Please refer to 'Google Feeds AJAX API' documentation for complete list of arguments for Google Feeds service. E.g.: my $res = REST::Google::Feeds->new( q => 'http://digg.com/rss/index.xml', ); The code above will perform a following HTTP GET request: http://ajax.googleapis.com/ajax/services/feed/load?q=http%3A%2F%2Fdigg.com%2Frss%2Findex.xml&v=1.0 I<Note:> You can left protocol version number unspecified while making your searches since C<v=1.0> is passed by default. See L<REST::Google> C<new> method. =item responseData Method returns C<REST::Google::Feeds::Data> object, which has a single method C<feed>. my $res = REST::Google::Feeds->new( q => 'http://digg.com/rss/index.xml', ); my $feed = $res->responseData->feed; =item feed Method returns C<REST::Google::Feeds::Feed> object, which has accessors for all incapsulated data. my $feed = $res->responseData->feed; print $feed->title; print $feed->link; Attributes of C<$feed> are: title link author description type entries Obtaining feed entries: foreach my $entry ($feed->entries) { print $entry->title; } Attributes of C<$entry> are: title link author publishedDate contentSnippet content categories =back =head1 SEE ALSO L<REST::Google> - the base class for this module L<http://code.google.com/apis/ajaxfeeds/documentation/#fonje> - Google Feeds AJAX API =head1 LICENSE AND COPYRIGHT Copyright 2008, Eugen Sobchenko <ejs@cpan.org> and Sergey Sinkovskiy <glorybox@cpan.org> This program is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
