       db2x_xsltproc - XSLT processor invocation wrapper


       db2x_xsltproc [options] xml-document


       db2x_xsltproc invokes the XSLT 1.0 processor for docbook2X.

       This command applies the XSLT stylesheet (usually given by the --stylesheet option) to the
       XML document in the file xml-document.  The result is written to standard  output  (unless
       changed with --output).

       To read the source XML document from standard input, specify - as the input document.


              Display the docbook2X version.

       --output file, -o file
              Write output to the given file (or URI), instead of standard output.

       --xinclude, -I
              Process XInclude directives in the source document.

       --sgml, -S
              Indicate  that  the  input document is SGML instead of XML.  You need this set this
              option if xml-document is actually a SGML file.

              SGML parsing is implemented by conversion  to  XML  via  sgml2xml(1)  from  the  SP
              package (or osx(1) from the OpenSP package). All tag names in the SGML file will be
              normalized to lowercase (i.e. the  -xlower  option  of  sgml2xml(1)  is  used).  ID
              attributes  are  available  for the stylesheet (i.e. option -xid). In addition, any
              ISO SDATA entities used in the SGML document are automatically converted  to  their
              XML Unicode equivalents. (This is done by a sed filter.)

              The  encoding  of  the SGML document, if it is not us-ascii, must be specified with
              the standard SP  environment  variables:  SP_CHARSET_FIXED=1  SP_ENCODING=encoding.
              (Note  that  XML  files  specify  their  encoding  with  the  XML declaration <?xml
              version="1.0" encoding="encoding" ?> at the top of the file.)

              The above conversion options cannot be changed. If you desire different  conversion
              options,  you should invoke sgml2xml(1) manually, and then pass the results of that
              conversion to this program.

       --catalogs catalog-files, -C catalog-files
              Specify additional XML catalogs to use for resolving Formal Public  Identifiers  or
              URIs. SGML catalogs are not supported.

              These  catalogs  are not used for parsing an SGML document under the --sgml option.
              Use the environment variable SGML_CATALOG_FILES instead to specify the catalogs for
              parsing the SGML document.

       --network, -N
              db2x_xsltproc will normally refuse to load external resources from the network, for
              security reasons.  If you do want to load from the network, set this option.

              Usually you want to have installed locally the relevent DTDs and other  files,  and
              set up catalogs for them, rather than load them automatically from the network.

       --stylesheet file, -s file
              Specify the filename (or URI) of the stylesheet to use.  The special values man and
              texi are accepted as abbreviations, to specify that xml-document is in DocBook  and
              should be converted to man pages or Texinfo (respectively).

       --param name=expr, -p name=expr
              Add  or  modify  a parameter to the stylesheet.  name is a XSLT parameter name, and
              expr is an XPath expression that evaluates to the desired value for the  parameter.
              (This  means that strings must be quoted, in addition to the usual quoting of shell
              arguments; use --string-param to avoid this.)

       --string-param name=string, -g name=string
              Add or modify a string-valued parameter to the stylesheet.

              The string must be encoded in UTF-8 (regardless of the locale character encoding).

       --debug, -d
              Display,  to  standard  error,  logs  of  what  is   happening   during   the   XSL

       --nesting-limit n, -D n
              Change  the  maximum  number  of  nested  calls  to  XSL  templates, used to detect
              potential infinite loops.  If not specified, the limit is 500 (libxslt’s default).

       --profile, -P
              Display profile information: the total number of calls  to  each  template  in  the
              stylesheet  and  the  time  taken  for each. This information is output to standard

       --xslt-processor processor, -X processor
              Select the underlying XSLT processor used. The possible choices for processor  are:
              libxslt, saxon, xalan-j.

              The  default  processor  is  whatever was set when docbook2X was built.  libxslt is
              recommended (because it is lean and fast), but SAXON is much more robust and  would
              be more helpful when debugging stylesheets.

              All  the  processors  have  XML catalogs support enabled.  (docbook2X requires it.)
              But note that not all the options above work with processors other than the libxslt


              Specify XML Catalogs.  If not specified, the standard catalog (/etc/xml/catalog) is
              loaded, if available.

              Specify the XSLT processor to use.  The effect is the same as the  --xslt-processor
              option.  The primary use of this variable is to allow you to quickly test different
              XSLT processors without having to add --xslt-processor to every script or make file
              in your documentation build system.


       XML  Stylesheet Language – Transformations (XSLT), version 1.0 ⟨⟩
       , a W3C Recommendation.


       In its earlier versions  (<  0.8.4),  docbook2X  required  XSLT  extensions  to  run,  and
       db2x_xsltproc was a special libxslt-based processor that had these extensions compiled-in.
       When the requirement for XSLT extensions was dropped, db2x_xsltproc became a  Perl  script
       which  translates  the  options  to db2x_xsltproc to conform to the format accepted by the
       stock xsltproc(1) which comes with libxslt.

       The prime reason for the existence of this  script  is  backward  compatibility  with  any
       scripts  or  make  files  that  invoke  docbook2X.  However, it also became easy to add in
       support for invoking other XSLT processors with a unified command-line interface.  Indeed,
       there  is  nothing  special in this script to docbook2X, or even to DocBook, and it may be
       used for running other sorts of stylesheets if you desire. Certainly  the  author  prefers
       using  this  command,  because  its invocation format is sane and is easy to use. (e.g. no
       typing long class names for the Java-based processors!)

       The docbook2X manual (in Texinfo or HTML format) fully describes how to convert DocBook to
       man pages and Texinfo.

       You may wish to consult the documentation that comes with libxslt, SAXON,  or  Xalan.  The
       W3C XSLT 1.0 specification would be useful for writing stylesheets.
