Quyidagi kod fragmenti "books_cdata.xml" faylini xmlDoc’ga yuklaydi va birinchi CDATA elementidan "Stun" stringini oladi:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
myFunction(this);
}
};
xhttp.open("GET", "books_cdata.xml", true);
xhttp.send();
function myFunction(xml) {
var xmlDoc = xml.responseXML;
var x = xmlDoc.getElementsByTagName("html")[0].childNodes[0];
var y = x.substringData(3, 4);
document.getElementById("demo").innerHTML =
x.nodeValue + "<br>" + y;
}
