Transform XML and display xsl:message

Question

Hi,
I have a simple method to transform XML. My XSLT has <xsl:message> to help debugging while transforming. How do I access the messages to System.out.printLn?
public static Document transformXML(Document xmlDoc, Document xslDoc) throws XMLHelperException {
          try {
               TransformerFactory factory = TransformerFactory.newInstance();
               Transformer transformer = factory.newTransformer(new DOMSource(xslDoc));
               DOMResult result = new DOMResult();
               transformer.transform(new DOMSource(xmlDoc), result);
               org.w3c.dom.Node resultNode = result.getNode();
               if (resultNode instanceof Document) return (Document)resultNode;
               else return result.getNode().getOwnerDocument();
          } catch (TransformerConfigurationException ex) {
               throw new XMLHelperException("Unable to perform transform " + ex.getLocationAsString(), ex);
          } catch (TransformerException ex) {
               throw new XMLHelperException("Unable to perform transform " + ex.getLocationAsString(), ex);
     }thanks for the help.

public class XForm {
     public static void main(String[] args) throws Exception {
          InputStream xslStream = null;
          InputStream xmlStream = null;
          try {
               TransformerFactory tf = TransformerFactory.newInstance();
               xslStream = new BufferedInputStream(new FileInputStream(args[1]));
               Transformer t = tf.newTransformer(new StreamSource(xslStream));
               tf.setErrorListener(new ErrorListener() {
                    public void error(TransformerException ex) throws TransformerException {
                         ex.printStackTrace();
                    public void fatalError(TransformerException ex) throws TransformerException {
                         ex.printStackTrace();
                    public void warning(TransformerException ex) throws TransformerException {
                         ex.printStackTrace();
               xmlStream = new BufferedInputStream(new FileInputStream(args[0]));
               t.transform(new StreamSource(xmlStream), new StreamResult(System.out));
          } catch (Exception e) {
               e.printStackTrace();
          } finally {
               if (xslStream != null)
                    xslStream.close();
               if (xmlStream != null)
                    xmlStream.close();
