I am trying to capture a response from XML using AJAX into JavaScript. The XML is full functioning as I have tried a test script on a file on its own and it works fine. However when accessing the XML data using JavaScript DOM I always get NULL as tested using alert. I have verified that JavaScript can pick up the right node name, however not get the value, even if i try a simple "Hello".

Here is my XML in PHP:
---------------------------------------------------------------------
   echo"<?xml version='1.0' encoding=\"utf-8\"?>";
   echo "<data>";
   echo "<pause>" .$_SESSION['prog'].  "</pause>";
   echo "</data>";
 ---------------------------------------------------------------------
I have set the content type to XML at the top of the document.

My AJAX JavaScript Code:

---------------------------------------------------------------------
 function ajaxGetPHP()

            {

                if(http1.readyState == 4 && http1.status == 200) {

                    //document.getElementById("r").innerHTML = http1.responseText;

                    var xmlDoc = http1.responseXML.documentElement;
                    document.getElementById("r").innerHTML = xmlDoc.getElementsByTagName("pause")[0].nodeName;
                    load = xmlDoc.getElementsByTagName("pause")[0].nodeValue;
                    alert(load);

                } else {
                    document.getElementById("s").innerHTML = http1.readyState;


                }

---------------------------------------------------------------------

I have tried several techniques and have been following various tutorials especially at W3Schools. Any help would be appreciated on this.
