Jos*_*eph 11 html python comments beautifulsoup bs4
四年前就提出了这个问题,但现在BS4的答案已经过时了.
我想用漂亮的汤删除我的html文件中的所有评论.由于BS4将每个注释作为一种特殊类型的可导航字符串,我认为这段代码可以工作:
for comments in soup.find_all('comment'):
comments.decompose()
所以这不起作用....如何使用BS4找到所有评论？

您可以将函数传递给find_all()以帮助它检查字符串是否为Comment.
例如我在html下面:
<body>
<!-- Branding and main navigation -->
<div class="Branding">The Science & Safety Behind Your Favorite Products</div>
<div class="l-branding">
<p>Just a brand</p>
</div>
<!-- test comment here -->
<div class="block_content">
<a href="https://www.google.com">Google</a>
</div>
</body>
码:
from bs4 import BeautifulSoup as BS
from bs4 import Comment
....
soup = BS(html, 'html.parser')
comments = soup.find_all(string=lambda text: isinstance(text, Comment))
for c in comments:
print(c)
print("===========")
c.extract()
输出将是:
Branding and main navigation
============
test comment here
============
顺便说一句,我认为之所以find_all('Comment')不起作用(来自BeautifulSoup文档):
传递一个名称的值,你会告诉Beautiful Soup只考虑具有某些名称的标签.将忽略文本字符串,名称不匹配的标记也将被忽略.

我需要做的两件事:
首先,当导入美丽的汤
from bs4 import BeautifulSoup, Comment
其次,这是提取注释的代码
for comments in soup.findAll(text=lambda text:isinstance(text, Comment)):
comments.extract()
