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>            
                        
                                        </xsl:when>
