Retrieving Feeds from Web Pages
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.
