, as well as other objects, to gain a better understanding of the parsing engine.\n\nThe [Selector](#selector) class is the core parsing engine in Scrapling, providing HTML parsing and element selection capabilities. You can always import it with any of the following imports\n```python\nfrom scrapling import Selector\nfrom scrapling.parser import Selector\n```\nThen use it directly as you already learned in the [overview](../overview.md) page\n```python\npage = Selector(\n '<html>...</html>',\n url='https://example.com'\n)\n\n# Then select elements as you like\nelements = page.css('.product')\n```\nIn Scrapling, the main object you deal with after passing an HTML source or fetching a website is, of course, a [Selector](#selector) object. Any operation you do, like selection, navigation, etc., will return either a [Selector](#selector) object or a [Selectors](#selectors) object, given that the result is element/elements from the page, not text or similar.\n\nIn other words, the main page is a [Selector](#selector) object, and the elements within are [Selector](#selector) objects, and so on. Any text, such as the text content inside elements or the text inside element attributes, is a [TextHandler](#texthandler) object, and the attributes of each element are stored as [AttributesHandler](#attributeshandler). We will return to both objects later, so let's focus on the [Selector](#selector) object.\n\n## Selector\n### Arguments explained\nThe most important one is `content`, it's used to pass the HTML code you want to parse, and it accepts the HTML content as `str` or `bytes`.\n\nOtherwise, you have the arguments `url`, `adaptive`, `storage`, and `storage_args`. All these arguments are settings used with the `adaptive` feature, and they don't make a difference if you are not going to use that feature, so just ignore them for now, and we will explain them in the [adaptive](adaptive.md) feature page.\n\nThen you have the arguments for parsing adjustments or adjusting/manipulating the HTML content while the library is parsing it:\n\n- **encoding**: This is the encoding that will be used while parsing the HTML. The default is `UTF-8`.\n- **keep_comments**: This tells the library whether to keep HTML comments while parsing the page. It's disabled by default because it can cause issues with your scraping in various ways.\n- **keep_cdata**: Same logic as the HTML comments. [cdata](https://stackoverflow.com/questions/7092236/what-is-cdata-in-html) is removed by default for cleaner HTML.\n\nI have intended to ignore the arguments `huge_tree` and `root` to avoid making this page more complicated than needed.\nYou may notice that I'm doing that a lot because it involves advanced features that you don't need to know to use the library. The development section will cover these missing parts if you are very invested.\n\nAfter that, most properties on the main page and its elements are lazily loaded. This means they don't get initialized until you use them like the text content of a page/element, and this is one of the reasons for Scrapling speed :)\n\n### Properties\nYou have already seen much of this on the [overview](../overview.md) page, but don't worry if you didn't. We will review it more thoroughly using more advanced methods/usages. For clarity, the properties for traversal are separated below in the [traversal](#traversal) section.\n\nLet's say we are parsing this HTML page for simplicity:\n```html\n<html>\n <head>\n <title>Some page\n \n \n

\n\n \n \n\n```\nLoad the page directly as shown before:\n```python\nfrom scrapling import Selector\npage = Selector(html_doc)\n```\nGet all text content on the page recursively\n```python\n>>> page.get_all_text()\n'Some page\\n\\n \\n\\n \\nProduct 1\\nThis is product 1\\n$10.99\\nIn stock: 5\\nProduct 2\\nThis is product 2\\n$20.99\\nIn stock: 3\\nProduct 3\\nThis is product 3\\n$15.99\\nOut of stock'\n```\nGet the first article, as explained before; we will use it as an example\n```python\narticle = page.find('article')\n```\nWith the same logic, get all text content on the element recursively\n```python\n>>> article.get_all_text()\n'Product 1\\nThis is product 1\\n$10.99\\nIn stock: 5'\n```\nBut if you try to get the direct text content, it will be empty because it doesn't have direct text in the HTML code above\n```python\n>>> article.text\n''\n```\nThe `get_all_text` method has the following optional arguments:\n\n1. **separator**: All strings collected will be concatenated using this separator. The default is '\\n'.\n2. **strip**: If enabled, strings will be stripped before concatenation. Disabled by default.\n3. **ignore_tags**: A tuple of all tag names you want to ignore in the final results and ignore any elements nested within them. The default is `('script', 'style',)`.\n4. **valid_values**: If enabled, the method will only collect elements with real values, so all elements with empty text content or only whitespaces will be ignored. It's enabled by default\n\nBy the way, the text returned here is not a standard string but a [TextHandler](#texthandler); we will get to this in detail later, so if the text content can be serialized to JSON, use `.json()` on it\n```python\n>>> script = page.find('script')\n>>> script.json()\n{'lastUpdated': '2024-09-22T10:30:00Z', 'totalProducts': 3}\n```\nLet's continue to get the element tag\n```python\n>>> article.tag\n'article'\n```\nIf you use it on the page directly, you will find that you are operating on the root `html` element\n```python\n>>> page.tag\n'html'\n```\nNow, I think I've hammered the (`page`/`element`) idea, so I won't return to it.\n\nGetting the attributes of the element\n```python\n>>> print(article.attrib)\n{'class': 'product', 'data-id': '1'}\n```\nAccess a specific attribute with any of the following\n```python\n>>> article.attrib['class']\n>>> article.attrib.get('class')\n>>> article['class'] # new in v0.3\n```\nCheck if the attributes contain a specific attribute with any of the methods below\n```python\n>>> 'class' in article.attrib\n>>> 'class' in article # new in v0.3\n```\nGet the HTML content of the element\n```python\n>>> article.html_content\n'

Starting from v0.4, when used on a `Response` object from fetchers, `.body` always returns `bytes`.\n```python\n>>> page.body\n'\\n \\n Some page\\n \\n ...'\n```\nTo get all the ancestors in the DOM tree of this element\n```python\n>>> article.path\n[

I recommend you look up these concepts online to better understand them.\n\nIf you are too lazy to search about it, here's a quick explanation to give you a good idea.
\nIn simple words, the `html` element is the root of the website's tree, as every page starts with an `html` element.
\nThis element will be positioned directly above elements such as `head` and `body`. These are considered \"children\" of the `html` element, and the `html` element is considered their \"parent\". The element `body` is a \"sibling\" of the element `head` and vice versa.\n\nAccessing the parent of an element\n```python\n>>> article.parent\n
\n>>> article.parent.tag\n'div'\n```\nYou can chain it as you want, which applies to all similar properties/methods we will review.\n```python\n>>> article.parent.parent.tag\n'body'\n```\nGet the children of an element\n```python\n>>> article.children\n[Product 1' parent='
,\n This is product 1...' parent='
,\n $10.99' parent='
,\n In stock: 5]\n```\nGet all elements underneath an element. It acts as a nested version of the `children` property\n```python\n>>> article.below_elements\n[Product 1' parent='
,\n This is product 1...' parent='
,\n $10.99' parent='
,\n In stock: 5]\n```\nThis element returns the same result as the `children` property because its children don't have children.\n\nAnother example of using the element with the `product-list` class will clear the difference between the `children` property and the `below_elements` property\n```python\n>>> products_list = page.css('.product-list')[0]\n>>> products_list.children\n[,\n ,\n ]\n\n>>> products_list.below_elements\n[,\n Product 1' parent='
,\n This is product 1...' parent='
,\n $10.99' parent='
,\n In stock: 5,\n ,\n...]\n```\nGet the siblings of an element\n```python\n>>> article.siblings\n[,\n ]\n```\nGet the next element of the current element\n```python\n>>> article.next\n\n```\nThe same logic applies to the `previous` property\n```python\n>>> article.previous # It's the first child, so it doesn't have a previous element\n>>> second_article = page.css('.product[data-id=\"2\"]')[0]\n>>> second_article.previous\n\n```\nYou can check easily and pretty fast if an element has a specific class name or not\n```python\n>>> article.has_class('product')\nTrue\n```\nIf your case needs more than the element's parent, you can iterate over the whole ancestors' tree of any element, like the example below\n```python\nfor ancestor in article.iterancestors():\n # do something with it...\n```\nYou can search for a specific ancestor of an element that satisfies a search function; all you need to do is pass a function that takes a [Selector](#selector) object as an argument and return `True` if the condition satisfies or `False` otherwise, like below:\n```python\n>>> article.find_ancestor(lambda ancestor: ancestor.has_class('product-list'))\n
\n\n>>> article.find_ancestor(lambda ancestor: ancestor.css('.product-list')) # Same result, different approach\n
\n```\n## Selectors\nThe class `Selectors` is the \"List\" version of the [Selector](#selector) class. It inherits from the Python standard `List` type, so it shares all `List` properties and methods while adding more methods to make the operations you want to execute on the [Selector](#selector) instances within more straightforward.\n\nIn the [Selector](#selector) class, all methods/properties that should return a group of elements return them as a [Selectors](#selectors) class instance.\n\nStarting with v0.4, all selection methods consistently return [Selector](#selector)/[Selectors](#selectors) objects, even for text nodes and attribute values. Text nodes (selected via `::text`, `/text()`, `::attr()`, `/@attr`) are wrapped in [Selector](#selector) objects. These text node selectors have `tag` set to `\"#text\"`, and their `text` property returns the text value. You can still access the text value directly, and all other properties return empty/default values gracefully.\n\n```python\n>>> page.css('a::text') # -> Selectors (of text node Selectors)\n>>> page.xpath('//a/text()') # -> Selectors\n>>> page.css('a::text').get() # -> TextHandler (the first text value)\n>>> page.css('a::text').getall() # -> TextHandlers (all text values)\n>>> page.css('a::attr(href)') # -> Selectors\n>>> page.xpath('//a/@href') # -> Selectors\n>>> page.css('.price_color') # -> Selectors\n```\n\n### Data extraction methods\nStarting with v0.4, [Selector](#selector) and [Selectors](#selectors) both provide `get()`, `getall()`, and their aliases `extract_first` and `extract` (following Scrapy conventions). The old `get_all()` method has been removed.\n\n**On a [Selector](#selector) object:**\n\n- `get()` returns a `TextHandler` โ€” for text node selectors, it returns the text value; for HTML element selectors, it returns the serialized outer HTML.\n- `getall()` returns a `TextHandlers` list containing the single serialized string.\n- `extract_first` is an alias for `get()`, and `extract` is an alias for `getall()`.\n\n```python\n>>> page.css('h3')[0].get() # Outer HTML of the element\n'

