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?
well if you know there's a dita acestor,
count(ancestor::dita | $myDitaAncestor) = 1
can be written
ancestor::dita is $myDitaAncestor
you could also do
following::* union $myDitaAncestor//*
but I'd guess that's less efficient.
Something tells me you should be using a key, but keying the dita
elements on all its descendents sounds a bit expensive.
