Wikipedia web刮表有问题

Question

from bs4 import BeautifulSoup as Soup,Tag
import requests

f=open("temples.txt","a+")

url=r"https://en.wikipedia.org/wiki/January_1"

r = requests.get(url)
soup = Soup(r.content,"html.parser" )

temple_span=soup.find("span",{"id":"Births"})
temples_ul=temple_span.parent.find_next_sibling()


for item in temples_ul.findAll('li'):
    if isinstance(item,Tag):
        print (item.text)

但如果li和span之间有一些额外的数据，它就不起作用了。例如：https://en.wikipedia.org/wiki/Lists_of_tourist_attractions

代码：

</span></span></h3>

上面的代码不起作用，因为有一个div。 我怎样才能得到与上面相同的输出，但只有li

试一试：

from bs4 import BeautifulSoup as Soup,Tag
import requests

url=r"https://en.wikipedia.org/wiki/Lists_of_tourist_attractions"

r = requests.get(url)
soup = Soup(r.text,"html.parser" )

for ul in soup.findAll('div'):
    print(ul.text)
    for li in ul.findAll('li'):
        print(li.text)
