Hello, everybody,
do you know how to use this Grouping Construct?
(?> )
I've found its reference on MSDN, but still can not understand it totally.
The following is its description:
Nonbacktracking subexpression (also known as a "greedy" subexpression). The
subexpression is fully matched once, and then does not participate piecemeal
in backtracking. (That is, the subexpression matches only strings that would
be matched by the subexpression alone.)
Can anybody tell me how to use it? If someone knows, please show me an example:)
Thanks a lot!
Best regards,
Laser Lu.

You can use the grouping construct for extracting parts of a string. For
example, say you want to extract the value of color (i.e. "red") from the
following string:
string description color="red"
You can do this using the regular expression: color="(?<color >\S*)"
The following code uses the regular expression and the Match.Groups property
to print out the value "red":
Regex rgx = new Regex(@"color=\ ""(?<color>\S*) \""");
Match m = rgx.Match("a string description color=\"red\"") ;
if (m.Success)
{
string color = m.Groups["color"].Value;
Console.WriteLi ne(color);
}

Hey Jakob, you used construct "(?<name> )", not "(?> )". They are not the
same:)
Please refer to http://msdn.microsoft.com/library/de...constructs.asp I am not sure I understand your question. "(?> )" defines af group.
In my example I used "(?> )" to define a group called "color".
