Actionscript object referencing from a string AS 3.0

Hey, I've got a question about refrencing properties from an actionscript object.

If i've got the following object named "groups"...

group1
   item1 = sampledata1 
   item2 = sampledata2
   item3 = sampledata3
group2
   item1 = sampledata4
   item2 = sampledata5
   item3 = sampledata6

I would access group1/item2 by typing "groups.group1.item2"

How would I create a method, where I can pass in the key in string form, and retrieve the data at that node. For example

groups.group1.item2 would return sampledata2

and

getItem("group1.item2"); would also return sampledata2

I think this is possible using eval(), but I believe that was removed in AS 3.0 which i'm using. Is there any other way to do this? Thanks.

Use Objects the way you would use hashes.

You can initialize objects this way: 

groups = 
{
   "group1":
   {
       "item1":sampledata1,
       "item2":sampledata2
   },
   "group2":
   {"item1":sampledata1...
   }
};

Or using brackets:

groups = new Object();
groups["group1"] = new Object();
groups["group1"]["item1"] = sampledata1;

Access is done like this:

groups["group1"]["item1"]

hope that helps.
