100分请教查询读取XML数据!

Question

String FilePath = Server.MapPath("Diary.xml");
XmlDocument doc = new XmlDocument();
doc.Load(FilePath);
XmlNodeList nodes = doc.SelectNodes("/Diary/entry[./name='YourName']");
int Count = nodes.Count;
for(int i = 0; i < Count; i++)
{
   Response.Write(nodes.Item(i).InnerText + "<br>");
}以上将获得Name=YourName的所有Entry节点以及所有子节点及内容
1.如何加一个变量给Name节点供查询?
2.nodes.Item(i).InnerText得到的所有Entry节点以及所有子节点的内容,杂乱在一起,如何再按子节点(name,weather等)读取?

Answer 1

看sdk里的XmlDocument类，里面详细的例子。

遍历XML

        // Load the reader with the data file and ignore all white space nodes.         
        reader = new XmlTextReader(filename);
        reader.WhitespaceHandling = WhitespaceHandling.None;        // Parse the file and display each of the nodes.
        while (reader.Read()) {
           switch (reader.NodeType) {
             case XmlNodeType.Element:
               Console.Write("<{0}>", reader.Name);
               break;
