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 (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};
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;
}
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};
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
