How to build lxml from source To build lxml from source, you need libxml2 and libxslt properly installed, including the header files. These are likely shipped in separate -dev or -devel packages like libxml2-dev, which you must install before trying to build lxml. Cython The lxml.etree and lxml.objectify modules are written in Cython. Since we distribute the Cython-generated .c files with lxml rel
XPath and XSLT with lxml lxml supports XPath 1.0, XSLT 1.0 and the EXSLT extensions through libxml2 and libxslt in a standards compliant way. lxml.etree supports the simple path syntax of the find, findall and findtext methods on ElementTree and Element, as known from the original ElementTree library (ElementPath). As an lxml specific extension, these classes also provide an xpath() method that su
Since version 2.0, lxml comes with a dedicated Python package for dealing with HTML: lxml.html. It is based on lxml's HTML parser, but provides a special Element API for HTML elements, as well as a number of utilities for common HTML processing tasks. Parsing HTML fragments There are several functions available to parse HTML: parse(filename_url_or_file): Parses the named file or url, or if the obj
APIs specific to lxml.etree lxml.etree tries to follow established APIs wherever possible. Sometimes, however, the need to expose a feature in an easy way led to the invention of a new API. This page describes the major differences and a few additions to the main ElementTree API. For a complete reference of the API, see the generated API documentation. Separate pages describe the support for parsi
This is a tutorial on XML processing with lxml.etree. It briefly overviews the main concepts of the ElementTree API, and some simple enhancements that make your life as a programmer easier. For a complete reference of the API, see the generated API documentation.
lxml is the most feature-rich and easy-to-use library for processing XML and HTML in the Python language. Introduction The lxml XML toolkit is a Pythonic binding for the C libraries libxml2 and libxslt. It is unique in that it combines the speed and XML feature completeness of these libraries with the simplicity of a native Python API, mostly compatible but superior to the well-known ElementTree A
