Re: [xsl] Recursive walk up tree

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

Hi folks,



Can somebody please let me know of an XPATH expression on how to recursively
walk up a tree.

I have a tree of directories in an XML
<directories>
  <directory name=blah>
    <directory name="blee">
      ... to arbitrary depth
    </directory>
  </directory>
</directories>

I need to put each element into a <tr> and a <td> for each level.
<table>
<tr><td>blah</td></tr>
<tr><td>spacer</td><td>blee</td></tr>
<tr><td>spacer</td><td>spacer</td><td>...</td></tr>

</table>
TIA,
Dinesh
