PHP SimplePie::get_feed_tagsの例

get_feed_tags() public method

This method allows you to get access to ANY element/attribute that is a sub-element of the opening feed tag. The return value is an indexed array of elements matching the given namespace and tag name. Each element has attribs, data and child subkeys. For attribs and child, these contain namespace subkeys. attribs then has one level of associative name => value data (where value is a string) after the namespace. child has tag-indexed keys after the namespace, each member of which is an indexed array matching this same format. For example:

This is probably a bad example because we already support
 natively, but it shows you how to parse through
the nodes.
$group = $item->get_item_tags(SIMPLEPIE_NAMESPACE_MEDIARSS, 'group');
$content = $group[0]['child'][SIMPLEPIE_NAMESPACE_MEDIARSS]['content'];
$file = $content[0]['attribs']['']['url'];
echo $file;

Since: 1.0

public get_feed_tags ( string $namespace, string $tag ) : array
$namespace	string	The URL of the XML namespace of the elements you're trying to access
$tag	string	Tag name
return	array

 * $datedir sorts in reverse order
 *
 * @param array $xml
 *   The (atom) feed to consume - RSS isn't as fully supported but may work for simple feeds.
 * @param $importer
 *   The contact_record (joined to user_record) of the local user who owns this
 *   relationship. It is this person's stuff that is going to be updated.
 * @param $contact
 *   The person who is sending us stuff. If not set, we MAY be processing a "follow" activity
 *   from an external network and MAY create an appropriate contact record. Otherwise, we MUST
 *   have a contact record.
 * @param int $pass by default ($pass = 0) we cannot guarantee that a parent item has been
 *   imported prior to its children being seen in the stream unless we are certain
 *   of how the feed is arranged/ordered.
 *  * With $pass = 1, we only pull parent items out of the stream.
 *  * With $pass = 2, we only pull children (comments/likes).
 *
 * So running this twice, first with pass 1 and then with pass 2 will do the right
 * thing regardless of feed ordering. This won't be adequate in a fully-threaded
 * model where comments can have sub-threads. That would require some massive sorting
 * to get all the feed items into a mostly linear ordering, and might still require
 * recursion.
