小编its*_*uta的帖子

我有以下标记:

<div id="breadcrumbs">
  <ul>
   <li><span class="crumblink"><a href="/">Home</a></span></li>
   <span class="arrows"> »</span>  
   <li><span class="crumblink"><a href="/locations-brands">Publishing Regions</a></span></li>
   <span class="arrows"> »</span>  
   <li><span class="crumblink"><a href="/locations-brands/publications">Locations &amp; Brands</a></span></li>
   <span class="arrows"> »</span>
   <li><span class="crumblink"><a href="/locations-brands/publications/popupbrand">Publications</a></span></li>
   <span class="arrows"> »</span>  
  </ul>
</div>

如何删除<li>if有字符串"Publications"及其下一个span.arrows？
