  Actually, there is a serialize() method associated to any DOM
node taking care of this in a better way. Look at the serialize.py
test case in libxml/python/tests directory, the API is quite better
since it allows to indent or save to a given encoding.

  Right, the serialize() extension was provided after I wrote
    http://xmlsoft.org/python.html

  Well, that's yet another part needing fixups at the bindings level,
first saveResultToXXX is better than calling serialize() on the document
resulting from the transformation since some of the attributes of the
transformations cannot be stored in the DOM tree (like indentation request).
Also the libxml2/libxslt I/O level doesn't work well with python I/Os at
the moment, a bit of glue with a python class providing direct access to the
Python I/O routines would help, but I hadn't time yet to do this.

  Dave's feedback and experience was integrated when developping the
"official" bindings, and I certainly had a look at his code especially
for the SAX mapping interfaces :-)
