How to C# - Regex to capture 2 bits of data in - ABC:(anything)

I need to parse (extract data - don't need to replace anything).

Test string: MAIN_HEADER:(ANOTHER_HEADER([DUMDUM:(BAH_123),OOPS,YEAH:(GAGA)])) need to output:

First component: MAIN_HEADER - only caps alpha and underscore
Second component: ANOTHER_HEADER:([DUMDUM:(BAH_123),OOPS,YEAH:(GAGA)]) - caps alpha, numbers, square and round brackets, commas, colons in any combination

I can extract second component with ^$([a-zA-Z0-9_:,\($\[\]]*)\)$ but I don't know how to do 2 different matches to split components.

Solution:

You may use this regex to extract 2 capture group as desired:

^([A-Z_]+):\s*\(([][A-Z0-9_(),:]+)\)

RegEx Details:

^:
([A-Z_]+): Match 1+ of uppercase letters or _ in capture group #1
:\s*: Match : followed by 0 or more whitespaces
\(: Match literal (
([][A-Z0-9_(),:]+): Match 1+ of uppercase letters or _ or digits or ( or ) or [ or ] or , or : in capture group #2
\): Match literal )
