Printing XML with attributes

Question

Hi,
I wrote some code to generate DOM trees, and some more code to print a tree as a string.
But my the string loses attributes - i.e. all tags come out without attributes. And I am not sure why....
public static String getStringXml(Document xmlDoc)
          //Output the XML to string
          TransformerFactory fac = TransformerFactory.newInstance();
          Transformer transformer = null;
          StringWriter writer = new StringWriter();
          try
               transformer = fac.newTransformer();
               transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
               StreamResult result = new StreamResult(writer );
               DOMSource source = new DOMSource(xmlDoc);
               transformer.transform(source, result);
          catch (TransformerConfigurationException e)
               e.printStackTrace();
          catch (TransformerException e)
               e.printStackTrace();
          return writer.toString();
     }

Answer 1

It is possible I am doing something wrong when adding attriubtes:
Element myElement = xmlDoc.createElement("myElement");
myElement.setAttribute("id", "first");
