我有一个来自服务器的数据列表，我想要的是用span仅替换class="more-info"，而这些<div class="col-md-12">
<ul class="performance-list list-unstyled">
<li>
<div class="date">
<span class="month-date-year">13. Sep, 2018</span>
<span class="weekday">xxx</span>
</div>
<div class="name">
<h3>xx xx</h3>
<span class="name2">xx xxx xxx. xxx</span>
<span class="more-info">20:00 Uhr / xxxxxx</span>
</div>
<div class="action">
<a href="/xxx" class="btn btn-default">Tickets</a>
</div>
</li>
<li>
<div class="date">
<span class="month-date-year">23. Sep, 2018</span>
<span class="weekday">xxx</span>
</div>
<div class="name">
<h3>xx xx xx xxx</h3>
<span class="name2">xx xxx</span>
<span class="more-info">, </span>
</div>
<div class="action">
<a href="xxx" class="btn btn-default">Tickets</a>
</div>
</li>
</ul>
</div>
仅以“，”作为其数据，并将其保留为空。只有CSS才有可能吗？
