先来个原理简示,有空再补个分解式的类

foreach (XmlElement birthday in dom.DocumentElement.ChildNodes)
            {
                //读取数据 
                if (birthday.SelectSingleNode("fpdm") != null)
                    fpdm = birthday.SelectSingleNode("fpdm").InnerText;
                else if (birthday.SelectSingleNode("FPXXMX/fpdm") != null)
                    fpdm = birthday.SelectSingleNode("FPXXMX/fpdm").InnerText;

                //读取数据 
                if (birthday.SelectSingleNode("fphm") != null)
                    fphm = birthday.SelectSingleNode("fphm").InnerText;
                else if (birthday.SelectSingleNode("FPXXMX/fphm") != null)
                    fphm = birthday.SelectSingleNode("FPXXMX/fphm").InnerText;

                //读取数据 
                if (birthday.SelectSingleNode("saveCode") != null)
                    saveCode = birthday.SelectSingleNode("saveCode").InnerText;
                else if (birthday.SelectSingleNode("FPXXMX/saveCode") != null)
                    saveCode = birthday.SelectSingleNode("FPXXMX/saveCode").InnerText;

                //读取数据 
                if (birthday.SelectSingleNode("saveMessage") != null)
                    saveMessage = birthday.SelectSingleNode("saveMessage").InnerText;
                else if (birthday.SelectSingleNode("FPXXMX/saveMessage") != null)
                    saveMessage = birthday.SelectSingleNode("FPXXMX/saveMessage").InnerText;



                if (birthday.SelectSingleNode("returnCode") != null)

                    returnMessage = birthday.SelectSingleNode("returnMessage").InnerText;

            }
