Default Problems parsing XML Feed in Javascript

I was initially looking for a solution to parse a remote XML feed into an ASP.NET page using JavaScript, and the code below displays a solution.

The code in this thread works great at pulling nodes from an external XML feed. I have an internal client-side "news scroller" script (JavaScript) that I want to display some of the nodes from the server-side code.

So can I pull XML nodes from an external XML feed, declare variables from that code, and then use those server-side variables within client-side code?

Something like this:
    var xmlDoc;
    xmlDoc = new ActiveXObject("Msxml2.DOMDocument.3.0")
    xmlDoc.setProperty("ServerHTTPRequest", true) 

    if (xmlDoc.load("http://codeamber.org/a1xl04act/amberalert.xml") == false)
        Response.Write("Failed to load xml");
var amberDescription = xmlDoc.selectSingleNode("//FullText").text;//<<----CAN I PULL THIS INTO CLIENT-SIDE CODE???

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <title>Pull XML  Feed</title>
<script type="text/javascript" language="javascript">
var pausecontent=new Array()

//These need to be dynamically pulled from existing XML feeds:
pausecontent[0]='<strong><a href="amberalert.aspx">Amber Alert:</a></strong> ' + amberDescription + ' <a href="amberdetails.aspx">Learn more #62;#62;</a>'
pausecontent[1]='<strong><a href="anotherfeed.aspx">Another Feed:</a></strong> ' + anotherfeedDescription + ' <a href="anotherfeed.aspx">Learn more #62;#62;</a>'
    <h1>Pull XML Feed</h1>
    <p><b>Alertstatus:</b> <span id="Alertstatus"><%=xmlDoc.selectSingleNode("//Alertstatus").text %></span><br />
    <b>FullText:</b> <span id="FullText"><%=xmlDoc.selectSingleNode("//FullText").text %></span><br />
    <b>Alertinfo:</b> <span id="Alertinfo"></span><br />
    <b>AlertState:</b> <span id="AlertState"><%=xmlDoc.selectSingleNode("//Alertinfo/@states").text %></span><br />
    <b>Victim:</b> <span id="Victim"><%=xmlDoc.selectSingleNode("//Victim/@name").text %></span>
    <script type="text/javascript">
        new pausescroller(pausecontent, "scroller", "someclass", 8000)
I don't know much about using client-side code in conjunction with server-side code, so if anyone can let me know if this is possible, that would be great. Thanks.
