Given a parameter $num that is the number of copies you want, just have
the template that matches the root node call a named template, passing it
$num. The named template should look like this:

<xsl:template name="MakinCopies">
  <xsl:param name="$num"/>
  <xsl:if test="number($num) &gt; 0">
    <xsl:copy-of select="."/>
    <xsl:if test="number($num) &gt; 1">
      <xsl:call-template name="MakinCopies">
        <xsl:with-param name="num" select="number($num) - 1"/>

It's not really a loop; it's recursion. The number() tests aren't
necessary if you're careful about how you create the first $num; just
being extra careful.
