[Libreoffice] fdo#42924: needs help with "tablehead" xml parsing

[Korrawit Pruegsanusak]

Hello Jan, all,

Following https://bugs.freedesktop.org/show_bug.cgi?id=42924,
this is an unfinished patch to check whether <tablecell> is empty.
Hope I was on the right way :)

Anyway, as commented in the code, how can I detect whether that row is
"tablehead" or not? Currently I just set role = tablecontent.
See http://cgit.freedesktop.org/libreoffice/help/tree/helpcontent2/source/text/scalc/01/04060107.xhp#n219
as an example.
The first tablecell (line 221-222) is empty.
Next 3 are with <paragraph role="tablehead" ...>
If I take an approach like in the patch, the first one won't be
"tablehead", and formatting will be a bit incorrect.
But IMHO the xml parser can't get back to parsed element, right?
So, suggestions are appreciated.

Or, will we take another approach by fixing the help file instead?

Thanks :)
