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 & 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 具有字符串“Publications”及其下一个span.arrows
?
