Dear all,
I'm trying to filter a sequence using a predicate that involves a node set.
What I actually want to do is something like
$string-sequence[. = //@xml:id]
i.e. get all items of a sequence that occur as an xml:id attribute somewhere
in the document.
As that gives me the error message "XPTY0020: Cannot select a node here: the
context item is an atomic value" (with Saxon 9.1), I tried
$string-sequence[. = (for $n in (//@xml:id) return xs:string($n))]
or even
('foo', 'bar')[. = (for $n in (//@name) return 'foo')]
where the latter should actually return something like ('foo', 'foo', ...),
and ('foo', 'bar')[. = ('foo', 'foo')] works, of course.
My current workaround is translating the string sequence to a sequence of text
nodes, but why doesn't it work with a sequence of atomic types?
Thanks for any help,
Christoph
