XML : Redirecting to xml with query string in asp.net

I am doing a Response.Redirect to below given xml document with a query string parameter.

   Response.Redirect(@"../temp/output.xml?location=newlocation");    

What I want is that the value of location attribute should be replaced with the value I pass in query string parameter. The problem is when I do a response.redirect to xml the c# server code which modifies the xml document does not executes for the obvious reason that xml file does not runs any server code.

Can anyone please suggest a solution for this.

Xml File

  <?xml version="1.0" encoding="utf-8"?>  <products xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="products:noNamespaceSchemaLocation">  <store id="BND088412">    <display-name>test</display-name>  </store>    <product location="test">       <length units="minutes">100</length>       <title>Microsoft Excel</title>    </product>    <product location="test">       <length units="minutes">300</length>       <title>Microsoft VBA</title>    </product>  </products>    

Thanks & Regards
