Jui*_*icy 7 html python beautifulsoup
很多问题在这里有类似的标题,但我试图从汤对象本身删除标签.
我有一个页面,其中包含div:
<div id="content">
I want to keep this<br /><div id="blah">I want to remove this</div>
</div>
我可以选择<div id="content">,soup.find('div', id='content')但我想删除<div id="blah">它.

extract如果要从树中删除标记或字符串,可以使用.
In [13]: soup = BeautifulSoup("""<div id="content">
I want to keep this<br /><div id="blah">I want to remove this</div>
</div>""")
In [14]: soup = BeautifulSoup("""<div id="content">
....: I want to keep this<br /><div id="blah">I want to remove this</div>
....: </div>""")
In [15]: blah = soup.find(id='blah')
In [16]: _ = blah.extract()
In [17]: soup
Out[17]:
<html><body><div id="content">
I want to keep this<br/>
</div></body></html>
该Tag.decompose方法tag从树中删除.所以找到div标签:
div = soup.find('div', {'id':'content'})
循环所有的孩子,但第一个:
for child in list(div)[1:]:
并尝试分解孩子们:
try:
child.decompose()
except AttributeError: pass
import bs4 as bs
content = '''<div id="content">
I want to keep this<br /><div id="blah">I want to remove this</div>
</div>'''
soup = bs.BeautifulSoup(content)
div = soup.find('div', {'id':'content'})
for child in list(div)[1:]:
try:
child.decompose()
except AttributeError: pass
print(div)
产量
<div id="content">
I want to keep this
</div>
使用lxml的等价物将是
import lxml.html as LH
content = '''<div id="content">
I want to keep this<br /><div id="blah">I want to remove this</div>
</div>'''
root = LH.fromstring(content)
div = root.xpath('//div[@id="content"]')[0]
for child in div:
div.remove(child)
print(LH.tostring(div))