Product 1

'\n\n>>> page.css('h3::text')[0].get() # Text value of the text node\n'Product 1'\n```\n\n**On a [Selectors](#selectors) object:**\n\n- `get(default=None)` returns the serialized string of the **first** element, or `default` if the list is empty.\n- `getall()` serializes **all** elements and returns a `TextHandlers` list.\n- `extract_first` is an alias for `get()`, and `extract` is an alias for `getall()`.\n\n```python\n>>> page.css('.price::text').get() # First price text\n'$10.99'\n\n>>> page.css('.price::text').getall() # All price texts\n['$10.99', '$20.99', '$15.99']\n\n>>> page.css('.price::text').get('') # With default value\n'$10.99'\n```\n\nThese methods work seamlessly with all selection types (CSS, XPath, `find`, etc.) and are the recommended way to extract text and attribute values in a Scrapy-compatible style.\n\nNow, let's see what [Selectors](#selectors) class adds to the table with that out of the way.\n### Properties\nApart from the standard operations on Python lists, such as iteration and slicing.\n\nYou can do the following:\n\nExecute CSS and XPath selectors directly on the [Selector](#selector) instances it has, while the return types are the same as [Selector](#selector)'s `css` and `xpath` methods. The arguments are similar, except the `adaptive` argument is not available here. This, of course, makes chaining methods very straightforward.\n```python\n>>> page.css('.product_pod a')\n[,\n ,\n ,\n ,\n ,\n ,\n...]\n\n>>> page.css('.product_pod').css('a') # Returns the same result\n[,\n ,\n ,\n ,\n ,\n ,\n...]\n```\nRun the `re` and `re_first` methods directly. They take the same arguments passed to the [Selector](#selector) class. I will leave the explanation of these methods to the [TextHandler](#texthandler) section below.\n\nHowever, in this class, the `re_first` behaves differently as it runs `re` on each [Selector](#selector) within and returns the first one with a result. The `re` method will return a [TextHandlers](#texthandlers) object as normal, which combines all the [TextHandler](#texthandler) instances into one [TextHandlers](#texthandlers) instance.\n```python\n>>> page.css('.price_color').re(r'[\\d\\.]+')\n['51.77',\n '53.74',\n '50.10',\n '47.82',\n '54.23',\n...]\n\n>>> page.css('.product_pod h3 a::attr(href)').re(r'catalogue/(.*)/index.html')\n['a-light-in-the-attic_1000',\n 'tipping-the-velvet_999',\n 'soumission_998',\n 'sharp-objects_997',\n...]\n```\nWith the `search` method, you can search quickly in the available [Selector](#selector) instances. The function you pass must accept a [Selector](#selector) instance as the first argument and return True/False. The method will return the first [Selector](#selector) instance that satisfies the function; otherwise, it will return `None`.\n```python\n# Find all the products with price '53.23'.\n>>> search_function = lambda p: float(p.css('.price_color').re_first(r'[\\d\\.]+')) == 54.23\n>>> page.css('.product_pod').search(search_function)\n
\n```\nYou can use the `filter` method, too, which takes a function like the `search` method but returns an `Selectors` instance of all the [Selector](#selector) instances that satisfy the function\n```python\n# Find all products with prices over $50\n>>> filtering_function = lambda p: float(p.css('.price_color').re_first(r'[\\d\\.]+')) > 50\n>>> page.css('.product_pod').filter(filtering_function)\n[
,\n
,\n
,\n...]\n```\nYou can safely access the first or last element without worrying about index errors:\n```python\n>>> page.css('.product').first # First Selector or None\n\n>>> page.css('.product').last # Last Selector or None\n\n>>> page.css('.nonexistent').first # Returns None instead of raising IndexError\n```\n\nIf you are too lazy like me and want to know the number of [Selector](#selector) instances in a [Selectors](#selectors) instance. You can do this:\n```python\npage.css('.product_pod').length\n```\nwhich is equivalent to\n```python\nlen(page.css('.product_pod'))\n```\nYup, like JavaScript :)\n\n## TextHandler\nThis class is mandatory to understand, as all methods/properties that should return a string for you will return `TextHandler`, and the ones that should return a list of strings will return [TextHandlers](#texthandlers) instead.\n\nTextHandler is a subclass of the standard Python string, so you can do anything with it that you can do with a Python string. So, what is the difference that requires a different naming?\n\nOf course, TextHandler provides extra methods and properties that standard Python strings can't do. We will review them now, but remember that all methods and properties in all classes that return string(s) return TextHandler, which opens the door for creativity and makes the code shorter and cleaner, as you will see. Also, you can import it directly and use it on any string, which we will explain [later](../development/scrapling_custom_types.md).\n### Usage\nFirst, before discussing the added methods, you need to know that all operations on it, like slicing, accessing by index, etc., and methods like `split`, `replace`, `strip`, etc., all return a `TextHandler` again, so you can chain them as you want. If you find a method or property that returns a standard string instead of `TextHandler`, please open an issue, and we will override it as well.\n\nFirst, we start with the `re` and `re_first` methods. These are the same methods that exist in the other classes ([Selector](#selector), [Selectors](#selectors), and [TextHandlers](#texthandlers)), so they accept the same arguments.\n\n- The `re` method takes a string/compiled regex pattern as the first argument. It searches the data for all strings matching the regex and returns them as a [TextHandlers](#texthandlers) instance. The `re_first` method takes the same arguments and behaves similarly, but, as you probably figured out from the name, it returns only the first result as a `TextHandler` instance.\n \n Also, it takes other helpful arguments, which are:\n \n - **replace_entities**: This is enabled by default. It replaces character entity references with their corresponding characters.\n - **clean_match**: It's disabled by default. This causes the method to ignore all whitespace, including consecutive spaces, while matching.\n - **case_sensitive**: It's enabled by default. As the name implies, disabling it causes the regex to ignore letter case during compilation.\n \n You have seen these examples before; the return result is [TextHandlers](#texthandlers) because we used the `re` method.\n ```python\n >>> page.css('.price_color').re(r'[\\d\\.]+')\n ['51.77',\n '53.74',\n '50.10',\n '47.82',\n '54.23',\n ...]\n \n >>> page.css('.product_pod h3 a::attr(href)').re(r'catalogue/(.*)/index.html')\n ['a-light-in-the-attic_1000',\n 'tipping-the-velvet_999',\n 'soumission_998',\n 'sharp-objects_997',\n ...]\n ```\n To explain the other arguments better, we will use a custom string for each example below\n ```python\n >>> from scrapling import TextHandler\n >>> test_string = TextHandler('hi there') # Hence the two spaces\n >>> test_string.re('hi there')\n >>> test_string.re('hi there', clean_match=True) # Using `clean_match` will clean the string before matching the regex\n ['hi there']\n \n >>> test_string2 = TextHandler('Oh, Hi Mark')\n >>> test_string2.re_first('oh, hi Mark')\n >>> test_string2.re_first('oh, hi Mark', case_sensitive=False) # Hence disabling `case_sensitive`\n 'Oh, Hi Mark'\n \n # Mixing arguments\n >>> test_string.re('hi there', clean_match=True, case_sensitive=False)\n ['hi There']\n ```\n Another use of the idea of replacing strings with `TextHandler` everywhere is that a property like `html_content` returns `TextHandler`, so you can do regex on the HTML content if you want:\n ```python\n >>> page.html_content.re('div class=\".*\">(.*)>> page.css('#page-data::text').get()\n '\\n {\\n \"lastUpdated\": \"2024-09-22T10:30:00Z\",\\n \"totalProducts\": 3\\n }\\n '\n >>> page.css('#page-data::text').get().json()\n {'lastUpdated': '2024-09-22T10:30:00Z', 'totalProducts': 3}\n ```\n Hence, if you didn't specify a text node while selecting an element (like the text content or an attribute text content), the text content will be selected automatically, like this\n ```python\n >>> page.css('#page-data')[0].json()\n {'lastUpdated': '2024-09-22T10:30:00Z', 'totalProducts': 3}\n ```\n The [Selector](#selector) class adds one thing here, too; let's say this is the page we are working with:\n ```html\n \n \n
\n \n
\n \n \n ```\n The [Selector](#selector) class has the `get_all_text` method, which you should be aware of by now. This method returns a `TextHandler`, of course.

\n So, as you know here, if you did something like this\n ```python\n >>> page.css('div::text').get().json()\n ```\n You will get an error because the `div` tag doesn't have any direct text content that can be serialized to JSON; it doesn't have any direct text content at all.

\n In this case, the `get_all_text` method comes to the rescue, so you can do something like that\n ```python\n >>> page.css('div')[0].get_all_text(ignore_tags=[]).json()\n {'lastUpdated': '2024-09-22T10:30:00Z', 'totalProducts': 3}\n ```\n I used the `ignore_tags` argument here because the default value of it is `('script', 'style',)`, as you are aware.

\n Another related behavior to be aware of occurs when using any fetcher, which we will explain later. If you have a JSON response like this example:\n ```python\n >>> page = Selector(\"\"\"{\"some_key\": \"some_value\"}\"\"\")\n ```\n Because the [Selector](#selector) class is optimized to deal with HTML pages, it will deal with it as a broken HTML response and fix it, so if you used the `html_content` property, you get this\n ```python\n >>> page.html_content\n '

{\"some_key\": \"some_value\"}

'\n ```\n Here, you can use the `json` method directly, and it will work\n ```python\n >>> page.json()\n {'some_key': 'some_value'}\n ```\n You might wonder how this happened, given that the `html` tag doesn't contain direct text.
\n Well, for cases like JSON responses, I made the [Selector](#selector) class keep a raw copy of the content it receives. This way, when you use the `.json()` method, it checks for that raw copy and then converts it to JSON. If the raw copy is unavailable, as with the elements, it checks the current element's text content; otherwise, it uses the `get_all_text` method directly.
\n\n- Another handy method is `.clean()`, which will remove all white spaces and consecutive spaces for you and return a new `TextHandler` instance\n```python\n>>> TextHandler('\\n wonderful idea, \\reh?').clean()\n'wonderful idea, eh?'\n```\nAlso, you can pass the `remove_entities` argument to make `clean` replace HTML entities with their corresponding characters.\n\n- Another method that might be helpful in some cases is the `.sort()` method to sort the string for you, as you do with lists\n```python\n>>> TextHandler('acb').sort()\n'abc'\n```\nOr do it in reverse:\n```python\n>>> TextHandler('acb').sort(reverse=True)\n'cba'\n```\n\nOther methods and properties will be added over time, but remember that this class is returned in place of strings nearly everywhere in the library.\n\n## TextHandlers\nYou probably guessed it: This class is similar to [Selectors](#selectors) and [Selector](#selector), but here it inherits the same logic and method as standard lists, with only `re` and `re_first` as new methods.\n\nThe only difference is that the `re_first` method logic here runs `re` on each [TextHandler](#texthandler) and returns the first result, or `None`. Nothing new needs to be explained here, but new methods will be added over time.\n\n## AttributesHandler\nThis is a read-only version of Python's standard dictionary, or `dict`, used solely to store the attributes of each element/[Selector](#selector) instance.\n```python\n>>> print(page.find('script').attrib)\n{'id': 'page-data', 'type': 'application/json'}\n>>> type(page.find('script').attrib).__name__\n'AttributesHandler'\n```\nBecause it's read-only, it will use fewer resources than the standard dictionary. Still, it has the same dictionary method and properties, except those that allow you to modify/override the data.\n\nIt currently adds two extra simple methods:\n\n- The `search_values` method\n\n In standard dictionaries, you can do `dict.get(\"key_name\")` to check if a key exists. However, if you want to search by values rather than keys, you will need some additional code lines. This method does that for you. It allows you to search the current attributes by values and returns a dictionary of each matching item.\n \n A simple example would be\n ```python\n >>> for i in page.find('script').attrib.search_values('page-data'):\n print(i)\n {'id': 'page-data'}\n ```\n But this method provides the `partial` argument as well, which allows you to search by part of the value:\n ```python\n >>> for i in page.find('script').attrib.search_values('page', partial=True):\n print(i)\n {'id': 'page-data'}\n ```\n These examples won't happen in the real world; most likely, a more real-world example would be using it with the `find_all` method to find all elements that have a specific value in their arguments:\n ```python\n >>> page.find_all(lambda element: list(element.attrib.search_values('product')))\n [,\n ,\n ]\n ```\n All these elements have 'product' as the value for the `class` attribute.\n \n Hence, I used the `list` function here because `search_values` returns a generator, so it would be `True` for all elements.\n\n- The `json_string` property\n\n This property converts current attributes to a JSON string if the attributes are JSON serializable; otherwise, it throws an error.\n \n ```python\n >>>page.find('script').attrib.json_string\n b'{\"id\":\"page-data\",\"type\":\"application/json\"}'\n ```" }, { "path": "docs/parsing/selection.md", "content": "# Querying elements\nScrapling currently supports parsing HTML pages exclusively, so it doesn't support XML feeds. This decision was made because the adaptive feature won't work with XML, but that might change soon, so stay tuned :)\n\nIn Scrapling, there are five main ways to find elements:\n\n1. CSS3 Selectors\n2. XPath Selectors\n3. Finding elements based on filters/conditions.\n4. Finding elements whose content contains a specific text\n5. Finding elements whose content matches a specific regex\n\nOf course, there are other indirect ways to find elements with Scrapling, but here we will discuss the main ways in detail. We will also bring up one of the most remarkable features of Scrapling: the ability to find elements that are similar to the element you have; you can jump to that section directly from [here](#finding-similar-elements).\n\nIf you are new to Web Scraping, have little to no experience writing selectors, and want to start quickly, I recommend you jump directly to learning the `find`/`find_all` methods from [here](#filters-based-searching).\n\n## CSS/XPath selectors\n\n### What are CSS selectors?\n[CSS](https://en.wikipedia.org/wiki/CSS) is a language for applying styles to HTML documents. It defines selectors to associate those styles with specific HTML elements.\n\nScrapling implements CSS3 selectors as described in the [W3C specification](http://www.w3.org/TR/2011/REC-css3-selectors-20110929/). CSS selectors support comes from `cssselect`, so it's better to read about which [selectors are supported from cssselect](https://cssselect.readthedocs.io/en/latest/#supported-selectors) and pseudo-functions/elements.\n\nAlso, Scrapling implements some non-standard pseudo-elements like:\n\n* To select text nodes, use ``::text``.\n* To select attribute values, use ``::attr(name)`` where name is the name of the attribute that you want the value of\n\nIn short, if you come from Scrapy/Parsel, you will find the same logic for selectors here to make it easier. No need to implement a stranger logic to the one that most of us are used to :)\n\nTo select elements with CSS selectors, use the `css` method, which returns `Selectors`. Use `[0]` to get the first element, or `.get()` / `.getall()` to extract text values from text/attribute pseudo-selectors.\n\n### What are XPath selectors?\n[XPath](https://en.wikipedia.org/wiki/XPath) is a language for selecting nodes in XML documents, which can also be used with HTML. This [cheatsheet](https://devhints.io/xpath) is a good resource for learning about [XPath](https://en.wikipedia.org/wiki/XPath). Scrapling adds XPath selectors directly through [lxml](https://lxml.de/).\n\nIn short, it is the same situation as CSS Selectors; if you come from Scrapy/Parsel, you will find the same logic for selectors here. However, Scrapling doesn't implement the XPath extension function `has-class` as Scrapy/Parsel does. Instead, it provides the `has_class` method, which can be used on elements returned for the same purpose.\n\nTo select elements with XPath selectors, you have the `xpath` method. Again, this method follows the same logic as the CSS selectors method above.\n\n> Note that each method of `css` and `xpath` has additional arguments, but we didn't explain them here, as they are all about the adaptive feature. The adaptive feature will have its own page later to be described in detail.\n\n### Selectors examples\nLet's see some shared examples of using CSS and XPath Selectors.\n\nSelect all elements with the class `product`.\n```python\nproducts = page.css('.product')\nproducts = page.xpath('//*[@class=\"product\"]')\n```\n!!! info \"Note:\"\n\n The XPath one won't be accurate if there's another class; **it's always better to rely on CSS for selecting by class**\n\nSelect the first element with the class `product`.\n```python\nproduct = page.css('.product')[0]\nproduct = page.xpath('//*[@class=\"product\"]')[0]\n```\nGet the text of the first element with the `h1` tag name\n```python\ntitle = page.css('h1::text').get()\ntitle = page.xpath('//h1//text()').get()\n```\nWhich is the same as doing\n```python\ntitle = page.css('h1')[0].text\ntitle = page.xpath('//h1')[0].text\n```\nGet the `href` attribute of the first element with the `a` tag name\n```python\nlink = page.css('a::attr(href)').get()\nlink = page.xpath('//a/@href').get()\n```\nSelect the text of the first element with the `h1` tag name, which contains `Phone`, and under an element with class `product`.\n```python\ntitle = page.css('.product h1:contains(\"Phone\")::text').get()\ntitle = page.xpath('//*[@class=\"product\"]//h1[contains(text(),\"Phone\")]/text()').get()\n```\nYou can nest and chain selectors as you want, given that they return results\n```python\npage.css('.product')[0].css('h1:contains(\"Phone\")::text').get()\npage.xpath('//*[@class=\"product\"]')[0].xpath('//h1[contains(text(),\"Phone\")]/text()').get()\npage.xpath('//*[@class=\"product\"]')[0].css('h1:contains(\"Phone\")::text').get()\n```\nAnother example\n\nAll links that have 'image' in their 'href' attribute\n```python\nlinks = page.css('a[href*=\"image\"]')\nlinks = page.xpath('//a[contains(@href, \"image\")]')\nfor index, link in enumerate(links):\n link_value = link.attrib['href'] # Cleaner than link.css('::attr(href)').get()\n link_text = link.text\n print(f'Link number {index} points to this url {link_value} with text content as \"{link_text}\"')\n```\n\n## Text-content selection\nScrapling provides the ability to select elements based on their direct text content, and you have two ways to do this:\n\n1. Elements whose direct text content contains the given text with many options through the `find_by_text` method.\n2. Elements whose direct text content matches the given regex pattern with many options through the `find_by_regex` method.\n\nWhat you can do with `find_by_text` can be done with `find_by_regex` if you are good enough with regular expressions (regex), but we are providing more options to make them easier for all users to access.\n\nWith `find_by_text`, you pass the text as the first argument; with `find_by_regex`, the regex pattern is the first argument. Both methods share the following arguments:\n\n* **first_match**: If `True` (the default), the method used will return the first result it finds.\n* **case_sensitive**: If `True`, the case of the letters will be considered.\n* **clean_match**: If `True`, all whitespaces and consecutive spaces will be replaced with a single space before matching.\n\nBy default, Scrapling searches for the exact matching of the text/pattern you pass to `find_by_text`, so the text content of the wanted element has to be ONLY the text you input, but that's why it also has one extra argument, which is:\n\n* **partial**: If enabled, `find_by_text` will return elements that contain the input text. So it's not an exact match anymore\n\n!!! abstract \"Note:\"\n\n The method `find_by_regex` can accept both regular strings and a compiled regex pattern as its first argument, as you will see in the upcoming examples.\n\n### Finding Similar Elements\nOne of the most remarkable new features Scrapling puts on the table is the ability to tell Scrapling to find elements similar to the element at hand. This feature's inspiration came from the AutoScraper library, but in Scrapling, it can be used on elements found by any method. Most of its usage would likely occur after finding elements through text content, similar to how AutoScraper works, making it convenient to explain here.\n\nSo, how does it work?\n\nImagine a scenario where you found a product by its title, for example, and you want to extract other products listed in the same table/container. With the element you have, you can call the method `.find_similar()` on it, and Scrapling will:\n\n1. Find all page elements with the same DOM tree depth as this element. \n2. All found elements will be checked, and those without the same tag name, parent tag name, and grandparent tag name will be dropped.\n3. Now we are sure (like 99% sure) that these elements are the ones we want, but as a last check, Scrapling will use fuzzy matching to drop the elements whose attributes don't look like the attributes of our element. There's a percentage to control this step, and I recommend you not play with it unless the default settings don't get the elements you want.\n\nThat's a lot of talking, I know, but I had to go deep. I will give examples of using this method in the next section, but first, these are the arguments that can be passed to this method:\n\n* **similarity_threshold**: This is the percentage we discussed in step 3 for comparing elements' attributes. The default value is 0.2. In Simpler words, the tag attributes of both elements should be at least 20% similar. If you want to turn off this check (basically Step 3), you can set this attribute to 0, but I recommend you read what the other arguments do first.\n* **ignore_attributes**: The attribute names passed will be ignored while matching the attributes in the last step. The default value is `('href', 'src',)` because URLs can change significantly across elements, making them unreliable.\n* **match_text**: If `True`, the element's text content will be considered when matching (Step 3). Using this argument in typical cases is not recommended, but it depends.\n\nNow, let's check out the examples below.\n\n### Examples\nLet's see some shared examples of finding elements with raw text and regex.\n\nI will use the `Fetcher` class with these examples, but it will be explained in detail later.\n```python\nfrom scrapling.fetchers import Fetcher\npage = Fetcher.get('https://books.toscrape.com/index.html')\n```\nFind the first element whose text fully matches this text\n```python\n>>> page.find_by_text('Tipping the Velvet')\n\n```\nCombining it with `page.urljoin` to return the full URL from the relative `href`.\n```python\n>>> page.find_by_text('Tipping the Velvet').attrib['href']\n'catalogue/tipping-the-velvet_999/index.html'\n>>> page.urljoin(page.find_by_text('Tipping the Velvet').attrib['href'])\n'https://books.toscrape.com/catalogue/tipping-the-velvet_999/index.html'\n```\nGet all matches if there are more (notice it returns a list)\n```python\n>>> page.find_by_text('Tipping the Velvet', first_match=False)\n[]\n```\nGet all elements that contain the word `the` (Partial matching)\n```python\n>>> results = page.find_by_text('the', partial=True, first_match=False)\n>>> [i.text for i in results]\n['A Light in the ...',\n 'Tipping the Velvet',\n 'The Requiem Red',\n 'The Dirty Little Secrets ...',\n 'The Coming Woman: A ...',\n 'The Boys in the ...',\n 'The Black Maria',\n 'Mesaerion: The Best Science ...',\n \"It's Only the Himalayas\"]\n```\nThe search is case-insensitive, so those results include `The`, not just the lowercase `the`; let's limit the search to elements with `the` only.\n```python\n>>> results = page.find_by_text('the', partial=True, first_match=False, case_sensitive=True)\n>>> [i.text for i in results]\n['A Light in the ...',\n 'Tipping the Velvet',\n 'The Boys in the ...',\n \"It's Only the Himalayas\"]\n```\nGet the first element whose text content matches my price regex\n```python\n>>> page.find_by_regex(r'ยฃ[\\d\\.]+')\nยฃ51.77

