css - 分页 xpath 无效

问题描述

我想导航到下一页，但机器人总是返回错误

我如何用这个<li title="2" class="ant-pagination-item ant-pagination-item-2" tabindex="0"> 或 <li title="Next Page" class="ant-pagination-next"

脚本：

解决方案

你正在使用这个xpath

//title[@class="ant-pagination-item ant-pagination-item-2"])

这是错误的，因为 xPath 表达式是这样写的

//tagName[@attributeName='attributeValue']

所以你的xpath应该是

//li[@class='ant-pagination-item ant-pagination-item-2']

另外，你可以有这个 xpath，因为你主要是在寻找分页，索引不会伤害[见下文]

//li[@title='2']
