asp常用的正则表达式实现字符串的替换,主要包括去除html标签，去除class标签和去除script标签等 去除html标签正则<\/*[^<>]*>
Function LoseHtml(ContentStr)
Dim ClsTempLoseStr,RegEx
ClsTempLoseStr = Cstr(ContentStr)
Set RegEx = New RegExp
RegEx.Pattern = "<\/*[^<>]*>"
RegEx.IgnoreCase = True
RegEx.Global = True
ClsTempLoseStr = RegEx.Replace(ClsTempLoseStr,"")
Set RegEx = Nothing
LoseHtml = ClsTempLoseStr
End function
