XML DOM replaceData() Method

❮ Text Object

Example

The following code fragment loads "books.xml" into xmlDoc and replaces the first eight characters from the text node in the first <title> element with "Easy":

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("title")[0].childNodes[0];
    document.getElementById("demo").innerHTML =
    x.nodeValue;

    x.replaceData(0,8, "Easy");
    document.getElementById("demo").innerHTML +=
    "<br>" + x.nodeValue;
}

Output:
