[RESOLVED] simpleXML and Namespaces Help

[abovethefold]

I have a feed that has been working fine till I modified the feed to support iTunes, which uses namespaces. I am trying to get the information from the feed to display, but I am not having luck.

Here's a snippet of the feed:

<?xml version="1.0"?>
<rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0">
<channel>
<title>Company Podcasts</title>

function processFeed($rss,$type) {

# Initiate variables

}

}
}
}
foreach ($itunes as $item) {
for ($i = 0; $i < 50; $i++) {

foreach ($item[$i]->author as $author) {
$_GET['newsoutput'] .= "$author</li>";
}

}
}
break;
# End case "sermons"

case "home":

foreach ($xml->channel->item as $item) {
for ($i = 0; $i < 2; $i++) {

foreach ($item[$i]->pubDate as $date) {
$date = substr($date, 0, -15);
$_GET['newsoutput'] .= "<li><strong>$date</strong><br />";
}

}
foreach ($item[$i]->title as $title) {

}
}
}
break;
# End case "home"

} # End Switch

$_GET['newsoutput'] .= "</ul>";
echo $_GET['newsoutput'];
}

and the call is:

<?php processFeed("http://localhost/podcast.xml","sermons"); ?>
