Regex to select all spaces between a special enclosure-CodePudding

I am trying to write a regex for Javascript that can select all whitespaces in between AMPScript brackets, the syntax for the Lang is something like this

%%[


set @truth = 'this is amp'

IF @truth == 'this is amp' THEN
set @response = 'amp rocks'
ELSE
set @response = '️...'
ENDIF

]%%

So far, I am able to select all the characters inside the given brackets using this expression:

%%\[(\s|.)*?\]%%

But this selects all the characters inside the enclosure, is there a method I can use to only select spaces/new lines/tabindents only?

Thanks in advance!

I believe this is what you want:

(?<=%%\[(\s|.)*)\s*(?=(\s|.)*\]%%)
