PFB the code snippet
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
setInterval(loadFile,2000);

function loadFile()
{
var data = "";

xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
var myval =function(xmlhttp.responseText,"MYVAL");
if(myval <0){
document.getElementById("rtHeader_val").src="images/LTE/1.png";
}
document.getElementById("myval_1").innerHTML=myFunction(xmlhttp.responseText,"MYVAL");

if(xmlhttp)
{
//myinfo is input file from which application reads the values
xmlhttp.open("GET","/config/myinfo",false);
xmlhttp.send();
data=xmlhttp.responseText;
}

}
This code updates value after 2 secs on chrome but not IE 8

In javascript I have set an interval of 5secs. every 5 secs script executes and reads the file using XmlHttpRequest object and parsing the xml response. this code works well in google chrome but in IE 8.0 I need to launch a browser again to see the changed values in file. This file is get updated by other process.

Please see the comment above. It meant to say: you need to provide a relevant code sample. At this moment, I cannot see a reason why IE8 did not work for you.
After 60 questions in this forum, I think you should get a feeling what's needed to get successful advice.
By also, it looks like you rather should review your design.

Instead of setInterval it would be better if you had simulated it by setTimeout
