SYNOPSIS

use Regexp::Common qw /URI/;
while (<>) {
/$RE{URI}{fax}/ and print "Contains a fax URI.\n";
}

DESCRIPTION

$RE{URI}{fax}

Returns a pattern that matches fax URIs, as defined by RFC 2806. Under "{-keep}", the following are returned:

$1

The complete URI.

$2

The scheme.

$3

The phone number, including any possible add-ons like ISDN subaddress, a post dial part, area specifier, service provider, etc.

$RE{URI}{fax}{nofuture}

As above (including what's returned by "{-keep}"), with the exception that future extensions are not allowed. Without allowing those future extensions, it becomes much easier to check a URI if the correct syntax for post dial, service provider, phone context, etc has been used - otherwise the regex could always classify them as a future extension.
