=head1 NAME

XML::RSS::Headline::UsePerlJournals - XML::RSS::Headline Example Subclass

=head1 VERSION

2.2

=cut

our $VERSION = 2.2;

=head1 SYNOPSIS

You can also subclass XML::RSS::Headline to tweak the rss content to your 
liking.  In this example. I change the headline to remove the date/time 
and add the Use Perl Journal author's ID.  Also in this use Perl; rss 
feed you get the actual link to the journal entry, rather than the link 
just to the user's journal.  (meaning that the journal URLs contain 
the entry's ID)

    use XML::RSS::Feed;
    use XML::RSS::Headline::UsePerlJournals;
    use LWP::Simple qw(get);

    my $feed = XML::RSS::Feed->new(
	name  => "useperljournals",
	hlobj => "XML::RSS::Headline::UsePerlJournals",
	delay => 60,
	url   => "http://use.perl.org/search.pl?tid=&query=&" 
                 . "author=&op=journals&content_type=rss",
    );

    while (1) {
	$feed->parse(get($feed->url));
	print $_->headline . "\n" for $feed->late_breaking_news;
	sleep($feed->delay); 
    }

Here is the output from rssbot on irc.perl.org in channel #news (which uses
these modules)

    <rssbot>  + [pudge] New Cool Journal RSS Feeds at use Perl;

=head1 MUTAITED METHOD

=head2 $headline->item( $item )

Init the object for a parsed RSS item returned by L<XML::RSS>.

=cut 

sub item {
    my ( $self, $item ) = @_;
    $self->SUPER::item($item);    # set url and description

    my $headline = $self->headline;
    my $url      = $self->url;
    my ($id) = $url =~ /\/\~(.+?)\//;
    $headline =~ s/\s+\(.+\)\s*$//;

    $self->headline("[$id] $headline");
}
