Behaviour change in docbook reader

Behaviour change in docbook reader

Hello,
I went ahead and upgraded parts of the toolchain since the pandoc version
there was too old (all the way from 2.7.3 to 2.19.2). After that, the
conversion results from docbook to docx were different (granted, I am aware
it's a huge version change). Tracing this, I found one tangible example
that seems to occur in the docbook reader: A <note> element was previously
put into a blockquote pandoc object, now it is a div with an identifying
class.

I am trawling the changelogs for the releases between those two, but would
like to ask the community if you recognize the change offhand and know of
an extension or parameter that lets me revert to the old behaviour while I
identify all those changes and put together some Lua to address it?

docbook:
<note><para>Here is a note without a title</para></note>

Pandoc (-t native) 2.7.3:
BlockQuote
 [Para [Strong [Str "Note"]]
 ,Para [Str "Here",Space,Str "is",Space,Str "a",Space,Str "note",Space,Str
"without",Space,Str "a",Space,Str "title"]]

2.19.2:
Div
    ( "" , [ "note" ] , [] )
    [ Para [ Str "Here", Space, Str "is", Space, Str "a", Space, Str
"note", Space, Str "without", Space
        , Str "a", Space, Str "title"
        ]
    ]

Regards,
Erik Rask

Re: Behaviour change in docbook reader

[John MacFarlane]

With the changelog getting to be book-sized, it’s a big undertaking to look at all the docbook changes since then.
A cleaner approach would be to do a git diff on src/Text/Pandoc/Readers/DocBook.hs from 2.7.3 tag to 2.19.2.

Anyway, a Lua filter to change the 2.19.2 result to the 2.7.3 result should be quite trivial to write (3-4 lines).
