AS3: Dynamic XMLListCollection

Question

Hi,
I am writing AIR app emulating Excel 2007.
Trying to initialize a DataGrid dataProvider, which is XMLListCollection.
Need to create something like that:
<root>
<row><A/><B/><C/>...</row>
</root>
But the number of rows and columns should be paramatrized like:
private function initDG(colNum:int, rowNum:int):void {
if (!gridData)
     gridData = new XMLListCollection();
for (var j:int=0; j < rowNum; j++) {                   
    for (var i:int=0; i < colNum; i++) {                  
          // WHAT should be here to initialize every element of XMLListCollection ???         
         //gridData.addItem({<row><A/><B/><C/><D/><E/></row>}); // that obviously doesn't work  
grid.dataProvider = dataGrid;
this.addChild(grid);         
TIA,
Oleg.

Answer 1

To answer my question the initialization loop should be something like that:
for (var j:int=0; j < rowNum; j++) {
      rowXML = <row/>;
      for (var i:int=0; i < colNum; i++) {    // init each DG cell to "" (i.e. like: <A/>)                      
          rowXML.appendChild(new XML("<"+colNames[i]+"/>"));
     gridData.addItem(rowXML);
Thanks,
Oleg.
