About Regular Expression Groups

Question

Hello All I want to break the string by using the Regular Expression: String:(!(2VH_AKTIVLENKUNG_UND_HSR) + !(ALLRAD) + (B47D20 + G011 B47D20 + G012 B48B20 + G011)) Output: !(2VH_AKTIVLENKUNG_UND_HSR) + !(ALLRAD) + B47D20 + G011 !(2VH_AKTIVLENKUNG_UND_HSR) + !(ALLRAD) + B47D20 + G012 !(2VH_AKTIVLENKUNG_UND_HSR) + !(ALLRAD) + B48B20 + G011 Thanks in Advance

The following is working OK but relies (as in one of your previous threads) on the comma separated list always being preceded by a space and a left bracket and for that combination to not occur earlier in the text: using System; using System.Text.RegularExpressions; class Test { static void Main() { string str = (!(2VH_AKTIVLENKUNG_UND_HSR) + !(ALLRAD) + (B47D20 + G011 B47D20 + G012 B48B20 + G011)); string regExp = @^$*(.*?)\s\((\w+\s*\+\s*\w+(\s*\w+\s*\+\s*\w+)*)$*$; Match m = Regex.Match(str regExp); string[] split = Regex.Split(m.Groups[2].Value @\s*); string[] output = new string[split.Length]; for(int j = 0; j { output[j] = String.Format({0} {1} m.Groups[1] split[j]); Console.WriteLine(output[j]); } Console.ReadKey(); } } The output is: !(2VH_AKTIVLENKUNG_UND_HSR) + !(ALLRAD) + B47D20 + G011 !(2VH_AKTIVLENKUNG_UND_HSR) + !(ALLRAD) + B47D20 + G012 !(2VH_AKTIVLENKUNG_UND_HSR) + !(ALLRAD) + B48B20 + G011
