This module exports procedures for transforming a limited subset of the SXML representation of docbook into stexi. It is not complete by any means. The intention is to gather a number of routines and stylesheets so that external modules can parse specific subsets of docbook, for example that set generated by certain tools.
"Flatten" a fragment of sdocbook so that block elements do not nest inside each other.
Docbook is a nested format, where e.g. a refsect2 normally
appears inside a refsect1. Logical divisions in the document are
represented via the tree topology; a refsect2 element
contains all of the elements in its section.
On the contrary, texinfo is a flat format, in which sections are marked
off by standalone section headers like @subsection, and block
elements do not nest inside each other.
This function takes a nested sdocbook fragment sdocbook and flattens all of the sections, such that e.g.
(refsect1 (refsect2 (para "Hello")))
becomes
((refsect1) (refsect2) (para "Hello"))
Oftentimes (always?) sectioning elements have <title> as their
first element child; users interested in processing the refsect*
elements into proper sectioning elements like chapter might be
interested in replace-titles and filter-empty-elements.
See replace-titles, and filter-empty-elements.
Returns a nodeset; that is to say, an untagged list of stexi elements. See SXPath, for the definition of a nodeset.
Filters out empty elements in an sdocbook nodeset. Mostly useful after
running sdocbook-flatten.
Iterate over the sdocbook nodeset sdocbook-fragment, transforming
contiguous refsect and title elements into the appropriate
texinfo sectioning command. Most useful after having run
sdocbook-flatten.
For example:
(replace-titles '((refsect1) (title "Foo") (para "Bar.")))
⇒ '((chapter "Foo") (para "Bar."))
