Load content form XML to new Column

Hi,

Is it possible to load data from a xml file to a new column ?
Here is my issue :

I have a treegrid with 3 columns, when I expand a node, I would like to add a column and load the content of the new column with a xml file.

mygrid = new dhtmlXGridObject('gridbox');
mygrid.setHeader("col1, col2, col3");
mygrid.attachEvent("onOpenEnd",addColumnAfterExpand);
mygrid.attachEvent("onOpenStart",hideColumnAfterExpand);
mygrid.loadXML("bdd/test.xml");
var newColId = 3;
function addColumnAfterExpand(id, state){
	if (state == true){
		if(mygrid.isColumnHidden(newColId))
			mygrid.setColumnHidden(newColId,false);
		else {
			mygrid.insertColumn(newColId+1,"col4","ed",120,"na","left","top","","");
			//here I would like to load the content for my new column
			//from an xml File
		}	
	}
	mygrid.setSizes();
	return true;
}
function hideColumnAfterExpand(id, state){
	if (state == true){
		mygrid.setColumnHidden(newColId,true);
	}
	mygrid.setSizes();
	return true;
}

If someone has an idea ?

Thanks.

Unfortunately such feature is not available.
dhtmlxgrid is an row-oriented component.
