推荐答案

有很多方法可以使用 XPath 访问元素.例如，您可以通过节点名称或通过其属性或子节点之一的值来访问它.所以你不能指望 javascript 给你其中之一.

There are many ways howto access an element with XPath. For example you can access it by node name or by the value of one of it's attributes or child nodes. So you can not expect that javascript gives you exactly one of them.

但是由于您拥有 id，因此访问元素的最简单的 xpath 查询是:

But as you have the id, the simplest xpath query to access the element would be:

//*[@id="THE_ID"]
