            if (window.XMLHttpRequest) {
               xhttp = new XMLHttpRequest();
            } else // code for IE5 and IE6 
            {
               xhttp = new ActiveXObject("Microsoft.XMLHTTP");
            }
            xhttp.open("GET",filename,false);
            xhttp.send();
            return xhttp.responseXML;
         }
      </script>
   </head>
   <body>
      <script>
         xmlDoc = loadXMLDoc("/node.xml");
         x = xmlDoc.createAttribute("City");
         x.nodeValue = "fourth";

         y = xmlDoc.getElementsByTagName("Email");
         y[0].setAttributeNode(x);
