所以我一直在为我的公司网站制作一个抓取程序，但是我遇到了一个问题，基本上我需要从html表中删除测试但是我无法获取所需的数据。
HTML CODE
<div>
<table class="style3" cellspacing="0" rules="all" border="1" id="ctl00_cpMainContent_gvNodes" style="border-color:White;border-style:None;width:1090px;border-collapse:collapse;">
<tr>
<th scope="col">History</th>
</tr><tr>
<td style="color:White;background-color:White;font-size:11pt;font-weight:bold;"> </td>
</tr><tr>

我需要能够在br标签内抓取数据，例如附加到第三个td标签的数据，我已经设法从表中获取所有数据但是无法弄清楚如何获取特定行然后获取这些内容在br标签
CODE SNIPPET
bsobjswap = BeautifulSoup(r2.content)
print (bsobjswap.find('table',{'id':'ctl00_cpMainContent_gvNodes'}).find("style",{"color":"Black"}))
这是我最近的尝试，但不起作用。任何帮助表示赞赏

As installation have been done recently, Lancom uses 2.05 configuration script. Our engineer was unable to see landing page, he was getting connected to the Internet with. I contacted Picopoint who informed me that this is due the fact that their system remembers MAC addresses of the devices that were logged into the system hence no landing page is needed. It have been confirmed by removing MAC addresses of the engineer's devices from the database. By doing so engineer was able to access the landing page again. Picopoint's engineer checked the configuration of the devices at both ends and haven't detected any problems.

我的代码访问了数千个页面并查看它，每个表遵循相同的模式，我猜我将始终需要来自第三个td标记的数据，但不知道如何获取它。
干杯
答案 0 :(得分：0)
这个怎么样：
from bs4 import BeautifulSoup
html = """(your html from the example above)"""
soup = BeautifulSoup(html, 'html.parser')
row_data = soup.find('td', {'style':'color:Black;background-color:LightSkyBlue;border-color:LightSkyBlue;font-size:12pt;font-weight:normal;'})
clean_data = str(row_data).replace('<td style="color:Black;background-color:LightSkyBlue;border-color:LightSkyBlue;font-size:12pt;font-weight:normal;">','')\
.replace('</td>','')
print('\n'.join([x for x in clean_data.split('<br/>') if x != '']))
"""
Generated output:
