这是我对python 3的解决方案。

import html
import re

def html_to_txt(html_text):
    ## unescape html
    txt = html.unescape(html_text)
    tags = re.findall("<[^>]+>",txt)
    print("found tags: ")
    print(tags)
    for tag in tags:
        txt=txt.replace(tag,'')
    return txt

不确定它是否完美，但解决了我的用例，看起来很简单。

我正在解析Github自述，我发现下面的工作真的很好:

import re
import lxml.html

def strip_markdown(x):
    links_sub = re.sub(r'\[(.+)\]\([^\)]+\)', r'\1', x)
    bold_sub = re.sub(r'\*\*([^*]+)\*\*', r'\1', links_sub)
    emph_sub = re.sub(r'\*([^*]+)\*', r'\1', bold_sub)
    return emph_sub

def strip_html(x):
    return lxml.html.fromstring(x).text_content() if x else ''

然后

readme = """<img src="https://raw.githubusercontent.com/kootenpv/sky/master/resources/skylogo.png" />

            sky is a web scraping framework, implemented with the latest python versions in mind (3.4+). 
            It uses the asynchronous `asyncio` framework, as well as many popular modules 
            and extensions.

            Most importantly, it aims for **next generation** web crawling where machine intelligence 
            is used to speed up the development/maintainance/reliability of crawling.

            It mainly does this by considering the user to be interested in content 
            from *domains*, not just a collection of *single pages*
            ([templating approach](#templating-approach))."""

strip_markdown(strip_html(readme))

正确移除所有markdown和html。

import re

def remove(text):
    clean = re.compile('<.*?>')
    return re.sub(clean, '', text)

简单的代码!这将删除其中的所有类型的标签和内容。

def rm(s):
    start=False
    end=False
    s=' '+s
    for i in range(len(s)-1):
        if i<len(s):
            if start!=False:
                if s[i]=='>':
                    end=i
                    s=s[:start]+s[end+1:]
                    start=end=False
            else:
                if s[i]=='<':
                    start=i
    if s.count('<')>0:
        self.rm(s)
    else:
        s=s.replace('&nbsp;', ' ')
        return s

但如果文本中包含<>符号，则不会给出完整结果。

python 3改编自søren-løvborg的回答

from html.parser import HTMLParser
from html.entities import html5

class HTMLTextExtractor(HTMLParser):
    """ Adaption of http://stackoverflow.com/a/7778368/196732 """
    def __init__(self):
        super().__init__()
        self.result = []

    def handle_data(self, d):
        self.result.append(d)

    def handle_charref(self, number):
        codepoint = int(number[1:], 16) if number[0] in (u'x', u'X') else int(number)
        self.result.append(unichr(codepoint))

    def handle_entityref(self, name):

    s.feed(html)
    return s.get_text()

对于一个项目，我需要这样剥离HTML，但也css和js。因此，我对eloff的回答做了一个变化:

class MLStripper(HTMLParser):
    def __init__(self):
        self.reset()
        self.strict = False
        self.convert_charrefs= True
        self.fed = []
        self.css = False
    def handle_starttag(self, tag, attrs):
        if tag == "style" or tag=="script":
            self.css = True
    def handle_endtag(self, tag):
        if tag=="style" or tag=="script":
            self.css=False
    def handle_data(self, d):
        if not self.css:
            self.fed.append(d)
    def get_data(self):
        return ''.join(self.fed)

def strip_tags(html):
    s = MLStripper()
    s.feed(html)
    return s.get_data()