' parent='

\n>>> page.find_by_regex(r'ยฃ[\\d\\.]+').text\n'ยฃ51.77'\n```\nIt's the same if you pass the compiled regex as well; Scrapling will detect the input type and act upon that:\n```python\n>>> import re\n>>> regex = re.compile(r'ยฃ[\\d\\.]+')\n>>> page.find_by_regex(regex)\nยฃ51.77

' parent='

\n>>> page.find_by_regex(regex).text\n'ยฃ51.77'\n```\nGet all elements that match the regex\n```python\n>>> page.find_by_regex(r'ยฃ[\\d\\.]+', first_match=False)\n[ยฃ51.77

' parent='

,\n ยฃ53.74

' parent='

,\n ยฃ50.10

' parent='

,\n ยฃ47.82

' parent='

,\n ...]\n```\nAnd so on...\n\nFind all elements similar to the current element in location and attributes. For our case, ignore the 'title' attribute while matching\n```python\n>>> element = page.find_by_text('Tipping the Velvet')\n>>> element.find_similar(ignore_attributes=['title'])\n[,\n ,\n ,\n...]\n```\nNotice that the number of elements is 19, not 20, because the current element is not included in the results.\n```python\n>>> len(element.find_similar(ignore_attributes=['title']))\n19\n```\nGet the `href` attribute from all similar elements\n```python\n>>> [\n element.attrib['href']\n for element in element.find_similar(ignore_attributes=['title'])\n]\n['catalogue/a-light-in-the-attic_1000/index.html',\n 'catalogue/soumission_998/index.html',\n 'catalogue/sharp-objects_997/index.html',\n ...]\n```\nTo increase the complexity a little bit, let's say we want to get all the books' data using that element as a starting point for some reason\n```python\n>>> for product in element.parent.parent.find_similar():\n print({\n \"name\": product.css('h3 a::text').get(),\n \"price\": product.css('.price_color')[0].re_first(r'[\\d\\.]+'),\n \"stock\": product.css('.availability::text').getall()[-1].clean()\n })\n{'name': 'A Light in the ...', 'price': '51.77', 'stock': 'In stock'}\n{'name': 'Soumission', 'price': '50.10', 'stock': 'In stock'}\n{'name': 'Sharp Objects', 'price': '47.82', 'stock': 'In stock'}\n...\n```\n### Advanced examples \nSee more advanced or real-world examples using the `find_similar` method.\n\nE-commerce Product Extraction\n```python\ndef extract_product_grid(page):\n # Find the first product card\n first_product = page.find_by_text('Add to Cart').find_ancestor(\n lambda e: e.has_class('product-card')\n )\n\n # Find similar product cards\n products = first_product.find_similar()\n\n return [\n {\n 'name': p.css('h3::text').get(),\n 'price': p.css('.price::text').re_first(r'\\d+\\.\\d{2}'),\n 'stock': 'In stock' in p.text,\n 'rating': p.css('.rating')[0].attrib.get('data-rating')\n }\n for p in products\n ]\n```\nTable Row Extraction\n```python\ndef extract_table_data(page):\n # Find the first data row\n first_row = page.css('table tbody tr')[0]\n\n # Find similar rows\n rows = first_row.find_similar()\n\n return [\n {\n 'column1': row.css('td:nth-child(1)::text').get(),\n 'column2': row.css('td:nth-child(2)::text').get(),\n 'column3': row.css('td:nth-child(3)::text').get()\n }\n for row in rows\n ]\n```\nForm Field Extraction\n```python\ndef extract_form_fields(page):\n # Find first form field container\n first_field = page.css('input')[0].find_ancestor(\n lambda e: e.has_class('form-field')\n )\n\n # Find similar field containers\n fields = first_field.find_similar()\n\n return [\n {\n 'label': f.css('label::text').get(),\n 'type': f.css('input')[0].attrib.get('type'),\n 'required': 'required' in f.css('input')[0].attrib\n }\n for f in fields\n ]\n```\nExtracting reviews from a website\n```python\ndef extract_reviews(page):\n # Find first review\n first_review = page.find_by_text('Great product!')\n review_container = first_review.find_ancestor(\n lambda e: e.has_class('review')\n )\n \n # Find similar reviews\n all_reviews = review_container.find_similar()\n \n return [\n {\n 'text': r.css('.review-text::text').get(),\n 'rating': r.attrib.get('data-rating'),\n 'author': r.css('.reviewer::text').get()\n }\n for r in all_reviews\n ]\n```\n## Filters-based searching\nThis search method is arguably the best way to find elements in Scrapling, as it is powerful and easier for newcomers to Web Scraping to learn than writing selectors. \n\nInspired by BeautifulSoup's `find_all` function, you can find elements using the `find_all` and `find` methods. Both methods can accept multiple filters and return all elements on the pages where all these filters apply.\n\nTo be more specific:\n\n* Any string passed is considered a tag name.\n* Any iterable passed, like List/Tuple/Set, will be considered as an iterable of tag names.\n* Any dictionary is considered a mapping of HTML element(s), attribute names, and attribute values.\n* Any regex patterns passed are used to filter elements by content, like the `find_by_regex` method\n* Any functions passed are used to filter elements\n* Any keyword argument passed is considered as an HTML element attribute with its value.\n\nIt collects all passed arguments and keywords, and each filter passes its results to the following filter in a waterfall-like filtering system.\n\nIt filters all elements in the current page/element in the following order:\n\n1. All elements with the passed tag name(s) get collected.\n2. All elements that match all passed attribute(s) are collected; if a previous filter is used, then previously collected elements are filtered.\n3. All elements that match all passed regex patterns are collected, or if previous filter(s) are used, then previously collected elements are filtered.\n4. All elements that fulfill all passed function(s) are collected; if a previous filter(s) is used, then previously collected elements are filtered.\n\n!!! note \"Notes:\"\n\n 1. As you probably understood, the filtering process always starts from the first filter it finds in the filtering order above. So, if no tag name(s) are passed but attributes are passed, the process starts from that step (number 2), and so on.\n 2. The order in which you pass the arguments doesn't matter. The only order considered is the one explained above.\n\nCheck examples to clear any confusion :)\n\n### Examples\n```python\n>>> from scrapling.fetchers import Fetcher\n>>> page = Fetcher.get('https://quotes.toscrape.com/')\n```\nFind all elements with the tag name `div`.\n```python\n>>> page.find_all('div')\n[

