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
[http://xsltsl.org] : 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="$text" />
                        </xsl:call-template>
                </xsl:variable>
                <xsl:variable name="test-what">
                        <xsl:call-template name="str:to-lower">
                                <xsl:with-param name="text" select="$what" />
                        </xsl:call-template>
                </xsl:variable>
                <xsl:choose>
                        <xsl:when test="contains($test-text, $test-what)">
                                <xsl:variable name="before" 
select="substring-before($test-text,
$test-what)"/>
                                <xsl:variable name="after" 
select="substring-after($test-text,
$test-what)"/>
                                <xsl:variable name="real-before" 
select="substring($text, 1,
string-length($before))"/>
                                <xsl:variable name="real-after"

string-length($before) + string-length($what) + 1)"/>

select="$real-after"/>
                                        <xsl:with-param name="what" 
select="$what"/>
                                </xsl:call-template>
