you might want to try a recursive template, something like:


<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
	<!--
example call
	-->
	<xsl:template match="/">
		<xsl:call-template name="for-loop">
			<xsl:with-param name="i">5</xsl:with-param>
			<xsl:with-param name="stopat">20</xsl:with-param>
		</xsl:call-template>
	</xsl:template>
	<!--
forloop([i, ]stopvalue)
	-->
	<xsl:template name="for-loop">
		<xsl:param name="stopat" select="50"/>
		<xsl:param name="i" select="1"/>
		<xsl:if test="$i &lt;= $stopat">
			<!-- insert output here -->
			<xsl:value-of select="concat($i, ', ')"/>
			<!-- / -->
			<xsl:call-template name="for-loop">
				<xsl:with-param name="stopat" select="$stopat"/>
				<xsl:with-param name="i" select="$i + 1"/>
			</xsl:call-template>
		</xsl:if>
	</xsl:template>
</xsl:stylesheet>


both params are optional. just insert the output you want at the specified
position.
