如何通过xpath获取元素的索引？ [英] How to get element's index by xpath?

问题描述

我的下一个结构是：

<div id='list'>
   <div class='column'>aaa</div>
   <div class='column'>bbb</div>
   ...
   <div class='column'>jjj</div>
</div>

我想知道是否存在使用XPath的方法，并且可以写一些查询来获得

I was wonder if there is a ways to use XPath, and to write some query were I can get the index of the requested element within the "list" element.

我的意思是我要询问 class ='column'，其中文本值为 aaa ，我将得到 0 或 1 ...

I mean that I'll ask for location of class='column' where the text value is aaa and I'll get 0 or 1...

谢谢

推荐答案

您可以只在要查找的元素之前计算div元素：

You could just count the div elements preceding the element you're looking for:

count(div[@id = 'list']/div[@id = 'myid']/preceding-sibling::div)
