我无法找到/找到Selenium中的下拉列表的xpath

Question

我无法在Selenium中的下拉列表中找到/找到xpath，下拉列表是使用div标签编写的，并且悬停时更改了attribute（aria-activedescendant）值。在下拉列表中选择的值一经出现，attribute（aria-activedescendant）值就会消失。

有什么可以帮助我为此找到xpath的吗？提前致谢。

HTML如下：

<div class="DropdownWidget---dropdown_value DropdownWidget---placeholder"

id="189d67819beda8ebc9b5a2b7554f80f1_value" 

role="listbox" 

tabindex="0" 

aria-controls="189d67819beda8ebc9b5a2b7554f80f1_list" 

aria-expanded="false" 

aria-activedescendant="" 

aria-labelledby="189d67819beda8ebc9b5a2b7554f80f1" 

aria-describedby="189d67819beda8ebc9b5a2b7554f80f1_selectedChoice" 

aria-required="true">

<!-- react-text: 38 -->- Please Select a Value -<!-- /react-text -->

<span id="189d67819beda8ebc9b5a2b7554f80f1_selectedChoice" 

class="DropdownWidget---accessibilityhidden">- Please Select a Value -</span> 

</div>

鼠标悬停时，属性值正在更改，如下所示：

aria-activedescendant=189d67819beda8ebc9b5a2b7554f80f1_list_0

aria-activedescendant=189d67819beda8ebc9b5a2b7554f80f1_list_1

aria-activedescendant=189d67819beda8ebc9b5a2b7554f80f1_list_2

aria-activedescendant=189d67819beda8ebc9b5a2b7554f80f1_list_3

以下是检查的选项代码：

<div class="DropdownWidget---dropdown_value DropdownWidget---placeholder" id="189d67819beda8ebc9b5a2b7554f80f1_value" role="listbox" tabindex="0" aria-controls="189d67819beda8ebc9b5a2b7554f80f1_list" aria-expanded="true" aria-activedescendant="189d67819beda8ebc9b5a2b7554f80f1_list_2"

  aria-labelledby="189d67819beda8ebc9b5a2b7554f80f1" aria-describedby="189d67819beda8ebc9b5a2b7554f80f1_selectedChoice" aria-required="true">

  <!-- react-text: 38 -->- Please Select a Value -

  <!-- /react-text --><span id="189d67819beda8ebc9b5a2b7554f80f1_selectedChoice" class="DropdownWidget---accessibilityhidden">- Please Select a Value -</span></div>
