There's a good example of how to do this over at Kimbro Staken's weblog:

240_libxslt_Extension_Functions_in_Python.item

A couple of brief things to help: if the parameter is an xpath then a  
nodelist (if there's only one matching node then you get a single-item  
list) is passed in. The PyCObjects are 'raw' objects coming out of  
libxslt. The first thing you need to do is make them into proper  
libxslt/Python node objects: this is all explained in Kimbro's post.

You could also join the Python/XML mailing list: there are several  
other users of libxslt's python bindings there.

Best,

Matt
