Hi,

Here is the code you are looking for.  This ASP script currently takes two
parameters (to demonstrate how to have more than one), searchValue1 and
searchValue2.  So, if you call the asp 'searchXML.asp' you could pass params
to it by using:

  searchXML.asp?searchValue1='foo'&searchValue2='bar'

So within your html form, you would have:

  <form name="yourForm" action="searchXML.asp">
   <input type="text" id="searchValue1"/>
   <input type="text" id="searchValue2"/>
   <input type="submit"/>
  </form>

The ASP code would look like this (using msxml3):


<% Response.Buffer=True %>
<% Dim xml
   Dim xsl
   Dim template
   Dim processor

   Set xml = Server.CreateObject("MSXML2.FreeThreadedDOMDocument.3.0")
   xml.async = false
   xml.load (Server.MapPath("yourXMLFile.xml"))

   Set xsl = Server.CreateObject("MSXML2.FreeThreadedDOMDocument.3.0")
   xsl.async = false
   xsl.load (Server.MapPath("yourXSLFile.xsl"))

   Set template = Server.CreateObject("MSXML2.XSLTemplate")
   template.stylesheet = xsl
   set processor = template.createProcessor()

   processor.input = xml

   searchValue1 = Request.querystring("searchValue1")

   if searchValue1 <> "" then
     processor.addParameter "param1", searchValue1
   end if


   searchValue2 = Request.querystring("searchValue2")

   if searchValue2 <> "" then
     processor.addParameter "param2", searchValue2
   end if

   processor.transform()

   Response.write (processor.output)
%>

And finally, within your stylesheet you need accept the params with some
top-level elements:

<xsl:stylesheet...
<xsl:param name="searchValue1"/>
<xsl:param name="searchValue2"/>

You can then access them using $searchValue1 and $searchValue2
