XML DOM item() Method
NodeList Object
Example
Note: All major browsers, except Internet Explorer, treat empty white-spaces or new lines as text nodes. So, in the example below, there is a function that checks on node type, and displays only Element nodes. This way, the result will be equal in all browsers. To read more about the differences between browsers, please read our DOM Browsers chapter.
The following code fragment loads "books.xml" into xmlDoc and loops through all child element nodes of the <bookstore> 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 x, i, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.documentElement.childNodes;
for (i = 0; i <
x.length; i++) {
if (x.item(i).nodeType
== 1) {
txt += x.item(i).nodeName + "<br>";
}
}
document.getElementById("demo").innerHTML
= txt;
}
Output:
book
book
book
book
