Скраб плохо закодированный html

Question

Я очистил веб-сайт с сотнями страниц плохо организованных HTML. Я использовал BeautifulSoup для захвата всего содержимого div на каждой странице. Вот выдержка из этого списка:

mylist = [['<div id="headingData">006951446<br/>Algonquin Gas Transmission, LLC<br/>Critical notice<br/>12/30/2019<br/>09:00:00 AM<br/>12/31/2019<br/>09:00:00 AM<br/>92112<br/>Initiate<br/>Capacity Constraint<br/>12/29/2019<br/>03:02:38 PM<br/> <br/><br/>No response required<br/> <br/> <br/>AGT Pipeline Conditions for 12/30/2019<br/></div>'],
['<div id="headingData">006951446<br/>Algonquin Gas Transmission, LLC<br/>Critical notice<br/>12/29/2019<br/>09:00:00 AM<br/>12/30/2019<br/>09:00:00 AM<br/>92086<br/>Initiate<br/>Capacity Constraint<br/>12/28/2019<br/>02:55:39 PM<br/> <br/><br/>No response required<br/> <br/> <br/>AGT Pipeline Conditions for 12/29/2019<br/></div>'],
['<div id="headingData">006951446<br/>Algonquin Gas Transmission, LLC<br/>Critical notice<br/>12/28/2019<br/>09:00:00 AM<br/>12/29/2019<br/>09:00:00 AM<br/>92074<br/>Initiate<br/>Capacity Constraint<br/>12/27/2019<br/>03:14:16 PM<br/> <br/><br/>No response required<br/> <br/> <br/>AGT Pipeline Conditions for 12/28/2019<br/></div>']]

Как мне захватить то, что находится между тегами <br/>, включая пробелы, когда между ними ничего нет?

Я должен был добавить, что вывод должен стать списком списков с каждым элементом в отдельности, тегом <br/> является элемент в списке. Например:

[['"006951446", "Algonquin Gas Transmission, LLC", "Critical notice", "12/30/2019", "09:00:00 AM", "12/31/2019", "09:00:00 AM", "92112", "Initiate", "Capacity Constraint", "12/29/2019", "03:02:38 PM", "No response required", "AGT Pipeline Conditions for 12/30/2019"'],
 ['"006951446", "Algonquin Gas Transmission, LLC", "Critical notice", "12/29/2019", "09:00:00 AM", "12/30/2019", "09:00:00 AM", "92086", "Initiate", "Capacity Constraint", "12/28/2019", "02:55:39 PM", "No response required", "AGT Pipeline Conditions for 12/29/2019"'],
 ['"006951446", "Algonquin Gas Transmission, LLC", "Critical notice", "12/28/2019", "09:00:00 AM", "12/29/2019", "09:00:00 AM", "92074", "Initiate", "Capacity Constraint", "12/27/2019", "03:14:16 PM", "No response required", "AGT Pipeline Conditions for 12/28/2019"']]

Answer 1

Обычно, когда вы используете select для объекта BeatifulSoup, вы получаете список Tag s.
И вы можете снова использовать select / getText на Tag s.
Например:

SEP='(--*--SEP--*--)'
mylist=soup.select('div')
between_br=[[j for j in i.getText(SEP).split(SEP) if not j.isspace()] for i in mylist]

Решения с использованием библиотеки SimplifiedDo c.

