Using AJAX to read XML

arguably not the wisest of all implementations of an AJAX, i have prepared a page on my personal website ( to put my CV online – at least a basic version.

i finished with the code, but still have to fill in the rest of the xml file to complete this task. this will change the content of a div on hovering over another div…

finally, this here is code only, apologies. ask questions if you have to.

here is a copy of the solution:

xml part:

<?xml version=”1.0″ encoding=”UTF-8″?>
    <lvl2 id=”aaa”>
        <lv3a attrib=”test_attribute”>node_text</lv3a>
            Some data not parsed

and the html & javascript:

function getXML(url) {
var xmlhttp;
var txt = “”;
var x,xx,i;
if (window.XMLHttpRequest) {
xmlhttp=new XMLHttpRequest();
else {
 xmlhttp=new ActiveXObject(“Microsoft.XMLHTTP”);
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState==4 && xmlhttp.status==200) {
x = xmlhttp.responseXML.documentElement.getElementsByTagName(“lvl2”);
for (i=0;i<x.length;i++) {
txt = txt + “<br />Attribute lvl2 : ” + x[i].getAttribute(‘id’);
xx = x[i].getElementsByTagName(‘lv3a’);
txt = txt + “<br />Node value lvl3a : ” +  xx[0].firstChild.nodeValue;
txt = txt + “<br />Attribute lvl3a : ” +  xx[0].getAttribute(‘attrib’);
xx = x[i].getElementsByTagName(‘lvl3b’);
txt = txt + “<br />Node value lvl3b : ” +  xx[0].firstChild.nodeValue;

<div id=”content” class=”text”>
<h4><a href=”#” onmouseover=”getXML(‘’)” onclick=”return false;”>Hover here!</a></h4>
