Only thing left to do after that is to give each of your bar frames an id. For instance:

<Frame name="DiivSkins_hbar1" id="1" frameStrata="BACKGROUND" inherits="DiivSkins_hbarTemplate" parent="UIParent">
	<Size><AbsDimension x="512" y="46"/></Size>
	<Layers><Layer level="ARTWORK"><Texture name="DiivSkins_hbar1Texture" file="Interface\AddOns\DiivSkins\Skins\diivskins_01"><TexCoords left="0.0019531" right="1.0" top="0.0" bottom="0.0820312"/></Texture></Layer></Layers>
	<Anchors><Anchor point="BOTTOM"><Offset><AbsDimension x="215" y="550"/></Offset></Anchor></Anchors>
<Scripts><OnLoad>this:RegisterEvent("VARIABLES_LOADED");</OnLoad><OnEvent>DS_TextureOnEvent();</OnEvent></Scripts>
</Frame>
