[xsl] instance a template from xsl:for-each-group

[Andreas Peter <info@xxxxxxxxxx>]

Hello XSL-list,

I want to do a conversion from WordML to Docbook. I have the following 
xsl (as a sample):

<xsl:template match="w:body">
       <chapter>
           <xsl:call-template name="chapter"/>
       </chapter>
   </xsl:template>

   <xsl:template name="chapter">
       <xsl:param name="levelnr" select="1"/>
       <xsl:param name="nodes" select="*"/>
       <xsl:for-each-group select="$nodes"
           
group-starting-with="*[descendant-or-self::*[@w:val=concat('heading',$levelnr)]]">
           <xsl:choose>
               <xsl:when
                   
test="current-group()[descendant-or-self::*[@w:val=concat('heading',$levelnr)]]">
                   <xsl:element name="sect{$levelnr}">
                       <xsl:apply-templates select="node()"/>
                       <xsl:choose>
                           <xsl:when 
test="not(current-group()[position()>1])">
                               <xsl:apply-templates 
select="current-group()"/>
                           </xsl:when>
                           <xsl:otherwise>
                               <xsl:call-template name="chapter">
                                   <xsl:with-param name="levelnr" 
select="$levelnr+1"/>
                                   <xsl:with-param name="nodes" 
select="current-group()[position!=1]"/>
                               </xsl:call-template>
                           </xsl:otherwise>
                       </xsl:choose>
                   </xsl:element>
               </xsl:when>
           </xsl:choose>
       </xsl:for-each-group>
   </xsl:template>

   <xsl:template match="w:p[descendant-or-self::*[@w:val='paragraph']]">
       <para>
           <xsl:apply-templates/>
       </para>
   </xsl:template>

I need to instance the third template from the <xsl:apply-templates 
select="current-group()"/> inside the second template.
I hope this problem could be solved without pasting the source xml -- 
this would be to long (WordML).


Thanks in advance
Andreas
