Beautiful soup可以转换html实体。考虑到HTML经常有bug并且充满unicode和HTML编码问题，这可能是您最好的选择。这是我用来将html转换为原始文本的代码:

import BeautifulSoup
def getsoup(data, to_unicode=False):
    data = data.replace(" ", " ")
    # Fixes for bad markup I've seen in the wild.  Remove if not applicable.
    masssage_bad_comments = [
        (re.compile('<!-([^-])'), lambda match: '<!--' + match.group(1)),
        (re.compile('<!WWWAnswer T[=\w\d\s]*>'), lambda match: '<!--' + match.group(0) + '-->'),
    ]
    myNewMassage = copy.copy(BeautifulSoup.BeautifulSoup.MARKUP_MASSAGE)
    myNewMassage.extend(masssage_bad_comments)
    return BeautifulSoup.BeautifulSoup(data, markupMassage=myNewMassage,
        convertEntities=BeautifulSoup.BeautifulSoup.ALL_ENTITIES 
                    if to_unicode else None)

remove_html = lambda c: getsoup(c, to_unicode=True).getText(separator=u' ') if c else ""

html2text是一个Python程序，它在这方面做得很好。

下面是xperroni回答的一个版本，它更完整一些。它跳过脚本和样式部分，并翻译charref(例如，')和HTML实体(例如，&)。

它还包括一个简单的纯文本到html的反向转换器。

如果您需要更高的速度和更低的准确性，那么您可以使用原始lxml。

import lxml.html as lh
from lxml.html.clean import clean_html

def lxml_to_text(html):
    doc = lh.fromstring(html)
    doc = clean_html(doc)
    return doc.text_content()

@PeYoTIL使用BeautifulSoup并删除样式和脚本内容的回答对我来说并不管用。我尝试用分解代替提取，但它仍然没有工作。所以我创建了自己的格式文本使用<p>标签和替换<a>标签与href链接。也处理文本内的链接。可在此主旨与测试文档嵌入。

from bs4 import BeautifulSoup, NavigableString

def html_to_text(html):
    "Creates a formatted text email message as a string from a rendered html template (page)"
    soup = BeautifulSoup(html, 'html.parser')
    # Ignore anything in head
    body, text = soup.body, []
    for element in body.descendants:
        # We use type and not isinstance since comments, cdata, etc are subclasses that we don't want
        if type(element) == NavigableString:
            # We use the assumption that other tags can't be inside a script or style
            if element.parent.name in ('script', 'style'):
                continue

            # remove any multiple and leading/trailing whitespace
            string = ' '.join(element.string.split())
            if string:
                if element.parent.name == 'a':
                    a_tag = element.parent
                    # replace link text with the link
                    string = a_tag['href']
                    # concatenate with any non-empty immediately previous string
                    if (    type(a_tag.previous_sibling) == NavigableString and
                            a_tag.previous_sibling.string.strip() ):
                        text[-1] = text[-1] + ' ' + string
                        continue
                elif element.previous_sibling and element.previous_sibling.name == 'a':
                    text[-1] = text[-1] + ' ' + string
                    continue
                elif element.parent.name == 'p':
                    # Add extra paragraph formatting newline
                    string = '\n' + string
                text += [string]
    doc = '\n'.join(text)
    return doc

我发现的最好的一段代码提取文本没有javascript或不想要的东西:

from urllib.request import urlopen
from bs4 import BeautifulSoup

url = "http://news.bbc.co.uk/2/hi/health/2284783.stm"
html = urlopen(url).read()
soup = BeautifulSoup(html, features="html.parser")

# kill all script and style elements
for script in soup(["script", "style"]):
    script.extract()    # rip it out

# 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)

print(text)

你只需要安装BeautifulSoup:

pip install beautifulsoup4
