Joris,

Thanks heaps for replying. You have pretty much understood and your insight 
i am
sure will be extremely useful and helpful. I have scratch together a 
preliminary style sheet, which output html instead of xml.

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.1" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:param name="css"/>
    <xsl:param name="c_node"/>
    <xsl:param name="url"/>

    <xsl:output method="html" indent="yes"/>

    <xsl:template match="/">
        <table class="{$css}" align="center">
            <xsl:apply-templates /> 
        </table>
    </xsl:template>

    <xsl:template match="node()|@*">
        <tr> 
            <td width="{(@depth + 1) * 20}" align="right">
                <a href="{$url}&node={@id}">+</a>
		</td>
		<td>
		    <xsl:value-of select="@value"/>
		</td>
	  </tr>
	  <xsl:apply-templates 
select="@*|node()[descendant-or-self::*/@id=$c_node]"/>
    </xsl:template>

</xsl:stylesheet>

I don't particularly understand everything that is happening with the xpath 
expression, but i will get there. One problem i face at the moment is that i 
can't seem to output any of the attribute values ie: (@depth,@value). Any 
thoughts why.
Forgive my ignorance.

Cheers,
