element:
Example
xmlDoc = loadXMLDoc("books.xml");
x = xmlDoc.getElementsByTagName('book');
var newel, newtext;
for (i = 0; i < x.length; i++) {
newel = xmlDoc.createElementNS("p", "edition");
newtext = xmlDoc.createTextNode("First");
newel.appendChild(newtext);
x[i].appendChild(newel);
}
// Output all titles and editions
y = xmlDoc.getElementsByTagName("title");
z = xmlDoc.getElementsByTagNameNS("p", "edition");
for (i = 0; i < y.length; i++) {
document.write(y[i].childNodes[0].nodeValue);
document.write(" - ");
document.write(z[i].childNodes[0].nodeValue);
document.write(" edition.");
document.write(" Namespace: ");
document.write(z[i].namespaceURI);
document.write("<br>");
