I agree with you, W3C DOM APIs are painful to use. But don't you think
that by adding namespace in Configuration, and then selection by
namespace and then... , you will end up with a yet another java-friendly
equivalent to DOM when there are already JDOM and DOM4J ?
DOM4J's nice interface-based design can be mapped on about anything
(there are great examples in the distro), even on data structures where
you cannot travel up in the hierarchy like Configuration. So what about
a DOM4JConfigurable interface and two adapter classes to wrap a
Configuration as a DOM4J and a DOM4J as a Configuration to ensure
compatibility with existing code ?
Just my .02 euro...
