Some SGML authoring +systems (e.g., SoftQuad <i>Author/Editor</i>) have formatting +abilities, and +there are high-end specialist SGML typesetting systems (e.g., Miles33’s +<i>Genera</i>). However, the majority of SGML users probably transform +the source to an existing typesetting system when they want to print. +TeX is a good candidate for this. There are three approaches to writing a +translator: +<ol> +<li> Write a free-standing translator in the traditional way, with + tools like <i>yacc</i> and <i>lex</i>; this is hard, in + practice, because of the complexity of SGML. +<li> Use a specialist language designed for SGML transformations; the + best known are probably <i>Omnimark</i> and <i>Balise</i>. + They are expensive, but powerful, incorporating SGML query and + transformation abilities as well as simple translation. +<li> Build a translator on top of an existing SGML parser. By far + the best-known (and free!) parser is James Clark’s + <i>nsgmls</i>, and this produces a much simpler output format, + called ESIS, which can be parsed quite straightforwardly (one also + has the benefit of an SGML parse against the DTD). Two + good public domain packages use this method: + <ul> + <li> + + David Megginson’s + <a href="http://www.perl.com/CPAN/modules/by-module/SGMLS"><i>sgmlspm</a></i>, + written in <i>Perl</i> 5. + <li> + + Joachim Schrod and Christine Detig’s + <a href="ftp://ftp.tu-darmstadt.de/pub/text/sgml/stil"><i>STIL</a></i>, + (‘SGML Transformations in Lisp’). + </ul> + Both of these allow the user to write ‘handlers’ for every SGML + element, with plenty of access to attributes, entities, and + information about the context within the document tree. +<p/> If these packages don’t meet your needs for an average SGML + typesetting job, you need the big commercial stuff. +</ol> +<p/>Since HTML is simply an example of SGML, we do not need a specific +system for HTML. However, Nathan Torkington developed + +<i>html2latex</i> from the HTML parser in NCSA’s +Xmosaic package. +The program takes an HTML file and generates a LaTeX file from it. +The conversion code is subject to NCSA restrictions, but the whole +source is available on CTAN. +<p/>Michel Goossens and Janne Saarela published a very useful summary of +SGML, and of public domain tools for writing and manipulating it, in +<i>TUGboat</i> 16(2). +<dl> +<dt><tt><i>html2latex source</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/support/html2latex.zip">support/html2latex</a> (<a href="ftp://cam.ctan.org/tex-archive/support/html2latex.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/support/html2latex/">browse</a>) +</dl> +<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=SGML2TeX">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=SGML2TeX</a> +</body> |
