Misol
Quyidagi kod fragmenti "books.xml" faylini yuklaydi, birinchi <book> tugunini klonlaydi va uni tugunlar ro‘yxati oxiriga qo‘shadi:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
myFunction(this);
}
};
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;
}
Yuqoridagi kodning natijasi quyidagicha bo‘ladi:
