问题描述
我有这个
from urllib import request
url = "http://www.bbc.co.uk/news/election-us-2016-35791008"
html = request.urlopen(url).read().decode('utf8')
html[:60]
from bs4 import BeautifulSoup
raw = BeautifulSoup(html, 'html.parser').get_text()
raw.find_all('title', limit=1)
print (raw.find_all("title"))
'<!doctype html public "-//W3C//DTD HTML 4.0 Transitional//EN'
我想使用BeautifulSoup提取页面标题，但出现此错误
I want to extract the title of the page using BeautifulSoup but getting this error
Traceback (most recent call last):
File "C:\Users\Passanova\AppData\Local\Programs\Python\Python35-32\test.py", line 8, in <module>
raw.find_all('title', limit=1)
AttributeError: 'str' object has no attribute 'find_all'
请提出任何建议
推荐答案
要浏览汤，您需要BeautifulSoup对象，而不是字符串.因此，删除对汤的get_text()调用.
To navigate the soup, you need a BeautifulSoup object, not a string. So remove your get_text() call to the soup.
此外，您可以将raw.find_all('title', limit=1)替换为等效的find('title').
Moreover, you can replace raw.find_all('title', limit=1) with find('title') which is equivalent.
尝试一下:
from urllib import request
url = "http://www.bbc.co.uk/news/election-us-2016-35791008"
html = request.urlopen(url).read().decode('utf8')
html[:60]
from bs4 import BeautifulSoup
soup = BeautifulSoup(html, 'html.parser')
title = soup.find('title')
print(title) # Prints the tag
print(title.string) # Prints the tag string content
