Question

我有一个XML，我将其加载到我的C＃程序中。我想要实现的目标是计算军队的数量＆＃34;每个＆＃34;联盟内的元素＆＃34;元件。

以下是每个＆＃34;联盟＆＃34;包含三个＆＃34;军队＆＃34;元素。因此，我想要实现的结果是有两个变量，结果为3。

你能帮忙吗？非常感谢

您可以Linq使用Xml并查询后代和元素，如下所示。

    XDocument doc = XDocument.Load(filename);


    var results = doc.Descendants("alliance")                                
                     .Select(g=> 
                             new 
                             {
                                 ID = g.Attribute("id").Value, 
                                 ArmyCount =   g.Elements("army").Count() 
                             });

可以使用 XmlDocument 和 SelectNodes 完成替代方法：

List<int> listCount = new List<int>();
XmlDocument docXMLs = new XmlDocument();
docXML.Load("path to file.xml");

XmlNodeList listAlliance = docXML.SelectNodes("Battle/Alliance");
foreach(XmlNode nodeAlliance in listAlliance )
{
    XmlNodeList listArmy = nodAlliance.SelectNodes("Army");
    listCount.Add(listArmy.Count);
}

请注意，我没有尝试过上述代码，可能有更有效的方法。如果答案可以改进，那么我感谢任何建设性的评论！
