英文:
Why I find two elements using xpath when I specify index?
问题
我正在编写自动化测试。
用于查找元素，我正在使用XPATH。
现在，我需要获取元素列表，通常我会编写包含表格类名称和子元素的XPATH。我的页面上有2个表格，我的XPATH可以同时找到这两个表格，但是当我使用索引1时，也会找到第二个表格，当我使用索引2时，却什么都找不到。
这是如何工作的？为什么我不能选择第二个元素？
英文:
I'm writing autotests.
For finding elements I'm using XPATH.
Now I need get list of element, as usual I write xpath which contains class name of table and childs elements. My page has 2 tables, and my XPATH can find both, but when I'm using index 1 I also find second table, when I'm using index 2 I find nothing.
How does it work? Why I can't choose second element

根据我所看到的XPath片段，您正在选择第一个后续兄弟table元素的子元素tbody。大多数table只会有一个tbody元素。因此，在第一个XPath中添加[1]来获取第一个tbody时，您会得到它。在第二个XPath中添加[2]来获取该table的第二个tbody时，没有要选择的内容，因此什么都不会得到。
英文:
From the pieces of the XPath that I can see, at the step in which you are selecting the tbody element that is the child of the first following-sibling table element.
Most table will only have one tbody element.
So, in the first XPath where you add [1] asking for the first tbody, you get it. In the second XPath where you are asking for [2], the second tbody that is the child of that table, there aren't any to select and you get nothing.

我相当确定问题出在你的XPath中红色部分。
所以在你的XPath中红色部分会有2个带有表格的元素。
要只选择第一个元素，你可以像这样将()放在它们周围：
(//div[@class='with-some-classname']/following-sibling::table)1/tbody
另一个选项是在XPath的红色部分中将表格作为谓词使用，就像这样：
(//div[@class='with-some-classname'][following-sibling::table])1/following-sibling::table1/tbody
英文:
I'm pretty sure that the reason liesin the red part of your XPath.
So in the red part of your XPath will have 2 elements with a table.
To only select the first one you can put () around them like this:
(//div[@class='with-some-classname']/following-sibling::table)[1]/tbody
An other option would be to use the table as a predicate in your red part of the XPath like this i.e.:
(//div[@class='with-some-classname'][following-sibling::table])[1]/following-sibling::table[1]/tbody
