NAME

HTML::RobotsMETA - Parse HTML For Robots Exclusion META Markup

SYNOPSIS

use HTML::RobotsMETA;
my $p = HTML::RobotsMETA->new;
my $r = $p->parse_rules($html);
if ($r->can_follow) {
  # follow links here!
} else {
  # can't follow...
}

DESCRIPTION

HTML::RobotsMETA is a simple HTML::Parser subclass that extracts robots exclusion information from meta tags. There's not much more to it ;)

Currently HTML::RobotsMETA understands the following directives:

ALL

NONE

NOINDEX

NOFOLLOW

ARCHIVE

There also might be more obscure directives that I'm not aware of.
