使用BeautifulSoup抓取該欄位

我無法使用 BeautifulSoup獲取當前欄位“型別”。

當前代碼為“型別”變數列印空白

from bs4 import BeautifulSoup
import requests

url='https://ash.confex.com/ash/2021/webprogram/Session20851.html'

res = requests.get(url)
soup = BeautifulSoup(res.content,'html.parser')

content=soup.find_all('div',class_='paper')

for property in content:
    title=property.find('div',class_='cricon').text
    type=property.find("div",{"id":"info"})

正如您在這里看到的，在每次內容迭代期間，這看起來像是一個“屬性”變數。

換句話說，您正在迭代每個事件，但您只需要獲取標題 div，在 ID 中稱為“資訊”。

這應該對你有用......

from bs4 import BeautifulSoup
import requests

url='https://ash.confex.com/ash/2021/webprogram/Session20851.html'

res = requests.get(url)
soup = BeautifulSoup(res.content,'html.parser')

content=soup.find_all('div',class_='paper')
info = soup.find_all('div',class_ = 'datetime')
type = soup.find("span", string="Type:").next_sibling


for property in content:
    title=property.find('div',class_='cricon').text
    print(title, type, sep = "\n", end = "\n\n")

如果您只查找“口頭”文本，那么您實際上不需要遍歷整個內容。你正在尋找這個：

result = soup.select_one('#info span:nth-child(3)').next_sibling.strip()

# Oral

在線 IDE 中的完整代碼和示例：

from bs4 import BeautifulSoup
import requests

url='https://ash.confex.com/ash/2021/webprogram/Session20851.html'

res = requests.get(url)
soup = BeautifulSoup(res.content,'html.parser')

result = soup.select_one('#info span:nth-child(3)').next_sibling.strip()
print(result)

# Oral
