I think I must be forgetting something fundamental, but I'm not figuring
out how to do something that should be fundamental, I think.
Using XSLT2, I'm examining all the items in a key() map to see if any
entries in the map have more than 1 item. I'm doing this by iterating over
the keys. I'm then producing a boolean for each iteration and capturing
the sequence of booleans in a variable.
My thinking was that I could then just AND the sequence to determine if
any of the items had more than 1 item. But I see that boolean() and not()
don't operate on sequences of booleans. Hmph.
I realize thinking about it now that I can only put true() items in my
sequence and then just check the first one.
But my question still remains: is there a built-in way to apply boolean
operators to a sequence of booleans or would I need to write my own
function? Obviously, if I was writing my own function I'd just use
recursion to walk the sequence, which would allow early termination for
and() and or().
Have I missed something obvious or not so obvious? I am I just thinking
about this particular problem the wrong way?
Thanks,
Eliot
