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
