Query Collection of all XML Elements

问题

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?

回答1:

You can use LINQ to XML to iterate through all second level elements:

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

You can use Linq to Xml to query your Xml document, you can search Elements, Attributes and grab what you need.

More information can be found here: Basic Queries (LINQ to XML)

And you can creat simple querys like below.

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