I'm not sure why you would want to use a SAX parser for this. The advantage
of incremental parsing is that you never have to have the whole document in
memory at once. If you use it to construct some DOM-like structure from the
document, then you're going to have the whole document in memory anyway,
and you might as well just use one of the existing implementations (e.g.
ElementTree) rather than reinventing your own.
