[flexcoders] [HELP] Little help with parsing datas

[~[TM3]~[Dev]At0ng[/Dev]~[/TM3]~]

I recently have this code from gotoandlearnforums to parse datas
separated with commas from a text file but the problem is I dunno (I
really had no idea how) how to exclude rows that begins with a double
slashes (//), hope someone can help me with this. Parsing datas is ok
but excluding rows is not           private function init(e:Event):void
{             //load the data             var loader:URLLoader = new
URLLoader(new URLRequest("stuff.txt"));            
loader.addEventListener(Event.COMPLETE, parseData);          }         
private function parseData(e:Event):void          {
var txt:String = e.target.data;             var rows:Array =
txt.split("\r\n");//split the string into rows                         
var temp:Array = new Array();                          for(var i:int =
0; i<rows.length; i++)             {                //you would include
an if statement here to not include lines that begin with //
var columns:Array = rows[i].split(",");//split each row into columns
temp.push({id:columns[0],name:columns[1],position:columns[2]});
}             ac = new ArrayCollection(temp)
