i want to group elements from differents groups for example

input xml :

<corecom:ShipmentItemInstanceGenealogy>

i want to group them based on corecom:Name and corecom:SerialNumber tag

expected output:

<pasabm:TransactionProductVO>
  <pasabm:ItemNumber>SK1J Serial OPSM item</pasabm:ItemNumber>
  <pasabm:ItemSource>EBIZ_01</pasabm:ItemSource>

  <pasabm:LotSource/>
  <pasabm:LotLocation>M1</pasabm:LotLocation>
  <pasabm:ExpirationDate/>
  <pasabm:TransactionSerialAssocVO>
    <pasabm:ItemSerialNumber>0007</pasabm:ItemSerialNumber>
    <pasabm:SerialType>SGTIN-96</pasabm:SerialType>
    <pasabm:SerialIdentification>715052-0010-S05546-2</pasabm:SerialIdentification>
    <pasabm:ParentSerialIdentification>717048-0002-S07546-1</pasabm:ParentSerialIdentification>

  <pasabm:TransactionSerialAssocVO>
    <pasabm:ItemSerialNumber>0009</pasabm:ItemSerialNumber>
    <pasabm:SerialType>SGTIN-96</pasabm:SerialType>
    <pasabm:SerialIdentification>715052-0009-S05546-2</pasabm:SerialIdentification>

    <pasabm:ShippedItemFlag>0</pasabm:ShippedItemFlag>
  </pasabm:TransactionSerialAssocVO>
</pasabm:TransactionProductVO>

my trial code:

          </pasabm:ExpirationDate>

         <xsl:for-each select="../../corecom:ItemInstanceGenealogyComposition/corecom:ItemReference">

                <pasabm:TransactionSerialAssocVO>

                  </pasabm:ItemSerialNumber>
                  <pasabm:SerialType>
                     <xsl:value-of select='substring-before(../corecom:ItemInstance/corecom:SerialNumber,"/")'/>
                  </pasabm:SerialType>

                     <xsl:value-of select="corecom:ItemIdentification/corecom:ID"/>
                  </pasabm:SerialIdentification>
                  <pasabm:ParentSerialIdentification>
                      <xsl:value-of select="../corecom:ParentItemInstanceGenealogyCompositionIdentification/corecom:ID"/>
                   </pasabm:ParentSerialIdentification>
                   <pasabm:ShippedItemFlag>
                      <xsl:text disable-output-escaping="no">0</xsl:text>
                   </pasabm:ShippedItemFlag>
               </pasabm:TransactionSerialAssocVO>
              </xsl:if> 
           </xsl:for-each>

Here follows an XSLT 2.0 example using for-each-group. Because you have missed some important information in your question (and even because your input sample is huge), I've assumed a simpler input document:
