如何使用 beautifulsoup 提取 html？

Question

HTML 来源是

html = """
<td>
 <a href="/urlM5CLw" target="_blank">
  <img alt="I" height="132" src="VZhAy" width="132"/>
 </a>
 <br/>
 <cite title="mac-os-x-lion-icon-pack.en.softonic.com">
  mac-os-x-lion-icon-pac...
 </cite>
 <br/>
 <b>
  Mac
 </b>
 OS X Lion Icon Pack's
 <br/>
 535 × 535 - 135k - png
</td>"""

我的python代码

soup = BeautifulSoup(html)
text = soup.find('td').renderContents()

通过这些代码我可以得到类似

的字符串

<a href="/urlM5CLw" target="_blank"><img alt="I" height="132" src="VZhAy" width="132"/></a><br/><cite title="mac-os-x-lion-icon-pack.en.softonic.com">mac-os-x-lion-icon-pac...</cite><br/><b>Mac</b> OS X Lion Icon Pack's<br/>535 × 535 - 135k - png

但我不要<a>....</a>，我只需要：

<br/><cite title="mac-os-x-lion-icon-pack.en.softonic.com">mac-os-x-lion-icon-pac...</cite><br/><b>Mac</b> OS X Lion Icon Pack's<br/>535 × 535 - 135k - png

Answer 1

尝试删除 <a> 标签，然后获取您想要的内容。

>>> soup.find('a').extract()
>>> text = soup.find('td').renderContents()
>>> text
'<br/><cite title="mac-os-x-lion-icon-pack.en.softonic.com">mac-os-x-lion-icon-pac...</cite><br/><b>Mac</b> OS X Lion Icon Pack's<br/>535 \xd7 535 - 135k - png'

Answer 2

您可以使用 Tag.decompose() method to remove the a tag and completely destroy his contents also you may need to decode() 您的字节字符串并将所有出现的 \n 替换为 '' 。

soup = BeautifulSoup(html, 'lxml')
soup.a.decompose()
print(soup.td.renderContents().decode().replace('\n', ''))

产量：

<br/><cite title="mac-os-x-lion-icon-pack.en.softonic.com">  mac-os-x-lion-icon-pac... </cite><br/><b>  Mac </b> OS X Lion Icon Pack's <br/> 535 × 535 - 135k - png
