Hi all,

I'm also trying to highlight a specific word or phrase in the text of
a document.

I've got a word highlighter (it only bolds stuff, but you can put in whatever you need) that is case insensitive and unicode compatible (using str:to-lower function from the xsltsl project [] : replace this with your own lowercaser transformation if you like).

Input is $text (your full text) and $what (what to highlight ; terms,
words, etc.) ;

	<xsl:template name="highlighter">
		<xsl:param name="text"/>
		<xsl:param name="what"/>
		<xsl:variable name="test-text">
			<xsl:call-template name="str:to-lower">
				<xsl:with-param name="text" select="$text" />
		<xsl:variable name="test-what">
			<xsl:call-template name="str:to-lower">
				<xsl:with-param name="text" select="$what" />
			<xsl:when test="contains($test-text, $test-what)">
				<xsl:variable name="before" select="substring-before($test-text,
				<xsl:variable name="after" select="substring-after($test-text,
				<xsl:variable name="real-before" select="substring($text, 1,
				<xsl:variable name="real-after" select="substring($text,
string-length($before) + string-length($what) + 1)"/>
				<xsl:value-of select="$real-before"/>
				<b><xsl:value-of select="$what"/></b>
				<xsl:call-template name="highlighter">
					<xsl:with-param name="text" select="$real-after"/>
					<xsl:with-param name="what" select="$what"/>
				<xsl:value-of select="$text"/>
