DESCRIPTION
The purpose of xmlto is to convert an XML file to the desired format
using whatever means necessary. This may involve two steps:
1. The application of an appropriate XSL stylesheet using an XSL-T
processor.
2. Further processing with other tools. This step may not be
necessary.
To decide which stylesheet to use and what, if any, needs to be done to
post-process the output, xmlto makes use of format scripts, which are
simple shell scripts that xmlto calls during the conversion.
The appropriate format script is selected based on the type of XML file
and the desired output format. xmlto comes with some format scripts
for converting DocBook XML files to a variety of formats. You may
specify your own format script by using an absolute filename for format
on the command line.
Firstly, if xmlto has not been told explicitly which stylesheet to use
(with the -x option), the format script will be called with $1 set to
stylesheet. The environment variable XSLT_PROCESSOR contains the base
name of the executable that will be used to perform the XSL-T
transformation (for example xsltproc). The format script should write
the name of the stylesheet to use to standard output and exit
successfully, or exit with a non-zero return code if there is no
appropriate stylesheet to use (for example, if the only available
stylesheet is known not to work with the XSL-T processor that will be
used). If nothing is written to standard output but the script exits
successfully, no XSL-T transformation will be performed.
Secondly, after an XSL-T processor has been run using the stylesheet,
the format script will be called again, this time with $1 set to
post-process. The format script should perform any necessary steps to
translate the XSL-T processed output into the desired output format,
including copying the output to the desired output directory. For
post-processing, the format script is run in a temporary directory
containing just the processed output (whose name is stored in
XSLT_PROCESSED and whose basename is that of the original XML file with
any filename extension replaced with .proc). INPUT_FILE is set to the
name of the original XML file, OUTPUT_DIR is set to the name of the
directory that the output (and only the output) must end up in, and
SEARCHPATH is set to a colon-separate list of fallback directories in
which to look for input (for images, for example). If this step is
unsuccessful the format script should exit with a non-zero return code.
OPTIONS
-v
Be verbose (-vv for very verbose).
-x stylesheet
Use stylesheet instead of asking the format script to choose one.
-m fragment
Use the provided XSL fragment to modify the stylesheet.
-o directory
Put output in the specified directory instead of the current
working directory.
-p postprocessor_opts
Pass postprocessor_opts to processing stages after stylesheet
application (e.g. lynx or links when going through HTML to text,
or xmltex when going from through TeX to DVI). If -p is specified a
second time, the options specified will be passed to second-stage
postprocessing; presently this is only applicable when going
through xmltex and dvips to PostScript.
--extensions
Turn on stylesheet extensions for the tool chain in use (for
example, this might turn on passivetex.extensions and
use.extensions if PassiveTeX is being used). The variables turned
on are the ones used by Norman Walsh´s DocBook XSL stylesheets.
--searchpath path
Add the colon-separated list of directories in path as fallback
directories for including input.
--skip-validation
Skip the validation step that is normally performed.
--stringparam paramname=paramvalue
Pass a named parameter paramname with value paramvalue to
stylesheet from the command line.
--noclean
Temporary files are not deleted(their names are shown and kept in
tmp directory). It could help with analyzing problems.
--noautosize
By default, some XSL variables are overriden by autodetection
(page.width and page.height for paperconf (libpaper) use,
paper.type for locale-based (LC_PAPER) selection). With this
option, xmlto doesn’t use this autodetection and user is able to
modify defaults himself (either via default param.xsl modification
or by user-defined XSL fragment).
--with-fop
Use fop for formatting. It is an experimental option, expects fop
in specific location(detected at configured time), could be changed
manually in xmlto script by modification of FOP_PATH
--with-dblatex
Use dblatex for formatting. It is an experimental option, expects
dblatex in specific location(detected at configured time), could be
changed manually in xmlto script by modification of DBLATEX_PATH
--help
Display a short usage message. It will describe xmlto´s options,
and the available output formats.
--version
Display the version number of xmlto.
ENVIRONMENT
XSLT_PROCESSOR
Base name of the executable that will be used to perform the XSL-T
transformation (default: xsltproc(1)).
TMPDIR
Directory, where to create temporary stylesheets (default: /tmp).
DIAGNOSTICS
0
Everything went fine. This is the expected exit code.
1
xmlto was called with insufficient arguments.
2
mktemp(1) failed to create a file/directory. Make sure /tmp or
TMPDIR is writable.
3
xmlto failed to find some binary on configured location. Make sure
that all required packages are installed and paths in xmlto script
are set properly.
10+(Validation non-zero error code)
xmlto tried to validate a xml document, but validation failed. For
better diagnostic, validation output and xmllint exit code is
provided. Consider either fixing your document or using
--skip-validation.
EXAMPLES
To convert a DocBook XML document to PDF, use:
xmlto pdf mydoc.xml
To convert a DocBook XML document to HTML and store the resulting HTML
files in a separate directory use:
xmlto -o html-dir html mydoc.xml
To convert a DocBook XML document to a single HTML file use:
xmlto html-nochunks mydoc.xml
To modify the output using an XSL fragment use:
xmlto -m ulink.xsl pdf mydoc.xml
To specify which stylesheet to use (overriding the one that the format
script would choose) use:
xmlto -x mystylesheet.xsl pdf mydoc.xml
