Performant way to get single element from XML - C#

Question

I got XML code like this:

<Body>
  <Schoolyear>2016</Schoolyear>
  <ClassLeader>
    <Id>200555</Id>
    <Name>Martin</Name>
    <Short>ma</Short>
  </ClassLeader>
  <Info>
     some very useful information :)
  </Info>
</Body>

I only need one tag, eg SchoolYear

I tried this:

foreach (XElement element in Document.Descendants("Schoolyear"))
{
   myDestinationVariable = element.Value;
}

It works, but I think maybe there is a more performant and easier solution.

Answer 1

You can take it using LINQ or just use Element with the specified XName

Add namespace

using System.Xml.Linq;

And use one of these examples

        string xml = @"<Body>
  <Schoolyear>2016</Schoolyear>
  <ClassLeader>
    <Id>200555</Id>
    <Name>Martin</Name>
    <Short>ma</Short>
  </ClassLeader>
  <Info>
     some very useful information :)
  </Info>
</Body>";

 XDocument dox = XDocument.Parse(xml);

 var exampl1 = dox.Element("Body").Element("Schoolyear").Value;

 var exampl2 = dox.Descendants().FirstOrDefault(d => d.Name == "Schoolyear").Value;
