if (this.readyState == 4 && this.status == 200) {
myFunction(this);
}
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
var x, i, newComment, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName("book");
for (i = 0; i < x.length; i++) {
newComment = xmlDoc.createComment("Revised April 2008");
x[i].appendChild(newComment);
}
for (i = 0; i < x.length; i++) {
txt += x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue +
" - " +
x[i].lastChild.nodeValue + "<br>";
