如何解决如何解析BeautifulSoup对象中的所有HTML标签？
我在解析嵌套的BeautifulSoup对象中的HTML标签时遇到了麻烦。在这里
def optionMenuChanged(*args):
print(args[0]) # prints var1 if assigned to foo,prints var2 if assigned to bar
foo = tk.StringVar(name = 'var1')
foo.trace('w',optionMenuChanged)
bar = tk.StringVar(name = 'var2')
bar.trace('w',optionMenuChanged)
choices = ['1','2','3']
menu = OptionMenu(frame,foo,*choices)
'''
do stuff with menu
'''
menu.SetVariable(bar) # SetVariable does not exist
'''
do other stuff with menu
'''
但是汤['data']是这样的词典列表：
response = requests.get(
'myurl',headers={'Authorization': 'Bearer ' + auth_token},params=params
)
soup = BeautifulSoup(response.content,'html.parser')
soup = json.loads(str(soup))
all_data.extend(soup['data'])
即使标签仅出现在[{"_id":"123","tags":[],"user":{"_id":"u1","name":"ASD Na"},"shared":"<p>Personal: Parents </p><p><br/></p><p>KM: </p><p><br/></p>","private":"","created":"2019-01-26T16:54:56.283Z","district":"543543","creator":{"_id":"c432","name":"Cass Man"},"lastModified":"2019-01-26T16:54:56.284Z"},{"_id":"234","user":{"_id":"u2","name":"Tyler Dass"},"shared":"Hi,<p>It's great to see your clear.</p>","created":"2019-11-26T15:48:43.314Z","creator":{"_id":"432","name":"John"},"lastModified":"2019-11-26T15:48:43.315Z"}]
键中，它们也确实出现在多个字段中。如何访问shared并使用各种BeautifulSoup函数在所有字段中获取所有正确的文本？我尝试使用soup，但这没用。
解决方法
从您看到的示例中，您正在获取JSON响应，因此您不需要BeautifulSoup来解析它：
response = requests.get('myurl',headers={'Authorization': 'Bearer ' + auth_token},params=params)
data = response.json() # <-- note the .json() call
all_data.extend(data['data'])
然后，要从shared键中获取信息，可以将其转换为BeautifulSoup对象：
for d in all_data:
soup = BeautifulSoup(d['shared'],'html.parser')
# print only text from <p> tags:
print([p.get_text(strip=True) for p in soup.select('p')])
打印：
['Personal: Parents','','KM:','']
["It's great to see your clear."]