,\n
,\n...]\n```\nFind all div elements with a class that equals `quote`.\n```python\n>>> page.find_all('div', class_='quote')\n[,\n ,\n...]\n```\nSame as above.\n```python\n>>> page.find_all('div', {'class': 'quote'})\n[,\n ,\n...]\n```\nFind all elements with a class that equals `quote`.\n```python\n>>> page.find_all({'class': 'quote'})\n[,\n ,\n...]\n```\nFind all div elements with a class that equals `quote` and contains the element `.text`, which contains the word 'world' in its content.\n```python\n>>> page.find_all('div', {'class': 'quote'}, lambda e: \"world\" in e.css('.text::text').get())\n[]\n```\nFind all elements that have children.\n```python\n>>> page.find_all(lambda element: len(element.children) > 0)\n[,\n Quote...' parent='<html lang=\"en\"><head><meta charset=\"UTF...'>,\n <data='<body> <div class=\"container\"> <div clas...' parent='<html lang=\"en\"><head><meta charset=\"UTF...'>,\n...]\n```\nFind all elements that contain the word 'world' in their content.\n```python\n>>> page.find_all(lambda element: \"world\" in element.text)\n[<data='<span class=\"text\" itemprop=\"text\">โ€œThe...' parent='<div class=\"quote\" itemscope itemtype=\"h...'>,\n <data='<a class=\"tag\" href=\"/tag/world/page/1/\"...' parent='<div class=\"tags\"> Tags: <meta class=\"ke...'>]\n```\nFind all span elements that match the given regex\n```python\n>>> page.find_all('span', re.compile(r'world'))\n[<data='<span class=\"text\" itemprop=\"text\">โ€œThe...' parent='<div class=\"quote\" itemscope itemtype=\"h...'>]\n```\nFind all div and span elements with class 'quote' (No span elements like that, so only div returned)\n```python\n>>> page.find_all(['div', 'span'], {'class': 'quote'})\n[<data='<div class=\"quote\" itemscope itemtype=\"h...' parent='<div class=\"col-md-8\"> <div class=\"quote...'>,\n <data='<div class=\"quote\" itemscope itemtype=\"h...' parent='<div class=\"col-md-8\"> <div class=\"quote...'>,\n...]\n```\nMix things up\n```python\n>>> page.find_all({'itemtype':\"http://schema.org/CreativeWork\"}, 'div').css('.author::text').getall()\n['Albert Einstein',\n 'J.K. Rowling',\n...]\n```\nA bonus pro tip: Find all elements whose `href` attribute's value ends with the word 'Einstein'.\n```python\n>>> page.find_all({'href$': 'Einstein'})\n[<data='<a href=\"/author/Albert-Einstein\">(about...' parent='<span>by <small class=\"author\" itemprop=...'>,\n <data='<a href=\"/author/Albert-Einstein\">(about...' parent='<span>by <small class=\"author\" itemprop=...'>,\n <data='<a href=\"/author/Albert-Einstein\">(about...' parent='<span>by <small class=\"author\" itemprop=...'>]\n```\nAnother pro tip: Find all elements whose `href` attribute's value has '/author/' in it\n```python\n>>> page.find_all({'href*': '/author/'})\n[<data='<a href=\"/author/Albert-Einstein\">(about...' parent='<span>by <small class=\"author\" itemprop=...'>,\n <data='<a href=\"/author/J-K-Rowling\">(about)</a...' parent='<span>by <small class=\"author\" itemprop=...'>,\n <data='<a href=\"/author/Albert-Einstein\">(about...' parent='<span>by <small class=\"author\" itemprop=...'>,\n...]\n```\nAnd so on...\n\n## Generating selectors\nYou can always generate CSS/XPath selectors for any element that can be reused here or anywhere else, and the most remarkable thing is that it doesn't matter what method you used to find that element!\n\nGenerate a short CSS selector for the `url_element` element (if possible, create a short one; otherwise, it's a full selector)\n```python\n>>> url_element = page.find({'href*': '/author/'})\n>>> url_element.generate_css_selector\n'body > div > div:nth-of-type(2) > div > div > span:nth-of-type(2) > a'\n```\nGenerate a full CSS selector for the `url_element` element from the start of the page\n```python\n>>> url_element.generate_full_css_selector\n'body > div > div:nth-of-type(2) > div > div > span:nth-of-type(2) > a'\n```\nGenerate a short XPath selector for the `url_element` element (if possible, create a short one; otherwise, it's a full selector)\n```python\n>>> url_element.generate_xpath_selector\n'//body/div/div[2]/div/div/span[2]/a'\n```\nGenerate a full XPath selector for the `url_element` element from the start of the page\n```python\n>>> url_element.generate_full_xpath_selector\n'//body/div/div[2]/div/div/span[2]/a'\n```\n!!! abstract \"Note:\"\n\n When you tell Scrapling to create a short selector, it tries to find a unique element to use in generation as a stop point, like an element with an `id` attribute, but in our case, there wasn't any, so that's why the short and the full selector will be the same.\n\n## Using selectors with regular expressions\nSimilar to `parsel`/`scrapy`, `re` and `re_first` methods are available for extracting data using regular expressions. However, unlike the former libraries, these methods are in nearly all classes like `Selector`/`Selectors`/`TextHandler` and `TextHandlers`, which means you can use them directly on the element even if you didn't select a text node. \n\nWe will have a deep look at it while explaining the [TextHandler](main_classes.md#texthandler) class, but in general, it works like the examples below:\n```python\n>>> page.css('.price_color')[0].re_first(r'[\\d\\.]+')\n'51.77'\n\n>>> page.css('.price_color').re_first(r'[\\d\\.]+')\n'51.77'\n\n>>> page.css('.price_color').re(r'[\\d\\.]+')\n['51.77',\n '53.74',\n '50.10',\n '47.82',\n '54.23',\n...]\n\n>>> page.css('.product_pod h3 a::attr(href)').re(r'catalogue/(.*)/index.html')\n['a-light-in-the-attic_1000',\n 'tipping-the-velvet_999',\n 'soumission_998',\n 'sharp-objects_997',\n...]\n\n>>> filtering_function = lambda e: e.parent.tag == 'h3' and e.parent.parent.has_class('product_pod') # As above selector\n>>> page.find('a', filtering_function).attrib['href'].re(r'catalogue/(.*)/index.html')\n['a-light-in-the-attic_1000']\n\n>>> page.find_by_text('Tipping the Velvet').attrib['href'].re(r'catalogue/(.*)/index.html')\n['tipping-the-velvet_999']\n```\nAnd so on. You get the idea. We will explain this in more detail on the next page, along with the [TextHandler](main_classes.md#texthandler) class." }, { "path": "docs/requirements.txt", "content": "zensical>=0.0.27\nmkdocstrings>=1.0.3\nmkdocstrings-python>=2.0.3\ngriffe-inherited-docstrings>=1.1.3\ngriffe-runtime-objects>=0.3.1\ngriffe-sphinx>=0.2.1\nblack>=26.1.0\npngquant" }, { "path": "docs/spiders/advanced.md", "content": "# Advanced usages\n\n## Introduction\n\n!!! success \"Prerequisites\"\n\n 1. You've read the [Getting started](getting-started.md) page and know how to create and run a basic spider.\n\nThis page covers the spider system's advanced features: concurrency control, pause/resume, streaming, lifecycle hooks, statistics, and logging.\n\n## Concurrency Control\n\nThe spider system uses three class attributes to control how aggressively it crawls:\n\n| Attribute | Default | Description |\n|----------------------------------|---------|------------------------------------------------------------------|\n| `concurrent_requests` | `4` | Maximum number of requests being processed at the same time |\n| `concurrent_requests_per_domain` | `0` | Maximum concurrent requests per domain (0 = no per-domain limit) |\n| `download_delay` | `0.0` | Seconds to wait before each request |\n\n```python\nclass PoliteSpider(Spider):\n name = \"polite\"\n start_urls = [\"https://example.com\"]\n\n # Be gentle with the server\n concurrent_requests = 4\n concurrent_requests_per_domain = 2\n download_delay = 1.0 # Wait 1 second between requests\n\n async def parse(self, response: Response):\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\nWhen `concurrent_requests_per_domain` is set, each domain gets its own concurrency limiter in addition to the global limit. This is useful when crawling multiple domains simultaneously โ€” you can allow high global concurrency while being polite to each individual domain.\n\n!!! tip\n\n The `download_delay` parameter adds a fixed wait before every request, regardless of the domain. Use it for simple rate limiting.\n\n### Using uvloop\n\nThe `start()` method accepts a `use_uvloop` parameter to use the faster [uvloop](https://github.com/MagicStack/uvloop)/[winloop](https://github.com/nicktimko/winloop) event loop implementation, if available:\n\n```python\nresult = MySpider().start(use_uvloop=True)\n```\n\nThis can improve throughput for I/O-heavy crawls. You'll need to install `uvloop` (Linux/macOS) or `winloop` (Windows) separately.\n\n## Pause & Resume\n\nThe spider supports graceful pause-and-resume via checkpointing. To enable it, pass a `crawldir` directory to the spider constructor:\n\n```python\nspider = MySpider(crawldir=\"crawl_data/my_spider\")\nresult = spider.start()\n\nif result.paused:\n print(\"Crawl was paused. Run again to resume.\")\nelse:\n print(\"Crawl completed!\")\n```\n\n### How It Works\n\n1. **Pausing**: Press `Ctrl+C` during a crawl. The spider waits for all in-flight requests to finish, saves a checkpoint (pending requests + a set of seen request fingerprints), and then exits.\n2. **Force stopping**: Press `Ctrl+C` a second time to stop immediately without waiting for active tasks.\n3. **Resuming**: Run the spider again with the same `crawldir`. It detects the checkpoint, restores the queue and seen set, and continues from where it left off โ€” skipping `start_requests()`.\n4. **Cleanup**: When a crawl completes normally (not paused), the checkpoint files are deleted automatically.\n\n**Checkpoints are also saved periodically during the crawl (every 5 minutes by default).** \n\nYou can change the interval as follows:\n\n```python\n# Save checkpoint every 2 minutes\nspider = MySpider(crawldir=\"crawl_data/my_spider\", interval=120.0)\n```\n\nThe writing to the disk is atomic, so it's totally safe.\n\n!!! tip\n\n Pressing `Ctrl+C` during a crawl always causes the spider to close gracefully, even if the checkpoint system is not enabled. Doing it again without waiting forces the spider to close immediately.\n\n### Knowing If You're Resuming\n\nThe `on_start()` hook receives a `resuming` flag:\n\n```python\nasync def on_start(self, resuming: bool = False):\n if resuming:\n self.logger.info(\"Resuming from checkpoint!\")\n else:\n self.logger.info(\"Starting fresh crawl\")\n```\n\n## Streaming\n\nFor long-running spiders or applications that need real-time access to scraped items, use the `stream()` method instead of `start()`:\n\n```python\nimport anyio\n\nasync def main():\n spider = MySpider()\n async for item in spider.stream():\n print(f\"Got item: {item}\")\n # Access real-time stats\n print(f\"Items so far: {spider.stats.items_scraped}\")\n print(f\"Requests made: {spider.stats.requests_count}\")\n\nanyio.run(main)\n```\n\nKey differences from `start()`:\n\n- `stream()` must be called from an async context\n- Items are yielded one by one as they're scraped, not collected into a list\n- You can access `spider.stats` during iteration for real-time statistics\n\n!!! abstract \n\n The full list of all stats that can be accessed by `spider.stats` is explained below [here](#results--statistics)\n\nYou can use it with the checkpoint system too, so it's easy to build UI on top of spiders. UIs that have real-time data and can be paused/resumed.\n\n```python\nimport anyio\n\nasync def main():\n spider = MySpider(crawldir=\"crawl_data/my_spider\")\n async for item in spider.stream():\n print(f\"Got item: {item}\")\n # Access real-time stats\n print(f\"Items so far: {spider.stats.items_scraped}\")\n print(f\"Requests made: {spider.stats.requests_count}\")\n\nanyio.run(main)\n```\nYou can also use `spider.pause()` to shut down the spider in the code above. If you used it without enabling the checkpoint system, it will just close the crawl.\n\n## Lifecycle Hooks\n\nThe spider provides several hooks you can override to add custom behavior at different stages of the crawl:\n\n### on_start\n\nCalled before crawling begins. Use it for setup tasks like loading data or initializing resources:\n\n```python\nasync def on_start(self, resuming: bool = False):\n self.logger.info(\"Spider starting up\")\n # Load seed URLs from a database, initialize counters, etc.\n```\n\n### on_close\n\nCalled after crawling finishes (whether completed or paused). Use it for cleanup:\n\n```python\nasync def on_close(self):\n self.logger.info(\"Spider shutting down\")\n # Close database connections, flush buffers, etc.\n```\n\n### on_error\n\nCalled when a request fails with an exception. Use it for error tracking or custom recovery logic:\n\n```python\nasync def on_error(self, request: Request, error: Exception):\n self.logger.error(f\"Failed: {request.url} - {error}\")\n # Log to error tracker, save failed URL for later, etc.\n```\n\n### on_scraped_item\n\nCalled for every scraped item before it's added to the results. Return the item (modified or not) to keep it, or return `None` to drop it:\n\n```python\nasync def on_scraped_item(self, item: dict) -> dict | None:\n # Drop items without a title\n if not item.get(\"title\"):\n return None\n\n # Modify items (e.g., add timestamps)\n item[\"scraped_at\"] = \"2026-01-01\"\n return item\n```\n\n!!! tip\n\n This hook can also be used to direct items through your own pipelines and drop them from the spider.\n\n### start_requests\n\nOverride `start_requests()` for custom initial request generation instead of using `start_urls`:\n\n```python\nasync def start_requests(self):\n # POST request to log in first\n yield Request(\n \"https://example.com/login\",\n method=\"POST\",\n data={\"user\": \"admin\", \"pass\": \"secret\"},\n callback=self.after_login,\n )\n\nasync def after_login(self, response: Response):\n # Now crawl the authenticated pages\n yield response.follow(\"/dashboard\", callback=self.parse)\n```\n\n## Results & Statistics\n\nThe `CrawlResult` returned by `start()` contains both the scraped items and detailed statistics:\n\n```python\nresult = MySpider().start()\n\n# Items\nprint(f\"Total items: {len(result.items)}\")\nresult.items.to_json(\"output.json\", indent=True)\n\n# Did the crawl complete?\nprint(f\"Completed: {result.completed}\")\nprint(f\"Paused: {result.paused}\")\n\n# Statistics\nstats = result.stats\nprint(f\"Requests: {stats.requests_count}\")\nprint(f\"Failed: {stats.failed_requests_count}\")\nprint(f\"Blocked: {stats.blocked_requests_count}\")\nprint(f\"Offsite filtered: {stats.offsite_requests_count}\")\nprint(f\"Items scraped: {stats.items_scraped}\")\nprint(f\"Items dropped: {stats.items_dropped}\")\nprint(f\"Response bytes: {stats.response_bytes}\")\nprint(f\"Duration: {stats.elapsed_seconds:.1f}s\")\nprint(f\"Speed: {stats.requests_per_second:.1f} req/s\")\n```\n\n### Detailed Stats\n\nThe `CrawlStats` object tracks granular information:\n\n```python\nstats = result.stats\n\n# Status code distribution\nprint(stats.response_status_count)\n# {'status_200': 150, 'status_404': 3, 'status_403': 1}\n\n# Bytes downloaded per domain\nprint(stats.domains_response_bytes)\n# {'example.com': 1234567, 'api.example.com': 45678}\n\n# Requests per session\nprint(stats.sessions_requests_count)\n# {'http': 120, 'stealth': 34}\n\n# Proxies used during the crawl\nprint(stats.proxies)\n# ['http://proxy1:8080', 'http://proxy2:8080']\n\n# Log level counts\nprint(stats.log_levels_counter)\n# {'debug': 200, 'info': 50, 'warning': 3, 'error': 1, 'critical': 0}\n\n# Timing information\nprint(stats.start_time) # Unix timestamp when crawl started\nprint(stats.end_time) # Unix timestamp when crawl finished\nprint(stats.download_delay) # The download delay used (seconds)\n\n# Concurrency settings used\nprint(stats.concurrent_requests) # Global concurrency limit\nprint(stats.concurrent_requests_per_domain) # Per-domain concurrency limit\n\n# Custom stats (set by your spider code)\nprint(stats.custom_stats)\n# {'login_attempts': 3, 'pages_with_errors': 5}\n\n# Export everything as a dict\nprint(stats.to_dict())\n```\n\n## Logging\n\nThe spider has a built-in logger accessible via `self.logger`. It's pre-configured with the spider's name and supports several customization options:\n\n| Attribute | Default | Description |\n|-----------------------|--------------------------------------------------------------|----------------------------------------------------|\n| `logging_level` | `logging.DEBUG` | Minimum log level |\n| `logging_format` | `\"[%(asctime)s]:({spider_name}) %(levelname)s: %(message)s\"` | Log message format |\n| `logging_date_format` | `\"%Y-%m-%d %H:%M:%S\"` | Date format in log messages |\n| `log_file` | `None` | Path to a log file (in addition to console output) |\n\n```python\nimport logging\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n logging_level = logging.INFO\n log_file = \"logs/my_spider.log\"\n\n async def parse(self, response: Response):\n self.logger.info(f\"Processing {response.url}\")\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\nThe log file directory is created automatically if it doesn't exist. Both console and file output use the same format." }, { "path": "docs/spiders/architecture.md", "content": "# Spiders architecture\n\n!!! success \"Prerequisites\"\n\n 1.

