Make C# function stored in XML

I have a specific function that I want to run, and it is located inside an XML File:

Console.WriteLine("Text for test, {0}, {1}", testWord, testWord2);

The text is stored in an XML file:

<?xml version="1.0" encoding="utf-8" ?>
<root>
  <world>
    <region name="TestRegion">
      <area name="TestArea">
        <building name="Outside">
          <room name="TutorialRoom">
            <textToDisplay>"Text for test, {0},{1}"</textToDisplay>
            <extraString>testWord,tesWord2</extraString>
          </room>
        </building>
      </area>
    </region>
  </world>
</root>

I can easily get the string data using LINQ

XElement xelement = XElement.Load("..\\..\\LocationDatabase.xml");

        var textToDisplay= xelement.Elements("world")
            .Elements("region").Where(region => (string)region.Attribute("name") == "TestRegion")
            .Elements("area").Where(area => (string)area.Attribute("name") == "TestArea")
            .Elements("building").Where(building => (string)building.Attribute("name") == "Outside")
            .Elements("room").Where(room => (string)room.Attribute("name") == "TutorialRoom")
            .Elements("textToDisplay");

        var extraString= xelement.Elements("world")
            .Elements("region").Where(region => (string)region.Attribute("name") == "TestRegion")
            .Elements("area").Where(area => (string)area.Attribute("name") == "TestArea")
            .Elements("building").Where(building => (string)building.Attribute("name") == "Outside")
            .Elements("room").Where(room => (string)room.Attribute("name") == "TutorialRoom")
            .Elements("extraString");

My issue here is how I make the command `Console.WriteLine("Something {0}", extra); to accept both LINQ statements. Anybody have an idea?
