NAME

6       Regexp::Common::URI::fax -- Returns a pattern for fax URIs.
7

SYNOPSIS

9           use Regexp::Common qw /URI/;
10
11           while (<>) {
12               /$RE{URI}{fax}/       and  print "Contains a fax URI.\n";
13           }
14

DESCRIPTION

16   $RE{URI}{fax}
17       Returns a pattern that matches fax URIs, as defined by RFC 2806.  Under
18       "{-keep}", the following are returned:
19
20       $1  The complete URI.
21
22       $2  The scheme.
23
24       $3  The phone number, including any possible add-ons like ISDN
25           subaddress, a post dial part, area specifier, service provider,
26           etc.
27
28   $RE{URI}{fax}{nofuture}
29       As above (including what's returned by "{-keep}"), with the exception
30       that future extensions are not allowed. Without allowing those future
31       extensions, it becomes much easier to check a URI if the correct syntax
32       for post dial, service provider, phone context, etc has been used -
33       otherwise the regex could always classify them as a future extension.
