[xsl] toc with number with element selection

Hi all,

I would like to build a toc using xsl:number (version 2.0 with saxon) avoiding element with pdf="no" attributes. The first group element always has pdf="no" attribute. Other group elements can have this attribute or not.

Data are as follows:
----------------------------
<?xml version="1.0" encoding="UTF-8"?>
<workshop>
 <meta>
  <title><line>t</line></title>
  <image path="t.jpg"
   author="p" />
  <identification>t</identification>
 </meta>
 <body>
  <base>f</base>
  <group pdf="no">
   <reference>a</reference>
   <group>
    <reference>a/b</reference>
    <group>
     <reference>a/b/c</reference>
     <group>
      <reference>a/b/c/d</reference>
     </group>
     <group>
      <reference>a/b/c/e</reference>
     </group>
    </group>
   </group>
   <group>
    <reference>a/f</reference>
    <group>
     <reference>a/f/g</reference>
     <group>
      <reference>a/f/g/h</reference>
     </group>
    </group>
    <group pdf="no">
     <reference>a/f/i</reference>
     <group>
      <reference>a/f/i/j</reference>
     </group>
    </group>
   </group>
  </group>
 </body>
</workshop>

my attempt :
-----------------

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns:pf="http://www.pimeca.com/pf"; xmlns:fn="http://www.w3.org/2005/xpath-functions";>

<xsl:output encoding="UTF-8" method="xml" omit-xml-declaration="no" indent="yes" />

 <xsl:template match="/workshop">
  <r>
   <xsl:apply-templates select="body" />
  </r>
 </xsl:template>

<xsl:template match="meta" />

 <xsl:template match="body">
  <xsl:apply-templates select="group" />
 </xsl:template>

<xsl:template match="group[not(@pdf)]"> <xsl:variable name="p-number"> <xsl:number count="group[not(@pdf)]" level="multiple" format="1.1 " from="/workshop/body/group[@pdf='no']" /> </xsl:variable> <g> <p> <xsl:value-of select="$p-number" /> <xsl:value-of select="./reference" /> </p> <xsl:apply-templates /> </g> </xsl:template>

 <xsl:template match="group[@pdf='no']">
  <xsl:apply-templates select="group" />
 </xsl:template>

 <xsl:template match="reference">
 </xsl:template>

</xsl:stylesheet>

Incorrect result obtained:
---------------------------------

?xml version="1.0" encoding="UTF-8"?>
<r>
   <g>
      <p>1 a/b</p>

      <g>
         <p>1.1 a/b/c</p>

         <g>
            <p>1.1.1 a/b/c/d</p>

         </g>
         <g>
            <p>1.1.2 a/b/c/e</p>

         </g>
      </g>
   </g>
   <g>
      <p>2 a/f</p>

      <g>
         <p>2.1 a/f/g</p>

         <g>
            <p>2.1.1 a/f/g/h</p>

         </g>
      </g>
      <g>
*<p>2.1 a/f/i/j</p>*

     </g>
   </g>
</r>

I would like to obtain 2.2 for a/f/i/j element instead of 2.1. I could not figure out how to do it.

Could you please tell me how to do it with xsl:number or point me to another solution ?

Regards
