[lxml-dev] About lxml status

[Lee Brown]

Greetings!

This discussion reminded me of a question that I've been pondering: will the
XPATH support in LXML eventually include support for axes and predicates?

Also, congratulations on the thorough Xinclude support.  Other than 4Suite, LXML
is one of the few parsers that handle the "parse=" attribute and the "fallback"
elements correctly.

Note that the ElementTree API is a developing Python standard, implemented by 3
separate libraries, ElementTree, cElementTree and lxml. 
ElementTree and cElement have become part of the core Python distribution as of
Python 2.5.

A lot of ElementTree documentation can be found here:

You can do common DOM-style manipulations through this API, just in a more
convenient manner.

As to XPath and XSLT support, lxml has that, including the ability to create
extension functions and the like. There are differences in feature set here and
there, but overall lxml should be able to compete with 4Suite.

Regards,

Martijn
