NAME

       trang - convert between different schema languages for XML

SYNOPSIS

       trang  [-I rng|rnc|dtd|xml] [-O rng|rnc|dtd|xsd] [-i input-param] [-o output-param] input-
       file ...  output-file

DESCRIPTION

       trang takes as input a schema written in any of the following formats:

              RELAX NG (XML syntax)

              RELAX NG (compact syntax)

              XML 1.0 DTD

       and produces as output a schema written in any of the following formats:

              RELAX NG (XML syntax)

              RELAX NG (compact syntax)

              XML 1.0 DTD

              W3C XML Schema

       Trang can also infer a schema from one or more example XML documents.

       Trang uses an internal representation based on RELAX NG.  For each supported input format,
       there  is  an  input module that converts a schema in that input format into this internal
       representation.  For each supported output format, there is an output module that converts
       the  internal  representation  into  a  schema in that output format.  Thus, any supported
       input format can be translated to any supported output format.

       Trang requires two command-line arguments: the first is the URI or filename of the  schema
       to be translated; the second is the output filename.

       Trang  infers  the  input  and  output  modules to be used from the extension of input and
       output filenames as follows:

       .rng   RELAX NG (XML syntax)

       .rnc   RELAX NG (compact syntax)

       .dtd   XML 1.0 DTD

       .xsd   W3C XML Schema

       .xml   XML documents (used as examples from which to infer a schema)

       This inference can be overridden using the -I and -O options.

       When the input is XML documents used as examples to infer a schema, more  than  one  input
       file  may  be specified as arguments.  All the input files are specified before the output
       file.

OPTIONS

       -I rng|rnc|dtd|xml
              Specifies which input module to use.

       -O rng|rnc|dtd|xsd
              Specifies which output module to use.

       -i input-param

       -o output-param
              Specifies a parameter for an input (-i) or output  (-o)  module.   The  -i  and  -o
              options  may be used multiple times in order to specify multiple parameters.  There
              are two kinds of parameter: boolean parameters  and  string-valued  parameters.   A
              string-valued  parameter  is  specified  using  the  form  name=value.   A  boolean
              parameter is specified using the form name or no-name.  The  applicable  parameters
              depend  on  the  particular  input  and  output  module.  For details, see the HTML
              documentation.
