       myFunction(this);
   }
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
    var x, i, attnode, old_att, xmlDoc, txt;
    xmlDoc = xml.responseXML;
    txt = "";
    x = xmlDoc.getElementsByTagName('book');
    for (i = 0; i < x.length; i++) {
        while (x[i].attributes.length > 0) {
            attnode = x[i].attributes[0];
            old_att = x[i].removeAttributeNode(attnode);
            txt += "Removed: " + old_att.nodeName + "}}"
