example:

           StringBuilder sbXml = new StringBuilder();
            StringWriter sw = new StringWriter(sbXml);
            XmlTextWriter tw = new XmlTextWriter(sw);
            HtmlWeb htmlWeb = new HtmlWeb();
            htmlWeb.LoadHtmlAsXml("http://finance.qq.com/a/20121126/000974.htm", tw);
            richTextBox1.Text = sbXml.ToString();
