以这种奇怪的格式加载这个XML文件的正确方法是什么？

问题描述 投票：-5回答：1

我遇到了一个我无法正确阅读的XML文件。我知道这是一个好文件;我只是在做一些愚蠢的事情。

以下是XML的示例：

    - <Army xmlns:i="http://www.w3.org/2001/XMLSchema-instance">

我正在尝试使用此代码阅读它（根据以下建议更新）：

                XmlDocument xmlDoc = new XmlDocument();
                xmlDoc.Load(ScenarioFilename);
                XmlNamespaceManager nsm = new XmlNamespaceManager(xmlDoc.NameTable);

                nsm.AddNamespace("d", "http://schemas.datacontract.org/2004/07/ModelLib");
                var nodeList = xmlDoc.SelectNodes("/Army/Units/d:Unit", nsm);
                bool tempval;

                foreach (XmlNode node in nodeList)
                {
                    tempHQ = node.SelectSingleNode("d:HQ", nsm).InnerText;
                    tempID = node.SelectSingleNode("d:ID", nsm).InnerText;
                    Boolean.TryParse(tempHQ, out tempval);
                    RedArmy[Int32.Parse(tempID)].IsHQ = tempval;
                }// foreach

但是，nodelist返回0项。令我困惑的事情之一是何时在阅读中使用'd：'或'a：'。规则是什么？

c# xml xml-namespaces

Army和Units没有命名空间，但你选择它们就像它在"http://schemas.datacontract.org/2004/07/ModelLib"命名空间（通过d前缀）。

更改

var nodeList = xmlDoc.SelectNodes("/d:Army/d:Units/d:Unit", nsm);

至

var nodeList = xmlDoc.SelectNodes("/Army/Units/d:Unit", nsm);

然后，您继续将名称空间前缀切换到a：

  tempHQ = node.SelectSingleNode("a:HQ", nsm).InnerText;
  tempID = node.SelectSingleNode("a:ID", nsm).InnerText;

那些也应该像最初定义的那样，d：

nsm.AddNamespace("d", "http://schemas.datacontract.org/2004/07/ModelLib");

（或者像XML一样切换到a。无论哪种方式，都要保持一致。）
