There are 2 basic kinds of XML parsers; SAX-based and DOM-based.

DOM-based parsers create a tree in memory of the XML nodes. This can  
make it easier for your application to process the XML, but it will  
use a LOT more memory. A good DOM parser is Xerces.

SAX parsers work using an event-based system. As they encounter  
various XML elements, they will invoke call-backs for you. This can  
make your application harder to write, because you have to create a  
state machine in order to parse complicated XML documents. SAX  
parsers are faster than DOM parsers, and use a lot less memory  
(depending on how you structure your call-back functions of course).  
A very good SAX parser is Expat.
