Question

我尝试读取一些XML，然后将特定信息写入控制台，我的XML文件位于https://aaronlilly.github.io/demo/demo.xml

或也在此处列出：

<DogCenter xmlns="http://schema.dogsite.com/xsi">
  <dogActiveState>Available</dogActiveState>
  <useDefaultGuardDog>false</useDefaultGuardDog>
  <enableGuardDog>true</enableGuardDog>
  <guardTimerSeconds>7</guardTimerSeconds>
  <useDogOther>true</useDogOther>
  <forceHumanToPlay>true</forceHumanToPlay>
  <forceDogInCrate>false</forceDogInCrate>
  <forceDogFoodLimit>true</forceDogFoodLimit>
  <numberConsecutiveBallsBounce>4</numberConsecutiveBallsBounce>
  <makeBarkingNoiseIfMailMan>true</makeBarkingNoiseIfMailMan>

      <dogLevel>5</dogLevel>
    </centerDetails>
    <centerDetails>
      <TrainerId>Aaron</TrainerId>

    <centerDetails>

      <isLogOffAllowed>false</isLogOffAllowed>
      <dogLevel>12</dogLevel>
    </centerDetails>
  </dogCenterList>
</DogCenter>

我想写的是示例

TrainerID = Bingo , Available = True, dogLevel = 12;

对于每个TrainerId（例如，宾果游戏，顶点游戏，蒙娜丽莎）

到目前为止，我所得到的是这个

XmlElement elem = (XmlElement)doc.DocumentElement.FirstChild;
Console.Write("{0} = {1}", elem.Name, elem.InnerText);

哪个写dogActiveState = Available ;

我尝试了for循环

for (int x = 0; x < elem.ChildNodes.Count; x++)
{
    Console.WriteLine("{0} = {1}"",elem.Name, elem.InnerXml);
}

和

for (int x = 0; x < elem.ChildNodes.Count; x++)
{
    Console.WriteLine("{x}={x+1}",elem.Name, elem.InnerXml);
}

但是我还没有完全掌握语法。

您可以使用XmlDocument.GetElementsByTagName获取callCenterDetails元素，并使用XmlNode indexer访问其子元素。这是一个示例：

var doc = new XmlDocument();
doc.Load("demo.xml");
var callCenterDetails = doc.GetElementsByTagName("callCenterDetails");
for (var i = 0; i < callCenterDetails.Count; i++)
{
    var trainerId = callCenterDetails[i]["TrainerId"].InnerText;
    // ...
}

访问XML中的属性/节点
