Try with this:

"<a href=\\s*([^>]*)\\s*>\\s*"

An example:

string s;
Regex r;
Match m;
//
s = @"<p>Esto es una prueba <a href='http://www.elguille.in fo/'>el Guille</a>
Más cosas.</p>";
r =new Regex("<a href=\\s*([^>]*)\\s*>\\s*");
//
m = r.Match(s);
if( m.Success)
Console.WriteLi ne(m.Result("$1 "));
else
Console.WriteLi ne("No hay coincidencias." );

--
Nos vemos.

try this:
r = New Regex("<a href=\s*[""']([^\s]*)[""']\s*>")

In C#:
r = new Regex("<a href=\\s*[\"']([^\\s]*)[\"']\\s*>");

Hi, I am replaceing a big string using different regular expressions (see some example at the end of the message). The problem is whenever I apply a "replace" it makes a new copy of string and I want to avoid that. My question here is if there is a way to pass either a memory stream or array of "find", "replace" expressions or any other way to avoid multiple copies of a string. Any help will be highly appreciated

I have a regular expression (^(.+)(?=\s*).*\1 ) that results in matches. I would like to get what the actual regular expression is. In other words, when I apply ^(.+)(?=\s*).*\1 to " HEART (CONDUCTION DEFECT) 37.33/2 HEART (CONDUCTION DEFECT) WITH CATHETER 37.34/2 " the expression is "HEART (CONDUCTION DEFECT)". How do I gain access to the expression (not the matches) at runtime? Thanks, Mike

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
