Search for : =>.*(\[|\]).*=>

Explanation:

• .* - zero or more characters
• (one|two) - one or the other
• \[ - the character [ escaped.

Screenshot from notepad++:

• Ctrl+F
• Find what: (?<==>)[^=>]*[][][^=>]*(?==>)
• CHECK Wrap around
• CHECK Regular expression
• Find All in Current Document

Explanation:

(?<==>) # positive lookbehind, make sure we have => before
[^=>]* # 0 or more any character that is not = or >
[][] # character class, matches [ or ]
[^=>]* # 0 or more any character that is not = or >
(?==>) # positive lookahead, make sure we have => after

If you want to catch also =>, use: =>[^=>]*[][][^=>]*=>
