javascript - 对 Node 中的字母数字 li 进行排序

Question

从 html 页面，我可以通过 querySelectorAll. 获取 Node 列表之后，通过一个循环，我得到了我需要工作的 Node :

给定具有以下格式的 Node 列表的 Node :

<div id="search_filters">
 <section class="facet clearfix">
   <p>something3</p>
   <ul>
     <li>text1 abc-def 200-201<span>(35)</span></li>
     <li>text2 hjk-lef 203 <span>(11)</span></li>
     <li>text3 fgh 204 <span>(250)</span></li>
     <li>text4 sfsa 205 <span>(100)</span></li>
   </ul>
  </section>
</div>

我正在尝试对 <li> 进行排序以 desc 数字方式。

例如，如果我有几个 li像这样的文字:

1) abc-def 200-201
2) fgh 204
3) hjk-lef 203

我想像这样对它们进行排序(最后一个数字是排序的重要内容，因此在(3)重要的是 201 的情况下):

1) fgh 204
2) hjk-lef 203
3) abc-def 200-201

我曾经认为可以在临时 Node 上 trim 单词，然后按降序对数字进行排序，但在我需要工作的 Node 上放置正确的顺序时遇到了麻烦。

有什么想法吗？

这是我使用 sort prototype 让它工作的方法和 regular expressions
