Hi all,



I have been looking at this for too long now,
and I am still not sure why this doesn't work

I have an XML (stripped down version of a word XML document)
That requires (nested) grouping, based on the text content of some paragraphs.

        <wx:sect>
            <wx:sub-section>
                    <w:p>
                        <w:r><w:t>Text before first pgroup</w:t></w:r>
                    </w:p>
                    <w:p>
                        <w:r><w:t>[start pgroup id="43210023"</w:t></w:r>

                    <w:p>
                        <w:r><w:t>First P after nested group</w:t></w:r>

                    </w:p>
                    <w:p>
                        <w:r><w:t>Other In between</w:t></w:r>
                    </w:p>
                    <w:p>
                        <w:r><w:t>[start pgroup id="43210025"</w:t></w:r>
                    </w:p>

                        <w:r><w:t>[start pgroup id="54320026"</w:t></w:r>
                    </w:p>

                        <w:r><w:t>[end pgroup id="54320026"</w:t></w:r>
                    </w:p>
                    <w:p>
                        <w:r><w:t>[end pgroup id="43210025"</w:t></w:r>
                    </w:p>
            </wx:sub-section>
        </wx:sect>
    </w:body>
</w:wordDocument>

groups have IDs and based on these IDs I decide what the pseudo end 
tag of a group is

The result should be something along these lines

The following doesn't work

I don't understand why the current-group() that I pass back to the 
named template

does not behave as nodeset of its members

Or maybe I am just overlooking something



Anyone an idea on this?



Thanks
