Here is a sample stylesheet that accepts a node set as a parameter.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                version="1.0">
				
	<xsl:output method="xml" version="1.0" indent="yes"/>
	<xsl:param name="state_list" select="/.."/>

    <xsl:template match="/">
		<states>
			<names>				
				<xsl:apply-templates select="$state_list/descr"/>				
			</names>
			<capitals>
				<xsl:apply-templates select="$state_list/capital"/>
			</capitals>
		</states>
	</xsl:template>											

	<xsl:template match="descr">
		<description>
			<xsl:value-of select="."/>
		</description>
	</xsl:template>		
		
	<xsl:template match="capital">
		<capital_city>
			<xsl:value-of select="."/>
		</capital_city>
	</xsl:template>
</xsl:stylesheet>


The .NET code to pass a parameter:

			XmlDocument doc = new XmlDocument();
			doc.Load(Server.MapPath("test.xml"));
			
			XmlDocument stateDoc = new XmlDocument();
			stateDoc.Load(Server.MapPath("states.xml"));
			

			System.Xml.XPath.XPathNavigator nav = stateDoc.CreateNavigator();
			System.Xml.XPath.XPathNodeIterator iter = nav.Select("/states/state");

			XslTransform trans = new XslTransform();
			trans.Load(Server.MapPath("test.xslt"));

			XsltArgumentList args = new XsltArgumentList();
			args.AddParam("state_list",String.Empty,iter);

			Response.ContentType = "text/xml";
			trans.Transform(doc,args,Response.OutputStream);


states.xml:

<?xml version="1.0" encoding="utf-8" ?> 
<states>
	<state>
		<abbrev>GA</abbrev>
		<descr>Georgia</descr>
		<capital>Atlanta</capital>
	</state>
	<state>
		<abbrev>TN</abbrev>
		<descr>Tennessee</descr>
		<capital>Nashville</capital>
	</state>
	<state>
		<abbrev>AL</abbrev>
		<descr>Alabama</descr>
		<capital>Montgomery</capital>
	</state>		
</states>



test.xml:

<?xml version="1.0" encoding="utf-8" ?> 
<root/>
