Web pages often contain <link>
tags that refer to feeds with content
relevant to the particular page. Zend_Feed
enables you to retrieve
all feeds referenced by a web page with one simple method call:
$feedArray = Zend_Feed::findFeeds('http://www.example.com/news.html');
Here the findFeeds()
method returns an array of
Zend_Feed_Abstract
objects that are referenced by
<link>
tags on the news.html web page. Depending on the type of each
feed, each respective entry in the $feedArray
array may be a
Zend_Feed_Rss
or Zend_Feed_Atom
instance.
Zend_Feed
will throw a Zend_Feed_Exception
upon failure, such as an HTTP 404 response code or a malformed feed.
