Pagination xpath invalid - css

Question

I wanted to navigate to next page but the robot always returned error
How do I construct the xpath with this <li title="2" class="ant-pagination-item ant-pagination-item-2" tabindex="0">
or <li title="Next Page" class="ant-pagination-next"

Answer 1

You are using this xpath
//title[#class="ant-pagination-item ant-pagination-item-2"])
which is wrong, cause xPath expression are written like this
//tagName[#attributeName='attributeValue']
so your xpath should be
//li[#class='ant-pagination-item ant-pagination-item-2']
Also, You can have this xpath, since you are mainly looking for pagination, index wouldn't hurt [See below]
//li[#title='2']
