public class BasicRegistryClient
extends AbstractRegistryClient<BasicResource>

RegistryClient concrete subclass which turns registry queries into BasicResource elements.

This class is implemented using an ad-hoc XPath-like mechanism for accumulating items of interest from the SAX stream, while ignoring anything else. It works well, and is fast. However there are certainly other, probably more flexible and better, ways of doing similar things. Probably there are libraries that can help with this sort of thing.
