latexml binary package in Ubuntu Jammy armhf

 latexml is a program, written in Perl, that attempts to faithfully mimic
 TeX's behaviour, but produces XML instead of dvi. The document model of
 the target XML makes explicit the model implied by LaTeX.
 .
 The processing and model are both extensible; you can define the mapping
 between TeX constructs and the XML fragments to be created. A postprocessor,
 latexmlpost converts this XML into other formats such as HTML or XHTML,
 with options to convert the math into MathML (currently only presentation)
 or images.
