python实现html转ubb代码(html2ubb)

这两天在用python写一个采集器，有个功能模块是html代码转换为ubb，网上貌似没有现成程序，就自己写了个函数，顺便锻炼下自己的正则。

import re
def Html2UBB(content):
	#以下是将html标签转为ubb标签
	pattern = re.compile( \']*>([sS]+?)\',re.I)
	content = pattern.sub(r\'[url=1]2[/url]\',content)
	pattern = re.compile( \']+src=\\\"([^\\\"]+)\\\"[^>]*>\',re.I)
	content = pattern.sub(r\'[img]1[/img]\',content)
	pattern = re.compile( \'([sS]+?)\',re.I)
	content = pattern.sub(r\'[b]1[/b]\',content)
	pattern = re.compile( \'([sS]+?)\',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

使用时直接调用Html2UBB函数，返回值就是ubb码了html转ubb
