About Regular Expressions in Multiple Groups

Question

Hello All I want to break the string by using the Regular Expression: String: (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + (B47D20 B48B20 B57D30 B58B30 N63B40 N63B44 N74B66 XB1141))  Output:  (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + B47D20)  (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + B48B20)  (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + B57D30)  (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + B58B30)  (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + N63B40)  (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + N63B44)  (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + N74B66)  (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + XB1141) Thanks in Advance

This one can be done relatively easily as follows. However it relies 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 = (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + (B47D20 B48B20 B57D30 B58B30 N63B40 N63B44 N74B66 XB1141)); string regExp = @^$*(\w+\s*\+\s*.*?)\s\((\w+(\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: (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + B47D20) (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + B48B20) (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + B57D30) (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + B58B30) (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + N63B40) (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + N63B44) (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + N74B66) (G011 + !(2VR_2_ACHS_LUFTFEDERUNG) + !(2VS_MASTERPIECE_ARBEITSNAME) + XB1141)
