Hello Guys,

 

The .NET System.Text.RegularExpressions tools do not use /-delimited strings for regular expressions. Save that for javascript. Remove the leading / and the trailing /mg.

 

Also, the group (.*?) does not make sense. .* is already "optional in that the * allows 0 occurances of the . to match. Remove the ?.

 

Do you really want to match an empty string here? If not, use (.+) instead.

 

When you type this into a C# literal, use @-quoting rather than regular C/C++ style quoting. The leading @ avoids all processing of \ escapes. To get a quote in the string, type a double quote. For example:

 

string pattern = @"^a href=""(.*)"" class=I";

 

For your tester, just type the string contents: <a href="(.*)" class=I>, without the <> brackets shown here.

 

Thanks and Regards
