XML DOM isSameNode() Method
❮ Node Object
Example
The following code fragment loads "books.xml" into xmlDoc and tests whether the two nodes are the same node:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
   if (this.readyState == 4 && this.status == 200) {
       myFunction(this);
   }
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
    var xmlDoc = xml.responseXML;
    var x = 
xmlDoc.getElementsByTagName('book')[1];
    var y = 
xmlDoc.getElementsByTagName('book')[1];
    
document.getElementById("demo").innerHTML =
    
x.isSameNode(y);
