Finally, you can extend the Zend_Feed classes if you'd like to
provide your own format or niceties like automatic handling of elements that should go into
a custom namespace.
Here is an example of a custom Atom entry class that handles its own myns: namespace entries. Note that it also makes the registerNamespace() call for you, so the end user doesn't need to worry about namespaces at all.
Example #1 Extending the Atom Entry Class with Custom Namespaces
/**
* The custom entry class automatically knows the feed URI (optional) and
* can automatically add extra namespaces.
*/
class MyEntry extends Zend_Feed_Entry_Atom
{
public function __construct($uri = 'http://www.example.com/myfeed/',
$xml = null)
{
parent::__construct($uri, $xml);
Zend_Feed::registerNamespace('myns',
'http://www.example.com/myns/1.0');
}
public function __get($var)
{
switch ($var) {
case 'myUpdated':
// Translate myUpdated to myns:updated.
return parent::__get('myns:updated');
default:
return parent::__get($var);
}
}
public function __set($var, $value)
{
switch ($var) {
case 'myUpdated':
// Translate myUpdated to myns:updated.
parent::__set('myns:updated', $value);
break;
default:
parent::__set($var, $value);
}
}
public function __call($var, $unused)
{
switch ($var) {
case 'myUpdated':
// Translate myUpdated to myns:updated.
return parent::__call('myns:updated', $unused);
default:
return parent::__call($var, $unused);
}
}
}
Then to use this class, you'd just instantiate it directly and set the myUpdated property:
$entry = new MyEntry(); $entry->myUpdated = '2005-04-19T15:30'; // method-style call is handled by __call function $entry->myUpdated(); // property-style call is handled by __get function $entry->myUpdated;
