Receive notification of a warning.
SAX parsers will use this method to report conditions that are not errors or fatal errors as defined by the XML recommendation. The default behaviour is to take no action.
The SAX parser must continue to provide normal parsing events after invoking this method: it should still be possible for the application to process the document through to the end.
Filters may use this method to report other, non-XML warnings as well.
@param exception The warning information encapsulated in aSAX parse exception.
@exception org.xml.sax.SAXException Any SAX exception, possiblywrapping another exception.
@see org.xml.sax.SAXParseException
