> We can roll our own predicates in jsonpath where you can use ? as the
> placeholder. The trick would be to either inline the functions in the string,
> and then do our own pre-parsing to replace those predicates to ?, eg
> {code}
> "$.person[?(@.role=='${headers.role}')]"
> {code}
> gets pre-parsed as
> {code}
> "$.person[?(@.role=='?')]"
> {code}
> And then we know that ${headers.role} is the simple funktion to execute as
> the predicate.
