Answer 1

If you sure that both starting and trailing special symbol must occur and you don't want them to be in a result, you can use positive look back ((?<=(your symbols here))) and positive look ahead ((?=(your symbols here))) for specified characters.

Complete answer will look like this:

(?<=(\[{0}\])).*(?=(\[\/{1}\]))
