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-2.3 . Running easy_install lxml==2.3bugfix will install the unreleased branch state from https://github.com/lxml/lxml/tarball/lxml-2.3#egg=lxml-2.3bugfix as soon as a maintenance branch has been established. Note that this requires Cython to be installed at an appropriate version for the build.
- lxml.html.tostring() gained new serialisation options with_tail and doctype.
- Fixed a crash when using iterparse() for HTML parsing and requesting start events.
- Fixed parsing of more selectors in cssselect. Whitespace before pseudo-elements and pseudo-classes is significant as it is a descendant combinator. “E :pseudo” should parse the same as “E *:pseudo”, not “E:pseudo”. Patch by Simon Sapin.
- lxml.html.diff no longer raises an exception when hitting ‘img’ tags without ‘src’ attribute.
