Is there are any way to change Layer's Texture without it's name?

[Nikita S. Doroshenko]

We got simple MerchantRepairItemButton in Blizard MerchantFrame.lua, and this button got Layer with Texture, but without name.

			<Button name="MerchantRepairItemButton">
				<Size x="36" y="36"/>
				<Anchors>
					<Anchor point="RIGHT" relativeTo="MerchantRepairAllButton" relativePoint="LEFT" x="-2" y="0"/>
				</Anchors>
				<Layers>
					<Layer level="BORDER">
						<Texture file="Interface\MerchantFrame\UI-Merchant-RepairIcons">
							<TexCoords left="0" right="0.28125" top="0" bottom="0.5625"/>
						</Texture>
					</Layer>
				</Layers>
				<Scripts>
					<OnEnter>
						...
					</OnEnter>
					<OnClick>
						...
					</OnClick>
				</Scripts>
				<PushedTexture file="Interface\Buttons\UI-Quickslot-Depress"/>
				<HighlightTexture file="Interface\Buttons\ButtonHilight-Square" alphaMode="ADD"/>
			</Button>

I spend a few hours to trying figure out how to change this Texture without knowing it's name, but no luck Maybe someone can help me here. I will very appreciate for your advice.

MerchantRepairItemButton:GetRegions() should give you what you want.
