对于下面的 HTML 代码，如何使用正则表达式和 Beautiful Soup 以及 Python Requests Library 提取 标签后面的 aaa、bbb
的内容
<html>
<head></head>
<body>
<table style="max-width: 600px; margin: auto;">
<tbody>
<tr>
<td>Swan</td>
<td>Flower</td>
</tr>
<tr>
<td colspan="2" style="background: #ffffff;">
<h5>Playground</h5>
</td>
</tr>
<tr>
<td colspan="2">
<strong>Animal:</strong>
<br>aaa</td>
</tr>
<tr>
<td colspan="2">
<strong>Fish:</strong>
<br>bbb</td>
</tr>
<tr>
<td colspan="2" style="text-align: center;">
<form method="post">
<input type="hidden" name="yyy" value="7777">
<input type="hidden" name="rrr" value="wssss">
<input type="submit" value="djd ddd" style="width: 250px;">
</form>
</td>
</tr>
</tbody>
</table>
</body>
我尝试了下面的代码，但它似乎不起作用
import requests
from bs4 import BeautifulSoup
params = {
'api_key': 'APIKEY',
'custom_cookies': 'PHPSESSID=SESSIONID,domain=DOMAIN.com;',}
response = requests.get(
url='www.example.com',
params=params,
timeout=120,
)
soup = BeautifulSoup(response.content, 'html.parser')
results = soup.find_all('td', {'colspan': '2', 'strong': True})
#Extract the text content from each matching element
for result in results:
br_tag = result.find('br')
if br_tag:
text_content = br_tag.next_sibling.strip()
print(text_content)
预期输出
aaa bb
我得到的输出
[]
尝试：
from bs4 import BeautifulSoup
html_text = """\
<html>
<head></head>
<body>
<table style="max-width: 600px; margin: auto;">
<tbody>
<tr>
<td>Swan</td>
<td>Flower</td>
</tr>
<tr>
<td colspan="2" style="background: #ffffff;">
<h5>Playground</h5>
</td>
</tr>
<tr>
<td colspan="2">
<strong>Animal:</strong>
<br>aaa</td>
</tr>
<tr>
<td colspan="2">
<strong>Fish:</strong>
<br>bbb</td>
</tr>
<tr>
<td colspan="2" style="text-align: center;">
<form method="post">
<input type="hidden" name="yyy" value="7777">
<input type="hidden" name="rrr" value="wssss">
<input type="submit" value="djd ddd" style="width: 250px;">
</form>
</td>
</tr>
</tbody>
</table>
</body>"""
soup = BeautifulSoup(html_text, "html.parser")
for td in soup.select("td:has(strong)"):
text = list(td.stripped_strings)[-1]
print(text)
打印：
aaa
bbb
