rex for extract codes

[indeed_2000]

hi
what is the rex for extract all brackets contain this pattern
[AB_123] [ZXY_987]

1-check all brackets if start with AB_ extract this AB_123
2-check all brackets if start with ZXY_ extract this ZXY_987
3-put all this in single field that call "Codes"

any idea?
thanks
