Thanks for the pointers Albert! It did help me get started. Unfortunately when I started looping through the Plain object, I realized that the individual strings were represented as separate elements so there did not seem to be an easy way to apply a strikethrough formatting for the entire sentence. The best I would be able to do was apply the strikethrough word-by-word but with that approach, the final HTML did not look very pleasing.

This is an interesting case because it is more complex than it seems.
The reason is pandoc's `task_list` extension that causes pandoc to
handle these checkboxes specially, converting them to [Str "☐", Space]
and [Str "☒", Space]. So we'll have to match on that in our filter.
A good approach would be to write a filter for Plain, like so:
``` lua
function Plain (plain)
-- modify the object here
return plain
end
```
Pandoc will then do all necessary document traversals automatically,
the function gets applied to all `Plain` elements in the document.
To check for the prefix, we'd do something like
``` lua
local done_marker = pandoc.List{pandoc.Str '☒', pandoc.Space()}
local prefix = pandoc.List{plain.content[1], plain.content[2]}
if prefix == done_marker then
-- modify content
end
```
I hope that's enough to get you started. Happy hacking!
