Question

我遇到了无法正确读取的XML文件。我知道这是一个很好的档案；我只是在做一些愚蠢的事情。

以下是XML的示例：

我正在尝试使用以下代码（根据下面的建议进行更新）进行读取：

                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。让我感到困惑的是何时在阅读中使用“ d：”或“ a：”。规则是什么？

Answer 1

Army和Units不在命名空间中，但您要像在"http://schemas.datacontract.org/2004/07/ModelLib"命名空间（通过d前缀）中一样选择它们。

更改

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

到

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

然后继续将名称空间前缀切换为a：

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

这些也应与最初定义的d：

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

（或按照XML的使用将其全部切换到a。无论哪种方式，都要保持一致。）

以这种奇怪的格式加载此XML文件的正确方法是什么？
