Good Day Kglad:
Excuse, I do what you said, I copy and paste but it gave an error:
1084: Syntax error: expecting rightbracket before ampersand. Line 93
THIS IS THE LINE:
var dp:DataProvider = new DataProvider([xml@name,xml@address]);   
// textInput  changeHandler function
function changeHandler(event:Event):void {
var xml:XMLList = XMLList(loader.data.name.(@name.indexOf(itemTextInput.text)>-1));
var dp:DataProvider = new DataProvider([xml@name,xml@address]); 
// you may want to switch rows and columns which would look like:
var a:Array = [];
for(var i:int=0;i<xmlList.length();i++){
  a[i] = [xmlList[i].@name,xmlList[i].@address]
var dp:DataProvider=new DataProvider(a);
dg.dataProvider = dp;
Thank you in advance Kglad
