replacing all strings of numbers with a link

keiusui has asked for the wisdom of the Perl Monks concerning the following question:

I have a string that contains numbers and numerous other characters:

$s = "Numbers: 89, 90, 91, 180";
[download]

How would I replace all of the numbers in $s so that it's value becomes something more helpful:

$s = "Numbers: <a href=\"http://www.89.com\">89</a>, <a href=\"http://
+www.90.com\">90</a>, <a href=\"http://www.91.com\">91</a>, <a href=\"
+http://www.180.com\">180</a>";
[download]

Any help would be gratefully appreciated!

It's a straight global substitution, `$s =~ s!(\d+)!<a href="http://www.$1.com">$1</a>!g;` [download] After Compline, Zaxo	[reply] [d/l]

Awesome; thanks so much! I was missing the plus sign in my original code, so every single digit would be replaced instead of every string of digits. You rock.	[reply]
