c# xml linq 正确的方法？

Question

我阅读了有关 Linq 和 xml 的信息，但我不知道我是否以正确的方式...

这里是我的 XML 配置文件：

<?xml version="1.0" encoding="utf-8"?>
<Configuration>
  <Priorities>
    <Priority Index="0">Zero</Priority>
    <Priority Index="1">One</Priority>
    <Priority Index="2">Two</Priority>
    <Settings>
      <Name>PriorityName</Name>
      <DisplayName>PriorityDisplayName</DisplayName>
      <Active>true</Active>
      <Index>0</Index>
    </Settings>
  </Priorities>
  <Workcenters>
    <Workcenter Index="0">TEAM_0</Workcenter>
    <Workcenter Index="1">TEAM_1</Workcenter>
    <Workcenter Index="2">TEAM_2</Workcenter>
    <Settings>
    <Name>WorkcentersName</Name>
    <DisplayName>WorkcentersDisplayName</DisplayName>
    <Active>false</Active>
    <Index>1</Index>
    </Settings>
  </Workcenters>
  <ErrorPages>
    <ErrorPage>
      <Name>Error_1</Name>
      <Type>Critical</Type>
    </ErrorPage>
    <ErrorPage>
      <Name>Error_2</Name>
      <Type>Normal</Type>
    </ErrorPage>
 </ErrorPages>
</Configuration>

现在我像这样访问所有优先级：

 //Get Prios
            XElement xelement = XElement.Load(xmlPath2);
            IEnumerable<XElement> priorities = xelement.Descendants("Priorities");
            var prios = priorities.Elements("Priority").ToList();
            var settings = priorities.Elements("Settings");
            foreach (XElement priority in prios)
            {
                Console.WriteLine(priority.Attribute("Index").Value);
                Console.WriteLine(priority.Value);
            }

            foreach (XElement setting in settings)
            {
                Console.WriteLine(setting.Element("Name").Value);
                Console.WriteLine(setting.Element("Active").Value);
                Console.WriteLine(setting.Element("Index").Value);
                Console.WriteLine(setting.Element("DisplayName").Value);
            }

这是访问元素的正确方法吗？ 我认为会有更好的阅读解决方案。

你能帮帮我吗？

谢谢

您可以使用XPathSelectElements 扩展方法。

所以你的代码看起来像：

        XElement xelement = XElement.Load(xmlPath2);         

        foreach (XElement priority in xelement.XPathSelectElements("Priorities/Priority"))
        {
            Console.WriteLine(priority.Attribute("Index").Value);
            Console.WriteLine(priority.Value);
        }

        foreach (XElement setting in xelement.XPathSelectElements("Priorities/Settings"))
        {
            Console.WriteLine(setting.Element("Name").Value);
            Console.WriteLine(setting.Element("Active").Value);
            Console.WriteLine(setting.Element("Index").Value);
            Console.WriteLine(setting.Element("DisplayName").Value);
        }
