How make animation on Unity 3D from XML file?

I have a GO that inside it has three Cubes (GO) where an arrow out of a cube to another.

The position information and animation comes from the XML file. Read XML file that's OK. The difficult for me it is to animate with XML informations. I don't find a tutorial easy explaining how animation on script.

Anyone can help me?

Below an example:

 <group name="one" start="x,y,z" end="x,y,z">
 <gameobjects>
     <gameobject name="Cube1" start="x,y,z" end="x,y,z">
     <gameobject name="Cube2" start="x,y,z" end="x,y,z">
     <gameobject name="Cube3" start="x,y,z" end="x,y,z">
 </gameobjects>
     <arrows>
         <arrow name="arrow1" start="x,y,z" end="x,y,z">
         <arrow name="arrow1" start="x,y,z" end="x,y,z">
     </arrows>
 </group>
 
 <group name="two" start="x,y,z" end="x,y,z">
     <gameobjects>
         ...
     </gameobjects>
     <arrows>
         ...
     </arrows>
 </group>
 
 <group name="three" start="x,y,z" end="x,y,z">
     ...
 </group>
