    public string wipeScript(string html)
    {
        System.Text.RegularExpressions.Regex regex1 = new System.Text.RegularExpressions.Regex(@"<script[/s/S]+</script *>", System.Text.RegularExpressions.RegexOptions.IgnoreCase);

        html = regex1.Replace(html, ""); //过滤<script></script>标记
        html = regex2.Replace(html, ""); //过滤href=javascript: (<A>) 属性
        html = regex3.Replace(html, " _disibledevent="); //过滤其它控件的on...事件
        html = regex4.Replace(html, ""); //过滤iframe
