我正在使用 Python 3.7 和 BeautifulSoup 4。我想找到出现在“td.info”元素中的所有“div.title”元素。CSS 选择器（我相信）看起来像
td.info div.title
所以我想我可以得到这样的元素
elts = soup.findAll("td", {"class": "info"}).find("div", {"class": "title"})
for div in elts:
但相反我收到错误

AttributeError: ResultSet object has no attribute 'find'. You're probably treating a list of items like a single item. Did you call find_all() when you meant to call find()?
是什么赋予了？
对 td 使用 find()，对 div 元素使用 find_all()
elts = soup.find("td", class_="info").find_all("div", class_="title")
for div in elts:
print(div['title'])
如果您有多个 td 标签，如果您有多个 div 标签，则在 td 下尝试以下操作。
for td in soup.find_all("td", class_="info"):
for div in td.find_all("div", class_="title"):
print(div['title'])
使用 css
for td in soup.select("td.info"):
for div in td.select("div.title"):
print(div['title'])
