Question

我是python的新手，我试图检查哪个div类首先出现在页面上。我用表格行完成了这项工作，但我似乎无法用div来解决这个问题。

我要确定的最新更新是发送的电子邮件<div class="EMAIL SENT">还是添加了<div class="Notes">的备注。最新项目将首先显示在顶部，但此后可能已执行其他操作，例如<div class="Updated">

我没有设法编写任何代码来执行此操作或事件接近，但在我的脑海中，我想它会像这样工作。

for sub_div_classes in browser.find_element_by_class_name('cb'):
    classname = ~check name of sub_div_class
    if classname = "EMAIL SENT":
        class_info = browser.find_element_by_class_name('plus_header_Additional_info').text
        print(class_info) ¬output: EMAIL SENT&nbsp;:Email sent on 20-03-2016 00:22:09 by [REDACTED]
        trigger_1()
    if classname = "Notes":
        trigger_2()
    ~move on to next div class in list

以下是我尝试使用的网页代码。我真的很感激任何人可以提供的任何建议或帮助。

<div class="cb" style="margin:5px 0 0 0;">
                              <div class="Updated">

Answer 1

使用带有xpath的or：

.xpath("//div[@class='Notes' or @class='EMAIL SENT']")[0]

如果Notes首先出现，您将获得Notes，反之亦然。

如果我们更改了下面的html代码段，请向<div class="EMAIL SENT">in email添加一些文字，并将以后的代码类更改为<div class="Notes">in notes：

我们可以看到使用lxml它是如何工作的：

In [13]: from lxml.etree import fromstring, HTMLParser

In [14]: xml = fromstring(html, HTMLParser())

In [15]: xml.xpath("//div[@class='Notes' or @class='EMAIL SENT']")
Out[15]: [<Element div at 0x7f96598d4ea8>, <Element div at 0x7f96598d4ef0>]

In [16]: xml.xpath("//div[@class='Notes' or @class='EMAIL SENT']")[0].text
Out[16]: 'in email\n                               '

In [17]: xml.xpath("//div[@class='Notes' or @class='EMAIL SENT']")[1].text
Out[17]: 'in notes\n

因此，对于selenium，您只想通过xpath找到元素。
