Regex for removing a specific BBCode from a string

Question

I\'m trying to write a simple method for removing specific BBCodes from an input string.

For example, where I have an input of:

string input = \"[b]H         


        

Answer 1

The below regex would capture the string Hello World! inside the second group.

^(.*?)((?<=])[^[]*)(.*)$

DEMO

So replace all your input string with the second captured group.
