[xsl] Generating book index via attributes...

["Dave Carvell" <dave.carvell@xxxxxxxxx>]

(Using XMLSpy Enterprise Edition version 2010 rel.  2, xsl 1.0)

<?xml version="1.0" encoding="utf-8"?>
<docroot>
    <chapter>
        <title>
            Brakes
            <indxref refs1="Brakes"/>
        </title>
         <subchapter>
            <title>
                Drum type Brakes
                <indxref refs1="Brakes" refs2="drum"/>
            </title>
            <para>stuff...
                <indxref refs1="Brakes" refs2="drum" refs3="diagram"/>
       </para>
       ...

I need to generate an index. For now, I just need a hierarchical listing.

Here is what I get...

Brakes

....drum

........diagram

........terminology

....disc

....failure

........symptoms

........dangers

Engine

....gasoline

....diesel


There is some conflict between entries:

Here is the code. I am very new to this, but it seems to me the difficulty is
due in part to the fact that the attributes are not nested.

<indxref refs1="Brakes" refs2="failure" refs3="symptoms"/>
<indxref refs1="Engine" refs2="failure" refs3="symptoms"/>

I don't get entries for either failures or symptoms under Engine.

Any help would be greatly appreciated.
