Printing a Node

Question

Hello everyone:
I am parsing an XML instance using xerces/w3cDOM, how do I print out a Node? I've looked around the API and only found a way of printing the whole document using getDocumentOwner and serializing it
tempNode is a Node
OutputFormat format = new OutputFormat( tempNode.getOwnerDocument(), "UTF-8", true ); /** Serialize DOM **/
StringWriter stringOut = new StringWriter(); /** Writer will be a String **/
XMLSerializer serial = new XMLSerializer( stringOut, format );
try {
serial.asDOMSerializer(); /** As a DOM Serializer **/
serial.serialize( (tempNode.getOwnerDocument()).getDocumentElement());
} catch (Exception exc){}
System.out.println("Tree is:\n"+stringOut.toString());
The above code prints out the whole document. How do I print tempNode?
Thanks

You can use a transformer.
first import javax.xml.transform, set up an output stream (outStream) then:
    Transformer trans;
    TransformerFactory = transfac = TransformerFactory.newInstance();
    try{
      trans = transfac.newTransformer();
    catch(TransformerConfigurationException t){
      //do something
    catch(IllegalArgumentException i){
      //do something
    try{
      trans.transform(new DOMSource(tempNode), new StreamResult(outStream));
    catch(TransformerException t){
      //do something
    }If you want to print the Node to the screen just use System.out as your output stream. You can also store the text input in an array if you use a ByteArrayOutputStream.
