RE: [docbook-apps] dynamic chunk.section.depth

[Tim Arnold <Tim.Arnold@sas.com>]

Hi David,
That's exactly what I did. In my processing from LaTeX to DocBook, I set a remark with role=toc2 or role=toc3 depending on the tag the writer used. Then, using lxml I do this in python postprocessing of the xml:
----------------------------------------------------------
def set_chunklevel(self, tree):
    for section in tree.xpath('/d:chapter/d:section/d:section',namespaces=xns):
        stop_chunking = etree.ProcessingInstruction('dbhtml', text='stop-chunking')
        remark = section.xpath('child::d:para/d:remark',namespaces=xns)
        if not remark:
            section.insert(0,stop_chunking)
        elif remark[0].get('role') == 'toc2':
           section.insert(0,stop_chunking)
----------------------------------------------------------

so if there is no remark in the 2nd level section I stop chunking.
if there is a remark and it has role=toc2, I stop chunking.
otherwise (there's a remark and it has role=toc3 and so I let it chunk to chunker.section.depth

I was pretty worried about the navigation going haywire, but for my one test of today it looks fine.
I'll google more about it on Monday to see if I'm just getting lucky on this one chapter's navigation.

thanks!
