IMO, generating XML is much simpler than parsing it - you normally
don't need any library. Hence, there is no explicit library support
for it.

If you absolutely think you need to create a DOM tree, you have to use
the normal DOM API for creation: use createDocument on the DOM
implementation, then use createElement on the document, and
appendChild to build the tree.

I recommend

print '<object name="%s" city="%s"><desc>%s</desc></object>' % \
   (object.name, object.city, object.desc)

Care is needed if the attributes may contain markup.
