I doubt you'll get as low a memory footprint.

It's probably not fair, but then, so what ? If pyRXP doesn't do what you 
need, just forget it, and use whatever parser you feel like using. I
personnaly have never ever used getElementsByXXX, so this is not an
important functionnality for me. OTOH, being able to load and manipulate
in memory a 10MB XML document is something I'd like to do which is
awkward with current DOM implementation I'm aware of.
