XML DOM: Clone Nodes

Let's see how to clone an element node with cloneNode().

Clone a Node with cloneNode() Method

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.

Example: colone the first <book> node and appends it to the root node of the document:

oldNode = xmlDoc.getElementsByTagName('book')[0];  
newNode = oldNode.cloneNode(true);
