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);

Result:

Everyday Italian
Harry Potter
XQuery Kick Start
Learning XML
Everyday Italian

Example explained:

  1. Suppose "books.xml" is loaded into xmlDoc
  2. Get the node to copy (oldNode)
  3. Clone the node into "newNode"
  4. Append the new node to the the root node of the XML document
