One Handy Loop
This one loop will most probably change the most useful pieace of code i can recommend of.
This would pull an rss of your choice and list the number an item you choose.
(the list markup seems the reasonable one to use but this up to your needs)
<ul>
<?php // Get RSS Feed(s)
include_once(ABSPATH . WPINC . '/rss.php');
$rss = fetch_rss("[YOUR FEED HERE]");
$maxitems = [YOUR NUM OF ITEMS];
$items = array_slice($rss->items, 0, $maxitems);
?>
<ul>
<?php if (empty($items)) echo '<li>No items</li>';
else
foreach ( $items as $item ) : ?>
<li><a href='<?php echo $item['link']; ?>'
title='<?php echo $item['title']; ?>'>
<?php echo $item['title']; ?>
</a></li>
<?php endforeach; ?>
</ul>
