The following code snippet copies the first <book> node and then adds this backup to the end of the node list:
xmlDoc=loadXMLDoc("books.xml");
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 />");
}
