man Regexp::Common::URI::tel () - Regexp::Common::URI::tel -- Returns a pattern for telephone URIs.
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.\n"; }
DESCRIPTION
$RE{URI}{tel}
Returns a pattern that matches tel URIs, as defined by RFC 2806. Under CW{-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. As above (including what's returned by CW{-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.
