<a href="http://d.hatena.ne.jp/sirocco634/20100912#1284300126" onclick="__gaTracker('send', 'event', 'outbound-article', 'http://d.hatena.ne.jp/sirocco634/20100912#1284300126', '前回');" target="_blank">前回</a>までのところでは、「なんかリストを作るのが面倒くさいなぁ」と思ったのだが、よく考えたら quasi-quote を使えば問題ないことに気づく。こんな感じ:
</p>

<pre class="syntax-highlight">
<span class="synSpecial">(</span>use sxml.serializer<span class="synSpecial">)</span>
<span class="synSpecial">(</span>define gen-rss
<span class="synPreProc">`(</span><span class="synType">*TOP*</span>
<span class="synSpecial">(</span><span class="synType">*PI*</span> xml <span class="synConstant">&#34;version=\&#34;1.0\&#34; encoding=\&#34;UTF-8\&#34;&#34;</span><span class="synSpecial">)</span>
<span class="synSpecial">(</span>rss <span class="synSpecial">(</span>@ <span class="synSpecial">(</span>version <span class="synConstant">&#34;2.0&#34;</span><span class="synSpecial">))</span>
,channel-example<span class="synSpecial">)</span><span class="synPreProc">)</span><span class="synSpecial">)</span>
<span class="synSpecial">(</span>define channel-example
<span class="synPreProc">`(</span>channel
<span class="synSpecial">(</span>title <span class="synConstant">&#34;foobar&#34;</span><span class="synSpecial">)</span>
<span class="synSpecial">(</span>link <span class="synConstant">&#34;http://kazu634.tumblr.com/&#34;</span><span class="synSpecial">)</span>
<span class="synSpecial">(</span>description <span class="synConstant">&#34;Tumblr&#34;</span><span class="synSpecial">)</span>
<span class="synSpecial">(</span>lastBuildDate <span class="synConstant">&#34;Fri, 20 Jul 2007 19:00:00 +0900&#34;</span><span class="synSpecial">)</span>
,items-example<span class="synPreProc">)</span><span class="synSpecial">)</span>
<span class="synSpecial">(</span>define items-example
<span class="synPreProc">`(</span>item <span class="synSpecial">(</span>title <span class="synConstant">&#34;Post01&#34;</span><span class="synSpecial">)</span>
<span class="synSpecial">(</span>link <span class="synConstant">&#34;http://kazu634.tumblr.com/01&#34;</span><span class="synSpecial">)</span>
<span class="synSpecial">(</span>pubDate <span class="synConstant">&#34;Fri, 20 Jul 2007 19:00:00 +0900&#34;</span><span class="synSpecial">)</span><span class="synPreProc">)</span><span class="synSpecial">)</span>
</pre>

<p>
    実行例はこんな感じになる:
</p>

<pre class="syntax-highlight">
gosh&#62;<span class="synSpecial">(</span><span class="synStatement">print</span> <span class="synSpecial">(</span>srl:sxml-&#62;xml gen-rss<span class="synSpecial">))</span>

&#60;rss version=<span class="synConstant">&#34;2.0&#34;</span><span class="synStatement">&#62;</span>
&#60;channel&#62;
&#60;title&#62;foobar&#60;/title&#62;
&#60;link&#62;http://kazu<span class="synConstant">634.</span>tumblr.com/&#60;/link&#62;
&#60;description&#62;Tumblr&#60;/description&#62;
&#60;lastBuildDate&#62;Fri, <span class="synConstant">20</span> Jul <span class="synConstant">2007</span> <span class="synConstant">19</span>:<span class="synConstant">00</span>:<span class="synConstant">00</span> +<span class="synConstant">0900</span>&#60;/lastBuildDate&#62;
&#60;item&#62;
&#60;title&#62;Post<span class="synConstant">01</span>&#60;/title&#62;
&#60;link&#62;http://kazu<span class="synConstant">634.</span>tumblr.com/<span class="synConstant">01</span>&#60;/link&#62;
&#60;pubDate&#62;Fri, <span class="synConstant">20</span> Jul <span class="synConstant">2007</span> <span class="synConstant">19</span>:<span class="synConstant">00</span>:<span class="synConstant">00</span> +<span class="synConstant">0900</span>&#60;/pubDate&#62;
&#60;/item&#62;
&#60;/channel&#62;
&#60;/rss&#62;
#&#60;undef&#62;
</pre>

<p>
    なんだ簡単そうだぞ。
