XML DOM cdata length Property

❮ CDATA Object

Example

The following code fragment loads "books_cdata.xml" into xmlDoc and gets the text node data and length from the first <title> element:

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

function myFunction(xml) {
    var xmlDoc = xml.responseXML;
    var x = xmlDoc.getElementsByTagName("html")[0].childNodes[0];
    document.getElementById("demo").innerHTML =
    x.data + " - Length: " + x.length;
}

The output of the code above will be:

Stunning! - Length: 16
Try it Yourself »

Remember that the length above is from the entire CDATA section (<b>Stunning!</b>), not just the text.

Definition and Usage

The length property returns the number of characters in the selected node
