benchmarking XML tools is hard, and is a great way to get lots of nasty
mails from people who don't know anything about software engineering,
but here are some parse-only figures for common Python XML parsers:

if your XML files are mostly regular (e.g. uses a record-like structure), I
doubt you can beat cElementTree's iterparse function:
