<?php
// Create a function that will turn an RSS feed, into a definition list:
function rss_dl($url) {
    // Begin by loading the RSS feed into SimpleXML:
    $rss = simplexml_load_file($url);
    
    // Ok, output the title of the feed just as a paragraph block.  People
    //  can use stylesheets later to make it look as they wish:
    echo <<<EOSNIPPET
<p>
  <a href="{$rss->channel->link}">{$rss->channel->title}</a>
</p>
EOSNIPPET;
    
    // Now begin our definition list:
    echo "<dl>\n";
    
    // Loop through all items to make definition entries from them
    foreach ($rss->channel->item as $i) {
        // The title with link:
        echo "<dt><a href=\"{$i->link}\">{$i->title}</a></dt>\n";

        // The description as the dd
        echo "<dd>{$i->description}</dd>\n";        
    }
    
    // End our list now, we are done
    echo "</dl>\n";
}

// Test this out:
rss_dl('http://acorn.atlantia.sca.org/calendar.xml');

// And try it again:
echo "<br /><br /><br />\n";
rss_dl('http://rss.cnn.com/rss/cnn_topstories.rss');
