Powerful and Pythonic XML processing library combining libxml2/libxslt with the ElementTree API.

Project description

lxml is a Pythonic, mature binding for the libxml2 and libxslt libraries. It provides safe and convenient access to these libraries using the ElementTree API.

It extends the ElementTree API significantly to offer support for XPath, RelaxNG, XML Schema, XSLT, C14N and much more.

To contact the project, go to the project home page or see our bug tracker at https://launchpad.net/lxml

In case you want to use the current in-development version of lxml, you can get it from the github repository at https://github.com/lxml/lxml . Note that this requires Cython to build the sources, see the build instructions on the project home page. To the same end, running easy_install lxml==dev will install lxml from https://github.com/lxml/lxml/tarball/master#egg=lxml-dev if you have an appropriate version of Cython installed.

After an official release of a new stable series, bug fixes may become available at https://github.com/lxml/lxml/tree/lxml-4.3 . Running easy_install lxml==4.3bugfix will install the unreleased branch state from https://github.com/lxml/lxml/tarball/lxml-4.3#egg=lxml-4.3bugfix as soon as a maintenance branch has been established. Note that this requires Cython to be installed at an appropriate version for the build.

4.3.0 (2019-01-04)

Features added

  • The module lxml.sax is compiled using Cython in order to speed it up.
  • GH#267: lxml.sax.ElementTreeProducer now preserves the namespace prefixes. If two prefixes point to the same URI, the first prefix in alphabetical order is used. Patch by Lennart Regebro.
  • Updated ISO-Schematron implementation to 2013 version (now MIT licensed) and the corresponding schema to the 2016 version (with optional “properties”).

Other changes

  • GH#270, GH#271: Support for Python 2.6 and 3.3 was removed. Patch by hugovk.
  • The minimum dependency versions were raised to libxml2 2.9.2 and libxslt 1.1.27, which were released in 2014 and 2012 respectively.
  • Built with Cython 0.29.2.
