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.
ElementPath supports text predicates for current node, like “[.=’text’]”.
ElementPath allows spaces in predicates.
Custom Element classes and XPath functions can now be registered with a
decorator rather than explicit dict assignments.
Static Linux wheels are now built with link time optimisation (LTO) enabled.
This should have a beneficial impact on the overall performance by providing
a tighter compiler integration between lxml and libxml2/libxslt.
Bugs fixed
LP#1722776: Requesting non-Element objects like comments from a document with
PythonElementClassLookup could fail with a TypeError.
