RE: [xsl] Hierarchy problem

["McNally, David" <David dot McNally at moodys dot com>]

Does this do what you want - it checks if the node in $point2 is the parent
of the node in $point1 (I think):

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text"/>
	
<xsl:template match="/">
<xsl:variable name="point1" select="//*[@id='noteId']"/>
<xsl:variable name="point2" select="//level2[@id='l2']"/>
<xsl:choose>
	<xsl:when test="$point1/.. = $point2">
		<xsl:text>Yes</xsl:text>
	</xsl:when>
	<xsl:otherwise>
		<xsl:text>No</xsl:text>
	</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>

I don't think this would be complicated by using document() in the variable
definitions (but could be wrong).
