在Python字符串中解码HTML实体？

问题描述

我使用Beautiful Soup 3解析了一些HTML，但它包含了HTML 3的实体，它不会自动为我解码：

 >>>来自BeautifulSoup import BeautifulSoup 
 
>>>汤= BeautifulSoup（< p> 682m< / p>）
>>> text = soup.find（p）。string 
 
>>>打印文本
& bound; 682m 
  

如何解码 text 得到682m而不是& pound; 682m

解决方案

Python 3.4 +

<$ c不推荐使用$ c> HTMLParser.unescape ，，尽管它被误保留了。它将很快从语言中删除。而是使用 html.unescape（）：

  import html 
 print（html.unescape（'& pound; 682m'））

Python 2.6-3.3

您可以使用标准库中的HTML解析器：

 >>>尝试：
 ...＃Python 2.6-2.7 
 ...从HTMLParser导入HTMLParser 
 ...除ImportError：
 ...＃Python 3 
。 .. from html.parser import HTMLParser 
 ... 
>>> h = HTMLParser（）
>>> print（h.unescape（'& pound; 682m'））
£682m 
  

请参阅兼容库来简化导入：

 >>> from six.moves.html_parser import HTMLParser 
>>> h = HTMLParser（）
>>> print（h.unescape（'& pound; 682m'））
£682m 
  

I'm parsing some HTML with Beautiful Soup 3, but it contains HTML entities which Beautiful Soup 3 doesn't automatically decode for me:

>>> from BeautifulSoup import BeautifulSoup

>>> soup = BeautifulSoup("<p>&pound;682m</p>")
>>> text = soup.find("p").string

>>> print text
&pound;682m

How can I decode the HTML entities in text to get "£682m" instead of "£682m".

解决方案

Python 3.4+

HTMLParser.unescape is deprecated, and was supposed to be removed in 3.5, although it was left in by mistake. It will be removed from the language soon. Instead, use html.unescape():

import html
print(html.unescape('£682m'))

see https://docs.python.org/3/library/html.html#html.unescape

Python 2.6-3.3

You can use the HTML parser from the standard library:

>>> try:
...     # Python 2.6-2.7
...     from HTMLParser import HTMLParser
... except ImportError:
...     # Python 3
...     from html.parser import HTMLParser
...
>>> h = HTMLParser()
>>> print(h.unescape('£682m'))
£682m

See http://docs.python.org/2/library/htmlparser.html

You can also use the six compatibility library to simplify the import:

>>> from six.moves.html_parser import HTMLParser
>>> h = HTMLParser()
>>> print(h.unescape('£682m'))
£682m
