SAX doesn't use the Java version of the event/listener stuff because
an XML document will generate several thousand events in a second or
two, and you'd really, really start to notice the overhead (unlike a
GUI, where you'll see at most a couple of dozen events in a second,
and usually much less).  It's very easy to implement the Java event
stuff on top of SAX if you want it, but there wasn't a good reason to
impose it on everyone.

All the best,
