Ahh, I forgot about the Clark notation. Good to know, thanks! I'm so get used
to the prefix notation.

By the way, I think there is a small error in my patch: The variable namespaces
isn't correctly initialized. There should be a "parser.set_defaults(namespaces=[])"
before the "parser.add_option("-N", "--ns", ...)" line.

To spread the word about lxml and xpathgrep.py: I've wrote a small article here:

:-)

Thanks,
