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 appends it to the root node of the document:

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

Append the new node to the the root node of the XML document
