HTML::RobotsMETA - Parse HTML For Robots Exclusion META Markup
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...
}
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:
Creates a new HTML::RobotsMETA parser. Takes no arguments
Parses an HTML string for META tags, and returns an instance of HTML::RobotsMETA::Rules object, which you can use in conditionals later
Returns the HTML::Parser instance to use.
Returns callback specs to be used in HTML::Parser constructor.
Tags that specify the crawler name (e.g. <META NAME="Googlebot">) are not handled yet.
There also might be more obscure directives that I'm not aware of.
