Processing XML with Java?

Elliotte Rusty Harold is an internationally respected writer, programmer, and educator. He is an Adjunct Professor of Computer Science at Polytechnic University in Brooklyn, where he lectures on Java and object-oriented programming. His Cafe con Leche Web site has become one of the most popular sites for information on XML. In addition, he is the author and coauthor of numerous books, the most recent of which are The XML Bible (John Wiley & Sons, 2001) and XML in a Nutshell (O'Reilly, 2002). 0201771861AB06062003
