[flexcoders] create empty folder in a tree

[xvirus001]

My question si simple. Can I create an empty folder in a tree.

Imagine I get a data like this. 
Can I associate the bracket Folder to a folder and the bracket Item to 
an Item. ?

<infos default="">
        <info title="">
                <folder title="">
                <folder title="" />
                        <item title="" />
                        <folder title="" />
                </folder >
                <item title="" />
        </info >
</infos >
