4 months ago The build file expects only one output file, but with footnotes, we get separate HTML file for each footnote by default. So each footnote overwrites the .mml file. Footnotes can be put to the main HTML file using the "fn-in" option, but it can be a good idea to support multiple files anyway.
This build file appends MathML code from all generated HTML files:
local domfilter = require "make4ht-domfilter"
local mkutils = require "mkutils"
local process = domfilter {"mathmlfixes", -- fix mathml first
function(dom, par)
-- if we output to several HTML files, we want to overwrite the mml file in the first processed
-- file, in the following files, we will append MathML to the already existing file
local current_name = mkutils.remove_extension(par.filename)
local mode = "a"
if current_name == par.input then mode = "w" end
local filename = par.input .. "-mathml.mml"
local f = io.open(filename, mode)
for count, math in ipairs(dom:query_selector "math") do
f:write("\n"..count.."\n")
f:write(math:serialize())
end
f:close()
return dom
end
}
Make:match("html", process)

I'm trying to extract all the mathml into an extra file. Based on https://chat.stackexchange.com/transcript/41?m=65070731#65070731 I tried with this extract-math.mk4:
I then call it for test-utf8.tex with
make4ht -l -e extract-math.mk4 test-utf8 "mathml"This works fine for
and the files contains
But as soon as I uncomment the footnote in the example above the file is empty.
