>>> html = "<foo>Something something <bar> blah blah</bar> something</foo>" 
>>> bs(html).find_all('foo')[0] 
<foo>Something something <bar> blah blah</bar> something else</foo> 
>>> bs(html).find_all('foo')[0].text 
u'Something something blah blah something else'

Answer 1

您可以檢查bs4.element.NavigableString兒童：

from bs4 import BeautifulSoup as bs 
import bs4 
html = "<foo>Something something <bar> blah blah</bar> something <bar2>GONE!</bar2> else</foo>" 
def get_only_text(elem): 
    for item in elem.children: 
     if isinstance(item,bs4.element.NavigableString): 
      yield item 

print ''.join(get_only_text(bs(html).find_all('foo')[0])) 

輸出;

Something something something else

例如，

body = bs(html) 
for tag in body.find_all('bar'): 
    tag.replace_with('')
