            var feed = feedCreator.create({
                title: 'mysite',
                description: 'RSS akışı',
                url: 'http://www.mysite.com/feed/'
            });

            _.each(juices, function (juice) {
                feed.item({
                    title: juice.name,
                    description: juice.descripton,
                    url: util.format('http://www.mysite.com/likit/'),
                    date: juice.createdAt
                });
            });

            res.send(feed.xml());

output;
