With a structure such as
<bodymatter>
<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>
....
I need to check that the node with id=noteId
is (or is not) a direct descendant of another node (e.g. level2[id='l2'])
or if there are intervening levelX elements.
The DTD is roughly html like, with wrappers as shown at each level.
In the above case navLabel target is not a direct descendant of navPoint 2,
but is a direct descendent of navPoint 3.
All I actually have is
for the navLabel node,
<xsl:variable name= 'navLabelNodeID'
select='generate-id(document(content/@src)/text/@src)'/>
for the navPoint node,
<xsl:variable name='navPointNode'
select='document(id(@mapRef)/content[1]/@src)'/>
both point into the same document, with the src attribute being a fragment
identifier.
I'm even unsure if the fragment identifier will actually retrieve the
sub-document,
but that's a seperate problem I think I can get round.
Any help appreciated.
TIA, DaveP
