从HTML表的每一行中抓取每个元素

from bs4 import BeautifulSoup

# 假设HTML代码存储在html变量中
html = '''
<table>
  <tr>
    <td>John</td>
    <td>Doe</td>
    <td>john@example.com</td>
  </tr>
  <tr>
    <td>Jane</td>
    <td>Smith</td>
    <td>jane@example.com</td>
  </tr>
</table>
'''

# 创建BeautifulSoup对象
soup = BeautifulSoup(html, 'html.parser')

# 定位表格元素
table = soup.find('table')

# 遍历每一行
for row in table.find_all('tr'):
    # 遍历每个元素
    for cell in row.find_all('td'):
        # 打印元素值
        print(cell.text)

John
Doe
john@example.com
Jane
Smith
jane@example.com
