[xsl] Trouble digesting grouping

---

---

I'm struggling with a grouping problem. I've had some success with simpler
structures, but this one has me stumped. This is an XML to XML transform.

I need to eliminate the parent <para > completely, output the <table> intact,
but grab the <graphic> elements, create a single <figure>, then a <subfig>
wrapper element for each <graphic>. Then output the structures interspersed
with the tables. I can't seem to separate the tables and figures. What I'm
ending up with is a single <figure> with all the <subfig>, then the tables.


<install>
   <proc>
     <step1>
        <para></para>
</step1>
</proc>
<para>
<table>
         All the table stuff
   </table>
   <graphic>
   <graphic>
   <graphic>
   <table>
        All the table stuff
   </table>
   <graphic>
   <graphic>
   <graphic>
</para>
</install>

Output that I desire:

<install>
   <step1>
     <para></para>
   <step1>
   <table>
      All the table stuff
   </table>
   <figure><title/>
     <subfig><graphic></subfig>
     <subfig><graphic></subfig>
      <subfig><graphic></subfig>
   </figure>
   <table>
      All the table stuff
   </table>
   <figure><title/>
     <subfig><graphic></subfig>
     <subfig><graphic></subfig>
      <subfig><graphic></subfig>
   </figure>
</install>

Output that I'm getting (and I've tried defining the group in various ways,
this is my last iteration).

<install>
   <step1>
      <para></para>
   </step1>
<figure><title/>
   <subfig><graphic/></subfig>
   <subfig><graphic/></subfig>
   <subfig><graphic/></subfig>
   <subfig><graphic/></subfig>
   <subfig><graphic/></subfig>
   <subfig><graphic/></subfig>
</figure>
<table></table>
<table></table>
</install>

My current templates: (Wendell, my apologies for just not getting this). Using
XSLT 2.0.



<install>
   <xsl:apply-templates select="descendant::step1"/>
   <xsl:if test="child::proc/following-sibling::para/(child::table|graphic)">
      <xsl:apply-templates
select="child::proc/following-sibling::para/child::table | child::para"
mode="install"/>
   </xsl:if>
</install>

   <xsl:template match="table" mode="install">
     <table>
     <xsl:apply-templates/>
     </table>
   </xsl:template>

   <xsl:template match="install/para" mode="install">
     <figure>
   <xsl:for-each-group select="*" group-starting-with="graphic">
     <xsl:for-each select="current-group()[self::graphic]">
        <subfig>
           <xsl:copy-of select="."/>
        </subfig>
     </xsl:for-each>
   </xsl:for-each-group>
        </figure>
   </xsl:template>
