NAME - convert DocBook Booksto Texinfo documents


       nsgmls [ sgml document ]| sgmlspl [ basename ]

       docbook2texi is a sgmlspl spec file that produces GNU Texinfo documents
       from DocBook documents.

       The program reads ESIS produced by nsgmls (or other SGML parsers) from
       standard input.  Currently the document element must be Book, otherwise
       the results are undefined.

       Its output, the converted Texinfo document, is written to standard

       The file basename.refs will also be created, which contains all the
       nodes in the document and their immediate 'child' nodes.  As node
       processing always require forward references, docbook2texi must be run
       twice for each document: the first time to build the references, and
       the second to actually generate a valid document.

       The SGMLSpm package from CPAN.  This package includes the sgmlspl
       script that is also needed.

       Trying docbook2man on non-DocBook or non-conformant SGML results in
       undefined behavior. :-)

       This program is a slow, dodgy Perl script.

       This program does not come close to supporting all the possible markup
       in DocBook, and may produce wrong output in some cases with supported

       • How the hell do you represent a backslash (\) in Texinfo!!@?  I've
         tried \\ but TeX complains about it.

       • Fix breakages found in the test documents.

       • Add new element handling and fix existing handling.  Be robust.

       • Make it faster. I think most of the speed problems so far is with
         parsing ESIS.  Rewrite with C and/or get input directly from

       • There are some dependencies on elements occurring when they are
         actually optional (according to the DTD).  We need to fix that
         (preferably) or prominently state the requirements.

       • Allow other more common document elements.

       • Separate out node referencing to a separate script.  Not only would
         it make it faster/easier to maintain because it's separate from the
         main code, but also I would like it to evolve into an automatic
         DocBook ToC generator.
