<h2>Building</h2>
<p>Building entries and feeds is simple:</p>
<pre><code>#!ruby
require "atom/feed"
e = Atom::Entry.new
e.title = "a new entry"
e.content = "some <em>boring</em> HTML"
e.content.type = "html"
e.categories.new :term => "Test Entry"
feed = Atom::Feed.new
feed << e
feed.to_s
# => "<feed xmlns='http://www.w3.org/2005/Atom'><entry><title>a new entry</title><content type='html'>some &lt;em&gt;boring&lt;/em&gt; HTML</content><category term='Test Entry'/></entry></feed>"
</code></pre>
<p>atom-tools won’t complain if you’ve forgotten to include all the bits you need, so you should run the final product through <a href="http://feedvalidator.org/">the Feed Validator</a> before you publish.</p>
<h2>Parsing</h2>
<pre><code>#!ruby
require "atom/feed"
f = Atom::Feed.new("http://www.tbray.org/ongoing/ongoing.atom")
f.entries
# => []
f.update!
f.entries
# => [#<Atom::Entry>, ...]
f.entries.first.title.to_s
# => "Tag Scheme?"
</code></pre>
<h2>More Complex Things</h2>
<ul>
<li><a href="http://github.com/sr">Simon Rozet</a> has written several simple Atom Publishing Protocol servers</li>
<li>atom-tools/bin/atom-cp — an Atom Publishing Protocol client that can copy entries from one feed to another</li>
<li>[[VoxApi]] — faking the Atom <span class="caps">API</span></li>
<li>[[HtmlToXhtml]] — convert @type=‘html’ to @type=‘xhtml’</li>
</ul>
