Using the FLVPlayback component with Tree

programming flash
1

I try to set content path for FLVPlayback component over the Tree component.
Is possible to use XML file to call and play the FLV file?
I have this XML for Tree component:

<tree>
<folder label= "Flash">
<folder label= "ActioScript">
<link label="Start" url="flv/start.flv">
</link>
</folder>
<folder label= "Design">
<link label="Start" url="flv/design.flv">
</link>
</folder>
</folder>
<folder label= "Flex">
<link label="Instalace" url="flv/flex.flv">
</link>
</folder>
</tree>