You've completed or read the [Main classes](../parsing/main_classes.md) page to understand the [Selector](../parsing/main_classes.md#selector) and [Response](../fetching/choosing.md#response-object) classes.\n\nScrapling's spider system is a Scrapy-inspired async crawling framework designed for concurrent, multi-session crawls with built-in pause/resume support. It brings together Scrapling's parsing engine and fetchers into a unified crawling API while adding scheduling, concurrency control, and checkpointing.\n\nIf you're familiar with Scrapy, you'll feel right at home. If not, don't worry โ€” the system is designed to be straightforward.\n\n## Data Flow\n\nThe diagram below shows how data flows through the spider system when a crawl is running:\n\n<img src=\"../assets/spider_architecture.png\" title=\"Spider architecture diagram by @TrueSkills\" alt=\"Spider architecture diagram by @TrueSkills\" style=\"width: 70%;\"/>\n\nHere's what happens step by step when you run a spider without many details:\n\n1. The **Spider** produces the first batch of `Request` objects. By default, it creates one request for each URL in `start_urls`, but you can override `start_requests()` for custom logic.\n2. The **Scheduler** receives requests and places them in a priority queue, and creates fingerprints for them. Higher-priority requests are dequeued first.\n3. The **Crawler Engine** asks the **Scheduler** to dequeue the next request, respecting concurrency limits (global and per-domain) and download delays. Once the **Crawler Engine** receives the request, it passes it to the **Session Manager**, which routes it to the correct session based on the request's `sid` (session ID).\n4. The **session** fetches the page and returns a [Response](../fetching/choosing.md#response-object) object to the **Crawler Engine**. The engine records statistics and checks for blocked responses. If the response is blocked, the engine retries the request up to `max_blocked_retries` times. Of course, the blocking detection and the retry logic for blocked requests can be customized.\n5. The **Crawler Engine** passes the [Response](../fetching/choosing.md#response-object) to the request's callback. The callback either yields a dictionary, which gets treated as a scraped item, or a follow-up request, which gets sent to the scheduler for queuing.\n6. The cycle repeats from step 2 until the scheduler is empty and no tasks are active, or the spider is paused.\n7. If `crawldir` is set while starting the spider, the **Crawler Engine** periodically saves a checkpoint (pending requests + seen URLs set) to disk. On graceful shutdown (Ctrl+C), a final checkpoint is saved. The next time the spider runs with the same `crawldir`, it resumes from where it left off โ€” skipping `start_requests()` and restoring the scheduler state.\n\n\n## Components\n\n### Spider\n\nThe central class you interact with. You subclass `Spider`, define your `start_urls` and `parse()` method, and optionally configure sessions and override lifecycle hooks.\n\n```python\nfrom scrapling.spiders import Spider, Response, Request\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n\n async def parse(self, response: Response):\n for link in response.css(\"a::attr(href)\").getall():\n yield response.follow(link, callback=self.parse_page)\n\n async def parse_page(self, response: Response):\n yield {\"title\": response.css(\"h1::text\").get(\"\")}\n```\n\n### Crawler Engine\n\nThe engine orchestrates the entire crawl. It manages the main loop, enforces concurrency limits, dispatches requests through the Session Manager, and processes results from callbacks. You don't interact with it directly โ€” the `Spider.start()` and `Spider.stream()` methods handle it for you.\n\n### Scheduler\n\nA priority queue with built-in URL deduplication. Requests are fingerprinted based on their URL, HTTP method, body, and session ID. The scheduler supports `snapshot()` and `restore()` for the checkpoint system, allowing the crawl state to be saved and resumed.\n\n### Session Manager\n\nManages one or more named session instances. Each session is one of:\n\n- [FetcherSession](../fetching/static.md)\n- [AsyncDynamicSession](../fetching/dynamic.md)\n- [AsyncStealthySession](../fetching/stealthy.md)\n\nWhen a request comes in, the Session Manager routes it to the correct session based on the request's `sid` field. Sessions can be started with the spider start (default) or lazily (started on the first use).\n\n### Checkpoint System\n\nAn optional system that, if enabled, saves the crawler's state (pending requests + seen URL fingerprints) to a pickle file on disk. Writes are atomic (temp file + rename) to prevent corruption. Checkpoints are saved periodically at a configurable interval and on graceful shutdown. Upon successful completion (not paused), checkpoint files are automatically cleaned up.\n\n### Output\n\nScraped items are collected in an `ItemList` (a list subclass with `to_json()` and `to_jsonl()` export methods). Crawl statistics are tracked in a `CrawlStats` dataclass which contains a lot of useful info.\n\n\n## Comparison with Scrapy\n\nIf you're coming from Scrapy, here's how Scrapling's spider system maps:\n\n| Concept | Scrapy | Scrapling |\n|--------------------|-------------------------------|-----------------------------------------------------------------|\n| Spider definition | `scrapy.Spider` subclass | `scrapling.spiders.Spider` subclass |\n| Initial requests | `start_requests()` | `async start_requests()` |\n| Callbacks | `def parse(self, response)` | `async def parse(self, response)` |\n| Following links | `response.follow(url)` | `response.follow(url)` |\n| Item output | `yield dict` or `yield Item` | `yield dict` |\n| Request scheduling | Scheduler + Dupefilter | Scheduler with built-in deduplication |\n| Downloading | Downloader + Middlewares | Session Manager with multi-session support |\n| Item processing | Item Pipelines | `on_scraped_item()` hook |\n| Blocked detection | Through custom middlewares | Built-in `is_blocked()` + `retry_blocked_request()` hooks |\n| Concurrency | `CONCURRENT_REQUESTS` setting | `concurrent_requests` class attribute |\n| Domain filtering | `allowed_domains` | `allowed_domains` |\n| Pause/Resume | `JOBDIR` setting | `crawldir` constructor argument |\n| Export | Feed exports | `result.items.to_json()` / `to_jsonl()` or custom through hooks |\n| Running | `scrapy crawl spider_name` | `MySpider().start()` |\n| Streaming | N/A | `async for item in spider.stream()` |\n| Multi-session | N/A | Multiple sessions with different types per spider |" }, { "path": "docs/spiders/getting-started.md", "content": "# Getting started\n\n## Introduction\n\n!!! success \"Prerequisites\"\n\n 1. You've completed or read the [Fetchers basics](../fetching/choosing.md) page to understand the different fetcher types and when to use each one.\n 2. You've completed or read the [Main classes](../parsing/main_classes.md) page to understand the [Selector](../parsing/main_classes.md#selector) and [Response](../fetching/choosing.md#response-object) classes.\n 3. You've read the [Architecture](architecture.md) page for a high-level overview of how the spider system works.\n\nThe spider system lets you build concurrent, multi-page crawlers in just a few lines of code. If you've used Scrapy before, the patterns will feel familiar. If not, this guide will walk you through everything you need to get started.\n\n## Your First Spider\n\nA spider is a class that defines how to crawl and extract data from websites. Here's the simplest possible spider:\n\n```python\nfrom scrapling.spiders import Spider, Response\n\nclass QuotesSpider(Spider):\n name = \"quotes\"\n start_urls = [\"https://quotes.toscrape.com\"]\n\n async def parse(self, response: Response):\n for quote in response.css(\"div.quote\"):\n yield {\n \"text\": quote.css(\"span.text::text\").get(\"\"),\n \"author\": quote.css(\"small.author::text\").get(\"\"),\n }\n```\n\nEvery spider needs three things:\n\n1. **`name`** โ€” A unique identifier for the spider.\n2. **`start_urls`** โ€” A list of URLs to start crawling from.\n3. **`parse()`** โ€” An async generator method that processes each response and yields results.\n\nThe `parse()` method is where the magic happens. You use the same selection methods you'd use with Scrapling's [Selector](../parsing/main_classes.md#selector)/[Response](../fetching/choosing.md#response-object), and `yield` dictionaries to output scraped items.\n\n## Running the Spider\n\nTo run your spider, create an instance and call `start()`:\n\n```python\nresult = QuotesSpider().start()\n```\n\nThe `start()` method handles all the async machinery internally โ€” no need to worry about event loops. While the spider is running, everything that happens is logged to the terminal, and at the end of the crawl, you get very detailed stats.\n\nThose stats are in the returned `CrawlResult` object, which gives you everything you need:\n\n```python\nresult = QuotesSpider().start()\n\n# Access scraped items\nfor item in result.items:\n print(item[\"text\"], \"-\", item[\"author\"])\n\n# Check statistics\nprint(f\"Scraped {result.stats.items_scraped} items\")\nprint(f\"Made {result.stats.requests_count} requests\")\nprint(f\"Took {result.stats.elapsed_seconds:.1f} seconds\")\n\n# Did the crawl finish or was it paused?\nprint(f\"Completed: {result.completed}\")\n```\n\n## Following Links\n\nMost crawls need to follow links across multiple pages. Use `response.follow()` to create follow-up requests:\n\n```python\nfrom scrapling.spiders import Spider, Response\n\nclass QuotesSpider(Spider):\n name = \"quotes\"\n start_urls = [\"https://quotes.toscrape.com\"]\n\n async def parse(self, response: Response):\n # Extract items from the current page\n for quote in response.css(\"div.quote\"):\n yield {\n \"text\": quote.css(\"span.text::text\").get(\"\"),\n \"author\": quote.css(\"small.author::text\").get(\"\"),\n }\n\n # Follow the \"next page\" link\n next_page = response.css(\"li.next a::attr(href)\").get()\n if next_page:\n yield response.follow(next_page, callback=self.parse)\n```\n\n`response.follow()` handles relative URLs automatically โ€” it joins them with the current page's URL. It also sets the current page as the `Referer` header by default.\n\nYou can point follow-up requests at different callback methods for different page types:\n\n```python\nasync def parse(self, response: Response):\n for link in response.css(\"a.product-link::attr(href)\").getall():\n yield response.follow(link, callback=self.parse_product)\n\nasync def parse_product(self, response: Response):\n yield {\n \"name\": response.css(\"h1::text\").get(\"\"),\n \"price\": response.css(\".price::text\").get(\"\"),\n }\n```\n\n!!! note\n\n All callback methods must be async generators (using `async def` and `yield`).\n\n## Exporting Data\n\nThe `ItemList` returned in `result.items` has built-in export methods:\n\n```python\nresult = QuotesSpider().start()\n\n# Export as JSON\nresult.items.to_json(\"quotes.json\")\n\n# Export as JSON with pretty-printing\nresult.items.to_json(\"quotes.json\", indent=True)\n\n# Export as JSON Lines (one JSON object per line)\nresult.items.to_jsonl(\"quotes.jsonl\")\n```\n\nBoth methods create parent directories automatically if they don't exist.\n\n## Filtering Domains\n\nUse `allowed_domains` to restrict the spider to specific domains. This prevents it from accidentally following links to external websites:\n\n```python\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n allowed_domains = {\"example.com\"}\n\n async def parse(self, response: Response):\n for link in response.css(\"a::attr(href)\").getall():\n # Links to other domains are silently dropped\n yield response.follow(link, callback=self.parse)\n```\n\nSubdomains are matched automatically โ€” setting `allowed_domains = {\"example.com\"}` also allows `sub.example.com`, `blog.example.com`, etc.\n\nWhen a request is filtered out, it's counted in `stats.offsite_requests_count` so you can see how many were dropped.\n\n## What's Next\n\nNow that you have the basics, you can explore:\n\n- [Requests & Responses](requests-responses.md) โ€” learn about request priority, deduplication, metadata, and more.\n- [Sessions](sessions.md) โ€” use multiple fetcher types (HTTP, browser, stealth) in a single spider.\n- [Proxy management & blocking](proxy-blocking.md) โ€” rotate proxies across requests and how to handle blocking in the spider.\n- [Advanced features](advanced.md) โ€” concurrency control, pause/resume, streaming, lifecycle hooks, and logging." }, { "path": "docs/spiders/proxy-blocking.md", "content": "# Proxy management and handling Blocks\n\n## Introduction\n\n!!! success \"Prerequisites\"\n\n 1. You've read the [Getting started](getting-started.md) page and know how to create and run a basic spider.\n 2. You've read the [Sessions](sessions.md) page and understand how to configure sessions.\n\nWhen scraping at scale, you'll often need to rotate through multiple proxies to avoid rate limits and blocks. Scrapling's `ProxyRotator` makes this straightforward โ€” it works with all session types and integrates with the spider's blocked request retry system.\n\nIf you don't know what a proxy is or how to choose a good one, [this guide can help](https://substack.thewebscraping.club/p/everything-about-proxies).