Js将html转成UBB

HTML代码如下：
<div class="a">
<div class="b">引用</div>
                 1
<div class="c">
   <div class="a">
                      <div class="b">引用</div>
              <div class="c">2</div>
   </div>
</div>
</div>我已经写出了
   <div class="a">
                      <div class="b">引用</div>
              <div class="c">1</div>
   </div>
的正则，请问怎么把前面的html代码替换成UBB：
的格式？
要求能解析多重嵌套，不只两层

ls的，我问的是html转ubb~~ thank you all the same
哦...看反了... function pattern(str){
//str = str.replace(/(\r\n|\n|\r)/ig, '');
str = str.replace(/<br[^>]*>/ig,'\n');
str = str.replace(/<p[^>\/]*\/>/ig,'\n');
//str = str.replace(/\[code\](.+?)\[\/code\]/ig, function($1, $2) {return phpcode($2);});
str = str.replace(/\son[\w]{3,16}\s?=\s*([\'\"]).+?\1/ig,''); str = str.replace(/<hr[^>]*>/ig,'[hr]');
str = str.replace(/<(sub|sup|u|strike|b|i|pre)>/ig,'[$1]');
str = str.replace(/<\/(sub|sup|u|strike|b|i|pre)>/ig,'[/$1]');
str = str.replace(/<(\/)?strong>/ig,'[$1b]');
str = str.replace(/<(\/)?em>/ig,'[$1i]');
str = str.replace(/<(\/)?blockquote([^>]*)>/ig,'[$1blockquote]'); str = str.replace(/<img[^>]*smile=\"(\d+)\"[^>]*>/ig,'[s:$1]');
str = str.replace(/<img[^>]*src=[\'\"\s]*([^\s\'\"]+)[^>]*>/ig,'');
str = str.replace(/<a[^>]*href=[\'\"\s]*([^\s\'\"]*)[^>]*>(.+?)<\/a>/ig,''+'$2'+'');
//str = str.replace(/<h([1-6]+)([^>]*)>(.*?)<\/h\1>/ig,function($1,$2,$3,$4){return h($3,$4,$2);}); str = str.replace(/<[^>]*?>/ig, '');
str = str.replace(/&/ig, '&');
str = str.replace(/</ig, '<');
str = str.replace(/>/ig, '>'); return str;
}
function htmltoubb(){
str = pattern(document.getElementById("htmlsource").value);
document.getElementById("ubbresult").value=str;
}

你就不能让我懒一下吗...
// 没有测试过
var reg = /<div class="a">\s*<div class="b">引用<\/div>\s*<div class="c">\s*((?:(?!<div class="a">)[\d\D])*?)\s*<\/div>\s*<\/div>/;
while (reg.test(str)) {
str = str.replace(reg, "");
