C# 生成xml文件

      //创建一个xml文件和主内容;            XmlDocument xmlDoc = new XmlDocument();            XmlElement xmlRoot = xmlDoc.CreateElement("root");      //主内容            xmlDoc.AppendChild(xmlRoot);      //选择节点                XmlNode nodeRoot = xmlDoc.SelectSingleNode("root");                //创建face方格1                XmlElement elemFace1 = xmlDoc.CreateElement("face1");                XmlElement elemFace1Img = xmlDoc.CreateElement("img");                elemFace1Img.InnerText = newFace1Img;                elemFace1.AppendChild(elemFace1Img);                XmlElement elemFace1Link = xmlDoc.CreateElement("link");                elemFace1Link.InnerText = newFace1Link;                elemFace1.AppendChild(elemFace1Link);                nodeRoot.AppendChild(elemFace1);                       //创建face方格2                XmlElement elemFace2 = xmlDoc.CreateElement("face2");                XmlElement elemFace2Img = xmlDoc.CreateElement("img");                elemFace2Img.InnerText = newFace2Img;                elemFace2.AppendChild(elemFace2Img);                XmlElement elemFace2Link = xmlDoc.CreateElement("link");                elemFace2Link.InnerText = newFace2Link;                elemFace2.AppendChild(elemFace2Link);                nodeRoot.AppendChild(elemFace2);                xmlDoc.Save(strXmlFilePath);
