推荐答案

常规

HTML中没有对 xpath ="1" 的标准解释，因为 select 元素上没有标准的 xpath 属性(或任何其他HTML元素).您偶然发现了某些应用程序的特有标记；您必须查阅应用程序的作者，文档或源代码，以了解 xpath ="1" 的语义.

In General

There is no standard interpretation of xpath="1" in HTML because there is no standard xpath attribute on a select element (or any other HTML element). You've stumbled across some application's idiosyncratic markup; you'll have to consult the application's authors, documentation, or source code to learn the semantics of xpath="1".

请进一步注意，添加应用程序或用户特定属性的正确方法是使用 data-前缀: data-xpath 对其进行命名.

Note further that the proper way to add an application or user specific attribute would have been to name it with a data- prefix: data-xpath.

有一个XPath实用程序 ChroPath ，它可以作为浏览器扩展程序运行，并编写 xpath元素上的(和 css )属性.信用: Randy Casburn回答对
