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