It supports standard CSS selectors and some extended pseudo-classes (like `:lexbor-contains` for text matching), and exposes parsed nodes with methods to extract text, attributes, and HTML fragments. The package is designed for web scraping and data extraction tasks where parsing speed matters.\n\nThe library has no runtime dependencies and comes as pre-compiled wheels for modern Python versions (3.9\u20133.14) on major platforms. Installation is straightforward on supported configurations; older or edge-case Python versions may require building from source. The Lexbor backend is now preferred over Modest, which is maintained for backward compatibility only.","worth_installing":"Yes. selectolax is actively maintained, has no security vulnerabilities, uses a permissive MIT license, and offers a significant speed advantage over pure-Python HTML parsers for typical web-scraping tasks. Install friction is medium but manageable thanks to pre-built wheels. Choose it if parsing performance matters or if you need CSS selector support; it's a solid, production-ready choice for HTML extraction work."},"id":"selectolax","links":{"html":"https://skillfed.io/packages/selectolax","md":"https://skillfed.io/packages/selectolax.md","pypi":"https://pypi.org/project/selectolax/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-15","license_spdx":"MIT","license_treatment":"permissive","name":"selectolax","python_support":"supports_current","summary":"A fast HTML5 parser with CSS selectors, written in Cython, using Modest and Lexbor engines."},"popularity":{"monthly_downloads":6064384,"position":1976,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.4.11"}
