Load the line resource for the textblock x: Uid in the code behind

I have a string resource that I am using to set as x: uid for a text block

<data name="Expected.Text" xml:space="preserve">
    <value>Expected Text</value>
</data>

<TextBlock x:Name="control" x:uid="Expected />

      

        
        
        
      

    

I am trying to write a Unit test to check if the text is correct. However, I cannot get the handle to the string "Expected" because at the end it has a .text to show up in the TextBlock

ResourceLoader loader = ResourceLoader.GetForCurrentView();
var expected = loader.GetString("Expected");
Assert.AreEqual(expected, control.Text);

      

        
        
        
      

    

This code fails because var is expected to be empty
