What is RSS Feed?

What exactly is an RSS feed and how can someone integrate an RSS feed from one site to the next? Is there anyone out there that can explain this as easy as possible. Im very much interested in how this thing works.

I here so much about it, and people saying they have rss on there site ( i know what it does ) I just dont know how its created and how to make it function on other sites.

RSS feed just feeds information from one site to the next. Any text or images from one site will get updated auto. on the site with the RSS feed on it. I understand that whole process but would like it if someone could break it down a little more for me if thats possible

Thanks,
- Jerome

RSS = XML file, which consists your RSS news in certain format

This is an example of RSS [xml] file in 1.0 standart (RSS 1.0)
Code:
<?xml version="1.0"?>

It is fairly easy to create an RSS feed if you are using a CMS like Wordpress, Textpattern or anything else, in fact they create one automatically. However, if you don't use a CMS it is a bit harder to create an RSS feed because you must know how to code one.

If you could be a little bit more specific in what you want to know maybe i could help you a bit more.

Have a look at www.simplepie.org. My friend uses it for his site: www.ntugo.com. I haven't used it myself but I think what it does is it gets the RSS feed URL and displays the RSS feed on a page of your choice.

http://feedburner.com is a great tool for managing your rss feeds.

RSS is a standard for distribute news in internet.

It's based in XML with its own structure.

hI gUYS...can we make rss web with cms like Joomla or Mambo ?? because i am learning that cms right now..?
SlowWalkere
There are probably some good pre-made extensions you could use for Joomla or Mambo to create a feed for your site. The Joomla! Extension Directory shows 34 results for RSS Feeds. Not sure how good they are... but I'm sure there's something in there that works.

If you're up to coding your own extension, it's pretty easy to make a php script to pull information out of your database and create an RSS feed on the fly.

I'm working on a project in CMS Made Simple and wrote this short script to dynamically create a feed. CMSMS uses Smarty templates to render content, so the script comes in two parts...

Here's a link to the generated feed: Recent Lesson Plans (note the site is still in dev, so there's not a lot of content there).

The xml template is for a barebones feed with all the necessary info. Write a script to pull the relevant information out of your database, put it into a template like the one below, and you should be good to go.

The PHP script that generates the feed:
Code:
      $artArray = array();
      
      $query = "SELECT * FROM " . cms_db_prefix() . "module_articles LIMIT 0,10";
      
      $result = $db->Execute($query);
      
      while ($row = $result->FetchRow())
      {
         $onerow = new stdClass();
         
         // Set up the basic article information in the array
         $onerow->id = $row['article_id'];
         $onerow->title = $row['article_title'];
         $onerow->description = $row['description'];
         $onerow->morelink = $this->CreateFrontEndLink($id, $returnid, 'viewarticle', 'Read the Entire Article',
                                            array($onerow->$id), '', true, true, '', false, 'viewarticle/'
                                            . $onerow->id . '/' . $this->getReturnid('view'));
         
         $artArray[] = $onerow;
      }

   $this->smarty->assign('feed_title', 'Babel - Recent Lesson Plans');
   $this->smarty->assign('feed_desc', 'This feed contains recent lesson plans submitted by users at Babel.  Browse the catalog, then
                     submit some lesson plans of your own!');
   $this->smarty->assign('page_link', 'http://walkere.frih.net/teach/');
   $this->smarty->assign('feed_link', 'http://walkere.frih.net/teach/feeds/plans-feed.xml');
   
   $smarty->assign_by_ref('items', $artArray);
   $smarty->assign('itemcount', count($artArray));
   
   echo $this->ProcessTemplate('feed.tpl');


That gets sent to the template:
Code:
<?xml version='1.0'?>

<rss version='2.0' xmlns:atom='http://www.w3.org/2005/Atom'>

<channel>

   <title>{$feed_title}</title>
   <atom:link href='{$feed_link}' rel='self' type='application/rss+xml' />
   <link>{$page_link}</link>
   <description>{$feed_desc}</description>

   {foreach from=$items item=record}
   <item>
      <guid>{$record->morelink}</guid>
      <title>{$record->title}</title>
      <link>{$record->morelink}</link>
      <description>{$record->description}</description>
   </item>
   {/foreach}
</channel>

</rss>
