XML : C# Functions to accept arguements from XML

This is an extension of a question I had beforehand

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");    

And this works completely fine. The issue I have is when I don't have a word in the XML file, but rather a property of a class. I have a singleton Player, and it has a autoproperty Name. To normally access it, I can just say:

  Console.WriteLine("Your name is:", Player.Instance.Name);    

But how do I, instead, keep this in the XML file? Like:

  <?xml version="1.0" encoding="utf-8" ?>  <root>    <world>      <region name="TestRegion">        <area name="TestArea">          <building name="Outside">            <room name="TutorialRoom">              <textToDisplay>"Your name is: {0}"</textToDisplay>              <extraString>Player.Instance.Name</extraString>            </room>          </building>        </area>      </region>    </world>  </root>    

When I use the past command, it simple thinks that whole section is a string, and outputs "Your name is: Player.Instance.Name"

Is there a way to solve this?
