XML DOM textContent Property
Element Object
Example
The following code fragment loads "books.xml" into xmlDoc and gets text nodes 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.xml", true);
xhttp.send();
function myFunction(xml) {
var xmlDoc = xml.responseXML;
var x =
xmlDoc.getElementsByTagName("title")[0];
document.getElementById("demo").innerHTML =
"Text
Nodes: " + x.textContent;
}
The output of the code above will be:

Definition and Usage
The textContent property returns or sets the text from the selected element.
On returning text, this property returns the value of all text nodes within the element node.
On setting text, this property removes all child nodes and replaces them with a single text node.
Note: This property does not work in Internet Explorer 9 (it returns undefined).
Syntax
Return text:
elementNode.textContent
Set text:
elementNode.textContent=string
Tips and Notes
Tip: For setting and returning the text value from a node you should use the text node nodeValue property.
Example 2
The following code fragment loads "books.xml" into xmlDoc and gets text nodes from the first <book> element, and replaces all nodes with a new text node:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
var xmlDoc = xml.responseXML;
var x =
xmlDoc.getElementsByTagName("book")[0];
document.getElementById("demo").innerHTML =
"Before: "
+ x.textContent + "<br>";
x.textContent = "hello";
document.getElementById("demo").innerHTML +=
"After: "
+ x.textContent;
}
The output of the code above will be:
Before: Everyday Italian Giada De Laurentiis 2005 30.00
