var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (xhttp.readyState == 4 && xhttp.status == 200) {
        myFunction(xhttp);
    }
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
    var x, y, z, i, newel, newtext, xmlDoc, txt;
    xmlDoc = xml.responseXML;
    txt = "";
    x = xmlDoc.getElementsByTagName("book");
    for (i = 0; i < x.length; i++) {
        newel = xmlDoc.createElement("edition");
        newtext = xmlDoc.createTextNode("first");
        newel.appendChild(newtext);
        x[i].appendChild(newel);
    }
    // Output all title and edition
    y = xmlDoc.getElementsByTagName("title");
    z = xmlDoc.getElementsByTagName("edition");
    for (i = 0; i < y.length; i++) {
        txt += y[i].childNodes[0].nodeValue +
        " - Edition: " +
        z[i].childNodes[0].nodeValue + "<br>";
