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.\n";
           }

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.
