Handling Element Nodes:

   case Node.ELEMENT_NODE: {
      System.out.println("Element : " + node.getNodeName());

      NodeList childNodes = node.getChildNodes();	
      if(childNodes != null) {
         int length = childNodes.getLength();
         for (int loopIndex = 0; loopIndex < length ; loopIndex++)
         {
            display_names(childNodes.item(loopIndex));
         }
      }
      break;
   }
