python - 在python中解码html编码的字符串

Question

我有以下字符串...

"Scam, hoax, or the real deal, he’s gonna work his way to the bottom of the sordid tale, and hopefully end up with an arcade game in the process."

我需要把它变成这个字符串...

Scam, hoax, or the real deal, he’s gonna work his way to the bottom of the sordid tale, and hopefully end up with an arcade game in the process.

这是非常标准的 HTML 编码，我一辈子都想不出如何在 python 中转换它。

我发现了这个: GitHub

它非常接近工作，但是它不输出撇号而是输出一些非 unicode 字符。

这是 GitHub 脚本的输出示例...

Scam, hoax, or the real deal, heâs gonna work his way to the bottom of the sordid tale, and hopefully end up with an arcade game in the process.

您正在尝试做的事情称为“HTML 实体解码”，它在过去的许多 Stack Overflow 问题中都有涉及，例如:

• How to unescape apostrophes and such in Python?
• Decoding HTML Entities With Python

这是使用 Beautiful Soup 的代码片段用于解码您的示例的 HTML 解析库:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from BeautifulSoup import BeautifulSoup

string = "Scam, hoax, or the real deal, he’s gonna work his way to the bottom of the sordid tale, and hopefully end up with an arcade game in the process."
s = BeautifulSoup(string,convertEntities=BeautifulSoup.HTML_ENTITIES).contents[0]
print s

这是输出:

Scam, hoax, or the real deal, he’s gonna work his way to the bottom of the sordid tale, and hopefully end up with an arcade game in the process.
