Hi,

I have a number of markdown files that I concatenate with Pandoc. Each markdown file has a second level top header (##). The markdown files are specified in the variable $document_list.

  pandoc --from=markdown --wrap=auto --to=markdown $documents_list > output.md

In the next step I create a PDF:

  pandoc -f markdown+table_captions --pdf-engine=xelatex --listings -o output.pdf output.md

What I want to do is to filter out certain markdown files in the first step. The filter shall be based on a list under a specific category in the markdown file:

### Group(s)

Category1, Category3

E.g. if Category1 exists in the markdown file I want to filter the entire markdown file out.

Do you think I could achieve this with Lua filters?

Thank you.

/ Henrik
