 XSL (from programming point of view) is much like functional languages
therefore the only way you can do it is to recursively call a template.


<xsl:template name="br">
    <xsl:choose>
        <xsl:when test="$n = 0">
            <br/>
         </xsl:when>
         <xsl:otherwise>
             <br/>
             <xsl:call-template name="br">
                 <xsl:with-param name="n"><xsl:value-of select="$n - 1"/></xsl:with-param>
             </xsl:call-template>
         </xsl:otherwise>
   </xsl:choose>
</xsl:template>


<xsl:template match="somexmltag">

<xsl:call-template name="br">
    <xsl:with-param name="n"><xsl:value-of select="./@someattr"/></xsl:with-param>
</xsl:call-template>

</xsl:template>
