在Code Igniter中创建RSS提要

我正试图将本教程与我为它发布的新闻故事相匹配，但在某个地方有些东西不工作，我不太确定在哪里。

http://net.tutsplus.com/tutorials/php/building-an-rss-2-0-feed-with-codeigniter/

我已经自动加载了文本和xml帮助程序。

模型:

<?php
class Newsfeedmodel extends CI_Model {
function __construct()
{
    // Call the Model constructor
    parent::__construct();
} 
// get all postings  
function getPosts($limit = NULL)  
{  
    $this->db->select('site_news_articles.article_title, site_news_articles.permalink, site_news_articles.date_published');
    $this->db->from('site_news_articles'); 
    $this->db->where('site_news_articles.is_approved', 'Yes');
    $this->db->where('site_news_articles.status_id', 1);
    $this->db->order_by('site_news_articles.date_published', 'desc');  
    $this->db->limit($limit);
    $query = $this->db->get();
    return $query->result_array(); 
}   
}
?>

视图:

    <!--?php  echo '<?xml version="1.0" encoding="' . $encoding . '"?-->' . "'n"; ?>
<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" xmlns:admin="http://webns.net/mvcb/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:content="http://purl.org/rss/1.0/modules/content/">
    <channel>
<link><!--?php echo $feed_url; ?-->
    <description><!--?php echo $page_description; ?--></description>
    <dc:language><!--?php echo $page_language; ?--></dc:language>

    <admin:generatoragent rdf:resource="http://www.codeigniter.com/">
    <!--?php foreach($posts--->result() as $post): ?>
        <item>
 <link><!--?php echo site_url('blog/posting/' . $post--->id) ?>
          <guid><!--?php echo site_url('blog/posting/' . $post--->id) ?></guid>
            <description><!--[CDATA[ <?php echo character_limiter($post--->text, 200); ?> ]]></description>
 <pubdate><!--?php echo $post--->date; ?></pubdate>
        </item>
    <!--?php endforeach; ?-->
    </admin:generatoragent></channel>
</rss>

控制器:

<?php 
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Newsfeed extends CI_Controller
{
function Feed()  
{  
    parent::__construct();
    $this->load->model('newsfeedmodel', 'posts');
}  
function index()
{
    /**********************************************************Your Coding Logic Here, Start*/

    $data['feed_name'] = 'Kansas Outlaw Wrestling, LLC.'; // your website  
    $data['encoding'] = 'utf-8'; // the encoding  
    $data['feed_url'] = 'http://www.kansasoutlawwrestling.com/newsfeed'; // the url to your feed  
    $data['page_description'] = 'True Outlaws of the Midwest'; // some description  
    $data['page_language'] = 'en-en'; // the language  
    $data['creator_email'] = 'kowmanagement@kansasoutlawwrestling.com'; // your email  
    $data['posts'] = $this->posts->getPosts(10);  
    $this->output->set_header("Content-Type: application/rss+xml"); // important! 
    $this->load->view('rss', $data);  
    /***********************************************************Your Coding Logic Here, End*/
}
}
/* End of file newsfeed.php */
/* Location: ./application/controllers/newsfeed.php */

编辑:

使用上面的代码，我得到这个错误:

Parse error: syntax error, unexpected T_STRING in /home/xtremer/public_html/application/views/rss.php on line 1

<!--?php  echo '<?xml version="1.0" encoding="' . $encoding . '"?-->' . "'n"; ?>

<?php  echo '<?xml version="1.0" encoding="' . $encoding . '"?>' . "'n"; ?>
