所以我希望 selenium 打开具有“mod-tile”类的第一个链接，然后它会执行我制作的脚本，然后我希望它打开下一个链接具有相同的类“mod-tile”。有没有办法指定这个？（顺便说一句，不要介意我刚刚复制了网站上出现的前 3 个模块图块的描述）

【问题讨论】：

标签： python selenium-webdriver

【解决方案1】：

您可以使用 find_elements_by_class_name() 方法获取元素列表。然后遍历元素列表。

[更新] 以下应单击“mod-tile”元素中的第一个链接（//a）

elements = driver.find_elements_by_class_name("mod-tile")
print("mod-title count {}".format(len(elements)))

for element in range(len(elements)):
  elements[element].find_element_by_xpath("//a").click()

【讨论】：

抱歉，我是 selenium 新手，如何遍历元素？
示例代码演示了遍历元素。第一行获取具有类名的元素列表。然后 for 循环遍历元素列表。
将代码粘贴到我的脚本中，它只打开 1 个链接，而且它似乎没有运行我拥有的其余代码（查找并单击文件 -> 查找并单击手动下载）跨度>
代码已更新为单击每个 mod-tile 部分的第一个链接。添加了 print 语句以检查带有 mod-tile 的元素。这应该不止一个。否则我们需要进一步调查。
更新后的代码对我不起作用，它将标签发送到 nexusmods.com 基础站点而不是 mods，pastebin link + github for code at bottom
