XPath and XQuery in Python?

[Nelson Minar]

Could someone help me get started using XPath or XQuery in Python? I'm
overwhelmed by all the various options and am lacking guidance on what
the simplest way to go is. What library do I need to enable three line
Python programs to extract data with XPath expressions?

I have this problem a lot with Python and XML. Even with Uche's
excellent yearly roundups I have a hard time finding how to do fancy
things with XML in Python. I think it's a bit like web server
frameworks in Python - too many choices.
