Copy a Node

The cloneNode() method creates a copy of a specified node.

The cloneNode() method has a parameter (true or false). This parameter indicates if the cloned node should include all attributes and child nodes of the original node.

The following code fragment copies the first <book> node and then adds the copy to the end of the node list:

xmlDoc=loadXMLDoc("books.xml"); var oldNode=xmlDoc.getElementsByTagName(‘book‘)[0]; var newNode=oldNode.cloneNode(true); xmlDoc.documentElement.appendChild(newNode); //Output all titles var y=xmlDoc.getElementsByTagName("title"); for (i=0;i<y.length;i++) { document.write(y[i].childNodes[0].nodeValue); document.write("<br />"); }

Output:
