Get value of span tag using BeautifulSoup
提问by newaccount1111
I have a number of facebook groups that I would like to get the count of the members of. An example would be this group: https://www.facebook.com/groups/347805588637627/I have looked at inspect element on the page and it is stored like so:
我有许多 facebook 群组，我想了解其成员的数量。一个例子是这个组：https: //www.facebook.com/groups/347805588637627/我看过页面上的检查元素，它是这样存储的：
<span id="count_text">9,413 members</span>
I am trying to get "9,413 members" out of the page. I have tried using BeautifulSoup but cannot work it out.
我试图从页面中删除“9,413 名成员”。我曾尝试使用 BeautifulSoup，但无法解决。
Thanks
谢谢

编辑：
from bs4 import BeautifulSoup
import requests
url = "https://www.facebook.com/groups/347805588637627/"
r = requests.get(url)
data = r.text
soup = BeautifulSoup(data, "html.parser")
span = soup.find("span", id="count_text")
print(span.text)

In case there is more than one span tag in the page:
如果页面中有多个 span 标签：
from bs4 import BeautifulSoup
soup = BeautifulSoup(your_html_input, 'html.parser')
span = soup.find("span", id="count_text")
span.text

You can use the textattribute of the parsed span:
您可以使用text解析跨度的属性：
>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup('<span id="count_text">9,413 members</span>', 'html.parser')
>>> soup.span
<span id="count_text">9,413 members</span>
>>> soup.span.text
'9,413 members'

If you have more than one span tag you can try this
如果你有多个 span 标签，你可以试试这个
from bs4 import BeautifulSoup
soup = BeautifulSoup(html, 'html.parser')
tags = soup('span')
for tag in tags:
print(tag.contents[0])
