You could do the same using an associative array (Object/Hashtable). Iterate through the data one time, using bracket notation to create the properties. You can't iterate in order over this structure, if that matters.

Use a dictionary to store you're unique values. So iterate through your data and use the data as the key for the dictionary Var myDictionary : Dictionary = new Dictionary(); myDictionary[value] = value; //value would be whatever you are wishing to store, should you iterate through a dataset and have more than one value which is the same then it will end up only being stored once. //then you could pass it all into an ArrayCollection so that you could bind to that data or similar. public function getUniqueValues (val : Dictionary) : ArrayCollection { var unique = new ArrayCollection(); for(var prop :String in val){ unique.addItem(val[prop]); } } Hope that's what your after. If you have a very large dataset then you don't need to do any checking if it already exists in the dictionary, so I'm presuming it will be reasonably efficient. Kenneth.

Is there a quick and dirty way to do this? I could push to an array if the value doesn't already exist, however I did not know if there was a more efficient way to get these values. Example: <data> <projects name="Project A" /> <projects name="Project B" /> <projects name="Project C" /> <projects name="Project A" /> </data> Unique values would be: Project A, Project B, Project C Thanks for any and all replies.
