It seems pretty clear why DOM isn't Pythonic: it doesn't use Python's
standard APIs for things that conceptually are "just" lists and dicts,
or at least sequences and mappings. Also, the memory footprint is a
I don't think that SAX is unpythonic, but it's pretty low-level and
mostly of use to people writing higher-level XML parsers (my parsexml
module uses it).
