XPath - “获取第一个 tr，其中第一个 td 的文本等于 'abcd'”

Question

我目前有以下xpath：//tr[td//text()='AD'][1]

根据我的理解，这意味着："find the first tr which has some td child which has any descendant whose text is equal to 'AD'"

它是否正确？如果是这样，我想将 xpath 更改为以下定义：

"find the first tr whose second td child has text equal to 'AD'"

Answer 1

“找到第一个 tr，其第二个 td 子项的文本等于‘AD’”

可能会被实现为

//tr[td[position()=2 and text()="AD"]]
