❮ Element Object

Example

The following code fragment loads "books.xml", clones the first <book> node and then adds it to the end of the node list:

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;
}

The output of the code above will be:
