okay. I think your first approach
from cElementTree import iterparse
for event, elem in iterparse("data.xml"):
if elem.tag == "schnappi":
count += 1
elem.clear()
is the right one for this case. with this code, the clear call will
destroy each schnappi record when you're done with it, so you
will release all memory allocated for the schnappi elements.
however, you will end up with a single toplevel element that
contains a large number of empty subelements. this is usually
no problem (it'll use a couple of megabytes), but you can get
rid of the dead schnappis too, if you want to. see the example
that starts with "context = iterparse" on this page
http://effbot.org/zone/element-iterparse.htm
for more information.
