I'm clearly not clear again.
xml
<level1 id='l1'>
<h1>Level1</h1>
<level2 id='l2'>
<h2>Level2</h2> <!-- bad navPoint 1 -->
<level3 id='l3'> <!-- good navPoint 2 -->
<h3>level3</h3>
<note id="noteId"> <!-- navLabel target -->
<p>Note content</p>
</note>
</level3>
</level2>
</level1>
(My definitions)
level3 is a 'direct descendant' of level2
level3 is not a 'direct' descendant of level1
(since level2 intervenes).
I.e. I'm only interested in the wrapper levels (level1 level2 level3)
Testing with
<xsl:variable name='x' select='/level1/level2'/>
<xsl:variable name='y' select='/level1'/>
<xsl:template match="/">
<xsl:message>Y is a child of X:<xsl:value-of select="count($x/*|$y) =
count($x/*)"/></xsl:message>
<xsl:message>X is a child of Y:<xsl:value-of select="count($x//*|$y) =
count($x/*)"/></xsl:message>
Gives
Y is a child of X:false
X is a child of Y:false
I.e. its implying that level2 is not a direct descendant of level1,
which according to my definitions, it is.
Is that any clearer David?
