Need a help regarding "splitting"


i am having a small doubt in flash. i am loading an external .txt file and am displaying. its working fine. but when am trying to split the specified values, the value was disappearing. i mean except that splitted value everything is displaying… how to get that.

var loadXML:XML = new XML();
var myarr:String;
loadXML.ignoreWhite = true;
loadXML.onLoad = function(success) {
myarr = loadXML.toString()

" pictures.txt " contains

<picture thumb=“test-images/01.png” description=“Tons of customisation options” name=“” param="_blank"></picture>
<picture thumb=“test-images/02.png” description=“User controlled rotation or auto-rotate” name=“” param="_blank"></picture>
<picture thumb=“test-images/03.png” description=“Item description” name=“” param="_blank"></picture>

its an xml string based.

now i want to store the picture thumb value in one array value, and description value in another… like tat…

any solutions would be appreciated…
