xslt advice? 1

Any ideas on resources that would lead me to the answer to the following:

I have an xml file (which I control so can add attributes etc. as necessary)

Code:

<page id="1" parent=0">
<page id="2" parent=0">
<page id="3" parent=2">
<page id="4" parent=2">
<page id="5" parent=4">
<page id="6" parent=4">
<page id="7" parent=4">
<page id="8" parent=2">
<page id="9" parent=2">
<page id="10" parent=0">
<page id="11" parent=0">
<page id="12" parent=11">
<page id="13" parent=11">
<page id="14" parent=0">
<page id="15" parent=0">

Thus, and example of the full structure indicated above would be:

Code:

As you've probably guessed this is for a left nav! but I need to offer upto three levels where the page ID will drive the transformation (I can certainly access the page ID and am assuming I can use a parameter in the XLST), sucj that:

=> where page ID = 6

Code:

=> where page ID = 12

Code:

=> where page ID = 2

Code:

Any help would be splendid!!!

Thanks.

OK, just for fun...
I warned you it would be easier if the xml is already nested...

Code:

<root>
   <page id="1" parent="0">ONE</page>
   <page id="2" parent="0">TWO</page>
   <page id="3" parent="2">THREE</page>
   <page id="4" parent="2">FOUR</page>
   <page id="5" parent="4">FIVE</page>
   <page id="6" parent="4">SIX</page>
   <page id="7" parent="4">SEVEN</page>
   <page id="8" parent="2">EIGHT</page>
   <page id="9" parent="2">NINE</page>
   <page id="10" parent="0">TEN</page>
   <page id="11" parent="0">ELEVEN</page>
   <page id="12" parent="11">TWELVE</page>
   <page id="13" parent="11">THIRTEEN</page>
   <page id="14" parent="0">FOURTEEN</page>
   <page id="15" parent="0">FIFTEEN</page>
</root>

Code:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="[URL unfurl="true"]http://www.w3.org/1999/XSL/Transform">[/URL]
   <xsl:output method="html" encoding="Windows-1252" />

                              <xsl:value-of select="." />
                           </td>
                        </tr>
                        <xsl:if test="@id=$selectedPage/@id and $insert">
                           <tr>

                              </td>

                        </xsl:if>
                     </xsl:for-each>
                  </table>
               </xsl:with-param>
            </xsl:call-template>
         </xsl:when>

         <xsl:otherwise>

         </xsl:otherwise>

   </xsl:template>
</xsl:stylesheet>
