Changing the parser
It's easy to change out the parser that the JAXP factory classes use. Changing the parser actually means changing the parser factory, because all SAXParser and DocumentBuilder instances come from these factories. The factories determine which parser is loaded, so it's the factories that you must change. To change the implementation of the SAXParserFactory interface, set the Java system property javax.xml.parsers.SAXParserFactory. If this property isn't defined, then the default implementation (whatever parser your vendor specified) is returned. The same principle applies for the DocumentBuilderFactory implementation you use. In this case, the javax.xml.parsers.DocumentBuilderFactory system property is queried.
