Actually the problem may be in this code

if(xmlHttp.status == 200)
{
var textout = xmlHttp.responseText;
try
{
var x= new DOMParser().parseFromString(textout, 'text/xml');
xmldom.async="false";
xmldom.loadXML(x);
alert(xmldom);
xmlObj=xmldom.documentElement;
var master = [document.getElementById('name'),document.getElementById('password'),
document.getElementById('realname'),document.getElementById('email'),
document.getElementById('title'),document.getElementById('desc')];
var length=xmlObj.childNodes.length;
for(var i=0;i<master.length;i++)
{
master[i].value = xmlObj.childNodes[i].firstChild.nodeValue;
}
}

I am getting the textout value as xml in IE but didnt get the values in Mozilla browser
