Python版html_entity_decode(text):

code过程中需要Convert all HTML entities to their applicable characters

google了一下，发现PHP有现成的函数

string html_entity_decode ( string $string [, int $quote_style = ENT_COMPAT [, string $charset ]] )，

而自己正在使用修改python程序，因而写了python版的同样的方法：

def html_entity_decode(text):

052

"""

053	Removes HTML or XML character references and entities from a text string.

054

055	@param text The HTML (or XML) source text.

056	@return The plain text, as a Unicode string, if necessary.

057

"""

058	import re, htmlentitydefs

059	def fixup(m):

060	text = m.group( 0 )

061	if text[: 2 ] = = "&#" :

062	# character reference

063

try :

064	if text[: 3 ] = = "&#x" :

065	return unichr ( int (text[ 3 : - 1 ], 16 ))

066

else :

067	return unichr ( int (text[ 2 : - 1 ]))

068	except ValueError:

069

pass

070

else :

071	# named entity

072

try :

073	text = unichr (htmlentitydefs.name2codepoint[text[ 1 : - 1 ]])

074	except KeyError:

075

pass

076	return text # leave as is

077	return re.sub( "&#?/w+;" , fixup, text)
