NAME

Regexp::Common::URI::fax -- Returns a pattern for fax URIs.  

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.
