������� myFunction(xhttp);
��� }
};
xhttp.open("GET", "books.xml", true);
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 titles
y = xmlDoc.getElementsByTagName("title");
for (i = 0; i < y.length; i++) {
txt += y[i].childNodes[0].nodeValue + "<br>";
}
document.getElementById("demo").innerHTML = txt;
