XML DOM appendData() Method
Comment Object
Example
The following code fragment loads "books_comment.xml" into xmlDoc and appends text to the first comment element:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
��� if (xhttp.readyState == 4 && xhttp.status == 200) {
������� myFunction(xhttp);
��� }
};
xhttp.open("GET",
"books_comment.xml", true);
xhttp.send();
function myFunction(xml) {
var x, i,
xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName("book")[0].childNodes;
for (i = 0; i < x.length; i++) {
// Process only
comment nodes
if (x[i].nodeType
== 8) {
x[i].appendData(" Special Offer");
txt += x[i].data + "<br>";
}
}
document.getElementById("demo").innerHTML = txt;
}
Output:
125 Simple and Delicious Recipes (Hardcover) Special Offer
