parsing xml into 3d array AS2

[havey]

Hi i would like to know how to parse the following xml into a 3d array.
The number of rLables is unsure. I would like the array to be
3Darr[na][cm][mo]

here is the xml and below is my attempt:

<rEnd>
        <Lables>
            <rLables names="name this" cMod="10" modname="a1"></rLables>
        </Lables>
        <Lables>
            <rLables names="name that" cMod="15" modname="aa1"></rLables>
        </Lables>
        <Lables>
            <rLables names="name A" cMod="10" modname="zz"></rLables>
        </Lables>
        <Lables>
            <rLables names="name 4" cMod="5" modname="mo7"></rLables>
        </Lables>
</rEnd>

Thanks.

3Darr:Array [];
na:String, cm:Number, mo:String

var rEnd= this.firstChild.childNodes; 

for (var r=0; r<rEnd.length; r++){ 
  
var Lables = rEnd[r]; 

  for (var s=0; s<rLables.length; s++){ 
   3Darr[na]=rLables.attributes.names;
   3Darr[cm]=rLables.attributes.cMod;
   3Darr[mo]=rLables.attributes.modname;
  } 
}

_xml = new XML();
_xml.ignoreWhite = true;
_xml.load("test.xml");

_xml.onLoad = function(){
aNode = this.firstChild.childNodes; 
len = aNode.length;
oArr = [];

for (var r=0; r<len; r++){ 
obj = {};
obj.na = aNode[r].firstChild.attributes['names'];
obj.cm = aNode[r].firstChild.attributes['cMod'];
obj.mo = aNode[r].firstChild.attributes['modname'];
oArr[r] = obj;
} 
};

/*-- code produces this array --
oArr =  [
    0:[object #8, class 'Object'] {
      na:"name this",
      cm:"10",
      mo:"a1"
    },
    1:[object #9, class 'Object'] {
      na:"name that",
      cm:"15",
      mo:"aa1"
    },
    2:[object #10, class 'Object'] {
      na:"name A",
      cm:"10",
      mo:"zz"
    },
    3:[object #11, class 'Object'] {
      na:"name 4",
      cm:"5",
      mo:"mo7"
    }
  ]
