I have a bunch of urls like
http://www.travelpod.com/travel-blog-entries/bassalleckj/japan_se_asia07/1191895200/tpod.htm
and I want to reduce them to end at the .com/
I don't want all the extra subdirectory information and page information like
travel-blog-entries/bassalleckj/japan_se_asia07/1191895200/tpod.htm
to be there. So in the above example I just want
http://www.travelpod.com/

Can someone give me the regular expression for this? I am using notepad++ regular expression engine.

Thanks!

]$ perl -we '
use strict;

my $url = "http://www.experts-exchange.com/Programming/Languages/Scripting/Perl/Q__26879493.html";

$url =~ s/(?:^(http.*\.com)).*$/$1/;

print $url,"\n";

'


Where

 $url =~ s/(?:^(http.*\.com)).*$/$1/;

 is the regex you're looking for.

This seems to find the entire string not just the ending

(http://[^/]+)/.*
