Following example demonstrates the usage of the isEqualNode 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");

         e1 = xmlDoc.getElementsByTagName("Employee")[1];
         e2 = xmlDoc.getElementsByTagName("Employee")[2];
         document.write("Checks the equality result : ")
         document.write(e1.isEqualNode(e2));
      </script>
   </body>
</html>

Execution

Save this file as nodemethod_isequalnode.htm on the server path (this file and node.xml should be on the same path in your server). We will get the output as shown below −

Checks the equality result : false
dom_node_object.htm
