Well the main suggestion is to do server-side transformation, not 
client-side. How you do that depends on the server-side framework and 
XSLT processor API you have available.
In terms of XSLT you would define a global parameter for each argument 
you want to pass in the query string part of the URL and then you use 
those parameters to filter elements e.g.

<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   version="1.0">

   <xsl:param name="name" select="''"/>

   <xsl:template match="/">
     <html lang="en">
       <head>
         <title>Example</title>
       </head>
       <body>
         <xsl:apply-templates select="root/person[$name = '' or @name = 
$name]"/>
       </body>
     </html>
   </xsl:template>

   <xsl:template match="person">
     <!-- add content here to output persons -->
   </xsl:template>

</xsl:stylesheet>

The server-side framework (e.g. ASP or JSP or PHP for instance) allows 
you to read out the query string. The API of the XSLT processor then 
allows you to set the global parameter named 'name' before you run the 
transformation.
