change the way to parse title

youku 的HTML中包含了

		div class="guide">
    		<div class="crumbs">
                <a href="http://tv.youku.com/" target="_blank">电视剧</a>
    			<span class="arrow"> &gt; </span>
                                <a href="http://www.youku.com/v_olist/c_97_a_%E7%BE%8E%E5%9B%BD.html" target="_blank">美国</a><span class="arrow"> &gt; </span>                                <a href="http://www.youku.com/v_olist/c_97_g_%E5%89%A7%E6%83%85.html" target="_blank">剧情</a>/<a href="http://www.youku.com/v_olist/c_97_g_%E7%A7%91%E5%B9%BB.html" target="_blank">科幻</a>/<a href="http://www.youku.com/v_olist/c_97_g_%E6%82%AC%E7%96%91.html" target="_blank">悬疑</a>			</div>
		</div>
		<h1 class="title"><a charset="hz-4006554-1000595" href="http://www.youku.com/show_page/id_z3862ad4cbc5c11e2b2ac.html" target="_blank" title="沉睡谷">沉睡谷</a>：<span id="subtitle">第1集</span></h1>

从这里获取title 更准确一些
