Question

这是我到目前为止所做的：

from bs4 import BeautifulSoup

def cleanme(html):
    soup = BeautifulSoup(html) # create a new bs4 object from the html data loaded
    for script in soup(["script"]): 
        script.extract()
    text = soup.get_text()
    return text
testhtml = "<!DOCTYPE HTML>\n<head>\n<title>THIS IS AN EXAMPLE </title><style>.call {font-family:Arial;}</style><script>getit</script><body>I need this text captured<h1>And this</h1></body>"

cleaned = cleanme(testhtml)
print (cleaned)

这是为了删除脚本

Answer 1

看起来你几乎拥有它。您还需要删除html标记和CSS样式代码。这是我的解决方案（我更新了函数）：

def cleanMe(html):
    soup = BeautifulSoup(html) # create a new bs4 object from the html data loaded
    for script in soup(["script", "style"]): # remove all javascript and stylesheet code
        script.extract()
    # get text
    text = soup.get_text()
    # break into lines and remove leading and trailing space on each
    lines = (line.strip() for line in text.splitlines())
    # break multi-headlines into a line each
    chunks = (phrase.strip() for line in lines for phrase in line.split("  "))
    # drop blank lines
    text = '\n'.join(chunk for chunk in chunks if chunk)
    return text

Answer 2

您可以使用decompose从文档和stripped_strings生成器中完全删除标记，以检索标记内容。

def clean_me(html):
    soup = BeautifulSoup(html)
    for s in soup(['script', 'style']):
        s.decompose()
    return ' '.join(soup.stripped_strings)

>>> clean_me(testhtml) 
'THIS IS AN EXAMPLE I need this text captured And this'

Answer 3

Removing specified tags and comments in a clean manner. Thanks to Kim Hyesung for this code.

from bs4 import BeautifulSoup
from bs4 import Comment

def cleanMe(html):
    soup = BeautifulSoup(html, "html5lib")    
    [x.extract() for x in soup.find_all('script')]
    [x.extract() for x in soup.find_all('style')]
    [x.extract() for x in soup.find_all('meta')]
    [x.extract() for x in soup.find_all('noscript')]
    [x.extract() for x in soup.find_all(text=lambda text:isinstance(text, Comment))]
    return soup

Answer 4

如果你想要一个快速而肮脏的解决方案，你可以使用：

re.sub(r'<[^>]*?>', '', value)

在php中创建等效的strip_tags。这就是你想要的吗？

Answer 5

改为使用lxml：

# Requirements: pip install lxml

import lxml.html.clean


def cleanme(content):
    cleaner = lxml.html.clean.Cleaner(
        allow_tags=[''],
        remove_unknown_tags=False,
        style=True,
    )
    html = lxml.html.document_fromstring(content)
    html_clean = cleaner.clean_html(html)
    return html_clean.text_content().strip()

testhtml = "<!DOCTYPE HTML>\n<head>\n<title>THIS IS AN EXAMPLE </title><style>.call {font-family:Arial;}</style><script>getit</script><body>I need this text captured<h1>And this</h1></body>"
cleaned = cleanme(testhtml)
print (cleaned)

从html页面中删除所有样式，脚本和html标记
