如何使用XPath根据其子元素查找父元素

我正在创建一个函数来返回给定元素的XPath。为此，我需要找到一种获取给定子元素的父元素的方法。

我想知道是否有办法做到这一点：

{
  "id": "1",
  "firstName": "Min",
  "lastName": "Heo"
}

想法是基于已知的子元素获取父元素。

使用WebElement时可以正常工作，但使用AndroidElement时则无法工作。

编辑 这是页面的XML：

AndroidElement parentElement = childElement.findElement(By.xpath("SOME_XPATH_value"));

例如，我想获取以下元素的父元素：

<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>

        </android.view.ViewGroup>
      </android.widget.FrameLayout>
    </android.widget.LinearLayout>
  </android.widget.FrameLayout>
</hierarchy>

应该是：

<android.widget.TextView index="0" package="io.testproject.demo" class="android.widget.TextView" text="Full Name" resource-id="io.testproject.demo:id/labelFullName" checkable="false" checked="false" clickable="false" enabled="true" focusable="false" focused="false" long-clickable="false" password="false" scrollable="false" selected="false" bounds="[24,240][1056,297]" displayed="true" />

答案 0 :(得分：0)

尝试将以下内容用作xpath表达式，并查看其是否有效：

//hierarchy//*[local-name()='android.widget.TextView'][@resource-id="io.testproject.demo:id/labelFullName"]/parent::*

或者只是

//hierarchy//android.widget.TextView[@resource-id="io.testproject.demo:id/labelFullName"]/parent::*
