C#中用XMLDocument写文件时，去掉XMLNS属性

核心：在CreateElement时设置  newDoc.CreateElement("orderinfo", newDoc.DocumentElement.NamespaceURI);

 

private Boolean CreateNewEcg(string oldEcgXML, string newEcgXML)
        {
            try

                XmlNamespaceManager ns = new XmlNamespaceManager(doc.NameTable);
                ns.AddNamespace("", "http://www3.medical.philips.com");
                ns.AddNamespace("default", "http://www3.medical.philips.com");

                XmlNode xnDocumentinfo = doc.SelectSingleNode("descendant::default:documentinfo", ns);
                XmlNode xnPatient = doc.SelectSingleNode("descendant::default:patient", ns);
                XmlNode xnOrder = doc.SelectSingleNode("descendant::default:orderinfo", ns);
                XmlNode interpretations = doc.SelectSingleNode("descendant::default:interpretation", ns);
                List<string> statementList = new List<string>();
                //interpretation
                if (interpretations != null)
                {
                    foreach (XmlNode xnState in interpretations.SelectNodes("descendant::default:statement", ns))
                    {
                        statementList.Add(xnState.InnerText);
                    }
                } 

                XmlDocument newDoc = new XmlDocument();
                XmlDeclaration dec = newDoc.CreateXmlDeclaration("1.0", "utf-16", null);

                {
                    XmlNode nodeStates = newDoc.CreateElement("statements", newDoc.DocumentElement.NamespaceURI);//newDoc.CreateElement("","statements","");
