Lua filter to change the order of a markdown file.

Lua filter to change the order of a markdown file.

Hi all,

First of all, I am quite new to both Pandoc and Lua. So if there are any 
tips you have for getting to know them, they are very welcome.

I am running into a problem while trying to write a Lua filter that would 
change the order of an existing markdown file. This file contains various 
sections (different translations of the same text), divided by headings 
which are followed by paragraphs.

*Example*:
# Heading 1
## Heading 2, source text
Lorem ipsum...

## Heading 2, translation 1
Lorem ipsum...

## Heading 2, translation 2
Lorem ipsum...

I want to be able to change the order of the paragraphs *with* their 
headings. So displaying first the translations and then the source text for 
example. But when I look at the AST, the headers and para(graph)s are 
seperate blocks, so reordering the headers does not copy the corresponding 
paragraphs. 

Can anyone help me out?

Kind regards,
John

Re: Lua filter to change the order of a markdown file.

One approach is to iterate over the list of blocks that makes up the
document body using a for loop, and construct a new list with
a different order.
