XML DOM - isEqualNode Method

Hello folks! welcome back to a new edition of our tutorial on XML DOM. In this tutorial, we are going to be studying about the XML DOM isEqualNode Method.

The isEqualNode method tests whether two nodes are equal.

Two nodes are equal when their names are the same, their attributes have same name and value (does not have to be in the same order), and their child nodes are equal and in the same order.


The following below is the syntax to use the isEqualNode Method -

nodeObject.isEqualNode(Node arg)

Parameter Details

S.No.Parameter & Description


It is the node with which equality condition is evaluated. It is of type Node.

Return Value

This method returns the boolean value true if the nodes are equal otherwise false.


Following below are the node.xml contents -

<?xml version = "1.0"?>
   <Employee category = "Technical">
   <Employee category = "Non-Technical">
   <Employee category = "Management">

The following example illustrates the usage of the isEqualNode method -

<!DOCTYPE html>
         function loadXMLDoc(filename) {
            if (window.XMLHttpRequest) {
               xhttp = new XMLHttpRequest();
            } else // code for IE5 and IE6 {
               xhttp = new ActiveXObject("Microsoft.XMLHTTP");
            return xhttp.responseXML;
         xmlDoc = loadXMLDoc("/dom/node.xml");

         e1 = xmlDoc.getElementsByTagName("Employee")[1];
         e2 = xmlDoc.getElementsByTagName("Employee")[2];
         document.write("Checks the equality result : ")


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

Checks the equality result : false

Alright guys! This is where we are going to be rounding up for this tutorial post. In our next tutorial, we will be studying about XML DOM lookupNamespaceURI Method.
