lxml 4.5.2

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.

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-4.5 . Running easy_install lxml==4.5bugfix will install the unreleased branch state from https://github.com/lxml/lxml/tarball/lxml-4.5#egg=lxml-4.5bugfix as soon as a maintenance branch has been established. Note that this requires Cython to be installed at an appropriate version for the build.

4.5.2 (2020-07-09)

Bugs fixed

• Cleaner() now validates that only known configuration options can be set.

• LP#1882606: Cleaner.clean_html() discarded comments and PIs regardless of the corresponding configuration option, if remove_unknown_tags was set.

• LP#1880251: Instead of globally overwriting the document loader in libxml2, lxml now sets it per parser run, which improves the interoperability with other users of libxml2 such as libxmlsec.

• LP#1881960: Fix build in CPython 3.10 by using Cython 0.29.21.

• The setup options “–with-xml2-config” and “–with-xslt-config” were accidentally renamed to “–xml2-config” and “–xslt-config” in 4.5.1 and are now available again.
