Clearly I need to do a closer reading of the XPATH 2 spec (or maybe buy
*and read* Mike Kay's book). How did I not know about the "<<"
(node-before) and ">>" (node-after) operators?
Cheers,
E.

I think this is an FAQ but my situation may be slightly different. In any
case, if it's an FAQ, maybe my asking it will help.
This is in a DITA context, where I can know for any element whether it is
a block or not a block (because in DITA all elements have a base type
that
is inherently block or not block).
I have the situation where a wrapper element may contain any combination
of text, non-block elements, or block elements.
I need to find either all the nodes up to the first block or determine
that there are none and get the first block.
I think this will work:
select="node()[. << current()/*[lc:isBlock(.)][1]"
But it is XSLT 2.0 only.
For XSLT 1.0 I might do something like:
select="node()[generate-id(following-sibling::*[lc:isBlock(.)][1]) =
generate-id(current()/*[lc:isBlock(.)][1])]"/>
Where the lc:isBlock() function returns true if the element provided is a
DITA block element.
This seems to pass all my tests but I'm wondering if there's a better way
to make this check?
I also realized that I can use the $textBeforeBlocks variable to then
process any remaining blocks (because I will have already output the text
before blocks):
<xsl:when test="$hasTextBeforeBlocks">
<xsl:apply-templates select="node() except($textBeforeBlocks)"/>
</xsl:when>
That includes the block element ... you might try using ">>" in a way
similar to how I used "<<" above if you didn't want to include the
block element itself.
I hope this helps!
