...selectedItem.children() returns an error. why?

hi,

I have a Tree komponent which structure is created from an xml file. I want to display/save in XMLList all children nodes and their attributes whenever parent node is selected. I’m trying to use selectedItem with children() but it doesnt work and I get an error value is not a function.

myTree.addEventListener(Event.CHANGE, itemChange);

function itemChange(e:Event):void
{
    
    //var myList:XMLList  = e.target.selectedItem.children();
    trace(e.target.selectedItem.children());
