This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
If you have this XML document in a string, and if you know that you'll always want to retrieve That specific part, and if you're certain that the structure won't change substantially, then some string operations (using indexOf and substring) should do the trick.
If you want to use SAAJ read and process the XML, then I have some examples in section 5.7 of my SCDJWS 5 Study Notes.
You can download the document in the SCDJWS Links section here or at http://www.javaforum.se/jforum/posts/list/549.page Best wishes!
