XML DOM removeAttributeNode() Method

❮ Element Object

Example

The following code fragment loads "books.xml" into xmlDoc and removes the "category" attribute nodes from all <book> elements:

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, attnode, old_att, xmlDoc, txt;
    xmlDoc = xml.responseXML;
    txt = "";
    x = xmlDoc.getElementsByTagName('book');
    for (i = 0; i < x.length; i++) {
        while (x[i].attributes.length > 0) {
            attnode = x[i].attributes[0];
            old_att = x[i].removeAttributeNode(attnode);
            txt += "Removed: " + old_att.nodeName +
            ": " + old_att.nodeValue + "<br>";
        }
    }
document.getElementById("demo").innerHTML = txt;
}

Output:

Removed: category: cooking
Removed: category: children
Removed: category: web
Removed: category: web
Removed: cover: paperback
