RSS-PHP Example
Here's a simple solution to convert RSS to HTML using RSS-PHP and Smarty:
<?php
/* RSS_PHP */
require_once 'rss_php.php';
$rss = new rss_php;
$rss->load('http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml');
/* Smarty */
include 'Smarty.class.php';
$smarty = new Smarty;
$smarty->assign('rss', $rss->getItems());
$smarty->display('index.tpl');
/* expecting more ?? */
?>

RSS-PHP Dependencies
As RSS-PHP utilises the DOM to parse RSS, and the DOM Extension is installed as part of the PHP Core, RSS-PHP's only dependency is PHP 5.
RSS-PHP Internationalization and Character Encoding Support
RSS-PHP uses the UTF-8 Character Encoding by default, this is a dependency of PHP's DOM.
Use utf8_encode() and utf8_decode() to work with texts in ISO-8859-1 encoding or Iconv for other encodings.
