我正在尝试使用 beautifulsoup 从表行中获取字符串。我想要获取的字符串是第二行和第三行的“SANDAL”和“SHORTS”。我知道这可以用正则表达式或字符串函数来解决，但我想学习 beautifulsoup 并尽可能多地使用 beautifulsoup。截取的 python 代码 soup=beautifulsoup(page,'html.parser') table=soup.find('table') row=table.find_next('tr') row=row.find_next('tr')HTML <html> <body> <div id="body"> <div class="data"> <table id="products"> <tr><td>PRODUCT<td class="ole1">ID<td class="c1">TYPE<td class="ole1">WHEN<td class="ole4">ID<td class="ole4">ID</td></tr> <tr><td>SANDAL<td class="ole1">77313<td class="ole1">wear<td class="ole1">new<td class="ole4">id<td class="ole4">878717</td></tr> <tr><td>SHORTS<td class="ole1">77314<td class="ole1">wear<td class="ole1">new<td class="ole4">id<td class="ole4">878718</td></tr> </table> </div> </div> </body> </html>

要从表格的第一列（无标题）获取文本，您可以使用此脚本：
from bs4 import BeautifulSoup
txt = '''
<html>
<body>
<div id="body">
<div class="data">
<table id="products">
<tr><td>PRODUCT<td class="ole1">ID<td class="c1">TYPE<td class="ole1">WHEN<td class="ole4">ID<td class="ole4">ID</td></tr>
<tr><td>SANDAL<td class="ole1">77313<td class="ole1">wear<td class="ole1">new<td class="ole4">id<td class="ole4">878717</td></tr>
<tr><td>SHORTS<td class="ole1">77314<td class="ole1">wear<td class="ole1">new<td class="ole4">id<td class="ole4">878718</td></tr>
</table>
</div>
</div>
</body>
</html>'''
soup = BeautifulSoup(txt, 'lxml') # <-- lxml is important here (to parse the HTML code correctly)
for tr in soup.find('table', id='products').find_all('tr')[1:]: # <-- [1:] because we want to skip the header
print(tr.td.text) # <-- print contents of first <td> tag
印刷：
SANDAL
SHORTS
