Oh, and to start from scratch, do: var _xml:XML = <root>;
then: var xmlNode:XML = <node>; [EMAIL PROTECTED] = "somevalue"; _xml.appendChild(xmlNode) Shold give you: <root> <node attr="somevalue" /> </root> ________________________________ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Tracy Spratt Sent: Wednesday, April 04, 2007 9:57 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Re: Tree and Array The main method you will be using is appendChild().

In other langauges i usually use methods to do it .. like: Tree.AddItem(Key, Item, Parent) or set Node = GetNode(parent) Node.AddChild(key, item) so, what i need.. are these methods in flex. How can i add data to a tree control? i know that i have to first prepare a dataprovider and that i can't work directly with the tree control, and you told me to use e4x.. so ok... but how? where are the additem() or getparent() or whatever? i saw the manuals for e4x, and found out that its need to manipulate xml files, but all the samples in the manual just show how to delete , add or modify xml data from an existing xml structure. thats not my case... i need to start with an empty xml. hope i've been clear. thanks --- In flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> , "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > You must build either XML, or an ArrayCollection of ArrayCollections. > > > > Are you asking how to construct the logic to read your array and build > the dataProvider? > > > > It will depend on the exact character of the array data.
