migrate google reader listen subscriptions to subsonic server

opml_to_subsonic.php

<?php
$subsonic_url = "192.168.0.101:4040";
$subsonic_user = "myuser";
$subsonic_pass = "mypass";

#Create xml object from subscriptions.xml opml file 
$xml = new SimpleXMLElement(file_get_contents('subscriptions.xml'));

#Narrow feed items to just those for Google Listen with xpath
$listen = $xml->xpath('//outline[@title="Listen Subscriptions"]');
$listen_outline = $listen[0]->outline;

#Log into local subsonic server with username and password, store cookies in cookies.txt
echo `curl -L -c cookies.txt -d 'j_username=$subsonic_user&j_password=$subsonic_pass&_acegi_security_remember_me=1' http://$subsonic_url/j_acegi_security_check\n`;

#Send a curl request to subsonic server to add each feed item
foreach($listen_outline as $elem) {
  $url = urlencode($elem['xmlUrl']);
  echo `curl -L -b cookies.txt -d 'add=$url' 'http://$subsonic_url/podcastReceiverAdmin.view?'\n`;
}

#Maybe should remove cookies.txt file?
?>

I exported my Google Listen subscriptions from google reader to the file subscriptions.xml
I put this gist in the same directory
On the command line, ran:
php opml_to_subsonic.php

confirmed that subsonic now had my subscriptions
