Select string from within brackets - regex maybe ?

I have a string which looks something like this
{Rare,Medium,Gennemstegt}{Pommes,Bagt Kartoffel{Hvidløg,Krydder,Smør}}{Sovs1,Sovs2,Sovs3}

it can ofcause change alot - depending on user input

does anyone know a split command or alike which could give me the following result
arr(0) = {Rare,Medium,Gennemstegt}
arr(1) = {Pommes,Bagt Kartoffel{Hvidløg,Krydder,Smør}}
arr(2) = {Sovs1,Sovs2,Sovs3}

I was thinking of simply looping through the string and counting the number of { and  } once these were equal i would have my first string, then proceed however could this be done by a Regular Expression or ?Start Free Trial
