XML DOM Clone Nodes
Try it Yourself - Examples
The examples below use the XML file books.xml.
A function, loadXMLDoc(), in an external JavaScript is used to load the XML file.
Copy a node and append it to an existing node
This example uses cloneNode() to copy a node and append it to the root node of the XML document
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);
//Output all titles
y=xmlDoc.getElementsByTagName("title");
for (i=0;i<y.length;i++)
{
document.write(y[i].childNodes[0].nodeValue);
document.write("<br />");
}
Output:
