Let's say I have a line like this:

std::string str = "<html><body><a href=\"url\">name link</a><a href=\"url\">name link</a></body></html>";

How to get the contents of a link using regular expressions?
There seems to be no problem with the regular expression itself:

std::string str = "(.*)(<a href=\">)(\\w*)(<\/a>)";

But is it possible in C++ to get the contents of a link? Those. position in a string, for example.
In php, for example, this is possible.
Or for such purposes it is necessary to use std::string::find?

And if there is
<a lang="fr" href="url"></a>
then what?
and in the regular expression (\\w*) it will not catch your "name link" ;)
so there are problems with the regular expression
