Milind:
If I understand what the ErrorHandler is supposed to
do, it's going to have its warning, error, and fatal
error methods called when there's a problem. (The
argument to each one is SAXParseException.) I thought
that passing a document that was invalid against the
schema would trigger one of those three events.
I can certainly try your suggestion and have each of
these methods rethrow a SAXException.
But if you're asking why I need an ErrorHandler at
all, why I don't just have the parser signal the
failure by throwing an exception, I agree with you -
that's what I thought would happen. But it didn't, so
I was following a suggestion from this mailing list to
write an ErrorHandler.
You might be right. What else could I be doing to
obviate the need for an ErrorHandler? I've set the
features on the parser, as well as I understand them.
Perhaps I'm missing something else. - MOD
