如何使用 XPath 根据其子元素查找父元素

Question

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

我想知道是否有这样的方法：

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

思路是根据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 时就不行了。

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

所以，例如，我想获取以下的父元素：

<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" />

应该是：

<android.widget.LinearLayout index="0" package="io.testproject.demo" class="android.widget.LinearLayout" text="" resource-id="io.testproject.demo:id/name_components" checkable="false" checked="false" clickable="false" enabled="true" focusable="false" focused="false" long-clickable="false" password="false" scrollable="false" selected="false" bounds="[24,240][1056,874]" displayed="true">

Answer 1

尝试使用以下作为您的 xpath 表达式，看看它是否有效：

//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::*
