Thanks for the pointer which gave me the missing pieces for my HTML 
problem :-)

I have a couple of related questions...

1) What is the link between the libxml2-python and the python bindings 
available under libxml2 and libxslt? They seem to be close if not 
identical...

2) How do you register EXSLT extensions in python? I have seen in a 
comment of pyxsltproc.py that:

# TODO libxslt.exsltRegisterAll();

However, a naive:

libxslt.registerExtModuleFunction("node-set", "http://exslt.org/common";, 
libxslt.libxsltmod.xsltFunctionNodeSet)

gives a run time error. What's the correct way to register these functions?

Thanks

Eric
