<p><a href="../RSS.html"><code>RSS</code></a> has three different versions. This module contains support for version <a href="http://www.rssboard.org/rss-0-9-1-netscape">0.9.1</a>.</p>

<p>Producing our own <a href="../RSS.html"><code>RSS</code></a> feeds is easy as well. Let's make a very basic feed:</p>
<pre class="ruby"><span class="ruby-identifier">require</span> <span class="ruby-string">"rss"</span>
<span class="ruby-identifier">rss</span> = <span class="ruby-constant">RSS</span><span class="ruby-operator">::</span><span class="ruby-constant">Maker</span>.<span class="ruby-identifier">make</span>(<span class="ruby-string">"0.91"</span>) <span class="ruby-keyword">do</span> <span class="ruby-operator">|</span><span class="ruby-identifier">maker</span><span class="ruby-operator">|</span>

<span class="ruby-identifier">maker</span>.<span class="ruby-identifier">channel</span>.<span class="ruby-identifier">updated</span> = <span class="ruby-constant">Time</span>.<span class="ruby-identifier">now</span>.<span class="ruby-identifier">to_s</span>
<span class="ruby-identifier">maker</span>.<span class="ruby-identifier">channel</span>.<span class="ruby-identifier">link</span> = <span class="ruby-string">"http://www.ruby-lang.org/en/feeds/news.rss"</span>
<span class="ruby-identifier">maker</span>.<span class="ruby-identifier">channel</span>.<span class="ruby-identifier">title</span> = <span class="ruby-string">"Example Feed"</span>
<span class="ruby-identifier">maker</span>.<span class="ruby-identifier">channel</span>.<span class="ruby-identifier">description</span> = <span class="ruby-string">"A longer description of my feed."</span>
<span class="ruby-identifier">maker</span>.<span class="ruby-identifier">image</span>.<span class="ruby-identifier">url</span> = <span class="ruby-string">"http://www.ruby-lang.org/images/logo.gif"</span>
<span class="ruby-identifier">maker</span>.<span class="ruby-identifier">image</span>.<span class="ruby-identifier">title</span> = <span class="ruby-string">"An image"</span>
<span class="ruby-identifier">maker</span>.<span class="ruby-identifier">items</span>.<span class="ruby-identifier">new_item</span> <span class="ruby-keyword">do</span> <span class="ruby-operator">|</span><span class="ruby-identifier">item</span><span class="ruby-operator">|</span>
<span class="ruby-identifier">item</span>.<span class="ruby-identifier">link</span> = <span class="ruby-string">"http://www.ruby-lang.org/en/news/2010/12/25/ruby-1-9-2-p136-is-released/"</span>
<span class="ruby-identifier">item</span>.<span class="ruby-identifier">title</span> = <span class="ruby-string">"Ruby 1.9.2-p136 is released"</span>
<span class="ruby-identifier">item</span>.<span class="ruby-identifier">updated</span> = <span class="ruby-constant">Time</span>.<span class="ruby-identifier">now</span>.<span class="ruby-identifier">to_s</span>
<span class="ruby-keyword">end</span>
<span class="ruby-keyword">end</span>
<span class="ruby-identifier">puts</span> <span class="ruby-identifier">rss</span>
</pre>
<p>As you can see, this is a very Builder-like DSL. This code will spit out an <a href="../RSS.html"><code>RSS</code></a> 0.9 feed with one item. If we needed a second item, we'd make another block with maker.items.new_item and build a second one.</p>
