      <ContactNo>1234562350</ContactNo>
      <Email>stephaniefrancis@xyz.com</Email>
   </Employee>
</Company>


The following example illustrates the usage of the Element Object removeAttributeNode 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');
         for (i = 0;i < x.length;i++) {
            while (x[i].attributes.length > 0) {
               y = x[i].attributes[0];
               z = x[i].removeAttributeNode(y);

               document.write("Removed : " + z.nodeName)
               document.write(": " + z.nodeValue)
               document.write("<br>")
            }
          }
      </script>
   </body>
</html>

Output

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

Removed : category: technical
Removed : category: non-technical
Removed : category: Management
