XML

so im tring to to loop trough some nodes in xml.

my xml file looks like this :

<?xml version="1.0" encoding="utf-8" ?>
<RoundType>
  
  <name>
   StartRound
  </name>
  
  <ActionGroups>
    
    <group>
      <name>
        STANDART
      </name>
      <path>
        STANDART
      </path>
    </group>
    
  </ActionGroups>
  
</RoundType>

i have tried this:

using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace SurvivalGamesLib
{
    class ActionHandler
    {
        public List<XmlDocument> LoadActions(XDocument roundType) 
        {
            List<XmlDocument> actions = new List<XmlDocument>();

            List<string> groups = new List<string>();

            

            foreach (var node in roundType.Element("RoundType").Element("ActionGroups").Elements("group"))
            {
                Console.WriteLine("test");
                Console.WriteLine(node.Element("name").Value);
            }


            return actions;
        }

    }
}

but when i run it i always get this error:

System.NullReferenceException: 'Object reference not set to an instance of an object.'

System.Xml.Linq.XContainer.Element(...) returned null.


is there someone that knows a solution for this ?

What I have tried:

searching google. but al the solutions i found did not work in my case.
