lxml is the most feature-rich and easy-to-use library for processing XML and HTML in Python. It combines the speed and XML feature completeness of the C libraries libxml2 and libxslt with the simplicity of a native Python API, mostly compatible but superior to the well-known ElementTree API. lxml is unique in providing both high performance and comprehensive XML/HTML processing capabilities, making it the go-to choice for developers working with structured markup data.
This compiler includes lxml with full support for XML and HTML parsing, XPath queries, XSLT transformations, and ElementTree API compatibility, all powered by Pyodide WebAssembly technology. The platform supports all core lxml features including parsing XML and HTML from strings or files, navigating and modifying element trees, XPath expressions for powerful element selection, XSLT stylesheet transformations, validation with DTD, RelaxNG, and XML Schema, and HTML-specific methods for working with web content. You can also upload and use files or folders directly in your code for XML/HTML processing workflows. This compiler is online and completely free to use.
Our comprehensive example collection covers essential XML and HTML processing techniques including basic XML parsing and element access, HTML parsing with lxml.html, XPath queries for advanced element selection, creating and modifying XML documents, working with namespaces, HTML element methods for web scraping, and XSLT transformations. You'll also learn how to validate XML documents, extract data from complex structures, and handle both well-formed and malformed HTML content commonly found in real-world web processing scenarios.
