Reincarnation and XP gain?

Do you gain XP from killing a unit if he still has Reincarnation and will reincarnate? How does this work, do you gain XP all times, even if he dies and reincarnates like 5 times?

If the unit has the ability called reincartion it doesn't give experience

but I thiink that when a hero dies using the item ankh of reincarnation, he gives experience
