Converta DublinCore Para MARC

Question

Estou tentando converter o seguinte catálogo XML DublinCore:

<?xml version="1.0" encoding="UTF-8"?>
<articlesinDublinCore xmlns:dc="http://purl.org/dc/elements/1.1/">
<article>
  <dc:creator>Laura Steinert</dc:creator>
  <dc:creator>Ulrich Hoppe</dc:creator>
  <dc:language>English</dc:language>
  <dc:date>2015-09-16</dc:date>
  <dc:title>Using Network Analytics for the Recommendation of Scientific Papers
  </dc:title>
  <dc:format>PDF</dc:format>
  <dc:publisher>Springer</dc:publisher>
  <dc:type>Text</dc:type>
</article>
<article>
<dc:contributor>Nicholas Baloian</dc:contributor>
<dc:contributor>Yasser Zorian</dc:contributor>
  <dc:language>English</dc:language>
  <dc:date>2015-09-16</dc:date>      
  <dc:title>Collaboration and Technology</dc:title>
  <dc:format>PDF</dc:format>      
  <dc:publisher>Springer</dc:publisher>
  <dc:type>Collection</dc:type>
</article>
</articlesinDublinCore>

para um catálogo MARC usando o arquivo oficial XLST da seguinte forma:

    

<xsl:template match="/">
    <record xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </datafield>
        </xsl:for-each>
    </record>
</xsl:template>

O arquivo convertido resultante está acumulando todos os elementos em dois artigos em um único registro, como segue (estou citando apenas uma parte dele):

<?xml version="1.0" encoding="utf-8"?>
<record xmlns="http://www.loc.gov/MARC21/slim"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.loc.gov/MARC21/slim              http://www.loc.gov/standards/marcxml/schema/MARC21slim.xsd">
<datafield tag="042" ind1=" " ind2=" ">
<subfield code="a">dc</subfield>
</datafield>
<datafield tag="720" ind1="0" ind2="0">
  <subfield code="a">Nicholas Baloian</subfield>
  <subfield code="e">collaborator</subfield>
</datafield>
<datafield tag="720" ind1="0" ind2="0">
  <subfield code="a">Yasser Zorian</subfield>
  <subfield code="e">collaborator</subfield>
</datafield>
</record>

No entanto, o que eu preciso é converter a coleção de elementos em DoublineCore em uma coleção de elementos no formato MARC. Alguém tem uma idéia de como eu posso editar a expressão XPATH no arquivo XLST (segundo bloco de código) para obter o resultado desejado?

Obrigado antecipadamente.
