请问如何在T－sql中运用正则过滤HTML代码

public string ScriptHtml(string HtmlStr)
    {
        string[] aryReg = {
            @"<script[^>]*?>.*?</script>",
            @"<(\/\s*)?!?((\w+:)?\w+)(\w+(\s*=?\s*(([""'])(\\[""'tbnr]|[^\7])*?\7|\w+)|.{0})|\s)*?(\/\s*)?>",
            @"([\r\n])[\s]+",
            @"&(quot|#34);",
            @"&(amp|#38);",
            @"&(lt|#60);",
            @"&(gt|#62);", 
            @"&(nbsp|#160);", 
            @"&(iexcl|#161);",
            @"&(cent|#162);",
            @"&(pound|#163);",
            @"&(copy|#169);",
            @"&#(\d+);",
            @"-->",
            @"<!--.*\n"
        };        string[] aryRep = {
            "",
            "",
            "",
            "\"",
            "&",
            "<",
            ">",
            " ",
            "\xa1",//chr(161),
            "\xa2",//chr(162),
            "\xa3",//chr(163),
            "\xa9",//chr(169),
            "",
            "\r\n",
            ""
        };
        string newReg = aryReg[0];        string strOutput = HtmlStr;        for (int i = 0; i < aryReg.Length; i++)
        {            Regex regex = new Regex(aryReg[i], RegexOptions.IgnoreCase);            strOutput = regex.Replace(strOutput, aryRep[i]);        }        strOutput.Replace("<", "");        strOutput.Replace(">", "");        strOutput.Replace("\r\n", "");        return strOutput;
    }这是一段C#的代码
我想吧这个过程写在存储过程中完成
请各位大虾帮忙
