使用 BeautifulSoup 标记后无法立即获取文本

Question

Currently, in my code I break down a larger soup to get all the 'td' tags with this code:

floorplans_all = sub_soup.findAll('td', {"data-label":"Rent"})
floorplan_soup = soup(floorplans_all[0].prettify(), "html.parser")
rent_span = floorplan_soup.findAll('span', {"class":"sr-only"})

print(floorplans_all)

and end up with the following:

<td data-label="Rent" data-selenium-id="Rent_6">
    <span class="sr-only">
      Monthly Rent
     </span>
     $2,335 -
     <span class="sr-only">
      to
     </span>
     $5,269
    </td>

Printing rent_span looks like this:

  [<span class="sr-only">
  Monthly Rent
 </span>, <span class="sr-only">
  to
 </span>]

I can't seem to get "$2,335 -" and "$5,269" from above. I have been trying to walk down the HTML tree, but I'm not able to get the text between the tags.

Answer 1

The td element has five children:

• A text node containing only whitespace
• A span node containing “Monthly Rent”
• A text node containing “$2,335 -”
• A span node containing “to”
• A text node containing “$5,269”

You can iterate those children by using the children attribute:

soup = BeautifulSoup(text, 'html.parser')

for child in soup.td.children:
    print(repr(child))

'\n'
<span class="sr-only">
      Monthly Rent
     </span>
'\n     $2,335 -\n     '
<span class="sr-only">
      to
     </span>
'\n     $5,269\n    '

If you want to explicitly look for the text nodes, you could search for the span nodes and get the next sibling each time:

>>> [span.next_sibling.string.strip() for span in soup.td.find_all(class_='sr-only')]
['$2,335 -', '$5,269']

Answer 2

soup = BeautifulSoup(res, 'html.parser')

row = soup.find('td', {'data-label': "Rent"})
for all in row.find_all('span'):
    print(all.text.strip())

an output will be look like this

Monthly Rent
$2,335
 $5,269
