How do I create a regex in Emacs to capture text between double square brackets?

Question

I want to create a regex in Emacs that captures text between double square brackets. I found this regex. It allows to find string betwen square brackets but it includes the square brackets : ``` "$$\[$[^][]+$$$$\[$[^][]+$\]$?\]" ``` How can extract the string between double square brackets excluding the square brackets?

Accepted Answer

This regexp will select the square brackets but by using group 1 you will be able to get only the content: `"$$\[$.*$$$\]"`
