[xslt] Python extension functions -- accessing args

[Phil Frost <indigo unununium org>]

I've been trying to write some extension functions using python, and
I've been unable to learn how to access the parameters of the function
when the parameter is a node. For example, i can process fu('bar'), but
when i try fu(/doc/bar) I'm not sure how to get at the contents of the
"bar" element. Attached is a minimal program which demonstrates the
problem. As I can tell, if the parameter is a node, returned is a
PyCObject which looks like a list with one child PyCObject with no
methods. Any help is much appreciated.
