get_channel_tags()

class SimplePie {
	get_channel_tags ( string $namespace, string $tag )
}

This method allows you to get access to ANY element/attribute in the channel/header section of the feed. It will return an array, which you should look at with PHP's print_r() function.

Note that this will return an array of all of the elements it finds, and you can only go deeper – not shallower.

• Available since SimplePie 1.0.

The URL of the XML namespace of the elements you're trying to access. SimplePie has a number of constants for supported namespaces in our Supported XML Namespaces document. If we don't have a constant for it, you can manually add the namespace URL as listed inside the feed.

This is the tag (element) that you want to get.

$feed = new SimplePie();
$feed->set_feed_url('http://video.google.com/videofeed?type=top100new&num=20&output=rss');
$feed->enable_cache(false);
$success = $feed->init();
$feed->handle_content_type('text/plain');
 
if ($success)
{
	$opensearch = $feed->get_channel_tags('http://a9.com/-/spec/opensearchrss/1.0/', 'itemsPerPage');
	echo $opensearch[0]['data'];
}
else
{
	echo $feed->error();
}