from simplified_scrapy import SimplifiedDoc,req,utils
mylist = [['<div id="headingData">006951446<br/>Algonquin Gas Transmission, LLC<br/>Critical notice<br/>12/30/2019<br/>09:00:00 AM<br/>12/31/2019<br/>09:00:00 AM<br/>92112<br/>Initiate<br/>Capacity Constraint<br/>12/29/2019<br/>03:02:38 PM<br/> <br/><br/>No response required<br/> <br/> <br/>AGT Pipeline Conditions for 12/30/2019<br/></div>'],
          ['<div id="headingData">006951446<br/>Algonquin Gas Transmission, LLC<br/>Critical notice<br/>12/29/2019<br/>09:00:00 AM<br/>12/30/2019<br/>09:00:00 AM<br/>92086<br/>Initiate<br/>Capacity Constraint<br/>12/28/2019<br/>02:55:39 PM<br/> <br/><br/>No response required<br/> <br/> <br/>AGT Pipeline Conditions for 12/29/2019<br/></div>'],
          ['<div id="headingData">006951446<br/>Algonquin Gas Transmission, LLC<br/>Critical notice<br/>12/28/2019<br/>09:00:00 AM<br/>12/29/2019<br/>09:00:00 AM<br/>92074<br/>Initiate<br/>Capacity Constraint<br/>12/27/2019<br/>03:14:16 PM<br/> <br/><br/>No response required<br/> <br/> <br/>AGT Pipeline Conditions for 12/28/2019<br/></div>']]
values = []
# First way
for item in mylist:
  doc = SimplifiedDoc(item[0])
  tmp = doc.selects('br').nextText()
  tmp.insert(0,doc.div.firstText())
  values.append(tmp)
values = []
# Second way
for item in mylist:
  doc = SimplifiedDoc(item[0])
  brs = doc.selects('br')
  tmp = [br.previousText() for br in brs]
  values.append(tmp)
print(values)

Результат:

[['006951446', 'Algonquin Gas Transmission, LLC', 'Critical notice', '12/30/2019', '09:00:00 AM', '12/31/2019', '09:00:00 AM', '92112', 'Initiate', 'Capacity Constraint', '12/29/2019', '03:02:38 PM', '', '', 'No response required', '', '', 'AGT Pipeline Conditions for 12/30/2019'], ['006951446', 'Algonquin Gas Transmission, LLC', 'Critical notice', '12/29/2019', '09:00:00 AM', '12/30/2019', '09:00:00 AM', '92086', 'Initiate', 'Capacity Constraint', '12/28/2019', '02:55:39 PM', '', '', 'No response required', '', '', 'AGT Pipeline Conditions for 12/29/2019'], ['006951446', 'Algonquin Gas Transmission, LLC', 'Critical notice', '12/28/2019', '09:00:00 AM', '12/29/2019', '09:00:00 AM', '92074', 'Initiate', 'Capacity Constraint', '12/27/2019', '03:14:16 PM', '', '', 'No response required', '', '', 'AGT Pipeline Conditions for 12/28/2019']]

Answer 3

from bs4 import BeautifulSoup
mylist = [['<div id="headingData">006951446<br/>Algonquin Gas Transmission, LLC<br/>Critical notice<br/>12/30/2019<br/>09:00:00 AM<br/>12/31/2019<br/>09:00:00 AM<br/>92112<br/>Initiate<br/>Capacity Constraint<br/>12/29/2019<br/>03:02:38 PM<br/> <br/><br/>No response required<br/> <br/> <br/>AGT Pipeline Conditions for 12/30/2019<br/></div>'],
          ['<div id="headingData">006951446<br/>Algonquin Gas Transmission, LLC<br/>Critical notice<br/>12/29/2019<br/>09:00:00 AM<br/>12/30/2019<br/>09:00:00 AM<br/>92086<br/>Initiate<br/>Capacity Constraint<br/>12/28/2019<br/>02:55:39 PM<br/> <br/><br/>No response required<br/> <br/> <br/>AGT Pipeline Conditions for 12/29/2019<br/></div>'],
          ['<div id="headingData">006951446<br/>Algonquin Gas Transmission, LLC<br/>Critical notice<br/>12/28/2019<br/>09:00:00 AM<br/>12/29/2019<br/>09:00:00 AM<br/>92074<br/>Initiate<br/>Capacity Constraint<br/>12/27/2019<br/>03:14:16 PM<br/> <br/><br/>No response required<br/> <br/> <br/>AGT Pipeline Conditions for 12/28/2019<br/></div>']]

for item in mylist:
    soup = BeautifulSoup(*item, 'html.parser')
    print(*[a.get_text(strip=True, separator="|").split("|") for a in soup])

Выход:

Answer 4

Не видя остальной части вашего кода, может быть трудно дать точный ответ, но beautifulsoup - отличный пакет для этого. Вы сможете продолжить использование пакета bs4, чтобы прочесать HTML, используя комбинацию методов BeautifulSoup (например, find / find_all / select et c.)
