The following code fragment loads "books_cdata.xml" into xmlDoc and inserts data into the CDATA node of the first <html> element:

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];
    x.insertData(3, "Wonderful and ");
    document.getElementById("demo").innerHTML =
