XML DOM substringData() Method

Example

The following code fragment loads "books_cdata.xml" into xmlDoc and gets the "Stun" string form the first CDATA element:

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (xhttp.readyState == 4 && xhttp.status == 200) {
        myFunction(xhttp);
    }
};
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;
}

Output:

Stunning!
