This script adds the "folder" child based off the show name so the shanaproject.com YaRSS Deluge Plugin can auto sort your shows off ShowRSS -- This PHP file is called like getfeed.php?id=43302 - so if your old feed url is http://showrss.info/user/43302.rss

getfeed.php

<?php
header("Content-type: text/xml");
//setup globals
$dataurl = "http://showrss.info/user/" . preg_replace("/[^0-9]/", "",$_GET['id']) . ".rss";
$data = file_get_contents($dataurl);

$xml = new SimpleXMLElement($data);
foreach($xml->channel->item as $item){
$namespaces = $xml->getNameSpaces(true);
$tv = $item->children($namespaces['tv']);
$name = $tv->show_name;
$item->folder = $name . "/";
}
echo $xml->asXML();
