Okay, I have now read up on iterators and generator - WOW! that's so
cool!.. I immediately rewrote the search part of my program that had
been giving me problems - with generators it just works perfectly and
the code is so much simpler!

I have implemented Uche's generators now and the function that loads an
XML file into my programs internal format has now gone from 6-7 seconds
load time to 1-2 second for the 219Kb XML file I am using for testing on
my Athlon XP 1800+.

Now - my program also saves it's data to disk by creating a dom and
filling it with the right nodes and then writing it to disk with
PrettyPrint (which takes over 20 seconds on my machine with the 219Kb
file). I am sure this can be done much faster with 4Suite somehow,
but how?

right now I use xml.dom.implementation to create the empty dom, I am
betting it is possible to do the same using domlette, I just can't grok
how without a little helping hand :)

Also it would be great if there was a way to ditch PrettyPrint as I
would then be completely rid of PyXML, which seems to be giving py2exe
some problems.

Once again, thanks for the help so far, you guys are great! :)
