help system vehicle ;(

[Jacobob14]

I have this system and I need a function to change the owner of the vehicle

function getVehicleFromID ( ID ) 
 for id, i in ipairs (getElementsByType( "vehicle" )) do 
    if getElementID (i) == ID then 
      return i 
       end 
         end 
           end 
  
vehicles = {} 
function vehiclesCache () 
 vehicles = {} 
  for k, i in pairs (xmlNodeGetChildren( xmlLoadFile( "scripts/vehicles.xml" ) )) do 
    vehicles[xmlNodeGetAttribute ( i, "id" )] = { id = xmlNodeGetAttribute ( i, "id" ), model = xmlNodeGetAttribute ( i, "model" ), x = xmlNodeGetAttribute ( i, "x" ), y = xmlNodeGetAttribute ( i, "y" ),z = xmlNodeGetAttribute ( i, "z" ),rotX = xmlNodeGetAttribute ( i, "rotX" ),rotY = xmlNodeGetAttribute ( i, "rotY" ),rotZ = xmlNodeGetAttribute ( i, "rotZ" ),ptype = xmlNodeGetAttribute ( i, "ptype" ), owner = xmlNodeGetAttribute ( i, "owner" ), damage = xmlNodeGetAttribute ( i, "damage" ), r = xmlNodeGetAttribute ( i, "r" ), g = xmlNodeGetAttribute ( i, "g" ), b = xmlNodeGetAttribute ( i, "b" ), sr = xmlNodeGetAttribute ( i, "sr" ) or xmlNodeGetAttribute ( i, "r" ), sg = xmlNodeGetAttribute ( i, "sg" ) or xmlNodeGetAttribute ( i, "g" ), sb = xmlNodeGetAttribute ( i, "sb" ) or xmlNodeGetAttribute ( i, "b" ) }

  return vehicles 
end
