I recommend you pick an API which you already know from the
application level (e.g. SAX, DOM, XPath, xmlproc, ...). For that piece
of software, you take some example that uses this API. For that
example, you

1. find out what modules it uses, by printing sys.modules.keys() after
   all imports are done, and
2. put strategic print statements into those modules, to find out who
   calls what.
