如何在括号正则表达式中获取括号外的字符串

I need help trying to get regex to work with double brackets

currently i have this for the regex

(\\[.*?\\])

that allows me to get everything inside a bracket,

HOWEVER my string has double brackets

[DATA1[OTHERDATA]RUBBISH]

the output I get is

[DATA1[OTHERDATA]

is the a way of getting the full bracket including the bracket inside?

    Keeping things nice and simple. A greedy match should do the trick:

    /\[(.+)\]/
    

    the .+ will match any character, but it'll stop at the last ], so the match will be "DATA1[OTHERDATA]RUBBISH"

    Demo

    Breakdown is really simple:

    • \[: Matches literal [
    • (.+): Match (and capture) all characters - including opening and closing brackets
    • \]: Match literal ]

    Regardless of how many nested brackets you have the results are the same:

    [data[foo][bar][eve[n]]more]
    //match:
    data[foo][bar][eve[n]]more
