<?php the_tags( \'<ul><li>\', \'</li><li>\', \'</li></ul>\' ); ?> 

当我们使用上述内容时，我们会得到这种HTML→

<ul>
<li><a href="http://......./tag/first-lady/" rel="tag">first lady</a></li>
<li><a href="http://........./tag/ivanka/" rel="tag">ivanka</a></li>
<li><a href="http://......../tag/sexy/" rel="tag">sexy</a></li>
</ul>  

有没有可能在锚标记中插入这样的类→

<li><a href="http://........./tag/ivanka/" rel="tag" class="my_custom_class">ivanka</a></li>
