xmppony is an XMPP library for Python. It's a fork of xmpppy, which was in turn a fork of jabber.py. It is currently a drop-in replacement for python-xmpp (xmpppy), with some bugs fixed and file transfer added.
FluentXML provides a simple interface to parse, create, query, edit, and save XML in a pythonic way. It was designed to be as simple and intuitive as possible, so you do not need to waste your time with a complicated and superfluous API.
