Try this XSLT:

  <xsl:output indent="yes"/>

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

  <xsl:template match="version">
    <xsl:copy>
      <xsl:apply-templates select="*"/>
      <xsl:apply-templates select="document('file1.xml')/config/version/*" />
    </xsl:copy>
  </xsl:template>
