Example

Note:Except for Internet Explorer, all major browsers treat whitespace or new lines as text nodes. Therefore, in the following example, we use a function to check the node type and only display element nodes. This ensures that the results are the same across all browsers.

For more information on differences between browsers, please read our DOM Browser chapter.

The following code loads "books.xml" into xmlDoc and loops through all child elements of the <bookstore> element:

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, i, xmlDoc, txt;
    xmlDoc = xml.responseXML;
    txt = "";
    x = xmlDoc.documentElement.childNodes;
    for (i = 0; i < x.length; i++) {
        if (x.item(i).nodeType == 1) {
            txt += x.item(i).nodeName + "<br>";
        }
    }
    document.getElementById("demo").innerHTML = txt;
}
