... etc. Ithink that in digester it would be a good idea to change the
JSP-ish matching rules to XPATH expressions. At the same time digester
could use JDOM or DOM4J (they have esstially the same XPATH engine).
XPATH was designed to walk through an XML graph, so you can express
as complex or as simple rules as you want. both JDOM and DOM4j gives
you a pretty convenient (I mean collections) interface to the
document. Comments?
