[xsl] Transformation Grouping Problem (XSLT 2.0, Saxon-PE 9.3.0.5)

[Raymond Lillibridge <RLillibridge@xxxxxxxxxxxx>]

Good Day to all!

I'm in need of some assistance with group logic using XSLT 2.0.


Given the following sample xml file as input:

<book>
            <title>My Book Title</title>

            <para>book Blah, blah, blah</para>
            <para>book Dah, dah, dah</para>
            <para>book Lah, lah, lah</para>

            <level1>
                        <title>level1 AAA</title>
                        <para>level1 Blah, blah, blah</para>
                        <para>level1 Dah, dah, dah</para>
                        <para>level1 Lah, lah, lah</para>

                        <level2>
                                    <title>level2 AAA</title>
                                    <para>level2 Blah, blah, blah</para>
                                    <para>level2 Dah, dah, dah</para>
                                    <para>level2Lah, lah, lah</para>

                                    <level3>
                                                <title>level3 AAA</title>
                                                <para>level3 Blah, blah, bl=
ah</para>
                                                <para>level3 Dah, dah, dah<=
/para>
                                                <para>level3 Lah, lah, lah<=
/para>
                                    </level3>

                                    <level3>
                                                <title>level3 AAA</title>
                                                <para>level3 Blah, blah, bl=
ah</para>
                                                <para>level3 Dah, dah, dah<=
/para>
                                                <para>level3 Lah, lah, lah<=
/para>
                                    </level3>

                        </level2>
            </level1>
</book>


using 'for-each-group'  I can group by the different levels, but how can I =
isolate just the 'top' content of the <book> or  <level#>?

For instance, I'd like to create an XML result-document that contains only:

<book>
            <title>My Book Title</title>

            <para>book Blah, blah, blah</para>
            <para>book Dah, dah, dah</para>
            <para>book Lah, lah, lah</para> </book>


...and another XML result-document that contains only:

<level1>
            <title>level1 AAA</title>
            <para>level1 Blah, blah, blah</para>
            <para>level1 Dah, dah, dah</para>
            <para>level1 Lah, lah, lah</para> </level1>

...&c.
