使用Appium for Java的ios UI自动化。 使用xPath无法找到元素

Question

I am trying to get specific element using XPath. I am using the following XPath for given XML, to get button elements. It always shows error, unable to find element using specified source

//XCUIElementTypeApplication[1]/XCUIElementTypeWindow[1]/XCUIElementTypeOther[1]/XCUIElementTypeOther[2]/XCUIElementTypeTabBar[1]/XCUIElementTypeButton[1]

//XCUIElementTypeApplication[1]/XCUIElementTypeWindow[1]/XCUIElementTypeOther[1]/XCUIElementTypeOther[2]/XCUIElementTypeTabBar[1]/XCUIElementTypeButton[2]

//XCUIElementTypeApplication[1]/XCUIElementTypeWindow[1]/XCUIElementTypeOther[1]/XCUIElementTypeOther[2]/XCUIElementTypeTabBar[1]/XCUIElementTypeButton[3]

XML pagesource is

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

//XCUIElementTypeButton[1]

//XCUIElementTypeButton[2]

//XCUIElementTypeButton[3]

Above command works.

I have modified your code and given it below, if you needed try it out. (//XCUIElementTypeApplication[1]/XCUIElementTypeWindow[1]/XCUIElementTypeOther[1]/XCUIElementTypeOther)[2]/XCUIElementTypeTabBar[1]/XCUIElementTypeButton[1]
