 Okay, I'll bite. The trick is that we're doing a straightforward mapping of one tree to the other, only performing a bit of testing to determine (a) where to quit, and (b) how to label our output as we go. This stylesheet-- <xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:output method="html" indent="yes" /> <xsl:param name="selection">Topic 2.1.1</xsl:param> <xsl:template match="menuItem">
<div>
<xsl:apply-templates select="description"/>
<xsl:if test="$selection = descendant::description">
<!-- We keep going if we're open. We're open if $selection
corresponds to our description or that of one of our
descendants -->
<xsl:apply-templates select="menuItem"/>
</xsl:if>
</div>
</xsl:template><xsl:template match="description">
<span>
<xsl:choose>
<xsl:when test="$selection = ../descendant::description">
<!-- We use the same test as above to determine our label, except
it's our parent menuItem that we're descending from. -->
<xsl:text>O </xsl:text>
</xsl:when>
<xsl:otherwise>
<!-- otherwise it's closed -->
<xsl:text>C </xsl:text>
</xsl:otherwise>
</xsl:choose>
<xsl:apply-templates/>
<!-- Brian wanted sth different, but we'll just go for the
description element's content to finish our label. -->
</span>
</xsl:template></xsl:stylesheet> run on Brian's source (simplified): <?xml version="1.0"?>
<menu>
<menuItem id="docid1">

<div><span>O Topic 2</span>
<div><span>O Topic 2.1</span>
