recursive help

i have an xml document that needs to be transformed which seems to perfect for recursion. (this is my first attempt at trying this) it is essentialy a nested menu system of links. the basic logic is it checks to see if a node has a child, if it does print a header otherwise a link.    i built the xml document using recursion, i just can't figure out how to transform it useing the same technique. samples of both xml and xslt 


xml doc:
<?xml ?>
<standards>
   <standard id="1" name="test">
        <standard id ="32" name="test" />
        <standard id ="45" name="test>
             <standard id ="23" name="test" />
             <standard id ="12" name="test" />
         </standard>
   </standard>
</standards>

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

	<xsl:template name="buildmenu">
		<xsl:param name="foo" />
		<xsl:choose>
			<xsl:when test="position()!=last()">
				<xsl:choose>
					<!-- test to see if foo has children 
						if so print header -->
					<xsl:when test="count($foo) != 0">
						 has child print header 
						<h2><xsl:value-of select="@name" /></h2>
						 <xsl:call-template name="buildmenu">
							<xsl:with-param name="foo" select="$foo" />
						</xsl:call-template> 					
					</xsl:when>
					<xsl:otherwise>
						<!-- no children print link -->
						<a><xsl:attribute name="href">addlinkinfol8r</xsl:attribute><xsl:value-of select="@name" /></a>
						 <xsl:call-template name="buildmenu">
							<xsl:with-param name="foo" select="$foo" />
						</xsl:call-template> 
					</xsl:otherwise>
				</xsl:choose>
			</xsl:when>
			<xsl:otherwise>
				<a><xsl:attribute name="href">addlinkinfol8r</xsl:attribute><xsl:value-of select="@name" /></a>			
			</xsl:otherwise>
		</xsl:choose>
	</xsl:template>
	
	<xsl:template match="standards">
		<xsl:call-template name="buildmenu">
			<xsl:with-param name="foo" select="standard" />
		</xsl:call-template>
	</xsl:template> 
	
	 <!--<xsl:template match="standards">
		<xsl:for-each select="standard">
				<a><xsl:attribute name="href">addlinkinfol8r</xsl:attribute><xsl:value-of select="@name" /></a>			
		</xsl:for-each>
	</xsl:template> -->

</xsl:transform>
