Grouping help

Hi All,

 

I have a flat file that I am trying to add some hierarchy to. Here is an
example of the input:

 

<?xml version="1.0" encoding="UTF-8"?>

<root>

   <item level="2" number="A.">General</item>

   <item level="3" number="(1)">This task gives...</item>

   <item level="4" number="(a)">Replace the water...</item>

   <item level="4" number="(b)">Replace the barrier...</item>

   <item level="4" number="(c)">Replace the...</item>

   <item level="3" number="(2)">This task takes...</item>

   <note type="note" position="1">NOTE:</note>

   <note type="note" position="2">Refer to typical...</note>

   <item level="2" number="B.">References</item>

   <item level="2" number="C.">Tools/Equipment</item>

   <note type="note" position="1">NOTE:</note>

   <note type="note" position="2">When more than one...</note>

   <effectivity>Effective on:</effectivity>

   <effectivity>Effective on:</effectivity>

   <item level="2" number="D.">Consumable Materials</item>

   <item level="2" number="E.">Location Zones</item>

   <item level="2" number="F.">Procedure</item>

   <item level="3" number="(1)">Do a check...</item>

   <item level="3" number="(2)">Repair or replace...</item>

   <item level="3" number="(3)">Do this task...</item>

   <item level="3" number="(4)">Do a check...</item>

   <item level="3" number="(5)">Replace the sealant...</item>

   <item level="3" number="(6)">Do a check of...</item>

   <item level="4" number="(a)">Replace the water...</item>

   <item level="4" number="(b)">Replace the barrier...</item>

   <item level="4" number="(c)">Replace the...</item>

   <item level="3" number="(7)">Assemble the...</item>

   <item level="3" number="(8)">Seal all of the...</item>

   <note type="caution" position="1">CAUTION:</note>

   <note type="caution" position="2">MAKE SURE...</note>

   <item level="3" number="(9)">Apply a layer of grease as follows:
<para>Apply a layer of...</para></item>

   <note type="note" position="1">NOTE:</note>

   <note type="note" position="2">The grease can...</note>

   <item level="3" number="(10)">Use the <b>vacuum cups</b> ...</item>

</root>

 

My output is not quite right:

 

<?xml version="1.0" encoding="UTF-8"?>

<task>

   <pretopic lbl="A.">

      <title>General</title>

      <list1>

         <l1item lbl="(1)">This task gives...</l1item>

         <list2>

            <l2item lbl="(a)">Replace the water...</l2item>

         </list2>

      </list1>

   </pretopic>

   <pretopic lbl="B.">

      <title>References</title>

   </pretopic>

   <pretopic lbl="C.">

      <title>Tools/Equipment</title>

      <note type="note" position="1">NOTE:</note>

      <note type="note" position="2">When more than one...</note>

      <effectivity>Effective on:</effectivity>

      <effectivity>Effective on:</effectivity>

   </pretopic>

   <pretopic lbl="D.">

      <title>Consumable Materials</title>

   </pretopic>

   <pretopic lbl="E.">

      <title>Location Zones</title>

   </pretopic>

   <pretopic lbl="F.">

      <title>Procedure</title>

      <list1>

         <l1item lbl="(1)">Do a check...</l1item>

         <l1item lbl="(2)">Repair or replace...</l1item>

         <l1item lbl="(3)">Do this task...</l1item>

         <l1item lbl="(4)">Do a check...</l1item>

         <l1item lbl="(5)">Replace the sealant...</l1item>

         <l1item lbl="(6)">Do a check of...</l1item>

         <list2>

            <l2item lbl="(a)">Replace the water...</l2item>

         </list2>

      </list1>

   </pretopic>

</task>

 

Here is my current stylesheet:

                    <xsl:apply-templates select="." mode="group"/>

                </xsl:otherwise>

            </xsl:choose>

        </xsl:for-each-group>

    </xsl:template>

    

    <xsl:template match="item[@level='4']" mode="group">

    </xsl:template>

    

    <xsl:template match="*" mode="group">

        <xsl:copy-of select="current-group()"/>

    </xsl:template>    

        

</xsl:stylesheet>

 

This example is a modified version of Mike's XHTML version on page 340 of
his book. Any help would be appreciated. Thank you.
