python实现html转ubb代码(html2ubb)

这两天在用python/' target='_blank'>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 redef 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('&lt;','<')content = content.replace('&gt;','>')content = content.replace('&rdquo;','”')content = content.replace('&ldquo;','“')content = content.replace('&quot;','"')content = content.replace('&copy;','©')content = content.replace('&reg;','®')content = content.replace('&nbsp;',' ')content = content.replace('&mdash;','—')content = content.replace('&ndash;','–')content = content.replace('&lsaquo;','‹')content = content.replace('&rsaquo;','›')content = content.replace('&hellip;','…')content = content.replace('&amp;','&')return content

使用时直接调用Html2UBB函数，返回值就是ubb码了html转ubb
