I try to extend a function in Java, particularly, a statement should be like:

$t in namespace:ownfunction()

Expected output of the function is a set of string, for instance, "aaa", "bbb", "ccc" - which would be recogised by XQuery.

What I do is returning the output of ownfunction() as a string e.g. "\"aaa\",\"bbb\",\"ccc\"" . But XQuery seems to recognise as a long string.

How should I return the output of ownfunction in order to let XQuery parser recogise as a set of String? I actually require this for applying with "in" operator.

Any ideas would be much appreciated.
