Recently, in the final game of World Cup, French midfielder Zinedine Zidane

Recently, in the final game of World Cup, French midfielder Zinedine Zidane headbutted Italian defender Marco Materazzi for insulting him. In the aftermath, Zidane apologized in an interview with a French television but added that he didn't regret hic actions. Can one coherently apologize for an action yet not regret that action? Or is Zidane false in one of his claims (the apology or the lack of regret)?
