That can usually be done in a couple of lines in Python. The approach I 
keep recommending is to use cElementTree (in the stdlib), potentially its 
iterparse() function if the file is too large to easily fit into memory, 
but the code won't change much either way.

You might want to skip through this list a bit, similar questions have been 
coming up every couple of weeks. The responses often include mostly 
complete implementations that you can borrow from.