\n\n## ProxyRotator\n\nThe `ProxyRotator` class manages a list of proxies and rotates through them automatically. Pass it to any session type via the `proxy_rotator` parameter:\n\n```python\nfrom scrapling.spiders import Spider, Response\nfrom scrapling.fetchers import FetcherSession, ProxyRotator\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n\n def configure_sessions(self, manager):\n rotator = ProxyRotator([\n \"http://proxy1:8080\",\n \"http://proxy2:8080\",\n \"http://user:pass@proxy3:8080\",\n ])\n manager.add(\"default\", FetcherSession(proxy_rotator=rotator))\n\n async def parse(self, response: Response):\n # Check which proxy was used\n print(f\"Proxy used: {response.meta.get('proxy')}\")\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\nEach request automatically gets the next proxy in the rotation. The proxy used is stored in `response.meta[\"proxy\"]` so you can track which proxy fetched which page.\n\n\nWhen you use it with browser sessions, you will need some adjustments, like below:\n\n```python\nfrom scrapling.fetchers import AsyncDynamicSession, AsyncStealthySession, ProxyRotator\n\n# String proxies work for all session types\nrotator = ProxyRotator([\n \"http://proxy1:8080\",\n \"http://proxy2:8080\",\n])\n\n# Dict proxies (Playwright format) work for browser sessions\nrotator = ProxyRotator([\n {\"server\": \"http://proxy1:8080\", \"username\": \"user\", \"password\": \"pass\"},\n {\"server\": \"http://proxy2:8080\"},\n])\n\n# Then inside the spider\ndef configure_sessions(self, manager):\n rotator = ProxyRotator([\"http://proxy1:8080\", \"http://proxy2:8080\"])\n manager.add(\"browser\", AsyncStealthySession(proxy_rotator=rotator))\n```\n\n!!! info\n\n 1. You cannot use the `proxy_rotator` argument together with the static `proxy` or `proxies` parameters on the same session. Pick one approach when configuring the session, and override it per request later if you want, as we will show later.\n 2. Remember that by default, all browser-based sessions use a persistent browser context with a pool of tabs. However, since browsers can't set a proxy per tab, when you use a `ProxyRotator`, the fetcher will automatically open a separate context for each proxy, with one tab per context. Once the tab's job is done, both the tab and its context are closed.\n\n## Custom Rotation Strategies\n\nBy default, `ProxyRotator` uses cyclic rotation โ€” it iterates through proxies sequentially, wrapping around at the end.\n\nYou can provide a custom strategy function to change this behavior, but it has to match the below signature:\n\n```python\nfrom scrapling.core._types import ProxyType\n\ndef my_strategy(proxies: list, current_index: int) -> tuple[ProxyType, int]:\n ...\n```\n\nIt receives the list of proxies and the current index, and must return the chosen proxy and the next index.\n\nBelow are some examples of custom rotation strategies you can use.\n\n### Random Rotation\n\n```python\nimport random\nfrom scrapling.fetchers import ProxyRotator\n\ndef random_strategy(proxies, current_index):\n idx = random.randint(0, len(proxies) - 1)\n return proxies[idx], idx\n\nrotator = ProxyRotator(\n [\"http://proxy1:8080\", \"http://proxy2:8080\", \"http://proxy3:8080\"],\n strategy=random_strategy,\n)\n```\n\n### Weighted Rotation\n\n```python\nimport random\n\ndef weighted_strategy(proxies, current_index):\n # First proxy gets 60% of traffic, others split the rest\n weights = [60] + [40 // (len(proxies) - 1)] * (len(proxies) - 1)\n proxy = random.choices(proxies, weights=weights, k=1)[0]\n return proxy, current_index # Index doesn't matter for weighted\n\nrotator = ProxyRotator(proxies, strategy=weighted_strategy)\n```\n\n\n## Per-Request Proxy Override\n\nYou can override the rotator for individual requests by passing `proxy=` as a keyword argument:\n\n```python\nasync def parse(self, response: Response):\n # This request uses the rotator's next proxy\n yield response.follow(\"/page1\", callback=self.parse_page)\n\n # This request uses a specific proxy, bypassing the rotator\n yield response.follow(\n \"/special-page\",\n callback=self.parse_page,\n proxy=\"http://special-proxy:8080\",\n )\n```\n\nThis is useful when certain pages require a specific proxy (e.g., a geo-located proxy for region-specific content).\n\n## Blocked Request Handling\n\nThe spider has built-in blocked request detection and retry. By default, it considers the following HTTP status codes blocked: `401`, `403`, `407`, `429`, `444`, `500`, `502`, `503`, `504`.\n\nThe retry system works like this:\n\n1. After a response comes back, the spider calls the `is_blocked(response)` method.\n2. If blocked, it copies the request and calls the `retry_blocked_request()` method so you can modify it before retrying.\n3. The retried request is re-queued with `dont_filter=True` (bypassing deduplication) and lower priority, so it's not retried right away.\n4. This repeats up to `max_blocked_retries` times (default: 3).\n\n!!! tip\n\n 1. On retry, the previous `proxy`/`proxies` kwargs are cleared from the request automatically, so the rotator assigns a fresh proxy.\n 2. The `max_blocked_retries` attribute is different than the session retries and doesn't share the counter.\n\n### Custom Block Detection\n\nOverride `is_blocked()` to add your own detection logic:\n\n```python\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n\n async def is_blocked(self, response: Response) -> bool:\n # Check status codes (default behavior)\n if response.status in {403, 429, 503}:\n return True\n\n # Check response content\n body = response.body.decode(\"utf-8\", errors=\"ignore\")\n if \"access denied\" in body.lower() or \"rate limit\" in body.lower():\n return True\n\n return False\n\n async def parse(self, response: Response):\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\n### Customizing Retries\n\nOverride `retry_blocked_request()` to modify the request before retrying. The `max_blocked_retries` attribute controls how many times a blocked request is retried (default: 3):\n\n```python\nfrom scrapling.spiders import Spider, SessionManager, Request, Response\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession\n\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n max_blocked_retries = 5\n\n def configure_sessions(self, manager: SessionManager) -> None:\n manager.add('requests', FetcherSession(impersonate=['chrome', 'firefox', 'safari']))\n manager.add('stealth', AsyncStealthySession(block_webrtc=True), lazy=True)\n\n async def retry_blocked_request(self, request: Request, response: Response) -> Request:\n request.sid = \"stealth\"\n self.logger.info(f\"Retrying blocked request: {request.url}\")\n return request\n\n async def parse(self, response: Response):\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\nWhat happened above is that I left the blocking detection logic unchanged and had the spider mainly use requests until it got blocked, then switch to the stealthy browser.\n\n\nPutting it all together:\n\n```python\nfrom scrapling.spiders import Spider, SessionManager, Request, Response\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession, ProxyRotator\n\n\ncheap_proxies = ProxyRotator([ \"http://proxy1:8080\", \"http://proxy2:8080\"])\n\n# A format acceptable by the browser\nexpensive_proxies = ProxyRotator([\n {\"server\": \"http://residential_proxy1:8080\", \"username\": \"user\", \"password\": \"pass\"},\n {\"server\": \"http://residential_proxy2:8080\", \"username\": \"user\", \"password\": \"pass\"},\n {\"server\": \"http://mobile_proxy1:8080\", \"username\": \"user\", \"password\": \"pass\"},\n {\"server\": \"http://mobile_proxy2:8080\", \"username\": \"user\", \"password\": \"pass\"},\n])\n\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n max_blocked_retries = 5\n\n def configure_sessions(self, manager: SessionManager) -> None:\n manager.add('requests', FetcherSession(impersonate=['chrome', 'firefox', 'safari'], proxy_rotator=cheap_proxies))\n manager.add('stealth', AsyncStealthySession(block_webrtc=True, proxy_rotator=expensive_proxies), lazy=True)\n\n async def retry_blocked_request(self, request: Request, response: Response) -> Request:\n request.sid = \"stealth\"\n self.logger.info(f\"Retrying blocked request: {request.url}\")\n return request\n\n async def parse(self, response: Response):\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\nThe above logic is: requests are made with cheap proxies, such as datacenter proxies, until they are blocked, then retried with higher-quality proxies, such as residential or mobile proxies." }, { "path": "docs/spiders/requests-responses.md", "content": "# Requests & Responses\n\n!!! success \"Prerequisites\"\n\n 1. You've read the [Getting started](getting-started.md) page and know how to create and run a basic spider.\n\nThis page covers the `Request` object in detail โ€” how to construct requests, pass data between callbacks, control priority and deduplication, and use `response.follow()` for link-following.\n\n## The Request Object\n\nA `Request` represents a URL to be fetched. You create requests either directly or via `response.follow()`:\n\n```python\nfrom scrapling.spiders import Request\n\n# Direct construction\nrequest = Request(\n \"https://example.com/page\",\n callback=self.parse_page,\n priority=5,\n)\n\n# Via response.follow (preferred in callbacks)\nrequest = response.follow(\"/page\", callback=self.parse_page)\n```\n\nHere are all the arguments you can pass to `Request`:\n\n| Argument | Type | Default | Description |\n|---------------|------------|------------|-------------------------------------------------------------------------------------------------------|\n| `url` | `str` | *required* | The URL to fetch |\n| `sid` | `str` | `\"\"` | Session ID โ€” routes the request to a specific session (see [Sessions](sessions.md)) |\n| `callback` | `callable` | `None` | Async generator method to process the response. Defaults to `parse()` |\n| `priority` | `int` | `0` | Higher values are processed first |\n| `dont_filter` | `bool` | `False` | If `True`, skip deduplication (allow duplicate requests) |\n| `meta` | `dict` | `{}` | Arbitrary metadata passed through to the response |\n| `**kwargs` | | | Additional keyword arguments passed to the session's fetch method (e.g., `headers`, `method`, `data`) |\n\nAny extra keyword arguments are forwarded directly to the underlying session. For example, to make a POST request:\n\n```python\nyield Request(\n \"https://example.com/api\",\n method=\"POST\",\n data={\"key\": \"value\"},\n callback=self.parse_result,\n)\n```\n\n## Response.follow()\n\n`response.follow()` is the recommended way to create follow-up requests inside callbacks. It offers several advantages over constructing `Request` objects directly:\n\n- **Relative URLs** are resolved automatically against the current page URL\n- **Referer header** is set to the current page URL by default\n- **Session kwargs** from the original request are inherited (headers, proxy settings, etc.)\n- **Callback, session ID, and priority** are inherited from the original request if not specified\n\n```python\nasync def parse(self, response: Response):\n # Minimal โ€” inherits callback, sid, priority from current request\n yield response.follow(\"/next-page\")\n\n # Override specific fields\n yield response.follow(\n \"/product/123\",\n callback=self.parse_product,\n priority=10,\n )\n\n # Pass additional metadata to\n yield response.follow(\n \"/details\",\n callback=self.parse_details,\n meta={\"category\": \"electronics\"},\n )\n```\n\n| Argument | Type | Default | Description |\n|--------------------|------------|------------|------------------------------------------------------------|\n| `url` | `str` | *required* | URL to follow (absolute or relative) |\n| `sid` | `str` | `\"\"` | Session ID (inherits from original request if empty) |\n| `callback` | `callable` | `None` | Callback method (inherits from original request if `None`) |\n| `priority` | `int` | `None` | Priority (inherits from original request if `None`) |\n| `dont_filter` | `bool` | `False` | Skip deduplication |\n| `meta` | `dict` | `None` | Metadata (merged with existing response meta) |\n| **`referer_flow`** | `bool` | `True` | Set current URL as Referer header |\n| `**kwargs` | | | Merged with original request's session kwargs |\n\n### Disabling Referer Flow\n\nBy default, `response.follow()` sets the `Referer` header to the current page URL. To disable this:\n\n```python\nyield response.follow(\"/page\", referer_flow=False)\n```\n\n## Callbacks\n\nCallbacks are async generator methods on your spider that process responses. They must `yield` one of three types:\n\n- **`dict`** โ€” A scraped item, added to the results\n- **`Request`** โ€” A follow-up request, added to the queue\n- **`None`** โ€” Silently ignored\n\n```python\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n\n async def parse(self, response: Response):\n # Yield items (dicts)\n yield {\"url\": response.url, \"title\": response.css(\"title::text\").get(\"\")}\n\n # Yield follow-up requests\n for link in response.css(\"a::attr(href)\").getall():\n yield response.follow(link, callback=self.parse_page)\n\n async def parse_page(self, response: Response):\n yield {\"content\": response.css(\"article::text\").get(\"\")}\n```\n\n!!! tip \"Note:\"\n\n All callback methods must be `async def` and use `yield` (not `return`). Even if a callback only yields items with no follow-up requests, it must still be an async generator.