python实现html转ubb代码(html2ubb)

import re
def Html2UBB(content):
	#以下是将html标签转为ubb标签
	pattern = re.compile( ‘<a href=\"([sS]+?)\"[^>]*>([sS]+?)</a>‘,re.I)
	content = pattern.sub(r‘[url=1]2[/url]‘,content)
	pattern = re.compile( ‘<img[^>]+src=\"([^\"]+)\"[^>]*>‘,re.I)
	content = pattern.sub(r‘[img]1[/img]‘,content)
	pattern = re.compile( ‘<strong>([sS]+?)</strong>‘,re.I)
	content = pattern.sub(r‘[b]1[/b]‘,content)
	pattern = re.compile( ‘<font color=\"([sS]+?)\">([sS]+?)</font>‘,re.I)
	content = pattern.sub(r‘[1]2[/1]‘,content)
	pattern = re.compile( ‘<[^>]*?>‘,re.I)
	content = pattern.sub(‘‘,content)
	#以下是将html转义字符转为普通字符
	content = content.replace(‘<‘,‘<‘)
	content = content.replace(‘>‘,‘>‘)
	content = content.replace(‘”‘,‘”‘)
	content = content.replace(‘“‘,‘“‘)
	content = content.replace(‘"‘,‘"‘)
	content = content.replace(‘©‘,‘©‘)
	content = content.replace(‘®‘,‘®‘)
	content = content.replace(‘ ‘,‘ ‘)
	content = content.replace(‘—‘,‘—‘)
	content = content.replace(‘–‘,‘–‘)
	content = content.replace(‘‹‘,‘‹‘)
	content = content.replace(‘›‘,‘›‘)
	content = content.replace(‘…‘,‘…‘)
	content = content.replace(‘&‘,‘&‘)
	return content
