Delete Items in object of Zend_Feed

Hi,

I am trying to manipulate a feed and filter items out, if the title contains certain text. But I don't know how to "unset" a item.

So here is how I try to do it.

After creating the feed just like in the example:

PHP Code:


			
$strFeed = ''http://rss.mylinktosuperfeed";

// get the feed
try {
    $spxRss = Zend_Feed::import($strFeed);
} catch (Zend_Feed_Exception $e) {
    // Import des Feeds ist fehlgeschlagen
    echo "Exception caught importing feed: {$e->getMessage()}\n";
    exit;
}

I try to iterate through the feed and check for the title and if it is matching my word it should be deleted in the feed

PHP Code:


			
foreach ($spxRss as $item) {
    if ( strpos(strtolower($item->title()), 'stringIdontWant') !== FALSE ) { 
         $spxRss->offsetUnset($spxRss->key());
    }
}
echo $spxRss->saveXML();

I get the right key of the Item I want to delete in the feed, but it is not deleting it.

I'm probably doing this totally wrong.....can someone please help me?
