copy nodes() of other XML file

Hi all,

I'm trying to copy the contents of a node that is in one file to another, but
must be copied into a document.

XSLT version 1.0

My main XML file:

<?xml version="1.0" encoding="iso-8859-1"?>
<spoolpd>
<pd>
  <frmocs>
    <blqcon>
       <creg>15</creg>
       <czon>1509</czon>
       <csec>B</csec>
    </blqcon>
  </frmocs>
  <frmecc>
     <cab>
       <ccon>0303393</ccon>
       <ncon>MARIA</ncon>
     </cab>
     <detalle>
       <txt>14/09/2010<t/>Saldo anterior a
pagar<tr/>0.00<tr/>0.00<tr/>328.69</txt>
       <txt>30/09/2010<t/>Pago en banco<tr/>0.00<tr/>-328.69<tr/>0.00</txt>

My Second XML File - which should make the information:

<?xml version="1.0" encoding="iso-8859-1"?>
<spoolpd>
<pd>
  <ccon>0303393</ccon>
  <detctacte>

  <detctacte>
    <txt>SALDO ANTERIOR<t/><t/><t/><t/><tr/><tr/><tr/>8901234</txt>
  </detctacte>
</pd>
<spoolpd>

My XSL File:

<?xml version="1.0" encoding="ISO-8859-1"?>

version="1.0">
<xsl:output method="xml" version="1.0" encoding="iso-8859-1" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:param name="f1" select="'VELCTACTE_201010010002.val'"/> <!-- My Second
XML File - which should make the information -->

<xsl:variable name="doc1" select="document($f1)"/>

<xsl:key name="k1" match="spoolpd/pd" use="ccon"/>

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

<xsl:template match="spoolpd">
  <xsl:copy>
    <xsl:apply-templates select="@* | pd"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="pd">
  <xsl:copy>

      <xsl:variable name="id" select="frmecc/cab/ccon"/>
      <xsl:for-each select="$doc1">
        <xsl:copy-of select="key('k1', $id)/detctacte"/>
      </xsl:for-each>
  </xsl:copy>
