使用Selenium，我们可以在下面实现您的目标：

from selenium import webdriver
from bs4 import BeautifulSoup

browser = webdriver.Firefox()
url = 'https://oehha.ca.gov/chemicals/abiraterone-acetate'
sada = browser.get(url)
source = browser.page_source
soup = BeautifulSoup(source, 'html.parser')

title = soup.find('h1', {'class': 'title'})
print(title.text.strip())
details = soup.find(string='Occurence(s)/Use(s)').find_next('p').contents[0]
print(details)
date = soup.find('span', {'class': 'date-display-single'})
print(date.text)

browser.close()

输出：

Abiraterone acetate
A CYP17 inhibitor indicated in combination with prednisone for the treatment of patients with metastatic castration-resistant prostate cancer.
