如何使用C#和LINQ提取XML深处的信息
我已经阅读过类似的主题，并且很难根据我自己的问题调整其中显示的方法。这可能是因为我对LINQ和C#的理解很弱，因为在这个特定项目中，我必须学习这两个方面。我们正试图从第三方路由管理软件包发送给我们的xml中提取路由交付数据。 由于xml表是以一种奇怪的方式构造的（或者在我看来是这样），我一直在努力找出一种合理的结构来提取里程表、时间和帐户ID等值，因为它们分散在每个路由的“实际”元素和“计划”元素中 下面是一个xml示例，其中每个RoutedDetailResponseeDeveloperOutletail都是一个路由：如何使用C#和LINQ提取XML深处的信息,c#,xml,linq,C#,Xml,Linq,我已经阅读过类似的主题，并且很难根据我自己的问题调整其中显示的方法。这可能是因为我对LINQ和C#的理解很弱，因为在这个特定项目中，我必须学习这两个方面。我们正试图从第三方路由管理软件包发送给我们的xml中提取路由交付数据。 由于xml表是以一种奇怪的方式构造的（或者在我看来是这样），我一直在努力找出一种合理的结构来提取里程表、时间和帐户ID等值，因为它们分散在每个路由的“实际”元素和“计划”元素中 下面是一个xml示例，其中每个RoutedDetailResponseeDeveloperOut

我确信有一种更有效的方式来解决这个问题，但我对这件事感到茫然。非常感谢您提供的任何帮助。目前的问题是，您的任务是处理XML文件中的实际信息数据库 不是数据分析的最佳方案 以更有效的方式解决问题 我建议您创建一个具有合理结构的关系数据库（可能是sql express）。一旦数据库被设置好，就有一个简单地使用数据（做你现在正在做的事情）来填充数据库的进程
你可以在C语言或SQL中进行基本的查询来提取手头所需要的数据。
如果你处理的是定义良好的模式，不能迁移，你可以考虑通过删除大量不必要的代码来帮助我。不过要仔细观察你的表现。
我认为你是对的。如果我只是填充两个表，而不是一次全部填充，那么我应该能够将计划表和实际表分开，并使用routeID作为键来运行SQL查询，以便以可用的格式将数据组合在一起。谢谢你的建议。XmlDocument dom = new XmlDocument();
dom.LoadXml(ToXml(response2).ToString());
dom.PreserveWhitespace = true;
dom.Save("C:\\DRTrack XML Import Archive\\" + DateTime.Today.AddDays(-1).Date.ToString("MM-dd-yyyy") + ".xml");
