regex to remove an entire sentence that includes full stops, commas and spaces

I'm trying to build a regex to remove an entire sentence. The phrase is:

www.mydomain.com is the best, in fact it is the best. So visit mydomain.com

I tried the following

\www\.mydomain\.com is the best\, in fact it is the best\. So visit mydomain\.com/

But it doesn't help.

Any advice on this please?

That should be a forward slash at the start, not back. \w matches whitespace, when I suspect you mean it to be the start delimiter. Also, commas don't need to be escaped, so change \, to ,.

With those changes, it works for me.

*edit*If you're just matching a phrase, you can use \Q...\E to avoid needing to escape all the special characters in it.*

As you don't say what language you're using, here is a perl way to do it:

my $str = q!www.mydomain.com is the best, in fact it is the best. So visit mydomain.com!;
$str =~ s/.*?\.( |$)//;
print $str;

output:

So visit mydomain.com

Php version:

$str = 'www.mydomain.com is the best, in fact it is the best. So visit mydomain.com';
$str = preg_replace('/.*?\.( |$)/', '', $str);
echo $str;

This produces the same output.

there is a missing / at the beginning and the end.

in vi the following worls fine:

s/www\.mydomain\.com is the best, in fact it is the best\. So visit mydomain\.com//
