Webdriver findElements通过xpath

1)我正在做一个教程来展示xpath的findElements如何工作.我想知道为什么它返回带有属性id=container的<div>元素之后的所有文本.

1)I am doing a tutorial to show how findElements By xpath works. I would like to know why it returns all the texts that following the <div> element with attribute id=container.

xpath的代码:By.xpath("//div[@id='container']

code for xpath: By.xpath("//div[@id='container']

2)我应该如何修改代码，使其仅返回父注释后面的第一个或前几个节点 例如第一个节点(如家庭")，前几个节点(如家庭，手动测试和自动化测试).

2) how should I modify the code so it just return first or first few nodes that follow the parent note e.g. first node like 'Home', first few node like, Home, Manual Testing and Automation Testing.

感谢您的建议和帮助！

这是本教程的代码片段:
