Input string:

[Wsg-Fs]-A-A-A-Cgbs-Sg7-[Wwg+s-Fs]-A-A-Afk-Cgbs-Sg7

Desired output is a string array:

[Wsg-Fs] A A A Cgbs Sg7 [Wwg+s-Fs] A A Afk Cgbs Sg7

If I split the input string with - as delimiter, the string within square brackets also gets split.

How do I split the string such that - within square bracket should be ignored?

I could find some similar posts trying to ignore delimiter enclosed in quotes, however I have not been able to apply those solution to my problem.

Any suggestion would be really helpful. Thanks!

    Assuming there are no nested square brackets, you can use the following to only match - characters that are outside of square brackets:

    -(?![^\[]*\])

    Example: http://regex101.com/r/sX5hZ2

    This uses a negative lookahead, with the logic that if there is a closing square bracket before any opening square brackets, then the - that we tried to match is inside of brackets.
