LaTeXML is a free public domain software package which converts LaTeX documents to XML, HTML, EPUB, JATS and TEI.

LaTeXML was started in the context of the Digital Library of Mathematical Functions at NIST, where LaTeX documents needed to be prepared for publication on the Web.

[4] As a result of this ongoing effort for enhancing coverage, LaTeXML supports a large range of LaTeX packages.

[10][11] The core of LaTeXML is a Perl reimplementation of TeX's parsing and digestion algorithm coupled with a customizable XML emitter.

The LaTeXML distribution currently provides XML bindings for over 200 commonly used LaTeX packages such as AMSTeX, Babel[12] and PGF/TikZ (which only has experimental support).
