I have a document where each child of the root element establishes a
unique content with regard to the output result (in this case,
corresponding to InDesign frames).
For a given descendant of one of these elements I need to know if there
are any following elements within the same context. So simply doing
following::* won't work and the following elements I'm checking for need
not be siblings of the current element.
The solution I arrived at is:
<xsl:variable name="myDitaAncestor" select="ancestor::dita"
as="element()*"/>
<xsl:variable name="followingWithinDita" as="element()*"
select="following::*[count(ancestor::dita | $myDitaAncestor) = 1]"
/>
This works but I'm wondering if there's a better solution, either one that
is more efficient or one that is more elegant?
I don't know if it's more efficient or more elegant, but you could do:
$myDitaAncestor//* >> current()
Keying elements by their <dita> ancestor might help, eg
key name="elems-by-dita" match="*" use="generate-id(ancestor::dita)"
key('elems-by-dita', $dita-id) >> current()
where $dita-id is the generate-id() of the dita ancestor passed down
as a tunnelled param.
