Hey Mukul, Yup, you pointed me in the right direction -- thanks...but I still think there's a bug.
If you look at the docs to ErrorHandler: http://docs.oracle.com/javase/6/docs/api/org/xml/sax/ErrorHandler.html It says that: " it is up to the application to decide whether to throw an exception for different types of errors and warnings." In other words, the error handler gives an app the ability to decide whether or not to throw an exception when an error occurs. The issue that I was having was that I registered an error handler that threw an exception. I couldn't replicate it from the SourceValidator sample because it reports errors directly from the error handler and doesn't throw an exception there at all. The problem that I have is that in this case: <a xmlns="http://www.rackspace.com/xerces/test"; even="23"/> The SAXParseException propagated all the way up to my app as expected. In this case, however: <e xmlns="http://www.rackspace.com/xerces/test";> <even>23</even> </e> The exception never propagated up -- it got lost! I totally see that as a bug. I've reworked the code to not throw an exception in the ErrorHandler -- but I don't feel this is very efficient. I want to fail fast on the first parse error I see and not have to wait for the entire message to finish parsing. Thanks, -jOrGe W.
