XML DOM data Property
Comment Object
Example
The following code fragment loads "books_comment.xml" into xmlDoc and outputs comment text from the first <book> 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++) {
if (x[i].nodeType == 8) {
txt += x[i].data + "<br>";
}
}
document.getElementById("demo").innerHTML = txt;
}
The output of the code above will be:
