   </Employee>
</Company>


The example below illustrates the usage of Element Object getAttributeNode method -

<!DOCTYPE html>
   <head>
      <script>
         function loadXMLDoc(filename) {
            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("/dom/node.xml");

         x = xmlDoc.getElementsByTagName('Employee');
         document.write("Display all the attribute nodes ");
         document.write("<br>");
         for(i = 0;i < x.length;i++) {
            y = x.item(i).getAttributeNode("category");
            document.write(y.name);
            document.write(" = ");
            document.write(y.value);
            document.write("<br>");
         }
      </script>
   </body>
</html>

Output

Save this file as elementmethod_getattributenode.html on the server's path (this file and the node.xml should be on the same path in your server). This is going to give us the following output below -

Display all the attribute nodes
category = technical
category = non-technical
category = Management
