Re: [xsl] Recursive walk up tree

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Dinesh,

The axis you want is the ancestor axis:

<xsl:for-each select="ancestor::*">
  <td>spacer</td>
</xsl:for-each>
<td><xsl:value-of select="@name"/></td>

The ancestor nodes are traversed by the for-each in document order 
(top-down), but since you're only putting out spacers that's okay here.

You can find more about the ancestor and ancestor-or-self axes in any 
decent introduction to XPath location paths (and you should really do this 
before asking hundreds of people on the list).

Good luck,
Wendell
