XML DOM data Property


Comment Object Reference Comment Object

Example

The following code fragment loads "books_comment.xml" into xmlDoc and outputs comment text from the first <book> element:

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (xhttp.readyState == 4 && xhttp.status == 200) {
        myFunction(xhttp);
    }
};
xhttp.open("GET", "books_comment.xml", true);
xhttp.send();

function myFunction(xml) {
    var x, i, xmlDoc, txt;
    xmlDoc = xml.responseXML;
    txt = "";
    x = xmlDoc.getElementsByTagName("book")[0].childNodes;
    for (i = 0; i < x.length; i++) {
        if (x[i].nodeType == 8) {
            txt += x[i].data + "<br>";
        }
    }
    document.getElementById("demo").innerHTML = txt;
}
