XML DOM removeAttribute() Method

❮ Element Object

Example

The following code fragment loads "books.xml" into xmlDoc and removes the "category" attribute 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 xmlDoc = xml.responseXML;
    var x = xmlDoc.getElementsByTagName("book");
    document.getElementById("demo").innerHTML =
    x[0].getAttribute('category') + "<br>";

    x[0].removeAttribute('category');
    document.getElementById("demo").innerHTML +=
    x[0].getAttribute('category');
}

Output:
