Is there an equivalent SQL IN clause in XQuery?

Question

Is there something like a SQL IN clause in XQuery? For example, I want to do something like this:

 where $x/lotClosedYn in ('Y','N') 

using the IN keyword gives an error, I use saxon to handle XQuery.

Answer 1

Use = . It works on a set basis, therefore ("Y", "A", "B", "C") = ("Y") returns true.
