Untested but try the following approach
<xsl:template match="Categories">
<Categories>
<xsl:apply-templates select="Category[length(string(Code))=1]"
/>
</Categories>
</xsl:template>
<xsl:template match="Category">
<xsl:variable name="code" select="string(Code)"/>
<xsl:variable name="code-length" select="length(string(Code))"/>
<xsl:variable name="name">
<xsl:choose>
<xsl:when
test="length(string(Code))=1">LevelOneCategory</xsl:when>
...etc
</xsl:choose>
</xsl:variable>
<xsl:element name="{$name}" Code="{$code}" Description="{Description}">
<xsl:apply-templates
select="following-sibling::Category[substring(string(Code),1,$code-length)=string($code)]"
/>
</xsl:element>
</xsl:template>
following-sibling:: could be replaced with ../ if the order is not guaranteed.

Subject: [xsl] XML to XML
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!
