Generating MathML output (eventually for MS Word)

[tvercaut]

I am interested in converting the html generated with lwarp to a Microsoft Word (docx) document (or rather, I am interested in converting latex to MS Word). This can in theory be done by simply opening the html document in MS Word and then saving it as docx or using say pandoc to do the conversion.

Unfortunately, the equations get transformed in "raw latex" in the process (this is using the mathjax option). I tried using \booltrue{FormatWP} but this didn't solve the equation problem.

When using tex4ht ot latexml instead of lwarp (both of which have other issues compared to lwarp), equations are transformed in mathml within the html and these are converted well to MS Word.

Looking at the mathjax equations, there is a right click to show mathml so there must be a standard way to convert to mathml. I couldn't find a command line tool for it though. Is it possible for lwarp to directly output mathml? Or is there a well known tool taht I missed to do this?

P.S.: Sorry for the multiple questions in a few days.
P.P.S.: For the record, my tex4ht+pandoc conversion script can be found here: https://github.com/cai4cai/XCLThesisTemplate/blob/main/tools/convertlatex2word

If you don't mind SVG images you could try FormatWP but without MathJax. In fact I should ensure that MathJax is off if FormatWP is on, or at least issue a warning. I don't think I ever tried it with both on at the same time.

For command-line tools, check:

Thanks. I was hoping to be able to get proper equations in MS Word and found pandoc to be limited in its ability to process latex directly. Hence my attempt to produce html with lwarp first and then get from html to docx with pandoc. Pandoc indeed seems to have some support for mathjax but it doesn't seem to work with an html file produced with lwarp. Could it be due to a non-standard use of mathjax in lwarp or is it more likely to be an issue with how pandoc parses the output of lwarp?

The tex2chtml-page command line tool from MathJax-demos-node seems to do mostly what I wanted. However the equation numbers disappear in the output html from tex2chtml-page. And when I use this as input to pandoc, the generated docx file contains Undefined control sequence \seteqnumber lines.

For the record, I had a related discussion on the pandoc side: jgm/pandoc#9615
I also found that there is a similar option to tex2chtml-page called mjcli used in make4ht.
