Html 如何使用xpath从div获取href值？

我有一个这样的部门：

    <div class="widget-archive-monthly widget-archive widget"> 
    <h3 class="widget-header">Monthly <a href="http://myblog.com/blogs/my_name/archives.html">Archives</a></h3> 
    <div class="widget-content"> 
        <ul> 
            <li><a href="http://myblog.com/blogs/my_name/2010/10/">October 2010</a></li>
