Motion Tracking Data into Animation Nodes Editor?

I've created a simple motion track from video in the movie clip editor. I can see the motion data in the graph view:

I've also created an empty from the motion data and when I hit playback I can see the empty moving in the 3D view.

The problem is that when I add the empty as an object to the Node Animation area and wire it to any other node, I never see the X/Y values change over time during playback. Here's my current node layout:

(EDIT: I'm using the text node to view the value of the X coordinate in real time during the animation playback).

I know that the motion data can be used in the Compositor layout using the Track Position Node, but I want to use the tracking data to animate an object in the 3d space and am assuming the Animation Node editor would be more appropriate.

Is there any way of getting the empty's location data into the Animation Node editor or barring that, passing the Track Position output from the Compositor Node editor into the Animation Node editor?

UPTDATE: As recommended by SergeL, here's is how to retrieve the tracker empty location data using Animation Nodes:

• Try to use Matrix input + Matrix Decompose instead of Transforms Input – Serge L Jan 12 '19 at 15:32
• Use the Word matrix to retrieve the location. – Jaroslav Jerryno Novotny Jan 12 '19 at 15:33
• An easier way to investigate the value of a certain data is to user a viewer node, see documentation. – Omar Emara Jan 12 '19 at 15:35
• @SergeL - That worked! I've updated my question with the details. – user1354111 Jan 13 '19 at 8:58
