C#怎样将节点<ULAC>改成<moi xsi:type="ULAC">，<USAC>改成<moi xsi:type="USAC">

[zhanshang2606]

还有 </USAC>和</USAC>改成</moi>

修改下 是

private static void UpdateXml(string path)
        {
            if (File.Exists(path))
            {
                XmlDocument doc = new XmlDocument();
                doc.Load(path);
                XmlNode ulac = doc.DocumentElement.SelectSingleNode("//ULAC");
                if (ulac != null)
                {
                    XmlNode newNode = doc.CreateElement("moi");
                    XmlAttribute attr = doc.CreateAttribute("xsi", "type", "");
                    attr.Value = "ULAC";
                    newNode.Attributes.Append(attr);
                    newNode.InnerXml = ulac.InnerXml;
                    ulac.ParentNode.ReplaceChild(newNode, ulac);
                }
                XmlNode usac = doc.DocumentElement.SelectSingleNode("//USAC");
                if (usac != null)
                {
                    XmlNode newNode = doc.CreateElement("moi");
                    XmlAttribute attr = doc.CreateAttribute("xsi", "type", "");
                    attr.Value = "USAC";
                    newNode.Attributes.Append(attr);
                    newNode.InnerXml = usac.InnerXml;
                    usac.ParentNode.ReplaceChild(newNode, usac);
                }
                doc.Save(path);
            }
        }
