Re: Node Position & Relationship!

Hi Adam,
  I'll try to answer your question in parts..

q1) to create an xsl if element that tests the current
node to see if it is a level 0 tree_node element.
Ans -
<xsl:if test="self::tree_node and
not(parent::tree_node)">

</xsl:if>
If you are at a given node, this if condition
evaluates true if the node is at level 0(i.e., if it
is a tree_node element, and it has no tree_node
parent)

In the XML you gave, this condition will be true for
<tree_node id="7" value="Test"> node..

q2) how can I find out if a particular node is a
child, ancestor or peer of any given node.
Ans - Suppose node X is the context node, and there is
another node Y ;
X is child of Y, if this condition is true
<xsl:if test="parent::Y">

</xsl:if>

Y is an ancestor of X, if this condition is true
<xsl:if test="ancestor::Y">

</xsl:if>

Y is peer of X(following or preceding sibling), if
this condition is true
<xsl:if test="(following-sibling::Y) or
(preceding-sibling::Y)">

</xsl:if>

Mukul
