I'm using XSLT to style the data in an RSS Feed and I want to limit the number of rows returned:


<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:feedburner="http://rssnamespace.org/feedburner/ext/1.0" xmlns:atom10="http://www.w3.org/2005/Atom">

<xsl:output method="html" encoding="utf-8"/>

<xsl:template match="/">

<img src="{rss/channel/image/url}" />

<br />

<xsl:for-each select="rss/channel/item">

  <a href="{rss/channel/item/feedburner:origLink}"><xsl:value-of select="title"/></a> <br />

  <xsl:value-of select="description" disable-output-escaping="yes"/>

</xsl:for-each>
 

</xsl:template>

</xsl:stylesheet>

I'm sorry, the experts-exchange's text editor replaced a '& lt;' with a '<',
see the code snippet below, hope it will remain as is

select="rss/channel/item[position()&lt;4]"

That kinda works, but <4 just returns 2 results - I have to do <7 to return 5 rows :~

Ok, I agree, position() < 4 return 3, but you said it returns only 2? Weird...

Should select the first 4 items:
<xsl:for-each select="rss/channel/item[position() &lt;= 4]">
