RSS question

I am gathering an rss feed from the web and formatting the content using a basic xsl document. (I.e. Basic RSS reader.)

I want to limit the number of results displayed to 5, but I can't find any documentation on how to limit the number of results that are presented.

Here is the code for my .xsl

Any help is greatly appreciated!

<?xml version="1.0" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xslutput method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="*">

<xsl:attribute name="href">
<xsl:value-of select="*[local-name()='channel']/*[local-name()='link']"/>
</xsl:attribute>
<xsl:attribute name="target">

<xsl:value-of select="*[local-name()='channel']/*[local-name()='title']"/>

<xsl:text disable-output-escaping="yes">&nbsp;</xsl:text>
