Say you're parsing something like this: ... <foo> <bar>xxx</bar> </foo> ... When your main handler sees the <foo> tag, create a new "FooHandler" object. Your main handler would then need to delegate all events to the FooHandler, until the corresponding </foo> is seen. Not that this is particularly easy to implement. In fact, I started to implement something similar (in Java), but got fed up ... I've reverted to using a DOM as input, for the time being. The main complication is that the delegating handler has to maintain a context-stack while it's delegating, in order to match the correct end-tag. One way around this might be to get the FooHandler to notify the main handler when it's finished. Just an idea ... -- Mike Williams xml-dev: A list for W3C XML Developers.
