Return Data Regex Doesn't Isolate - Yikes

[Garibaldi]

Folks,

I'm having a bad regex day and can sure use your help, please..

I have a Regex expression that works fine. It's purpose is to isolate all
data from the start of a string begining with 200~ to the end of the string
but before the start of the next 200~. Here's the regex expression and test
data:

(?ms)^200~(.*?) (?=^200~)

Here's some test data

000000000000000 00000
200~11111111111 111111
222222222222222 22222222222222
3333333333333
200~44444444444 4444444444444
555555555555555 555555555555555 555
66666666
200~77777777777 7777777
888888888888

The regex will return 200~ plus all ones, twos, threes as a group then 200~
plus all fours, fives, sixes as a group

Problem
---------
Now I need to do the reverse. I need to return all the data the preceding
regex doesn't return. IOW, I need to return all the zeros and 200~ plus all
the sevens and all the eights as a group. I want to execute "NOT
(?ms)^200~(.*?) (?=^200~)"

Sure could use a pointer to the correct starting point or any suggestion
that will help me reach my goal.

Thanks in advance

Re: Return Data Regex Doesn't Isolate - Yikes

I had some rather large explanation of how to do it procedurally, but then I
thought,
"Justin, get off your arse and write some regular expression magic!". So here
you go.

using System;
using System.Text.Reg ularExpressions ;

public class SuperRegex {
private static string stuff =
@"0000000000000 0000000
200~11111111111 111111
222222222222222 22222222222222
3333333333333
200~44444444444 4444444444444
555555555555555 555555555555555 555
66666666
200~77777777777 7777777
888888888888";

private static void Main(string[] args) {
Regex regex = new Regex("(?ms)(?: \\A|^200~)(.*?) (?=^200~|\\Z)") ;
MatchCollection matches = regex.Matches(s tuff);
for(int i = 0; i < matches.Count; i++) {
Console.WriteLi ne();
Console.WriteLi ne(matches[i].Value);
Console.WriteLi ne();
}
}
}

You could just call Regex.Replace with the same expression and an empty
string as the replacement if you didn't need to access any of the match
properties (index, groups, etc.).
