This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
The book Processing XML with Java by Elliotte Rusty Harold is a good intro book, covering the various aspects of XML. There is a free online version available to read. There some good samples in it on how to do exactly what you are asking. After reading it, you can then look at other books that get in more details about the various topics (SAX, DOM, XSLT, etc).
