[xsl] XML to XML

[Jim Han <jhan@xxxxxxxxxxxxxxxx>]

I need some help in writing xsl to transform XML to XML.
I am getting lost in concepts of having multiple templates

Original:
<Categories>
	<Category>
		<Code>A</Code>
		<Description>Airplanes</Description>
	</Category>
	<Category>
		<Code>AA</Code>
		<Description>Airplanes (ARF)</Description>
	</Category>
	<Category>
		<Code>AAE</Code>
		<Description>Airplanes (ARF), Electric</Description>
	</Category>
	<Category>
		<Code>AAG</Code>
		<Description>Airplanes (ARF), Giant</Description>
	</Category>
	<Category>
		<Code>AAP</Code>
		<Description>Airplanes (ARF), Sailplane</Description>
	</Category>
	<Category>
		<Code>B</Code>
		<Description>Boats</Description>
	</Category>
	<Category>
		<Code>BA</Code>
		<Description>Boats (ARF)</Description>
	</Category>
	<Category>
		<Code>BAE</Code>
		<Description>Boats (ARF), Electric</Description>
	</Category>
<Categories>


Final Result - where one letter, two letter, and three letter categories are
nested.


<Categories>
	<LevelOneCategory Code="A" Description="Airplanes">
		<LevelTwoCategory Code="AA" Description="Airplanes (ARF)">
			<LevelThreeCategory  Code="AAE"
Description="Airplanes (ARF), Electric"/>
			<LevelThreeCategory  Code="AAG"
Description="Airplanes (ARF), Giant"/>
			<LevelThreeCategory  Code="AAP"
Description="Airplanes (ARF), Sailplane"/>
		</LevelTwoCategory>
      </LevelOneCategory>
	<LevelOneCategory Code="B" Description="Boats">
		<LevelTwoCategory Code="BA" Description="Boats (ARF)">
			<LevelThreeCategory  Code="BAE" Description="Boats
(ARF), Electric"/>
		</LevelTwoCategory>
      </LevelOneCategory>
<Categories>

Thank you!
