You need to add if condition before write it on document.

Try code like this

<script>
  if (window.XMLHttpRequest)
   {// code for IE7+, Firefox, Chrome, Opera, Safari
    xmlhttp=new XMLHttpRequest();
   }
  else
   {// code for IE6, IE5
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
   }
  xmlhttp.open("GET","Default.xml",false);
  xmlhttp.send();
  xmlDoc=xmlhttp.responseXML; 

 var management=xmlDoc.getElementsByTagName("Management");

document.write("<tr><td>");
if(management[i].getElementsByTagName("RepresentativeName")[0].childNodes[0]){
  document.write(management[i].getElementsByTagName("RepresentativeName")[0].childNodes[0].nodeValue);
}else{
  document.write('');
}
document.write("</td></tr>");

</script>

you mean to say i need to check whether it has a value or not if yes render the data else render ' '. Am i right ? – Krishna9960 Jul 14 '15 at 10:46
i have such a huge xml file. data can be there cannot be there...adding conditions everywhere is a right thing ? – Krishna9960 Jul 14 '15 at 10:47
You need to do so, otherwise it fails every time open with IE – Bhavin Solanki Jul 14 '15 at 11:14
Did it Bhavin Solanki. Thanks for the help buddy. Actually your logic met my objective but somewhere in my mind i am not satisfied idk why. anyways thanks a lot – Krishna9960 Jul 14 '15 at 12:00
