Works without problem, but when there is a PD node without the attribute "marca" does not appear in the output, that changes must be made in the XSL to display too.

Also if there are two nodes picking in PD, I get two nodes in the output "infocaja", as could choose only the first "infocaja" of node picking.
.....
<femi>01/10/2010</femi>
<infocaja>1/1</infocaja>
<infocaja>2/2</infocaja>

  <xsl:template match="blqcab">
    <xsl:copy>
      <xsl:apply-templates
        select="@* |
                node() |

parent::pbd1/parent::frmbd/following-sibling::picking[1]/pagina/cabecera/infocaja[1]"/>
    </xsl:copy>
  </xsl:template>
