Try the split http://msdn.microsoft.com/en-us/library/8yttk7sy.aspx[method].
Basically, something like string[] substrings = Regex.Split(str, "xxx"); should do.

Solution 1

You don't even need regular expressions for such a task, just using the String.Split[^] method is enough.

I second that unless OP is a big Regular Expression fan. ;)

And it's a better solution, my 5

Better solution than using Regular Expressions in a trivial case such as this! 5+

Actually my req is bit complex ..

If your case isn't more complex than stated in your question I'd advise you to go with CPallini's solution here[^].

Just in case you'd like to know anyhow how a regular expression would look like to achieve your goal:

(.*?)(xxx|$)

This expression was verified to work with the free tool Regular Expression Designer[^].

It will give you four matches instead of three where the last match is the empty statement followed by the end of line. This is about the simplest regular expression I could come up with to achieve your goal.

Regards,

Manfred

P.S.: If anybody has a shorter variant please let me know. :)
