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 -- You received this message because you are subscribed to the Google Groups "pandoc-discuss" group.
