Powerful and Pythonic XML processing library combining libxml2/libxslt with the ElementTree API.
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.
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-3.2 . Running easy_install lxml==3.2bugfix will install the unreleased branch state from https://github.com/lxml/lxml/tarball/lxml-3.2#egg=lxml-3.2bugfix as soon as a maintenance branch has been established. Note that this requires Cython to be installed at an appropriate version for the build.
- The methods apply_templates() and process_children() of XSLT extension elements have gained two new boolean options elements_only and remove_blank_text that discard either all strings or whitespace-only strings from the result list.
- When moving Elements to another tree, the namespace cleanup mechanism no longer drops namespace prefixes from attributes for which it finds a default namespace declaration, to prevent them from appearing as unnamespaced attributes after serialisation.
- Returning non-type objects from a custom class lookup method could lead to a crash.
- Instantiating and using subtypes of Comments and ProcessingInstructions crashed.
