RE: question on filtering a one-to-many relationship

Thx Michael,

I now understand my stupid mistake.  I should have tested solely on the name
instead of the sequence of names.

Thx for the quick reply !!

persons/person[some $n in children/child/name satisifies
matches(upper-case($n), upper-case($searchString))]

or if you prefer to avoid range variables,

persons/person[children/child/name[matches(upper-case(.),
upper-case($searchString))]]

(I'm not sure that applying upper-case() to a regular expression is
particularly good practice, however - for example it will change \w to \W).
