Witam

Mam problem z Zend_Cache_File. Chcialem zrobić cache pliku xml na tej zasadzie ze kiedy zostanie zmodyfikowany masterFile to cache zostanie usuniete i utworzone nowe.
Mam taki kod:

[PHP] pobierz, plaintext 
<?php
$controller = $this->request->getControllerName();
$file = $this->config->auth->path . $controller . '.xml';
$frontendOptions	= array('masterFile' => $file, 'automaticSerialization' => true);
$backendOptions	= array('cacheDir' => $this->config->cache_dir);
$cache		= Zend_Cache::factory('File', 'File', $frontendOptions, $backendOptions);
 
	if (!($xml = $cache->load($controller)))
	{
		$xml = simplexml_load_file($file);
		$cache->save($xml);
	}
?>
[PHP] pobierz, plaintext 

Xml jest serializowny do cache i cały czas php pluje błędami:
Warning: unserialize() [function.unserialize]: Node no longer exists in Zend\Cache\Core.php on line 222

Z tego co wyczytałem, to nie mozna unserializowac obiektów simplexml. Sam sie mecze z tym i nie da rady ;/
