每个“7件装”搜索结果here包含多个评论,例如“5条评论”,没有评论“等。
每个的类名是fl r-iNTHbQvDybDU
。它包含一个空格,所以如果我尝试find_elements_by_class_name(),我得到:
InvalidSelectorError: Compound class names not permitted
根据这里的其他答案,我需要做的就是移除空间并重试。没有运气 - 空名单
所以我尝试find_element_by_css_selector()
:
find_elements_by_css_selector(".fl.r-iNTHbQvDybDU")
仍然没有运气 - 空单。接下来你会尝试什么?

这个怎么样:
browser.find_elements_by_css_selector("div[class='fl r-iNTHbQvDybDU']")
这假定为class = div
。
如果是其他的话 - 否则用适当的标签替换div ..

我不会依赖这些自动生成的类名。除了不可靠之外,它还会降低您的代码的可读性。相反,请获取包含“审核”文本的链接。

你需要在它前面添加标签名称。
例如,它位于div元素内,然后:
Selenium.find_element_by_class_name(div.ur.class.name)
