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
