美丽的汤.找不到任何东西 [英] beautiful soup .find can't find anything

问题描述

我正尝试在Facebook网上论坛中删除帖子:

I am trying to scrap posts in a Facebook group:

URL = 'https://www.facebook.com/groups/110354088989367/'

headers = {
    "User-Agent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36'
}


def checkSubletGroup():
    page = requests.get(URL, headers=headers)
    soup = BeautifulSoup(page.content, 'html.parser')
    posts = soup.find_all("div", {"class_": "text_exposed_root"})
    print(soup.prettify())
    for post in posts:
        print(post)


checkSubletGroup()

带有 class ="text_exposed_root" 的 div 显然在那里，因为我可以使用 CTRL f 找到它当我在 print(soup.prettify())中进行搜索时，但是当我在 soup.find_all("div"，{"class_":"text_exposed_root"})中进行搜索时返回一个空列表，显然还有许多其他的类名.

The div with class="text_exposed_root" is clearly there because I can find it with CTRLf when I search in print(soup.prettify()), but when I do soup.find_all("div", {"class_": "text_exposed_root"}) it is returning an empty list, so are many other class names that are clearly there.

请帮助.

推荐答案

问题是所有这些< div> 都在注释掉的HTML块内.

The problem is that all those <div> are inside a commented out HTML block.

类似的方法可以解决此问题:

Something like this can workaround the issue:

soup = BeautifulSoup(page.text.replace('<!--', '').replace('-->', ''), 'html.parser')

之后，您可以简单地执行以下操作:

After that you can simply do:

posts = soup.find_all('div', 'text_exposed_root')
