BeautifulSoup移除标签 [英] BeautifulSoup removing tags

问题描述

我正在尝试从源代码中删除样式标签及其内容，但是它不起作用，没有错误只是不会分解.这就是我所拥有的:

I'm trying to remove the style tags and their contents from the source, but it's not working, no errors just simply doesn't decompose. This is what I have:

source = BeautifulSoup(open("page.html"))
getbody = source.find('body')
for child in getbody[0].children:
    try:
        if child.get('style') is not None and child.get('style') == "display:none":
            # it in here
            child.decompose()
    except:
        continue
print source
# display:hidden div's are still there.

推荐答案

以下代码可以满足您的需求，并且可以正常工作；除了处理掩盖错误之外，不要不要使用橡皮布:

The following code does what you want and works fine; do not use blanket except handling to mask bugs:

source = BeautifulSoup(open("page.html"))
for hidden in source.body.find_all(style='display:none'):
    hidden.decompose()

或更妙的是，使用正则表达式将网络投射得更宽:

or better still, use a regular expression to cast the net a little wider:

import re

source = BeautifulSoup(open("page.html"))
for hidden in source.body.find_all(style=re.compile(r'display:\s*none')):
    hidden.decompose()

Tag.children 仅列出 body 标签的 direct 个子级，而不是所有嵌套的子级.

Tag.children only lists direct children of the body tag, not all nested children.
