instance
In all examples, we will use the XML file books.xml, and JavaScript function loadXMLDoc().
The following code snippet can clone the first <book> node, then add it to the end of the node list:
xmlDoc=loadXMLDoc("books.xml");
var x=xmlDoc.getElementsByTagName('book')[0];
var cloneNode=x.cloneNode(true);
xmlDoc.documentElement.appendChild(cloneNode);
//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 />");
}
