这段代码将用户输入的ubb代码转化为html格式，注意，需要Script Engine 5.0的支持(使用了RegExp对象)
注：pattern中使用()将知道regexp记忆搜索到的值，$1是第一个()，其余类推。但$2的语法并不被5.0版本的vbscript.dll所支持，我检查了自己机器上的版本（安装过ie 5.5)，发现vbscript.dll的版本为5.50.4629，最后修改日期为12月25日。该版本支持$1之类的语法，这个简单的改进使regexp的功能逐渐与perl的正则表达式靠近
function UBBCode(strContent)
dim objRegExp
Set objRegExp=new RegExp
objRegExp.IgnoreCase =true
objRegExp.Global=True
'url
objRegExp.Pattern="(\[URL\])(http:\/\/\S+?)(\[\/URL\])"
strContent= objRegExp.Replace(strContent,"<A HREF=""$2""
TARGET=_blank>$2</A>")
objRegExp.Pattern="(\[URL\])(\S+?)(\[\/URL\])"
strContent= objRegExp.Replace(strContent,"<A HREF=""http://$2""
TARGET=_blank>$2</A>")
'email
objRegExp.Pattern="(\[EMAIL\])(\S+\@\S+?)(\[\/EMAIL\])"
strContent= objRegExp.Replace(strContent,"<A
HREF=""mailto:$2"">$2</A>")
objRegExp.Pattern="(\[IMG\])(\S+?)(\[\/IMG\])"
strContent=objRegExp.Replace(strContent,"<IMG SRC=""$2"">")
