Absolutely! My favorite way is to use the minidom to construct an XML
document in memory, and then use node.toxml() to generate the content.
(You can also use toprettyxml() while you are debugging if you want it to
be readable.) The python documentation has lots of good information about
the available XML tools. I made a wrapper for the minidom that lets me use
simple operators to append nodes and traverse the tree.

Additionally, I sometimes find that it is easier to make an xml output
function in a particular class that builds an xml document from the class
dictionary.

Also, in some situations, it may make more sense just to write out the xml
code and replace parts of it with python:

"""
<doc>
  <test1 prop="%(test1prop)s"/>
</doc>
"""%{'test1prop':'asdf'}
