XML DOM Clone Nodes

Examples

In the examples below, we will use the XML file books.xml, and the JavaScript function loadXMLDoc().

Copy a node and add it to the node list
This example uses cloneNode() to copy a node and append it to a node list.

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:

Everyday Italian
Harry Potter
XQuery Kick Start
Learning XML
Everyday Italian
