Фильтр h1 HTML с BeautifulSoup

Question

Я пишу Алгоритм КОДА НИЖЕ :

from selenium import webdriver
from bs4 import BeautifulSoup
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import requests
import time
browser =webdriver.Firefox(executable_path=r'C:/path/geckodriver.exe')
browser.get('https://brainly.com.br/app/ask?entry=hero&q=15+12')
WebDriverWait(browser,10).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR,'a[href*="/tarefa"]')))
html=browser.page_source
#html = browser.execute_script("return document.documentElement.outerHTML")
p=[]
soup=BeautifulSoup(html,'html.parser')
for link in soup.select('div.sg-actions-list__hole > a[href*="/tarefa"]'):
    ref=link.get('href')
    rt = ('https://brainly.com.br'+str(ref))
    p.append(rt)

g=[]
for url in p:
    r = requests.get(url).text
    time.sleep(10)


rs= BeautifulSoup(r,'html.parser')


df = rs.select('div > h1')
print(df) 

HTML Мне нужно отфильтровать:

<div class="brn-content-image">
<h1 class="sg-text sg-text--large sg-text--regular">
Tinha 12 cruzeiros e gastei 15 cruzeiros esta situação pode ser representada por a 15 - 12 B 12 + 15 C 12 - 11 e D - 12 + 15
</h1>
</div> 

И

<div class="brn-content-image">
<h1 class="sg-text sg-text--large sg-text--regular">
[(-15)12]12:(-15)142?
</h1>
</div> 

В переменной r Я храню исходный код для 8 URL-адресов, ie 8 Исходный код, который, я не уверен, является проблемой, с которой я не могу отфильтровать его.

Использование кода для фильтрации HTML:

rs= BeautifulSoup(r,'html.parser')
df = rs.select('div > h1')
print(df)

Какую ошибку я делаю?.

Answer 1

Вместо использования Selenium, вы можете вызвать API напрямую, который отображает JavaScript, используя XHR запрос.

import requests

data = [{"operationName": "SearchQuery", "variables": {"query": "15 12", "after": None, "first": 10},
         "query": "query SearchQuery($query: String!, $first: Int!, $after: ID) {\n  questionSearch(query: $query, first: $first, after: $after) {\n    count\n    edges {\n      node {\n        id\n        databaseId\n        author {\n          id\n          databaseId\n          isDeleted\n          nick\n          avatar {\n            thumbnailUrl\n            __typename\n          }\n          rank {\n            name\n            __typename\n          }\n          __typename\n        }\n        content\n        answers {\n          nodes {\n            thanksCount\n            ratesCount\n            rating\n            __typename\n          }\n          hasVerified\n          __typename\n        }\n        __typename\n      }\n      highlight {\n        contentFragments\n        __typename\n      }\n      __typename\n    }\n    __typename\n  }\n}\n"}]
r = requests.post("https://brainly.com.br/graphql/pt", json=data).json()


for item in r[0]['data']['questionSearch']['edges']:
    print(item['node']['content'])

Попробуйте с этим:

from bs4 import BeautifulSoup

html = """
<div class="brn-content-image">
<h1 class="sg-text sg-text--large sg-text--regular">
Tinha 12 cruzeiros e gastei 15 cruzeiros esta situação pode ser representada por a 15 - 12 B 12 + 15 C 12 - 11 e D - 12 + 15
</h1>
</div>
<div class="brn-content-image">
<h1 class="sg-text sg-text--large sg-text--regular">
[(-15)12]12:(-15)142?
</h1>
</div> 
       """
soup = BeautifulSoup(html,'html.parser')

for n in soup.find_all('div', attrs={'class': 'brn-content-image'}):    
   print(n.find('h1').text)
