c# - Query Collection of all XML Elements

Question

I'm looking to parse an XML file, and have the ability to search any element.

My XML code looks rather nontraditional (out of my control):

<DiagReport>
<LicensingData>
  <ToolVersion>6.3.9431.0</ToolVersion>
  <LicensingStatus>SL_LICENSING</LicensingStatus>
</LicensingData>
<Health>
  <Result>PASS</Result>
  <TamperedItems></TamperedItems>
</Health>
<Genuine>
  <ServerProps>GenuineId</ServerProps>
</Genuine>
</DiagReport>

I'd like to load each singular element into a collection, i.e. one collection including ToolVersion, Result, etc. From there, I'd like to iterate through each element/name pair, and depending upon the element, do something different:

if (element.Equals(Result))
    //do something with "PASS"

Is this possible to do with LINQ?

Answer 1

您可以使用 LINQ to XML 遍历所有二级元素：

  var xdoc = XDocument.Load(@"C:\test.xml");
    foreach (var element in xdoc.Element("DiagReport").Elements().Elements())
    {
        if (element.Name == "Result")
        {
            string value = element.Value;
        }
    }

Answer 2

您可以使用Linq to Xml查询您的Xml文档，您可以搜索Elements，Attributes并获取您需要的内容。

您可以创建如下所示的简单查询。

  XElement root = XElement.Parse(File.ReadAllText("C:\\Test.xml"));
  var test = new 
  {
      ToolVersion = root.Descendants("ToolVersion").FirstOrDefault().Value,
      Result = root.Descendants("Result").FirstOrDefault().Value
  };
