Я новичок в поиске в Интернете. BeautifulSoup ничего мне не дает. Это странно. PS Я использовал «html.parser», чтобы заменить «lxml», который также не работает.
from urllib.request import urlopen
>>> from bs4 import BeautifulSoup
>>> html = urlopen("http://www.pythonscraping.com/pages/page1.html")
>>> bsObj = BeautifulSoup(html.read())
Warning (from warnings module):
File"C:\Users\Administrator\AppData\Local\Programs\Python\Python36\lib\site-
packages\bs4\__init__.py", line 181
markup_type=markup_type))
UserWarning: No parser was explicitly specified, so I'm using the best
available HTML parser for this system ("lxml"). This usually isn't a
problem, but if you run this code on another system, or in a different
virtual environment, it may use a different parser and behave differently.
The code that caused this warning is on line 1 of the file <string>. To get
rid of this warning, change code that looks like this:
BeautifulSoup(YOUR_MARKUP})
to this:
BeautifulSoup(YOUR_MARKUP, "lxml")
>>> bsObj = BeautifulSoup(html.read(),"lxml")
>>> print(bsObj.h1)
None
>>> bsObj = BeautifulSoup(html.read())
>>> print(bsObj.h1)
None
