Method Detail

transform

public static void transform(java.io.InputStream styleSheet,
                             java.io.InputStream xml,
                             java.io.Writer out)
                      throws javax.xml.transform.TransformerConfigurationException,
                             javax.xml.transform.TransformerException

Transform input xml given a stylesheet.

Parameters:

styleSheet - the style-sheet

xml - input xml data

out - output

Throws:

javax.xml.transform.TransformerConfigurationException - synopsis signals a problem creating a transformer object.

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

newSecureDocumentBuilderFactory

public static javax.xml.parsers.DocumentBuilderFactory newSecureDocumentBuilderFactory()
                                                                                throws javax.xml.parsers.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:

javax.xml.parsers.ParserConfigurationException - if the JAXP parser does not support the secure configuration

newSecureSAXParserFactory

public static javax.xml.parsers.SAXParserFactory newSecureSAXParserFactory()
                                                                    throws org.xml.sax.SAXException,
                                                                           javax.xml.parsers.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:

javax.xml.parsers.ParserConfigurationException - if the JAXP parser does not support the secure configuration

org.xml.sax.SAXException - if there are another issues when creating the factory

newSecureTransformerFactory

public static javax.xml.transform.TransformerFactory newSecureTransformerFactory()
                                                                          throws javax.xml.transform.TransformerConfigurationException

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

Returns:

a TransformerFactory with secure configuration enabled

Throws:

javax.xml.transform.TransformerConfigurationException - if the JAXP transformer does not support the secure configuration

newSecureSAXTransformerFactory

public static javax.xml.transform.sax.SAXTransformerFactory newSecureSAXTransformerFactory()
                                                                                    throws javax.xml.transform.TransformerConfigurationException

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

Returns:

a SAXTransformerFactory with secure configuration enabled

Throws:

javax.xml.transform.TransformerConfigurationException - if the JAXP transformer does not support the secure configuration
