   [.net] Text searching with regular expressions
  I have some sequence of chars, which looks like this:abc*******abc*******************abc****...abcSo I have "words" which are separated by the "abc" string. How can I get these words? I've tried regex match like "abc*abc" but it doesn't work.   
System.Text.RegularExpressions.Regex.Split(MyInputString, "abc");;  Wow, thanks a lot :) It works of course... However, I would be really glad if someone could show how to do the same thing using regex pattern   ;  The regular expression would be something like abc(.*?)abc - using . to match any character, * to match any number of them and ? to make the expression un-greedy.   ;  Yes, that works. Yet only finds the first pattern :(.For reading all results I use Matches collection and this pattern fills this collection with only the first occurence.   ;  Ah, I see. Assume you had the following input:abcHELLOabcWORLDabcGOODBYEabcThe first match here is abcHELLOabc, after which the cursor moves past the second abc. The next match after that is abcGOODBYEabc.I suppose if you wanted to use this method (rather than the more sensible Split) you could do something like this:Regex Expression = new Regex("abc(.*?)abc"); string Input = "abcHELLOabcWORLDabcTHISabcISabcFUNabc";int StartPosition = 0;for (; ; ) {// Try and make a match.var Match = Expression.Match(Input, StartPosition);if (!Match.Success) break;// We made a successful match!Console.WriteLine(Match.Groups[1].Value);// Move the start position along manually.StartPosition = Match.Index + Match.Length - 3;}Alternatively you could do something like this:Regex Expression = new Regex("abc(.*?)"); string Input = "abcHELLOabcWORLDabcTHISabcISabcFUNabc";var Matches = Expression.Matches(Input);...but you'd need to add some error checking to ensure that the original string ended in abc.   ;  Thanks a lot for this piece of code :)
