Brett,
Sorry for the delay, some of us are on vacation here...
1. The Xerces SAX parser can do both DTD validation and Schema validation,
although right now the Schema validation is not in sync with the latest W3C
Working Draft.
2. The following code fragment does what you want.
try {
Parser parser =
ParserFactory.makeParser("org.apache.xerces.parsers.SAXParser");
((Configurable)parser).setFeature("http://xml.org/sax/features/validation";,
true);
// you need to supply an error handler in order to see an error message!
parser.setErrorHandler(h);
parser.parse(args[0]);
} catch (Exception e) {
e.printStackTrace();
}
