how to get element with xpath by attribute value
问题
从此页面尝试获取下一页箭头链接。然而，response.selector.xpath('//a[aria-label="Next page"]')返回的是[]。帮助！ 
我能够用response.selector.xpath('//*[contains(@class, "Pagination_arrowItem")]/a')[1].attrib['href']来解决，但是如果是第一页并且只显示一个箭头，则会遇到问题。

I was able to solve it with response.selector.xpath('//*[contains(@class, "Pagination_arrowItem")]/a')[1].attrib['href'] but then run into an issue if it's the firts page and only one arrow is shown.

Since the anker itself is using a workable @data-e2e-test attribute, its name seems a bit temporary. Therefore you also could use:
// *[starts-with(@class, "Pagination_container")]/div[position()=last()]/a
