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
