/**
* Create from factory a DocumentBuilder and let it create a org.w3c.dom.Document. This method

*
* @param input a parser input (for URL users use: <code>new InputSource(url.toExternalForm())
* </code>
* @param validate if true validating parser is used
* @param namespaceAware if true DOM is created by namespace aware parser
* @param errorHandler a error handler to notify about exception or <code>null</code>
* @param entityResolver SAX entity resolver or <code>null</code>; see class Javadoc for hints
* @throws IOException if an I/O problem during parsing occurs
* @throws SAXException is thrown if a parser error occurs
* @throws FactoryConfigurationError Application developers should never need to directly catch
* errors of this type.
* @return document representing given input, or null if a parsing error occurs
