So what is the difference? When to > use what? A couple of very incomplete thoughts: * Digester is one way (XML->Java), JAXB is two way (XML->Java and Java->XML). * Digester is nice for pulling just a few things out of an XML document, JAXB typically wants you to process the whole thing. * Digester rules can be calculated and constructed on the fly as you configure the Digester, and include some interesting matching rules that mean you don't always need to understand the entire document structure. JAXB is more like DOM, giving you a tree structure to process. * Digester lets you deal with dynamic sets of attributes gracefully (i.e. the SetPropertiesRule, for example); JAXB wants you to know them ahead of time. As with most things, it's kind of hard to say that one approach is always going to be better or worse; thinking through both approaches for each use case is probably the best approach -- in particular, I'd implement a couple of simple use cases both ways to see which one appeals to you more. > Thanks, > Kris Craig --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
