for xml type we have xpath function for these type of queries.
unfortunately, no analog for json type exists as of yet. so, here our
our options:
*) pull to client side and filter there
*) search textually (say, by regular expression) and hope for the best
*) implement backend function in a language that speaks json, or can
be extended to do so. pl/v8 and p/python are both noteworthy, but
almost all languages have json features of some kind. your function
will do simple test and return bool for example.
