<p><strong class="program">Universal Feed Parser</strong> can parse many different types of feeds: Atom,
<abbr title="Channel Definition Format">CDF</abbr>, and nine different versions of
<abbr title="Rich Site Summary">RSS</abbr>. You should not be forced to learn the
differences between these formats. <strong class="program">Universal Feed Parser</strong> does its
best to ensure that you can treat all feeds the same way, regardless of format
or version.</p>
<p>You can access the basic elements of an Atom feed using <abbr title="Rich Site Summary">RSS</abbr> terminology.</p>
