I thought about it, but without viewing source of resource_int_value not know how to behave resource_int_value on string value.
Now I looked up and remade to test "start"/"end" values for string "search", then if fail - get int value.
Thanks for review.

In future we need made allowing search of both start and end, maybe and search for multiple labels with start based on previous
slice and.
