      <ContactNo>1234567890</ContactNo>

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


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

<!DOCTYPE html>
<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("Before removing the attribute: ");
         document.write(x[1].getAttribute('category'));
         document.write("<br>");

         x[1].removeAttribute('category');

         document.write("After removing the attribute: ");
         document.write(x[1].getAttribute('category'));
      </script>
   </body>
</html>

Output

Save this file as elementmethod_removeattribute.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 -

Before removing the attribute: non-technical
After removing the attribute: null
