Also, How do I express the following in xsl:

Procedural code begin:

while (count > 0) {
   put <td>
  count--;
}

<xsl:call-template name="do-something">
   <xsl:with-param name="iter" select="10"/>
</xsl:call-template>

<xsl:template name="do-something">
   <xsl:param name="iter" select="0"/>

   <xsl:if test="$iter > 0"
       <xsl:text>foo</xsl:text>
       <xsl:call-template name="do-something">
           <xsl:with-param name="iter" select="$iter - 1"/>
       </xsl:call-template>
   </xsl:if>
</xsl:template>
