Regexp::Common::URI::tel(3) User Contributed Perl Documentation Regexp::Common::URI::tel(3)
NAME
Regexp::Common::URI::tel -- Returns a pattern for telephone URIs.
SYNOPSIS
use Regexp::Common qw /URI/;
while (<>) {
/$RE{URI}{tel}/ and print "Contains a telephone URI.
";
}
DESCRIPTION
$RE{URI}{tel}
Returns a pattern that matches tel 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}{tel}{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.
