XML :: Looping And Pulling Options Into Multidimensional Array

Here is my xml structure:
<question>
<q1> Who coined the term "Clinical Psychology"�? </q1>
<answer> Lightner Witmer </answer>
<option1> Stanley Hall </option1>
<option2> Lightner Witmer </option2>
<option3> Henry P. David </option3>
</question>

I can loop through fine and pick out the questions and answers, then throw them into separate arrays. The problem I'm having is looping and pulling the options into a multidimensional array like such:
var one:Array = new Array( 3 );
one[0] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];
one[1] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];
one[2] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];
