Hello, I am trying to use a word count script so when I display my news items it only displays the first 5 words.
I've found an example to try and modify to work with mine but I'm really stuck. Haven't got a clue where to start. If someone could give me some detailed help it would be really appreciated :D

This is my orginal code so far -

This is the example i've got off the net -
?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="html" indent="yes" />
<xsl:template match="/">
<html>
<head>
<title>Example</title>
</head>
<body>
<h1>Headlines</h1>
<xsl:apply-templates select="headlines/headline" />
</body>
</html>
</xsl:template>
<xsl:template match="headline">
<h2>
<xsl:call-template name="get-words">
<xsl:with-param name="text" select="." />
<xsl:with-param name="number-of-words" select="3" />
</xsl:call-template>
</h2>
</xsl:template>
<xsl:template name="get-words">
<xsl:param name="text" />
<xsl:param name="number-of-words" />
<xsl:param name="processed-words" select="''" />
<xsl:choose>
<xsl:when test="$number-of-words = 0">
<xsl:value-of select="$processed-words" />
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="get-words">
<xsl:with-param name="text"
select="substring-after($text, ' ')" />
<xsl:with-param name="number-of-words"
select="$number-of-words - 1" />
<xsl:with-param name="processed-words"
select="concat($processed-words, ' ', substring-before($text, ' '))" />
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Example input
<headlines>
<headline>Kibology for all. All for Kibology.</headline>
</headlines>
would be transformed as
<html>
<head>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Example</title>
</head>
<body>
<h1>Headlines</h1>
<h2> Kibology for all.</h2>
</body>
</html>
Thanks Kaan.
