Bts2006 r2 loop question (parent/child)

Question

I need a resultxml that loops over a childrecord and if there is no childrecord there over the parentrecord/
Can this be done using the mapper or do i need to use XSLT?
Sourcesample
<BOMLine>
<BOMQty>48.0000</BOMQty>
<ItemId>Item1</ItemId>
<BOMReference>
<Qty>23.0000</Qty>
<Reference>Ref1</Reference>
</BOMReference>
<BOMReference>
<Qty>25.0000</Qty>
<Reference>ref2</Reference>
</BOMReference>
</BOMLine>
<BOMLine>
<BOMQty>48.0000</BOMQty>
<ItemId>Item2</ItemId>
</BOMLine>
<BOMLine>
<BOMQty>24.0000</BOMQty>
<ItemId>Item3</ItemId>
<BOMReference>
<Qty>24.0000</Qty>
<Reference>ref3</Reference>
</BOMReference>
</BOMLine>
Desired result
<ResultBOM>

<ItemId>Item1</ItemId>
<Reference>Ref1</Reference>
</ResultBOM>
<ResultBOM>
<Qty>25</Qty>
<ItemId>Item1</ItemId>

If you prefer xslt, I tested below for you and works as you needs:
<Root>
<xsl:for-each select="/Root/BOMLine">
<xsl:variable name="var:itemID" select="ItemId/text()" />
<xsl:if test="not(BOMReference)">
<ResultBOM>
<xsl:variable name="var:qty" select="BOMQty/text()" />
<Qty>
<xsl:value-of select="$var:qty" />
</Qty>
<ItemId>
<xsl:value-of select="$var:itemID" />
</ItemId>
<Reference/>
</ResultBOM>
</xsl:if>
<xsl:if test="BOMReference">
<xsl:for-each select="BOMReference">
<ResultBOM>
<Qty>
<xsl:value-of select="Qty/text()" />
</Qty>
<ItemId>
<xsl:value-of select="$var:itemID" />
</ItemId>
<Reference>
<xsl:value-of select="Reference" />
</Reference>
</ResultBOM>
</xsl:for-each>
</xsl:if>
</xsl:for-each>
</Root>
FYI: I assumed "Root" because your XML above doesn't have a root.
