I am looking for a regex rule to match everything inside square brackets, including the brackets and ignoring the possible brackets inside. E.g. from:
[value] in the [text[42]] and [1[2[3]]]!
I need to extract [value], [text[42]] and [1[2[3]]].
I use
\[(.*?)\]
Here are more expamples - https://regex101.com/r/Xp4ghi/1
P.S. I am going to use it in .NET
You can use
\[(?>[^][]+|(?<c>)\[|(?<-c>)])+]
See the regex demo. Details:
\[ - a [ char(?>[^][]+|(?<c>)\[|(?<-c>)])+ - one or more occurrences of
[^][]+| - one or more chars other than ] and [, or(?<c>)\[| - a [ char and a value is pushed onto Group "c" stack, or(?<-c>)] - a ] char and a value is popped off the Group "c" stack] - a ] char.
