Method Details

transform

public static void transform(InputStream styleSheet,
 InputStream xml,
 Writer out)
                      throws TransformerConfigurationException,
TransformerException

Transform input xml given a stylesheet.

Parameters:

styleSheet - the style-sheet

xml - input xml data

out - output

Throws:

TransformerConfigurationException - synopsis signals a problem creating a transformer object.

TransformerException - this is used for throwing processor exceptions before the processing has started.

newSecureDocumentBuilderFactory

public static DocumentBuilderFactory newSecureDocumentBuilderFactory()
                                                              throws ParserConfigurationException

This method should be used if you need a DocumentBuilderFactory. Use this method instead of DocumentBuilderFactory.newInstance(). The factory that is returned has secure configuration enabled.

Returns:

a DocumentBuilderFactory with secure configuration enabled

Throws:

ParserConfigurationException - if the JAXP parser does not support the secure configuration

newSecureSAXParserFactory

public static SAXParserFactory newSecureSAXParserFactory()
                                                  throws SAXException,
ParserConfigurationException

This method should be used if you need a SAXParserFactory. Use this method instead of SAXParserFactory.newInstance(). The factory that is returned has secure configuration enabled.

Returns:

a SAXParserFactory with secure configuration enabled

Throws:

ParserConfigurationException - if the JAXP parser does not support the secure configuration

SAXException - if there are another issues when creating the factory
