初识Xml，一点菜鸟心得

创建Xml文件，必须添加根元素，否则报错

代码

XmlElement Ele;
            XmlDocument XDoc = new XmlDocument();
            XDoc.Load(FileName );
            XmlElement Root = XDoc.DocumentElement;
            XmlElement XEle = XDoc.CreateElement("Node");
            XEle.SetAttribute("name",ConsumerName );
            for (int i = 0; i < Count; i++)
            {
                Ele = XDoc.CreateElement("Place");
                Ele.InnerText = ConsumerPlace[i].ToString();
                XEle.AppendChild(Ele );
            }
            Root.AppendChild(XEle );
            XDoc.Save(FileName );

 

其中ConsumerPlace为Arraylist，AppendChid（）是将指定节点添加到该节点的子节点列表的末尾

//读取
string Str = "/ConsumerInformation/Node[@name='"+ConsumerName +"']";
            ConsumerPlace.Clear();  //清空列表
            XmlDocument XDoc = new XmlDocument();
            XDoc.Load(FileName );
            XmlElement Root = XDoc.DocumentElement;
            XmlElement  XEle =(XmlElement ) Root.SelectSingleNode(Str );  //遍历寻找name节点
            XmlNodeList Node = XEle.ChildNodes;   //将name节点的子节点赋给Node
            int Count = Node.Count;
            for (int i = 0; i < Count; i++)
            {
                ConsumerPlace.Add(Node [i].InnerText );
            }

 

Xml文件内容

<?xml version="1.0" encoding="utf-8"?><ConsumerInformation>  <Node name="houqidian">    <Place>黄山</Place>    <Place>安徽</Place>  </Node>  <Node name="yifeng">    <Place>张家界</Place>    <Place>庐山</Place>  </Node>  <Node name="扬子">    <Node>北京</Node>    <Node>长沙</Node>    <Node>海南</Node>    <Node>佛山</Node>  </Node></ConsumerInformation>
