.SH "DESCRIPTION"
.PP
The purpose of
\fBxmlto\fR
is to convert an XML
\fIfile\fR
to the desired
\fIformat\fR
using whatever means necessary\&. This may involve two steps:
.sp
.RS 4
.ie n \{\
\h'-04' 1.\h'+01'\c
.\}
.el \{\
.sp -1
.IP "  1." 4.2
.\}
The application of an appropriate XSL stylesheet using an XSL\-T processor\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04' 2.\h'+01'\c
.\}
.el \{\
.sp -1
.IP "  2." 4.2
.\}
Further processing with other tools\&. This step may not be necessary\&.
.RE
.PP
To decide which stylesheet to use and what, if any, needs to be done to post\-process the output,
\fBxmlto\fR
makes use of
format scripts, which are simple shell scripts that
\fBxmlto\fR
calls during the conversion\&.
.PP
The appropriate format script is selected based on the type of XML file and the desired output format\&.
\fBxmlto\fR
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
\fIformat\fR
on the command line\&.
.PP
Firstly, if
\fBxmlto\fR
has not been told explicitly which stylesheet to use (with the
\fB\-x\fR
option), the format script will be called with
\fB$1\fR
set to
stylesheet\&. The environment variable
\fBXSLT_PROCESSOR\fR
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\&.
.PP
Secondly, after an XSL\-T processor has been run using the stylesheet, the format script will be called again, this time with
\fB$1\fR
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
\fBXSLT_PROCESSED\fR
and whose basename is that of the original XML file with any filename extension replaced with
\&.proc)\&.
\fBINPUT_FILE\fR
is set to the name of the original XML file,
\fBOUTPUT_DIR\fR
is set to the name of the directory that the output (and only the output) must end up in, and
\fBSEARCHPATH\fR
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\&.
.SH "OPTIONS"
.PP
\fB\-v\fR
.RS 4
Be verbose (\fB\-vv\fR
for very verbose)\&.
.RE
.PP
\fB\-x\fR \fIstylesheet\fR
.RS 4
Use
\fIstylesheet\fR
instead of asking the format script to choose one\&.
.RE
.PP
\fB\-m\fR \fIfragment\fR
.RS 4
Use the provided XSL
\fIfragment\fR
to modify the stylesheet\&.
.RE
.PP
\fB\-o\fR \fIdirectory\fR
.RS 4
Put output in the specified
\fIdirectory\fR
instead of the current working directory\&.
.RE
.PP
\fB\-p\fR \fIpostprocessor_opts\fR
.RS 4
Pass
\fIpostprocessor_opts\fR
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
\fB\-p\fR
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\&.
.RE
.PP
\fB\-\-extensions\fR
.RS 4
Turn on stylesheet extensions for the tool chain in use (\fIuse\&.extensions\fR
is turned on)\&. The variables turned on are the ones used by Norman Walsh\*(Aqs DocBook XSL stylesheets\&.
.RE
.PP
\fB\-\-searchpath\fR \fIpath\fR
.RS 4
Add the colon\-separated list of directories in
\fIpath\fR
as fallback directories for including input\&.
.RE
.PP
\fB\-\-skip\-validation\fR
.RS 4
Skip the validation step that is normally performed\&.
.RE
.PP
\fB\-\-stringparam\fR \fIparamname\fR=\fIparamvalue\fR
.RS 4
Pass a named parameter
\fIparamname\fR
with value
\fIparamvalue\fR
to stylesheet from the command line\&.
.RE
.PP
\fB\-\-noclean\fR
.RS 4
Temporary files are not deleted(their names are shown and kept in tmp directory)\&. It could help with analyzing problems\&.
.RE
.PP
\fB\-\-noautosize\fR
.RS 4
By default, some XSL variables are overridden by autodetection (\fIpage\&.width\fR
and
\fIpage\&.height\fR
for
paperconf
(libpaper) use,
\fIpaper\&.type\fR
for locale\-based (\fBLC_PAPER\fR) selection)\&. With this option,
\fBxmlto\fR
doesn\(cqt use this autodetection and user is able to modify defaults himself (either via default
param\&.xsl
modification or by user\-defined XSL fragment)\&.
.RE
.PP
\fB\-\-noextensions\fR
.RS 4
By default,
\fBxmlto\fR
enables XSL params
\fIpassivetex\&.extensions\fR
for
passivetex
backend and
\fIfop\&.extensions\fR
and
\fIfop1\&.extensions\fR
for
fop
backend\&. This usually produces better results\&. If you for some reason don\*(Aqt want to use these parameters, just disable them using this option\&.
.RE
.PP
\fB\-\-profile\fR
.RS 4
Pre\-process the XML document with the profiling stylesheet\&.
.RE
.PP
\fB\-\-with\-fop\fR
.RS 4
Use
fop
for formatting\&. It is an experimental option, expects
fop
in specific location(detected at configured time), could be changed manually in
\fBxmlto\fR
script by modification of
\fIFOP_PATH\fR
.RE
.PP
\fB\-\-with\-dblatex\fR
.RS 4
Use
dblatex
for formatting\&. It is an experimental option, expects
dblatex
in specific location(detected at configured time), could be changed manually in
\fBxmlto\fR
script by modification of
\fIDBLATEX_PATH\fR
.RE
.PP
\fB\-\-help\fR
.RS 4
Display a short usage message\&. It will describe xmlto\*(Aqs options, and the available output formats\&.
.RE
.PP
\fB\-\-version\fR
.RS 4
Display the version number of xmlto\&.
.RE
.SH "ENVIRONMENT"

Directory, where to create temporary stylesheets (default:
/tmp)\&.

xmlto
script are set properly\&.

\fB10+(Validation non\-zero error code)\fR
