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($before))"/>
<xsl:variable name="real-after"
select="substring($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:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
Regards,
Alex
