Some warnings are generated only by the validating parser.The non-validating parser's main goal is to operate as rapidly as possible, but it too generates some warnings.(Descriptions of these options, to configure the factory to return a namespace-aware parser.Sun's implementation supports any combination of configuration options.

The best way to demonstrate the different types of validation is to modify the code of the XML file being parsed, as well as the associated schema and DTDs, to break the processing and get the application to generate exceptions.Remember that your application will not generate a validation exception unless you supply an error handler such as the one here.As mentioned earlier, warnings are generated only when the SAX parser is processing a DTD.option and providing the name of the schema source file to be used.It is important to recognize that the only reason an exception is thrown when a file fails validation is as a result of the error-handling code shown in Setting up Error Handling. public void warning(SAXParse Exception spe) throws SAXException public void error(SAXParse Exception spe) throws SAXException public void fatal Error(SAXParse Exception spe) throws SAXException // ...
