c#如何解析html获得div中的内容

如：<div id="title"><div id="xx">这是内容</div></div>
<div class="title">
<a class="title" href="http://www.amazon.com/Adventures-Sherlock-Holmes-Oxford/dp/0192123181/ref=sr_1_1?s=books&ie=UTF8&qid=1286845217&sr=1-1">The Adventures of Sherlock Holmes (The Oxford Sherlock Holmes)</a>
<span class="ptBrand">by <a href="/Sir-Arthur-Conan-Doyle/e/B000AQ43GQ/ref=sr_ntt_srch_lnk_1?qid=1286845217&sr=1-1">Sir Arthur Conan Doyle</a> and Richard Lancelyn Green</span>
<span class="bindingAndRelease">(<span class="binding">Hardcover</span> - Oct 28, 1993)</span>
</div>

要获得第一个a标签的内容：href="http://www.amazon.com/Adventures-Sherlock-Holmes-Oxford/dp/0192123181/ref=sr_1_1?s=books&ie=UTF8&qid=1286845217&sr=1-1">
