This is my xsl:template I am using.
It doesn't appear to work, in that the second condition doesn't cause the
display of the appropriate value.

<xsl:template match="tree_node">
	<xsl:if test="parent::tree or parent::tree_node[@id=$c_node]">
          <xsl:value-of select="@value"/>
      </xsl:if>
	
</xsl:template>

<xsl:template match="tree_node">
<xsl:if test="parent::tree or parent::tree_node[@id='7']">
          <xsl:value-of select="@value"/>
		<xsl:apply-templates/>
</xsl:if>
</xsl:template>

regards,
