Question

尝试通过以下方式阅读Likedin feed的评论：

        comments = browesr.find_elements_by_xpath("//*[@class='comments-comments-list__comment-item comments-comment-item ember-view']")
        print(comments[0].id)
        print(comments[1].id)
        print(comments[2].id)
        print(comments[0].get_attribute("id"))
        print(comments[1].get_attribute("id"))
        print(comments[2].get_attribute("id"))
        print(comments[0].find_element_by_xpath("//*[@data-control-name='comment_actor_description']").text)
        print(comments[1].find_element_by_xpath("//*[@data-control-name='comment_actor_description']").text)
        print(comments[2].find_element_by_xpath("//*[@data-control-name='comment_actor_description']").text)

输出：

0.854587949237863-1
0.854587949237863-2
0.854587949237863-3

您可以看到ID是不同的，但是每个ID中的元素都是相同的（第一个），这可能是什么问题？

Answer 1

只需替换XPath

"//*[@data-control-name='comment_actor_description']"

使用

".//*[@data-control-name='comment_actor_description']"

Selenium find_elements一遍又一遍地返回相同的元素
