美丽的汤。如何在一次搜索中找到具有特定属性但属性值不同的标签？

Question

我正在尝试通过一个搜索请求从一个论坛主题中获取所有帖子，以便以正确的顺序获取列表。我可以得到的大多数帖子：

soup.find_all('div', attrs={'class': 'post_wrap'}

但是也可以找到以下帖子：

soup.find_all('div', attrs={'class': 'post_wrap__staff'}

因此，属性相同，但属性值不同。我可以在一个请求中同时获得两种类型的帖子吗？像这样：

soup.find_all('div', attrs={'class': 'post_wrap' and 'post_wrap__staff'}

这取决于您使用的BeautifulSoup版本。在the docs中查看bs3，看起来您正在寻找的是类似以下内容的

当您使用 Python 3 对其进行标记时，我假设您正在使用bs4。 The docs声明您可以执行以下操作：

soup.findAll(class=['post_wrap', 'post_wrap__staff']}

但是正如a similar question about multiple attributes中所述，最好像下面这样use CSS selectors：

soup.find_all("div", attrs={"class": ["post_wrap", "post_wrap__staff"]})
