[xsl] preserving count function when adding template

[Tom Wern <twern@xxxxxxxxx>]

I have a simple template, see below:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
    <xsl:template match="node">
        <div style="text-indent:{count(ancestor-or-self::node)*2}em">
            <xsl:value-of select="name"/>
        </div>
        <br/>
        <xsl:apply-templates select="node"/>
    </xsl:template>
</xsl:stylesheet>

 that takes a nodeset such as the following:

<node>
    <id>123456789</id>
    <name>COMPANY ABC</name>
    <node>
        <id>456789123</id>
        <name>COMPANY<exist:match>XYZ</exist:match></name>
    </node>
</node>

and simply lists the names, indented corresponding to their nested level. 
In the example above the list would simply be:

COMPANY ABC
      COMPANY XYZ

What my problem is that I would like to add a template of the form:

<xsl:template match="exist:match">
   <span style="background-color: #FFFF00">
    ???
   </span>
</xsl:template>

to the above stylesheet so as to "highlight" in color the term tagged in 
the nodeset with <exist:match>.

How would I integrate this template and what would I specify for ??? to 
accomplish this?

All the variations that I have tried do nothing (I can get highlighting but 
am not able to maintain the indent in the output), but as a newcomer to 
XSLT I've probably missed something obvious. Could someone please point me 
in the right direction?

Thank you.
