RE: Digester parsing user question

[Scott Sanders <ss...@nextance.com>]

As far as I know the code, all SAXExceptions are bubbled straight to the
user (you), Digester 'swallows' nothing.

Typically with a SAX parser, you get the first exception and then it
fails.  It is not like a compiler, which keeps reporting errors, so you
should be able to catch the first and only exception that the parser
spits out.

Cheers,
Scott Sanders

Re: Digester parsing user question

[Richard Frazer <ri...@haht.com>]

The digester implements ErrorHandler and is the default error handler 
for the SAX Parser.  The way it handles the "error" method is to just 
print out a message and continue along.  If you want to be able to do 
your own thing, you must implement the ErrorHandler interface yourself 
and call digester.setErrorHandler().

Ex.

        digester = new Digester();
        digester.setErrorHandler( new LittleErrorHandler() );

Where LittleErrorHandler is defined like this:


    private class LittleErrorHandler implements ErrorHandler
    {
        public void warning(SAXParseException e)
            throws SAXException
        {
            return;
        }

        public void error(SAXParseException e)
            throws SAXException
        {
            throw e;
        }

        public void fatalError(SAXParseException e)
            throws SAXException
        {
            throw e;
        }
    }
