I am trying to make a Lua filter that will replace t= he normal link text in internal links with section numbers. I want to use i= nternal links in my markdown document like this:

&= nbsp; See the [Quick introduction].
=

So, the links are given by the full title of the respec= tive section they refer to. I found a recipe at stackoverflow (https://stac= koverflow.com/questions/54128461/how-to-use-latex-section-numbers-in-pandoc= -cross-reference) which does this if the link is given like this:

  See the [](#quick-introdu= ction)

This is the Lua code:

=
local make_sections =3D (require 'pandoc.= utils').make_sections
local section_numbers =3D {}

function popul= ate_section_numbers (doc)
  function populate (elements)
  =   for _, el in pairs(elements) do
      if el.t =3D= =3D 'Div' and el.attributes.number then
        sect= ion_numbers['#' .. el.attr.identifier] =3D el.attributes.number
  &= nbsp;     populate(el.content)
      end
&nb= sp;   end
  end
  populate(make_sections(true, nil, do= c.blocks))        
end

function resolve_= section_ref (link)
  if #link.content > 0 or link.target:sub(1, = 1) ~=3D '#' then
    return nil
  end
  local = section_number =3D pandoc.Str(section_numbers[link.target])
  retur= n pandoc.Link({section_number}, link.target, link.title, link.attr)
end<= br>
return {
  {Pandoc =3D populate_section_numbers},
  = {Link =3D resolve_section_ref}
}


While I do understand what it does, I cannot fin= d out how to change it to my case. How can I retrieve the part written in [= ] instead of the attributes when scanning the document for those internal l= inks? Or is the not even possible? 

Any idea = is appreciated.
