Re: [Jython-users] Python XML parsers in Jython

[Sean M. <sea...@pr...>]

Matt,

I do a lot of XML work with Jython and find that re-using from the pool of excellent Java-based tools for XML parsing is a very powerful and simple way to go.

I use Xerces and Xalan giving me very high levels of standards compliance with full XPath 1.0 implementation etc.

In CPython some of the more comprehensive XML packages use C extensions for things like James Clark's expat, XPath grammers and so on. It is primarily these C/C++ extensions that cause problems making XML tools in CPython/Jython seamless.
