SGML

There are various tools to convert SGML into HTML. Here is a an annotated summary of some of them, and here are a few more pointers. Perl filters for several DTDs used in the humanities are available from Michigan and Virginia: see " WWW-to-PAT Gateway; exploiting an SGML-aware system through the Web ". OCLC offers SGML translation services via Fred, which includes tools to translate SGML-tagged text to other formats. Currently, OCLC uses Fred to translate from SGML to HTML, TeX (PostScript), and ASCII.

There are several versions of the HTML DTD: more information is available here. There is also a program dtd2html to convert SGML DTDs themselves to HTML to help browse and understand them.

Linuxdoc-SGML is a text-formatting package based on SGML that will produce HTML as well as other marked up documents.

Conversion of HTML/SGML to other formats is also possible
