About Regular Expressions in Multiple Groups

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 < split.Length; 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)
