Zend Framework

• Type: Bug
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Affects Version/s: 1.9.5
• Fix Version/s: 1.9.6
• Component/s: Zend_Feed_Reader
• Labels:

  None

Zend_Feed_Reader sucessfully imports non-feed documents (valid XHTML pages). I think it should throw an exception.

Code:

$feed = Zend_Feed_Reader::import('http://twitter.com/alganet');
echo $feed->getDomDocument()->documentElement->nodeName;

Output:

html

Expected:

Fatal error: Uncaught exception 'Zend_Feed_Exception' with message 'URL must point to a feed document' (...)

Workaround Sample:

$allowedMimetypes = array(
    'application/atom+xml',
    'application/rss+xml',
);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'http://twitter.com/alganet');
curl_setopt($curl, CURLOPT_HEADER, true); 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_NOBODY, true); //Just headers
$headers = explode("\n", curl_exec($curl));
foreach ($headers as $header) {
    $header = explode(":", $header);
    if (count($header) != 2) continue;
    if (strtolower($header[0]) == 'content-type') {
        $header[1] = trim($header[1]);
        if (!in_array($header[1], $allowedMimetypes)) {
            throw new Zend_Feed_Exception('URL must point to a feed document');
        } 
        break;
    }
}
curl_close($curl);
