请问递归函数的工作？

 静态无效的主要（）{
 XmlDocument的DOC =新的XmlDocument（）; 
 doc.Load（的test.xml）; 

 ReadNode（doc.GetElementsByTagName（对象）[0]）; 
到Console.ReadLine（）; 
} 

静态无效ReadNode（XmlNode的节点）{
 //完成与每个节点
的东西，如果（node.Attributes.Count大于0）{
的foreach（在node.Attributes XmlAttribute ATTR）{
 //使用每个属性
}东西如果
} 
（node.HasChildNodes ==真）{
的foreach（在node.ChildNodes XmlNode的chlnode）{
 ReadNode（chlnode）; 
} 
} 
} 
 

您可以使用 XmlNode.Name 来知道你处理的节点。

How i can parse multiple nodes & child nodes in one XML file? Here the file structure:

<objects>

 <object id=1 name="test" param="1">
   <attribute key = "test" value="1"/>

   <subobjects>
    <subobject id=2 value="test" param="some"/>
    <subobject2 id=2 value="test" param="some"/>
    <subobject3 id=2 value="test" param="some"/>
   </subobjects>

 </object>

 <object id=2 name="newtest" param="44">
   <attribute key = "test1" value="1"/>
   <attribute key = "test2" value="2"/>
   <attribute key = "test3" value="3"/>

   <subobjects>
    <subobject id=1 value="intvaluetest" param="1"/>
   </subobjects>

 </object>

</objects>

I am try to make a reader-parser for this, and him sucessufy reads object and attribute keys, but i dont have idea, how i can read node and their children nodes in this format (as on xml example) My reader is:

    XmlDocument document = new XmlDocument();
    document.Load(fileName);

    foreach (XmlNode node in document.GetElementsByTagName("object"))
    {
        ushort id = ushort.Parse(node.Attributes["id"].InnerText);
        //do some things

        foreach (XmlAttribute attr in node.Attributes)
        {
            switch (attr.Name.ToLower())
            {
                case "name":
                    //do things
                    break;
                case "param":
                    //do things
                    break;
            }
        }

        if (node.HasChildNodes)
        {
            foreach (XmlNode attrNode in node.ChildNodes)
            {
                if (attrNode.Attributes != null &&
                    attrNode.Attributes.Count > 0 &&
                    attrNode.Attributes["key"] != null &&
                    attrNode.Attributes["value"] != null)
                {
                    string value = attrNode.Attributes["value"].InnerText;
                    switch (attrNode.Attributes["key"].InnerText.ToLower())
                    {
                        case "test":
                            //do things with value
                            break;
                    }
                }
            }
        }

Please, any solution in C# for XML parse nodes and child nodes in this case? I think nodeList=root.SelectNodes() - non better idea in this cause. <subobjects> - is children node of object, and this have a their non-static (for each object - different) type of sub-object. Any idea?

Would a recursive function work?

static void Main() {
    XmlDocument doc = new XmlDocument();
    doc.Load("test.xml");

    ReadNode(doc.GetElementsByTagName("object")[0]);
    Console.ReadLine();
}

static void ReadNode(XmlNode node) {
        //Do something with each Node
        if(node.Attributes.Count > 0) {
            foreach(XmlAttribute attr in node.Attributes) {
                //Do Something with each Attribute
            }
        }
        if(node.HasChildNodes == true) {
            foreach(XmlNode chlnode in node.ChildNodes) {
                ReadNode(chlnode);
            }
        }
    }

You could use XmlNode.Name to know which node you're dealing with.
