find_all 也找不到作品

Question

我试图在我们选择的用户的页面上抓取每个收藏夹的名称。但是使用这段代码我得到错误“ResultSet object 没有属性 'find_all'”但是如果我尝试使用 find 它会得到相反的错误并且它要求我使用 find_all。我是初学者，我不知道该怎么做。（同样为了测试代码，您可以使用用户名“Kineta”，她是管理员，这样任何人都可以访问她的个人资料页面）。感谢您的帮助

from bs4 import BeautifulSoup
import requests

usr_name = str(input('the user you are searching for '))
html_text = requests.get('https://myanimelist.net/profile/'+usr_name)
soup = BeautifulSoup(html_text.text, 'lxml')
favs = soup.find_all('div', class_='fav-slide-outer')
favs_title = favs.find_all('span', class_='title fs10')
print(favs_title)

Answer 1

您的程序抛出异常，因为您试图在 ResultSet 上使用 .find_all (favs_title = favs.find_all(...), ResultSetdoesn't have function.find_all`).相反，您可以直接使用 CSS select 或 select 所有必需的元素：

import requests
from bs4 import BeautifulSoup

url = "https://myanimelist.net/profile/Kineta"
soup = BeautifulSoup(requests.get(url).content, "html.parser")

for t in soup.select(".fav-slide .title"):
    print(t.text)

编辑：要获得 Anime/Manga/Character 个收藏夹：

import requests
from bs4 import BeautifulSoup

url = "https://myanimelist.net/profile/Kineta"
soup = BeautifulSoup(requests.get(url).content, "html.parser")


anime_favorites = [t.text for t in soup.select("#anime_favorites .title")]
manga_favorites = [t.text for t in soup.select("#manga_favorites .title")]
char_favorites = [t.text for t in soup.select("#character_favorites .title")]

print("Anime Favorites")
print("-" * 80)
print(*anime_favorites, sep="\n")
print()

print("Manga Favorites")
print("-" * 80)
print(*manga_favorites, sep="\n")
print()

print("Character Favorites")
print("-" * 80)
print(*char_favorites, sep="\n")

Answer 2

查找和find_all工作你只需要正确使用它们。您不能使用它们来搜索列表（例如示例中的 'favs' 变量）。您始终可以使用 for 循环遍历列表并使用 'find' 或 'find_all' 函数。

我更喜欢让它更容易一些，但你可以选择你喜欢的方式，因为我不确定我的方式是否更有效率：

from bs4 import BeautifulSoup
import requests

usr_name = str(input('the user you are searching for '))
html_text = requests.get('https://myanimelist.net/profile/'+usr_name)
soup = BeautifulSoup(html_text.text, 'lxml')
favs = soup.find_all('div', class_='fav-slide-outer')
for fav in favs:
    tag=fav.span
    print(tag.text)

如果您需要有关如何正确使用 bs4 函数的更多信息，我建议您查看他们的扩展坞 here。

我看了看页面，改了一下代码，这样你应该得到你需要的所有结果：

from bs4 import BeautifulSoup
import requests

usr_name = str(input('the user you are searching for '))
html_text = requests.get('https://myanimelist.net/profile/'+usr_name)
soup = BeautifulSoup(html_text.text, 'lxml')
favs = soup.find_all('li', class_='btn-fav')
for fav in favs:
    tag=fav.span
    print(tag.text)

我认为这里的问题不在于代码，而在于您搜索结果的方式以及网站的结构。
