If your problem is with the memory consumption it doesn't really matter 
which parser you use, you'll end up with about the same document size in 
memory. Your best choice in this case is to find a more compact 
representation for your data. You can use a SAX parser to read the data 
and build your own structure from it, or use XML data binding (such as 
with Castor - http://www.castor.org; I have an article on IBM 
developerWorks that gives some examples for this at 
http://www-106.ibm.com/developerworks/xml/library/x-bindcastor/index.html) 
to automatically convert between XML and your data structures.

If you're really concerned with speed the parser choice can make a 
difference - Piccolo (http://piccolo.sourceforge.net/index.html) looks 
very good if you don't need validation.

5 files of 101KB doesn't sound like much in any case. Are you sure your 
problem is due to the XML document handling?
