How about simplifying your code. Watch for word-wrap.

<html xmlns="http://www.w3.org/1999/xhtml";>

<title>doGetUrl.htm</title>
<script type="text/javascript">
function createRequestObject() {
var ret = null;
if (window.ActiveXObject) {
try {
ret = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {}
} else if(window.XMLHttpRequest) {
try {
ret = new XMLHttpRequest();
} catch(e) {}
}
return ret;
}
function doGetUrl(id,url) {
var http = createRequestObject();
http.open('get', url, false);
http.send(null);
var response = http.responseText;
if (response.indexOf('|' != -1)) {
var update = response.split('|');
var data = update[0];
document.getElementById(id).innerHTML = data;
}
}
</script>
</head>
<body>
<div id="myTest">myTest</div>
<br><br>
<a href="#" id="myHref" onMouseOver="doGetUrl('myTest','myfile')">change
content</a>
</body>
</html>


And you don't need
id="myHref"
as it's not referenced.

I haven't validated (per w3c) your code; I just made it work.

However, it would be noce to have a sample of what is returned;
apparently it must be a string with "|" in it...
