The xml-stylesheet processing instruction

public abstract Source getAssociatedStylesheet(Source xmlDocument, String media, String title, String charset) throws TransformerConfigurationException;

• This method reads the XML document indicated by the first argument, and looks in its prolog for the stylesheet that matches the criteria given in the other three arguments.

• If any of these are null, it ignores that criterion.

• Loads the stylesheet matching the criteria into a JAXP Source object and returns it.

• Use the TransformerFactory.newTransformer() object to convert this Source into a Transformer object.

• Throws a TransformerConfigurationException if there is no xml-stylesheet processing instruction pointing to an XSLT stylesheet matching the specified criteria.

// The InputStream in contains the XML document to be transformed
try {
  Source inputDocument = new StreamSource(in);
  TransformerFactory xformFactory = TransformerFactory.newInstance();
  Source xsl = xformFactory.getAssociatedStyleSheet(inputDocument, "print", null, null);
  Transformer stylesheet = xformFactory.newTransformer(xsl);

  Result outputDocument = new StreamResult(out);
  stylesheet.transform(inputDocument, outputDocument);
