Still Testing!!

<?xml version="1.0"?>
<tree>
  <tree_node id="7" value="Test">
    <tree_node id="8" value="Test Sub"/>
      <tree_node id="9" value="Test Sub One">
      <tree_node id="10" value="Test Sub Two">
        <tree_node id=11 value=Test Sub Three/>
      </tree_node>
    </tree_node>
  </tree_node>
</tree>

Given the structure above I am trying to use an xsl:if test that tests
whether a node is an immediate child of a particular node. ie: Node with id
8 Is the immediate child of node with id of 7.

<xsl:if test="parent::tree_node[@id=$c_node]">

</xsl:if>

Above is my attempt to achieve this, but doesnt appear to work.

Thanks to those who have responded to my previous posts, I am still very
green to xsl so your insights are appreciated and are slowly helping me
understand this technology.

Cheers,
Adam
