ActionScript 2.0 :: Extracting Arrays From Textfile?

I have a variable which takes a particular form of array (used with the component DataSet). It looks like this:

Code:
var recData = [{svenska:"Hej", spanska:"Hola"}, {svenska:"nej", spanska:"no"}, {svenska:"ocks�", spanska:"tambi�n"}];

I want to extract this variable from a textfile instead of writing it directly into the code-area of the flash-file, so I used the following code:

Code:
// 1) Loads the textfile, recieves the array, and puts it into a variable called txt_Data
var txt_DataSet = new LoadVars();

[Code]....

Unfortunately it seems the array gets converted to an ordinary string in the process, so I cant use it properly. Is there a way I could extract the array from this string again, and if so, how?
