I tried the 2nd solution, to throw an exception from the ErrorHandler methods, and it works.
It seems like what I am trying to do is a pretty basic thing - don't process the file if it is not valid. I was too zeroed in on finding a method like setAbortOnValidationError(true) somewhere within Xerces, that I overlooked the obvious solution of throwing an exception from ErrorHandler.

System.exit() terminates the whole JVM, so not "elegant enough for your tastes" is quite the understatement. ;^) I think the usual (intended?) thing is do as Richard's second suggestion--more specifically throw a SAXException from the ErrorHandler's error(), warning(), and fatalError() methods; XmlReader.parse() will pass on / re-throw that same SAXException.

I'm not Xerces expert, so there may be a simpler way, but... Couldnt you register your own custom error handler, and simply kill the thread after you log/report the error? IE: public class MySAXApp extends DefaultHandler { public MySAXApp (){ super();} public void startDocument (){} ...//other methods here public void error(SAXParseException e) { System.out.println("** " +e.getMessage() + " **"); System.out.println("LINE: " + e.getLineNumber()); System.out.println("PUBLIC_ID: " + e.getPublicId()); System.out.println("SYSTEM_ID: " + e.getSystemId()); System.exit(); } publiv static void main() { XMLReader xr = new SAXParser(); ...//turn on options here MySAXApp handler = new MySAXApp(); xr.setErrorHandler(handler); ...//parse here } If the call to system.exit() isn't elegant enough for your tastes, You may alternatively be able to throw an exception in the error() function and catch it outside the call to parse() (I haven't tried this though). -- Richard Rowell <[EMAIL PROTECTED]> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
