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.
