Hi, Mukul
Thanks for your response, but I'm not looking for column and row numbers in the
XML document. I might have been a little ambiguous in using the word
"location". What I need is the reference to the Node object in the DOM
tree that caused the validation error. The perfect solution would be for the
SAXException to contain a reference to that Node.
I started looking at the source
of org.apache.xerces.impl.xs.XMLSchemaValidator, and I see a method called
processOneAttribute, which has all this info for attributes. There is also
code that deals with Elements and also has the references to Nodes. I'm going
to study this a little and see if I can do something with it.

You can set an error handler to a validator.
for e.g.,
Validator validator = schema.newValidator();
MyErrorHandler errorHandler = new MyErrorHandler();
validator.setErrorHandler(errorHandler);
validator.validate(new DOMSource ...
Then in MyErrorHandler, you should write as,
class MyErrorHandler implements ErrorHandler {
public void fatalError(SAXParseException e) throws SAXException {
}
public void error(SAXParseException e) throws SAXException {
}
public void warning(SAXParseException e) throws SAXException {
}
within the methods, fatalError, error or warning, you can get location
of the error/problem as,
e.getLineNumber()
e.getColumnNumber()
