perhaps Regexp::Common is what you are looking for:
use strict;
use warnings;
use Regexp::Common qw /URI/;
my $http_and_https = qr{$RE{URI}{HTTP}{-scheme=>'https?'}};
while (my $line = <DATA>) {
while ($line =~ m#($http_and_https)#gc) {
print $1 , "\n";
}
}
__DATA__
a) black and white stuff http://test.com/testing" blah blah
b) rain in spain blah blah https://chewu.to/x7w
c) http://udsu.de/823; test this
d) Just testing ... http://go.to/xi8jwe #goodtimes
e) Super dooper. Looks nice! http://22.com/xx / http://p.de
Output:
http://test.com/testing
https://chewu.to/x7w
http://udsu.de/823;
http://go.to/xi8jwe
http://22.com/xx
http://p.de

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
