Tim,

I hope that you're still alive and well. :-)

I could not find the problem in your stylesheet fragment.

Perhaps the following stylesheet, which does not use any
extensions, would help you. The output is text rather
than HTML. I tested it using SAXON and your sample XML doc.

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

	<xsl:output method="text"/>

	<xsl:strip-space elements="*"/>

	<xsl:param name="keywords"/>

	<xsl:variable name="a_z" select="'abcdefghijklmnopqrstuvwxyz'"/>
	<xsl:variable name="A_Z" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>

        <xsl:variable name="keywords_lower_case"
		select="translate(	$keywords,
				 	$A_Z,
				 	$a_z )" />

	<xsl:template match="/">
		<xsl:apply-templates/>
	</xsl:template>

	<xsl:template match="detail">
		<xsl:variable name="found_keyword">
			<xsl:call-template name="find_keyword">
				<xsl:with-param name="string"
					select="translate( ., $A_Z, $a_z )"/>
				<xsl:with-param name="keywords"
					select="$keywords_lower_case"/>
			</xsl:call-template>
		</xsl:variable>
		<xsl:if test="$found_keyword = 'yes' ">
			<xsl:text>Found a keyword in '</xsl:text>
			<xsl:value-of select="."/>
			<xsl:text>'&#x0A;</xsl:text>
		</xsl:if>
	</xsl:template>

	<xsl:template name="find_keyword">
    		<xsl:param name="string"/>
    		<xsl:param name="keywords"/>

		<!-- Returns 'yes' if $string contains a keyword.
		     Returns 'no' if $string does not contain any keywords.
		-->

		<xsl:variable name="keyword">
			<xsl:choose>

			<xsl:when test="contains( $keywords, ' ' )">
        			<xsl:value-of
				  select="substring-before($keywords,' ')"/>
			</xsl:when>

			<xsl:otherwise>
        			<xsl:value-of select="$keywords"/>
			</xsl:otherwise>

			</xsl:choose>
		</xsl:variable>

    		<xsl:choose>

        	<xsl:when test="$keyword != '' ">
			<xsl:choose>

			<xsl:when test="contains( $string, $keyword )">
				<xsl:value-of select="'yes'"/>
			</xsl:when>

        		<xsl:otherwise>
				<xsl:variable name="remaining_keywords"
				  select="substring-after( $keywords, ' ' )"/>

				<xsl:call-template name="find_keyword">
					<xsl:with-param name="string"
						select="$string"/>
					<xsl:with-param name="keywords"
						select="$remaining_keywords"/>
				</xsl:call-template>
        		</xsl:otherwise>

			</xsl:choose>
       		</xsl:when>

        	<xsl:otherwise>
			<xsl:value-of select="'no'"/>
        	</xsl:otherwise>

    		</xsl:choose>
	</xsl:template>

	<xsl:template match="text()"/>

</xsl:stylesheet>

Best regards,

Bob
