In general, importing a package does not give access to members of a sub-package. You have to explicitly import the subpackage. For example, In [1]: import xml In [2]: xml.dom.Node --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) /Users/kent/<ipython console> in <module>() AttributeError: 'module' object has no attribute 'dom' In [3]: import xml.dom In [4]: xml.dom.Node Out[4]: <class xml.dom.Node at 0x149eba0> There are some exceptions, notably os.path: In [5]: import os In [6]: os.path Out[6]: <module 'posixpath' from '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/posixpath.pyc'> but that is a special case and requires special coding in the os module.
