XML DOM isSameNode() Method

If two nodes are the same, this method returns true, otherwise it returns false.

Example
In all examples, we will use the XML file books.xml, as well as the JavaScript function loadXMLDoc().
The following node checks whether two nodes are the same:
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName("book")[0];
y=xmlDoc.getElementsByTagName("book")[1];
document.write(x.isSameNode(y));
The output of the above code is:
false
