Difference between Dom parser and Xerces Parser

Question

Hey, can anyone please tell me, what are difference between "Dom parser" and "Xerces Parser". What are the advantage and Disadvantages of either.

Answer 1

Xerces is a DOM parser. It's the Apache implementation in Java or C++.

The two you want to think about are SAX and DOM. DOM creates an object tree in memory; SAX does not. You can manipulate the object tree after the DOM is done parsing; SAX uses an event model to process XML on the fly.

Either SAX or DOM will "work". Your choice is usually based on whether or not you'll keep it in memory to manipulate it or process it in place. If the XML stream is gigabytes, you might not be able to store it all at once. In that case, SAX is a good choice because you can work with it on the fly as you parse.

Google is your friend: Fire it up to learn about DOM4J and JDOM.

I'd recommend JDOM if you're writing Java. It takes care of a lot of the boilerplate stuff.
