xhttp.send();
function myFunction(xml) {
var x, y, cloneNode, i, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName('book')[0];
cloneNode = x.cloneNode(true);
xmlDoc.documentElement.appendChild(cloneNode);
// Output all title
y = xmlDoc.getElementsByTagName("title");
for (i = 0; i < y.length; i++) {
txt += y[i].childNodes[0].nodeValue + "<br>";
{}
document.getElementById("demo").innerHTML = txt;
{}