\n\n## Request Priority\n\nRequests with higher priority values are processed first. This is useful when some pages are more important to be processed first before others:\n\n```python\nasync def parse(self, response: Response):\n # High priority โ€” process product pages first\n for link in response.css(\"a.product::attr(href)\").getall():\n yield response.follow(link, callback=self.parse_product, priority=10)\n\n # Low priority โ€” pagination links processed after products\n next_page = response.css(\"a.next::attr(href)\").get()\n if next_page:\n yield response.follow(next_page, callback=self.parse, priority=0)\n```\n\nWhen using `response.follow()`, the priority is inherited from the original request unless you specify a new one.\n\n## Deduplication\n\nThe spider automatically deduplicates requests based on a fingerprint computed from the URL, HTTP method, request body, and session ID. If two requests produce the same fingerprint, the second one is silently dropped.\n\nTo allow duplicate requests (e.g., re-visiting a page after login), set `dont_filter=True`:\n\n```python\nyield Request(\"https://example.com/dashboard\", dont_filter=True, callback=self.parse_dashboard)\n\n# Or with response.follow\nyield response.follow(\"/dashboard\", dont_filter=True, callback=self.parse_dashboard)\n```\n\nYou can fine-tune what goes into the fingerprint using class attributes on your spider:\n\n| Attribute | Default | Effect |\n|----------------------|---------|-----------------------------------------------------------------------------------------------------------------|\n| `fp_include_kwargs` | `False` | Include extra request kwargs (arguments you passed to the session fetch, like headers, etc.) in the fingerprint |\n| `fp_keep_fragments` | `False` | Keep URL fragments (`#section`) when computing fingerprints |\n| `fp_include_headers` | `False` | Include request headers in the fingerprint |\n\nFor example, if you need to treat `https://example.com/page#section1` and `https://example.com/page#section2` as different URLs:\n\n```python\nclass MySpider(Spider):\n name = \"my_spider\"\n fp_keep_fragments = True\n # ...\n```\n\n## Request Meta\n\nThe `meta` dictionary lets you pass arbitrary data between callbacks. This is useful when you need context from one page to process another:\n\n```python\nasync def parse(self, response: Response):\n for product in response.css(\"div.product\"):\n category = product.css(\"span.category::text\").get(\"\")\n link = product.css(\"a::attr(href)\").get()\n if link:\n yield response.follow(\n link,\n callback=self.parse_product,\n meta={\"category\": category},\n )\n\nasync def parse_product(self, response: Response):\n yield {\n \"name\": response.css(\"h1::text\").get(\"\"),\n \"price\": response.css(\".price::text\").get(\"\"),\n # Access meta from the request\n \"category\": response.meta.get(\"category\", \"\"),\n }\n```\n\nWhen using `response.follow()`, the meta from the current response is merged with the new meta you provide (new values take precedence).\n\nThe spider system also automatically stores some metadata. For example, the proxy used for a request is available as `response.meta[\"proxy\"]` when proxy rotation is enabled." }, { "path": "docs/spiders/sessions.md", "content": "# Spiders sessions\n\n!!! success \"Prerequisites\"\n\n 1. You've read the [Getting started](getting-started.md) page and know how to create and run a basic spider.\n 2. You're familiar with [Fetchers basics](../fetching/choosing.md) and the differences between HTTP, Dynamic, and Stealthy sessions.\n\nA spider can use multiple fetcher sessions simultaneously โ€” for example, a fast HTTP session for simple pages and a stealth browser session for protected pages. This page shows you how to configure and use sessions.\n\n## What are Sessions?\n\nAs you should already know, a session is a pre-configured fetcher instance that stays alive for the duration of the crawl. Instead of creating a new connection or browser for every request, the spider reuses sessions, which is faster and more resource-efficient.\n\nBy default, every spider creates a single [FetcherSession](../fetching/static.md). You can add more sessions or swap the default by overriding the `configure_sessions()` method, but you have to use the async version of each session only, as the table shows below:\n\n\n| Session Type | Use Case |\n|-------------------------------------------------|------------------------------------------|\n| [FetcherSession](../fetching/static.md) | Fast HTTP requests, no JavaScript |\n| [AsyncDynamicSession](../fetching/dynamic.md) | Browser automation, JavaScript rendering |\n| [AsyncStealthySession](../fetching/stealthy.md) | Anti-bot bypass, Cloudflare, etc. |\n\n\n## Configuring Sessions\n\nOverride `configure_sessions()` on your spider to set up sessions. The `manager` parameter is a `SessionManager` instance โ€” use `manager.add()` to register sessions:\n\n```python\nfrom scrapling.spiders import Spider, Response\nfrom scrapling.fetchers import FetcherSession\n\nclass MySpider(Spider):\n name = \"my_spider\"\n start_urls = [\"https://example.com\"]\n\n def configure_sessions(self, manager):\n manager.add(\"default\", FetcherSession())\n\n async def parse(self, response: Response):\n yield {\"title\": response.css(\"title::text\").get(\"\")}\n```\n\nThe `manager.add()` method takes:\n\n| Argument | Type | Default | Description |\n|--------------|-----------|------------|----------------------------------------------|\n| `session_id` | `str` | *required* | A name to reference this session in requests |\n| `session` | `Session` | *required* | The session instance |\n| `default` | `bool` | `False` | Make this the default session |\n| `lazy` | `bool` | `False` | Start the session only when first used |\n\n!!! note \"Notes:\"\n\n 1. In all requests, if you don't specify which session to use, the default session is used. The default session is determined in one of two ways:\n 1. The first session you add to the managed becomes the default automatically.\n 2. The session that gets `default=True` while added to the manager.\n 2. The instances you pass of each session don't have to be already started by you; the spider checks on all sessions if they are not already started and starts them.\n 3. If you want a specific session to start when used only, then use the `lazy` argument while adding that session to the manager. Example: start the browser only when you need it, not with the spider start.\n\n## Multi-Session Spider\n\nHere's a practical example: use a fast HTTP session for listing pages and a stealth browser for detail pages that have bot protection:\n\n```python\nfrom scrapling.spiders import Spider, Response\nfrom scrapling.fetchers import FetcherSession, AsyncStealthySession\n\nclass ProductSpider(Spider):\n name = \"products\"\n start_urls = [\"https://shop.example.com/products\"]\n\n def configure_sessions(self, manager):\n # Fast HTTP for listing pages (default)\n manager.add(\"http\", FetcherSession())\n\n # Stealth browser for protected product pages\n manager.add(\"stealth\", AsyncStealthySession(\n headless=True,\n network_idle=True,\n ))\n\n async def parse(self, response: Response):\n for link in response.css(\"a.product::attr(href)\").getall():\n # Route product pages through the stealth session\n yield response.follow(link, sid=\"stealth\", callback=self.parse_product)\n\n next_page = response.css(\"a.next::attr(href)\").get()\n if next_page:\n yield response.follow(next_page)\n\n async def parse_product(self, response: Response):\n yield {\n \"name\": response.css(\"h1::text\").get(\"\"),\n \"price\": response.css(\".price::text\").get(\"\"),\n }\n```\n\nThe key is the `sid` parameter โ€” it tells the spider which session to use for each request. When you call `response.follow()` without `sid`, the session ID from the original request is inherited.\n\nNote that the sessions don't have to be from different classes only, but can be the same session, but different instances with different configurations, for example, like below:\n\n```python\nfrom scrapling.spiders import Spider, Response\nfrom scrapling.fetchers import FetcherSession\n\nclass ProductSpider(Spider):\n name = \"products\"\n start_urls = [\"https://shop.example.com/products\"]\n\n def configure_sessions(self, manager):\n chrome_requests = FetcherSession(impersonate=\"chrome\")\n firefox_requests = FetcherSession(impersonate=\"firefox\")\n\n manager.add(\"chrome\", chrome_requests)\n manager.add(\"firefox\", firefox_requests)\n\n async def parse(self, response: Response):\n for link in response.css(\"a.product::attr(href)\").getall():\n yield response.follow(link, callback=self.parse_product)\n\n next_page = response.css(\"a.next::attr(href)\").get()\n if next_page:\n yield response.follow(next_page, sid=\"firefox\")\n\n async def parse_product(self, response: Response):\n yield {\n \"name\": response.css(\"h1::text\").get(\"\"),\n \"price\": response.css(\".price::text\").get(\"\"),\n }\n```\n\nOr you can separate concerns and keep a session with its cookies/state for specific requests, etc...\n\n## Session Arguments\n\nExtra keyword arguments passed to a `Request` (or through `response.follow(**kwargs)`) are forwarded to the session's fetch method. This lets you customize individual requests without changing the session configuration:\n\n```python\nasync def parse(self, response: Response):\n # Pass extra headers for this specific request\n yield Request(\n \"https://api.example.com/data\",\n headers={\"Authorization\": \"Bearer token123\"},\n callback=self.parse_api,\n )\n\n # Use a different HTTP method\n yield Request(\n \"https://example.com/submit\",\n method=\"POST\",\n data={\"field\": \"value\"},\n sid=\"firefox\",\n callback=self.parse_result,\n )\n```\n\n!!! warning\n\n Normally, when you use `FetcherSession`, `Fetcher`, or `AsyncFetcher`, you specify the HTTP method to use with the corresponding method like `.get()` and `.post()`. But while using `FetcherSession` in spiders, you can't do this. By default, the request is an _HTTP GET_ request; if you want to use another HTTP method, you have to pass it to the `method` argument, as in the above example. The reason for this is to unify the `Request` interface across all session types.\n\nFor browser sessions (`AsyncDynamicSession`, `AsyncStealthySession`), you can pass browser-specific arguments like `wait_selector`, `page_action`, or `extra_headers`:\n\n```python\nasync def parse(self, response: Response):\n # Use Cloudflare solver with the `AsyncStealthySession` we configured above\n yield Request(\n \"https://nopecha.com/demo/cloudflare\",\n sid=\"stealth\",\n callback=self.parse_result,\n solve_cloudflare=True,\n block_webrtc=True,\n hide_canvas=True,\n google_search=True,\n )\n\n yield response.follow(\n \"/dynamic-page\",\n sid=\"browser\",\n callback=self.parse_dynamic,\n wait_selector=\"div.loaded\",\n network_idle=True,\n )\n```\n\n!!! warning\n\n Session arguments (**kwargs) passed from the original request are inherited by `response.follow()`. New kwargs take precedence over inherited ones.\n\n```python\nfrom scrapling.spiders import Spider, Response\nfrom scrapling.fetchers import FetcherSession\n\nclass ProductSpider(Spider):\n name = \"products\"\n start_urls = [\"https://shop.example.com/products\"]\n\n def configure_sessions(self, manager):\n manager.add(\"http\", FetcherSession(impersonate='chrome'))\n\n async def parse(self, response: Response):\n # I don't want the follow request to impersonate a desktop Chrome like the previous request, but a mobile one\n # so I override it like this\n for link in response.css(\"a.product::attr(href)\").getall():\n yield response.follow(link, impersonate=\"chrome131_android\", callback=self.parse_product)\n\n next_page = response.css(\"a.next::attr(href)\").get()\n if next_page:\n yield Request(next_page)\n\n async def parse_product(self, response: Response):\n yield {\n \"name\": response.css(\"h1::text\").get(\"\"),\n \"price\": response.css(\".price::text\").get(\"\"),\n }\n```\n!!! info\n\n No need to mention that, upon spider closure, the manager automatically checks whether any sessions are still running and closes them before closing the spider." }, { "path": "docs/stylesheets/extra.css", "content": ".md-grid {\n max-width: 90%;\n}\n\n@font-face {\n font-family: 'Maple Mono';\n font-style: normal;\n font-display: swap;\n font-weight: 400;\n src: url(https://cdn.jsdelivr.net/fontsource/fonts/maple-mono@latest/latin-400-normal.woff2) format('woff2'), url(https://cdn.jsdelivr.net/fontsource/fonts/maple-mono@latest/latin-400-normal.woff) format('woff');\n}\n\n:root {\n --md-code-font: 'Maple Mono';\n}\n[align=\"center\"] code {\n font-family: 'Maple Mono';\n font-style: italic;\n font-weight: 800;\n}\n\n/* Announcement banner background */\n[data-md-color-scheme=\"default\"] .md-banner {\n background-color: #232946;\n}\n\n[data-md-color-scheme=\"slate\"] .md-banner {\n background-color: #141428;\n}" }, { "path": "docs/tutorials/migrating_from_beautifulsoup.md", "content": "# Migrating from BeautifulSoup to Scrapling\n\nIf you're already familiar with BeautifulSoup, you're in for a treat.

