Re: Repeating something "n" times.

[Wendell Piez <wapiez at mulberrytech dot com>]

I like recursion too, but it's true it can be ungainly. To get back to 
Robert's original question

>How do I repeat something 'n' times without a node list with n elements?

Take a node list with more than n elements and use [position() <= $n]....

<xsl:stylesheet version="1.0"
                 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:variable name="elements" select="//*"/>

<xsl:param name="times" select="0"/>

<xsl:template match="/">
   <xsl:call-template name="breaks">
     <xsl:with-param name="times" select="$times"/>
   </xsl:call-template>
</xsl:template>

<xsl:template name="breaks">
   <xsl:param name="times" select="$times"/>
   <xsl:for-each select="$elements[position() &lt;= $times]">
     <br/>
   </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

Note that in the real case you don't need the extra overhead of that 
top-level declaration for $times (this is just for testing).

Cheers,
Wendell

That will be fun.
