Highlight words?

Dear all,

I am trying to search and highlight words in XML content displayed as HTML 
using XSLT. I have got the search bit using javascript and dom, and am at 
the moment successfully putting <font> tags around matches when I'm writing 
the results out, by grabbing document.body using dom. However Firefox 
doesn't like it and it is a known bug:

https://bugzilla.mozilla.org/show_bug.cgi?id=325835

I gather that I cannot wait for Firefox to get its act right, so I am 
wondering if there might be an XSLT way to do similar? Pretty much I have 
the search terms fed into a javascript function that does the XSL 
transformation and displays the HTML with the matched keywords highlighted 
using <font color...>. The HTML is generated by XSLT on the fly and Firefox 
won't find document.body this way, if you save the result of the XSLT to a 
file hten load it back in Firefox will see its document.body, however a bug 
exists there it cannot be done at this moment...

What I'm asking is then, I need a way to give the XSLT the keywords to match 
and it'd find them and put <font> tags around each of them when displaying 
them. I currently have :

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="html" encoding="UTF-8" omit-xml-declaration="no" 
doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN" />
 <xsl:attribute-set name="imgAttrs">
  <xsl:attribute name="src">page/<xsl:value-of 
select="@Href"/></xsl:attribute>
 </xsl:attribute-set>
 <xsl:template match="/">
  <html>
   <head>
    <link rel="stylesheet" href="style/template.css" type="text/css" />
   </head>
   <body id="mainBody" style="margin:25px;">
    <xsl:for-each select="//hl1">
     <h3>
      <xsl:copy-of select="."/>
     </h3>
    </xsl:for-each>
    <xsl:for-each select="//body.content/block">
     <p>
      <xsl:copy-of select="."/>
     </p>
    </xsl:for-each>
    <xsl:for-each select="//ContentItem[substring(@Href, 
string-length(@Href) - 3) = '.jpg']">
     <p>
      <xsl:element name="img" use-attribute-sets="imgAttrs"/>
     </p>
    </xsl:for-each>
 <xsl:for-each match="classes">
  <B><xsl:copy-of select="." /></B>
 </xsl:for-each>
   </body>
  </html>
 </xsl:template>
</xsl:stylesheet>

As you can see I'm showing things in a specific order, what I need is for 
each of these for-each results to be matched against the keywords so any 
matches will be transformed into as highlighted.

I'm no expert in XSLT, I know just enough to get by, so if anyone could give 
me some code samples that'd be greatly appreciated... on the other hand if 
anyone knows a way round the Firefox bug please also let me know ...

Many thanks!

Julius
