Help parsing an XML response from a SOAP server

I've created a page that now sends off a proper request to a SOAP server and gets a response back. The SOAP request is to log into the system. The response has a token code in the XML that I need to use in all subsequent requests.

Today, the page displays the entire response as text on the web page. What I need to do next is parse the response and store the token as a variable.

I've read some online tutorials and tried to hack together some code. But its just not working.

In the code below, the submit button calls the makeSoapRequest() function. That function then calls the parseXMLDocument() function. This new parseXMLDocument() function is where I am having problems.

Any assistance would be greatly appreciated.

----Here is the code for the page--------

<script language="javascript">

function makeSoapRequest(form){
      // create the payload of the SOAP request

var token = xmlDoc.getElementByTagName('token').something

Like nodeValue or text or value - I cannot remember off the top of my head

Sorry - I mean:

var strToken = xmlDoc.getElementsByTagName('token')[0].text;
alert(strToken);

It appears to be .text from what I've found. However, I tried value and NodeValue as well, just to be thorough.

I'm still getting at error at this line saying "Object doesn't support this property or method."

      var token = xmlDoc.getElementByTagName("token").value;

Here is the complete code as it is now.
