DOMParser and Validation

[Brett McLaughlin <br...@earthlink.net>]

I posted this yesterday, and never heard anything.  I hate to be a nag,
but this is a major issue.  Help, anyone?

I must be really missing the boat here.  If I have this code:

try {
    DOMParser parser = new DOMParser();
    parser.setFeature("http://xml.org/sax/features/validation", true);
    parser.parse(new InputSource(in));
    Document doc = parser.getDocument();
} catch (Exception e) {
    e.printStackTrace();
}

and invoke it where in is a FileInputStream wrapping a local XML
document, which specifies a DTD that makes the document invalid, I get
absolutely no exceptions.  I can parse the same document with a SAX
Parser with validation on (and a registered ErrorHandler that gripes on
the error() callback), I get errors.  So why isn't validation for the
DOMParser letting me know something is invalid?

Thanks,
Brett

I think you first have to set the errorhandler with 

setErrorHandler() for the DOMParser.

Does it work ?

Did you call setErrorHandler() for the DOMParser?

I think the problem is you didn't register an ErrorHandler with the DOM
Parser.  It needs one just like the SAX Parser does.
