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()

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

html2text是一个Python程序，它在这方面做得很好。

我推荐一个名为goose-extractor的Python包 Goose将尝试提取以下信息:

文章的正文 文章主图 任何Youtube/Vimeo电影嵌入文章 元数据描述 元标记

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。

另一种选择是通过基于文本的web浏览器运行html并转储它。例如(使用Lynx):

lynx -dump html_to_convert.html > converted_html.txt

这可以在python脚本中完成，如下所示:

import subprocess

with open('converted_html.txt', 'w') as outputFile:
    subprocess.call(['lynx', '-dump', 'html_to_convert.html'], stdout=testFile)

它不会精确地为您提供HTML文件中的文本，但根据您的用例，它可能比html2text的输出更好。
