$AuthorId)][not($CategoryId) or (category_id = $CategoryId)]

Thanks Andrew, that looks exactly like what I'm looking for, but I get a
big ole error:
Expected token ')', found ','.
//blog[author_id = ($AuthorId -->,<-- author_id)[1]][category_id = ($...
Any ideas?
Is that an XSLT 1.0 processor giving that error?
I'm not sure what ($AuthorId, author_id) is meant to do?
In XSLT 2.0 it is simply a sequence consisting of $AuthorId and author_id.
The trailing [1] then takes the first item in that sequence thus if
$AuthorId is not the empty sequence then author_id is compared to the value
of (the first item) $AuthorId and if it the empty sequence then it is
compared to author_id itself which is always true, basically not doing any
filtering at all.
