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

【参考方案1】：

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']
