NAME
MagpieRSS - a simple RSS integration tool
SYNOPSIS
require_once(rss_fetch.inc);
$url = $_GET['url'];
$rss = fetch_rss( $url );
echo "Channel Title: " . $rss->channel['title'] . "<p>";
echo "<ul>";
foreach ($rss->items as $item) {
$href = $item['link'];
$title = $item['title'];
echo "<li><a href=$href>$title</a></li>";
}
echo "</ul>";
DESCRIPTION
MapieRSS is an XML-based RSS parser in PHP. It attempts to be "PHP-like",
and simple to use.
Some features include:
* supports RSS 0.9 - 1.0, with limited RSS 2.0 support
* supports namespaces, and modules, including mod_content and mod_event
* open minded [1]
* simple, functional interface, to object oriented backend parser
* automatic caching of parsed RSS objects makes its easy to integrate
* supports conditional GET with Last-Modified, and ETag
* uses constants for easy override of default behaviour
* heavily commented
1. By open minded I mean Magpie will accept any tag it finds in good faith that
it was supposed to be here. For strict validation, look elsewhere.

If caching is on (MAGPIE_CACHE_ON) fetch_rss will first check the cache.

return a cached object, and touch the cache object upon recieving a
