how do i get the content for the last rss feed

I have this feed and i just need to parse out the latest rss feed. I basically want to know if i can get the information for the latest one...I have this code that helps parse all the rss feeds but how do i just get the latest

$validCache = false;
if (file_exists('rss_cache.txt')) {
    $contents = file_get_contents('rss_cache.txt');
    $data = unserialize($contents);
    if (time() - $data['created'] < 24 * 60 * 60) {
        $validCache = true;
        $feed = $data['feed'];
    }
}

if (!$validCache) {
    $feed = file_get_contents('http://someplace.com/feed/');
    $data = array ('feed' => $feed, 'time' => time());
    file_put_contents('rss_cache.txt', serialize($data));
}

EDIT: tried 

$xml = simplexml_load_file('http://blog.airdye.com/goodforwater/feed/');
print_r($xml->channel->item[0]);

but the description is blank
