perl module to determine if a URL is valid?

[keiusui]

Hello, is there a standard or common Perl module used to determine if a URL is valid? I do not need to check whether the URL actually exists; I just need to check whether a URL entered by a user is a valid URL string or not.

For example, the Email::Valid module does a great job of simply checking whether a string is in valid e-mail format.

Thanks!

I use Regexp::Common::URI for finding URLs, and it can also validate URLs.

It comes with two caveats though: It doesn't understand https (only http), so I do something like this in my code:

use Regexp::Common qw /URI/;
my $re = $RE{URI}{HTTP};
$re =~ s/http/https?/g;

The second caveat is that it doesn't understand anchors (ie the part after a # pound sign).

use Regexp::Common qw /URI/;

    while (<>) {
        /$RE{URI}{HTTP}/  
             and  print "Contains an HTTP URI.\n";
    }

You can also use


$regexp = qr($RE{URI}{HTTP}{-scheme=>qr/https?/}{-keep});
