Algorithm

i am trying to store some shopping cart details in a cookie. I have been able to do that but i want to now retrieve the values and put them in a shopping cart table. An example of the cookie file is

Product1=value,Quantity1=value,Price1=value,Extras1=value;
Product2=value,Quantity2=value,Price2=value,Extras2=value;

I have been able to retrieve the 2 cookies

cookieArray = document.cookie.split("; ")
for(i=0; i<cookieArray.length ; i++)
{
document.write(cookieArray[i] +"<br>")
}

But now for each Product i want to retrieve the 4 values. Can anyoine help me with this or suggest a better way to achieve the same thing.
