How to Xpath query all option tags containing the same attribute value
问题
我正在尝试查询所有带有标记为Book1的data-store值的选项标签内的文本。以下是主题下拉列表。
<div class="form-group">
<label>Cards</label>
<select class="form-control giftcard-selector" name="giftcard">
<option data-store="Book1" data-number="110" data-pin="333" data-balance="93.92" value="81372" style="display: none;">Book1: 1110 ($93.92)</option>
<option data-store="Book2" data-number="111" data-pin="0619" data-balance="7.56" value="81371" style="display: none;">Book2: 112 ($7.56)</option>
<option data-store="Book1" data-number="113" data-pin="8229" data-balance="10.24" value="81369" style="display: none;">Book1: 113 ($10.24)</option>
<option data-store="Book2" data-number="114" data-pin="0984" data-balance="2.17" value="81373" style="display: none;">Book2: 115 ($2.17)</option>
</select>
</div>
我尝试了以下xpath来查询所有带有标记为"Book1"的data-store值的选项标签内的所有文本，但返回为"Null"。非常感谢您的帮助。
//select[@class="form-control giftcard-selector"]/option[@data-store="Book1"]

我认为你的 XPath 写错了，尝试这样写：
对于元素：
//select[@class="form-control giftcard-selector"]/option[@data-store="Book1"]
对于文本：
//select[@class="form-control giftcard-selector"]/option[@data-store="Book1"]/text()
英文:
I think you built your xpath wrongly, try this:
For the elements:
//select[@class="form-control giftcard-selector"]/option[@data-store="Book1"]
For the text:
//select[@class="form-control giftcard-selector"]/option[@data-store="Book1"]/text()

你可以使用：
cssSelector: ".form-control.giftcard-selector option[data-number='1']"

You can use:

如果您仔细查看<select>元素，所有子元素<option>的**style**属性都设置为display: none;。因此，Selenium无法以通用方式定位它们。
解决方法
可以推测，<option>标签中的文本也通过<ul>和一些<li>标签表示，您需要通过这些标签与选项元素进行交互。
参考资料
您可以在以下几个相关的详细讨论中找到更多信息：
- 使用Selenium和Java自动化基于jQuery的Bootstrap下拉菜单
- 如何使用Selenium从动态下拉菜单中选择选项？
- 我想从列表中选择一个下拉选项，但HTML中没有select标签，我不确定是否应该使用Select类
英文:
If you look at the <select> element closely, all the descendent <option> elements are having style attribute set as display: none;. So Selenium won't be able to locate them in a generic way.
Solution
Presumably, the texts within the <option> tags are also represented through a <ul> and a couple of <li> tags and you need to interact with the option elements through those tags.