This guide will help you quickly adapt your existing BeautifulSoup code to leverage Scrapling's capabilities.\n\nBelow is a table that covers the most common operations you'll perform when scraping web pages. Each row illustrates how to achieve a specific task using BeautifulSoup and the corresponding method in Scrapling.\n\nYou will notice that some shortcuts in BeautifulSoup are missing in Scrapling, which is one of the reasons BeautifulSoup is slower than Scrapling. The point is: If the same feature can be used in a short one-liner, there is no need to sacrifice performance to shorten that short line :)\n\n\n| Task | BeautifulSoup Code | Scrapling Code

'story').filter(lambda p: p.tag == 'a')` |\n\n\nยน **Note:** BS4's `find_previous`/`find_all_previous` searches all preceding elements in document order, while Scrapling's `path` only returns ancestors (the parent chain). These are not exact equivalents, but ancestor search covers the most common use case.\n\n**One key point to remember**: BeautifulSoup offers features for modifying and manipulating the page after it has been parsed. Scrapling focuses more on scraping the page faster for you, and then you can do what you want with the extracted information. So, two different tools can be used in Web Scraping, but one of them specializes in Web Scraping :)\n\n### Putting It All Together\n\nHere's a simple example of scraping a web page to extract all the links using BeautifulSoup and Scrapling.\n\n**With BeautifulSoup:**\n\n```python\nimport requests\nfrom bs4 import BeautifulSoup\n\nurl = 'https://example.com'\nresponse = requests.get(url)\nsoup = BeautifulSoup(response.text, 'html.parser')\n\nlinks = soup.find_all('a')\nfor link in links:\n print(link['href'])\n```\n\n**With Scrapling:**\n\n```python\nfrom scrapling import Fetcher\n\nurl = 'https://example.com'\npage = Fetcher.get(url)\n\nlinks = page.css('a::attr(href)')\nfor link in links:\n print(link)\n```\n\nAs you can see, Scrapling simplifies the process by combining fetching and parsing into a single step, making your code cleaner and more efficient.\n\n!!! abstract \"**Additional Notes:**\"\n\n - **Different parsers**: BeautifulSoup allows you to set the parser engine to use, and one of them is `lxml`. Scrapling doesn't do that and uses the `lxml` library by default for performance reasons.\n - **Element Types**: In BeautifulSoup, elements are `Tag` objects; in Scrapling, they are `Selector` objects. However, they provide similar methods and properties for navigation and data extraction.\n - **Error Handling**: Both libraries return `None` when an element is not found (e.g., `soup.find()` or `page.find()`). In Scrapling, `page.css()` returns an empty `Selectors` list when no elements match, and you can use `page.css('.foo').first` to safely get the first match or `None`. To avoid errors, check for `None` or empty results before accessing properties.\n - **Text Extraction**: Scrapling provides additional methods for handling text through `TextHandler`, such as `clean()`, which can help remove extra whitespace, consecutive spaces, or unwanted characters. Please check out the documentation for the complete list.\n\nThe documentation provides more details on Scrapling's features and the complete list of arguments that can be passed to all methods.\n\nThis guide should make your transition from BeautifulSoup to Scrapling smooth and straightforward. Happy scraping!" }, { "path": "docs/tutorials/replacing_ai.md", "content": "# Scrapling: A Free Alternative to AI for Robust Web Scraping\n\nWeb scraping has long been a vital tool for data extraction, indexing, and preparing datasets, among other purposes. But experienced users often encounter persistent issues that can hinder effectiveness. Recently, there's been a noticeable shift toward AI-based web scraping, driven by its potential to address these challenges.\n\nIn this article, we will discuss these common issues, why companies are shifting toward that approach, the problems with that approach, and how scrapling solves them for you without the cost of using AI.\n\n## Common issues and challenging goals\n\nIf you have been doing Web Scraping for a long time, you probably noticed that there are repeating problems with Web Scraping, like:\n\n1. **Rapidly changing website structures** โ€” Sites frequently update their DOM structures, breaking static XPath/CSS selectors.\n2. **Unstable selectors** โ€” Class names and IDs often change or use randomly generated values that break scrapers or make scraping these websites difficult.\n3. **Increasingly complex anti-bot measures** โ€” CAPTCHA systems, browser fingerprinting, and behavior analysis make traditional scraping difficult\nand others\n\nBut that's only if you are doing targeted Web Scraping for known websites, in which case you can write specific code for every website.\n\nIf you start thinking about bigger goals like Broad Scraping or Generic Web Scraping, or what you like to call it, then the above issues intensify, and you will face new issues like:\n\n1. **Extreme Website Diversity** โ€” Generic scraping must handle countless variations in HTML structures, CSS usage, JavaScript frameworks, and backend technologies.\n2. **Identifying Relevant Data** โ€” How does the scraper know what data is important on a page it has never seen before?\n3. **Pagination variations** โ€” Infinite scroll, traditional pagination, \"load more\" buttons, all requiring different approaches\nand more\n\nHow will you solve that manually? I'm referring to generic web scraping of various websites that don't share any common technologies.\n\n## AI to the rescue, but at a high cost\n\nOf course, AI can easily solve most of these issues because it can understand the page source and identify the fields you want or create selectors for them. That's, of course, if you already solved the anti-bot measures through other tools :)\n\nThis approach is, of course, beautiful. I love AI and find it very fascinating, especially Generative AI. You will probably spend a lot of time on prompt engineering and tweaking the prompts, but if that's cool with you, you will soon hit the real issue with using AI here.\n\nMost websites have vast amounts of content per page, which you will need to pass to the AI somehow so it can do its magic. This will burn through tokens like fire in a haystack, quickly accumulating high costs.\n\nUnless money is irrelevant to you, you will try to find less expensive approaches, and that's where Scrapling comes into play :smile:\n\n## Scrapling got you covered\n\nScrapling can handle almost all issues you will face during Web Scraping, and the following updates will cover the rest carefully.\n\n### Solving issue T1: Rapidly changing website structures\nThat's why the [adaptive](https://scrapling.readthedocs.io/en/latest/parsing/adaptive.html) feature was made. You knew I would talk about it, and here we are :)\n\nWhile Web Scraping, if you have the `adaptive` feature enabled, you can save any element's unique properties so you can find it again later when the website's structure changes. The most frustrating thing about changes is that anything about an element can change, so there's nothing to rely on. \n\nThat's how the adaptive feature works: it stores everything unique about an element. When the website structure changes, it returns the element with the highest similarity score of the previous element.\n\nI have already explained this in more detail, with many examples. Read more from [here](https://scrapling.readthedocs.io/en/latest/parsing/adaptive.html#how-the-adaptive-feature-works).\n\n### Solving issue T2: Unstable selectors\nIf you have been doing Web scraping for a long enough time, you have likely experienced this once. I'm referring to a website that employs poor design patterns, built on raw HTML without any IDs/classes, or uses random class names with nothing else to rely on, etc...\n\nIn these cases, standard selection methods with CSS/XPath selectors won't be optimal, and that's why Scrapling provides three more methods for Selection:\n\n1. [Selection by element content](https://scrapling.readthedocs.io/en/latest/parsing/selection.html#text-content-selection): Through text content (`find_by_text`) or regex that matches text content (`find_by_regex`)\n2. [Selecting elements similar to another element](https://scrapling.readthedocs.io/en/latest/parsing/selection.html#finding-similar-elements): You find an element, and we will do the rest!\n3. [Selecting elements by filters](https://scrapling.readthedocs.io/en/latest/parsing/selection.html#filters-based-searching): You specify conditions/filters that this element must fulfill, we find it!\n\nThere is no need to explain any of these; click on the links, and it will be clear how Scrapling solves this.\n\n### Solving issue T3: Increasingly complex anti-bot measures\nIt's well known that creating an undetectable spider requires more than residential/mobile proxies and human-like behavior. It also needs a hard-to-detect browser, which Scrapling provides two main options to solve:\n\n1. [DynamicFetcher](https://scrapling.readthedocs.io/en/latest/fetching/dynamic.html) โ€” This fetcher provides flexible browser automation with multiple configuration options and little under-the-hood stealth improvements.\n2. [StealthyFetcher](https://scrapling.readthedocs.io/en/latest/fetching/stealthy.html) โ€” Because we live in a harsh world and you need to take [full measure instead of half-measures](https://www.youtube.com/watch?v=7BE4QcwX4dU), `StealthyFetcher` was born. This fetcher uses our stealthy browser -- a version of [DynamicFetcher](https://scrapling.readthedocs.io/en/latest/fetching/dynamic.html) that nearly bypasses all annoying anti-protections, provides tools to handle the rest, and automatically bypasses all types of Cloudflare's Turnstile/Interstitial!\n\nWe keep improving these two with each update, so stay tuned :)\n\n### Solving issues B1 & B2: Extreme Website Diversity / Identifying Relevant Data\n\nThis one is tough to handle, but Scrapling's flexibility makes it possible. \n\nI talked with someone who uses AI to extract prices from different websites. He is only interested in prices and titles, so he uses AI to find the price for him.\n\nI told him you don't need to use AI here and gave this code as an example\n```python\nprice_element = page.find_by_regex(r'ยฃ[\\d\\.,]+', first_match=True) # Get the first element that contains a text that matches price regex eg. ยฃ10.50\n# If you want the container/element that contains the price element\nprice_element_container = price_element.parent or price_element.find_ancestor(lambda ancestor: ancestor.has_class('product')) # or other methods...\ntarget_element_selector = price_element_container.generate_css_selector or price_element_container.generate_full_css_selector # or xpath\n```\nThen he said What about cases like this:\n```html\n<span class='currency'> $ </span> <span class='a-price'> 45,000 </span>\n```\nSo, I updated the code like this\n```python\nprice_element_container = page.find_by_regex(r'[\\d,]+', first_match=True).parent # Adjusted the regex for this example\nfull_price_data = price_element_container.get_all_text(strip=True) # Returns '$45,000' in this case\n```\nThis was enough for his use case. You can use the first regex, and if it doesn't find anything, use the following regex, and so on. Try to cover the most common patterns first, then the less common ones, and so on.\nIt will be a bit boring, but it's definitely less expensive than AI.\n\nThis example illustrates the point I aim to convey here. Not every challenge will need AI to be solved, but sometimes you need to be creative, and that might save you a lot of money.\n\n### Solving issue B3: Pagination variations\nThis issue, Scrapling currently doesn't have a direct method to automatically extract pagination's URLs for you, but it will be added with the upcoming updates :)\n\nBut you can handle most websites if you search for the most common patterns with `page.find_by_text('Next')['href']` or `page.find_by_text('load more')['href']` or selectors like `'a[href*=\"?page=\"]'` or `'a[href*=\"/page/\"]'`โ€”you get the idea.\n\n## Cost Comparison and Savings\nFor a quick comparison.\n\n| Aspect | Scrapling | AI-Based Tools (e.g., Browse AI, Oxylabs) |\n|----------------|----------------------------------------------------------------------------|----------------------------------------------------------------------------|\n| Cost Structure | Likely free or low-cost, no per-use fees | Starts at $19/month (Browse AI) to $49/month (Oxylabs), scales with usage |\n| Setup Effort | Requires little technical expertise, manual setup | Often no-code, easier for non-technical users |\n| Usage options | Through code, terminal, or MCP server. | Often through GUI or API, depending on the option the company is providing |\n| Scalability | Depends on user implementation | Built-in support for large-scale, managed services |\n| Adaptability | High with features like `adaptive` and the non-selectors selection methods | High, automatic with AI, but costly for frequent changes |\n\nThis table is based on pricing from [Browse AI Pricing](https://www.browse.ai/pricing) and [Oxylabs Web Scraper API Pricing](https://oxylabs.io/products/scraper-api/web/pricing)\n\n## Conclusion\nWhile AI offers powerful capabilities, its cost can be prohibitive for many Web scraping tasks. Scrapling provides a robust, flexible, and cost-effective toolkit for tackling the real-world challenges of both targeted and broad scraping, often eliminating the need for expensive AI solutions. You can build resilient scrapers more efficiently by leveraging features like `adaptive`, diverse selection methods, and advanced fetchers.\n\nExplore the documentation further and see how Scrapling can simplify your future Web Scraping projects!" }, { "path": "pyproject.toml", "content": "[build-system]\nrequires = [\"setuptools>=61.0\", \"wheel\"]\nbuild-backend = \"setuptools.build_meta\"\n\n[project]\nname = \"scrapling\"\n# Static version instead of a dynamic version so we can get better layer caching while building docker, check the docker file to understand\nversion = \"0.4.2\"\ndescription = \"Scrapling is an undetectable, powerful, flexible, high-performance Python library that makes Web Scraping easy and effortless as it should be!\"\nreadme = {file = \"README.md\", content-type = \"text/markdown\"}\nlicense = {file = \"LICENSE\"}\nauthors = [\n {name = \"Karim Shoair\", email = \"karim.shoair@pm.me\"}\n]\nmaintainers = [\n {name = \"Karim Shoair\", email = \"karim.shoair@pm.me\"}\n]\nkeywords = [\n \"web-scraping\",\n \"scraping\",\n \"automation\",\n \"browser-automation\",\n \"data-extraction\",\n \"html-parsing\",\n \"undetectable\",\n \"playwright\",\n \"selenium-alternative\",\n \"web-crawler\",\n \"browser\",\n \"crawling\",\n \"headless\",\n \"scraper\",\n \"chrome\",\n]\nrequires-python = \">=3.10\"\nclassifiers = [\n \"Operating System :: OS Independent\",\n \"Development Status :: 4 - Beta\",\n #
