> The current default error handling behavior is for the SAX parses to NOT throw exceptions when they occur, but instead to log them to stderr. This is fine and I am not suggesting that be changed. However, there is a wiki article (http://wiki.apache.org/commons/Digester/FAQ) that describes the common task of implementing an error handler that throws encountered errors.
> If this is so common, it would seem that including such an error handler in the API would be a very convenient thing to do.
> I propose that the following class be added to the digester to make it convenient for anyone to turn on this behavior:
> {code}package org.apache.commons.digester3;
> import org.xml.sax.ErrorHandler;
> import org.xml.sax.SAXException;
> import org.xml.sax.SAXParseException;
> public class DefaultThrowingErrorHandler implements ErrorHandler
> {
>     @Override
>     public void warning(SAXParseException e) throws SAXException
>     {
>         throw e;
>     }
>     @Override
>     public void error(SAXParseException e) throws SAXException
>     {
>         throw e;
>     }
>     @Override
>     public void fatalError(SAXParseException e) throws SAXException
>     {
>         throw e;
>     }
> }{code}
> Furthermore, I propose that the DigesterLoader and Digester classes have setThrowEncounteredSAXErrors(boolean) methods that set the error handler to the DefaultThrowingErrorHandler..
