.SH "NAME"
dtdparse \- Generate an XML representation of an SGML or XML DTD.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\& dtdparse [options] [dtdfile]
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBdtdparse\fR parses an \s-1XML\s0 or \s-1SGML DTD\s0 and prints an \s-1XML\s0 representation
of it.  The \s-1XML\s0 version can be further processed by other tools to
aid in the analysis and documentation of the \s-1DTD.\s0
.PP
The first non-option-related argument provided on the command-line
specifies the file to parse.  If no filename is given, then the
\&\s-1DTD\s0 is read from standard input.
.PP
The generated \s-1XML\s0 document is printed to standard output unless
the \f(CW\*(C`\-\-output\*(C'\fR option is specified.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\-\-catalog <catalog>" 4
.IX Item "--catalog <catalog>"
Specify catalog files to parse for resolving external entity
references.  This option can be specified multiple times.
.Sp
\&\fB\s-1NOTE:\s0\fR Currently, only \s-1SGML\s0 Open Catalog format is supported.
\&\s-1XML\s0 Catalog support is not implemented (yet).
.IP "\-\-debug" 4
.IX Item "--debug"
Extra debugging output.  This option can be specified multiple
times to increase the amount of output.
.Sp
Debugging output is sent to standard error.
.IP "\-\-declaration <file>" 4
.IX Item "--declaration <file>"
Specify the \s-1SGML\s0 declaration.  The \s-1SGML\s0 declaration is parsed
to determine the type of \s-1DTD\s0 being parsed, \s-1XML\s0 or \s-1SGML.\s0  The
key parts of the \s-1SGML\s0 declaration examined are the \s-1NAMECASE\s0
and \s-1CHARSET\s0 directives to determine the \s-1DTD\s0 type.
.Sp
If no \s-1SGML\s0 declaration is available, the \f(CW\*(C`\-\-xml\*(C'\fR,
\&\f(CW\*(C`\-\-namecase\-general\*(C'\fR, and \f(CW\*(C`\-\-namecase\-entity\*(C'\fR options can
be used.
.IP "\-\-namecase\-general" 4
.IX Item "--namecase-general"
.PD 0
.IP "\-\-nonamecase\-general" 4
.IX Item "--nonamecase-general"
.PD
In the absence of an \s-1SGML\s0 declaration, these options specifiy
if \f(CW\*(C`NAMECASE GENERAL\*(C'\fR is \s-1YES\s0 or \s-1NO.\s0  The default is \s-1YES\s0 unless
\&\f(CW\*(C`\-\-xml\*(C'\fR is specified.
.IP "\-\-namecase\-entity" 4
.IX Item "--namecase-entity"
.PD 0
.IP "\-\-nonamecase\-entity" 4
.IX Item "--nonamecase-entity"
.PD
In the absence of an \s-1SGML\s0 declaration, these options specifiy
if \f(CW\*(C`NAMECASE ENTITY\*(C'\fR is \s-1YES\s0 or \s-1NO.\s0  The default is \s-1NO.\s0
.IP "\-\-output <file>" 4
.IX Item "--output <file>"
Specifies the filename to send \s-1XML\s0 output.
.IP "\-\-public\-id <pubid>" 4
.IX Item "--public-id <pubid>"
The \s-1DTD\s0's public \s-1ID.\s0
.IP "\-\-system\-id <sysid>" 4
.IX Item "--system-id <sysid>"
The \s-1DTD\s0's system \s-1ID.\s0
.IP "\-\-title <title>" 4
.IX Item "--title <title>"
Set the title of the \s-1DTD.\s0
.IP "\-\-unexpanded" 4
.IX Item "--unexpanded"
.PD 0
.IP "\-\-nounexpanded" 4
.IX Item "--nounexpanded"
.PD
Include, or do not include, unexpanded content models in generated \s-1XML.\s0
By default, unexpanded content models are included.
.Sp
It is common for \s-1DTD\s0 authors and maintainers to use parameter entities
within content models.  When this option is enabled, dtdparse will
include a version of content models with parameter entities not
expanded.
.IP "\-\-verbose" 4
.IX Item "--verbose"
.PD 0
.IP "\-\-noverbose" 4
.IX Item "--noverbose"
.PD
Print parsing progress.  By default, this option is enabled.
Verbose output is sent to standard error.
.Sp
If \f(CW\*(C`\-\-debug\*(C'\fR is specified, then this option is automatically
enabled.
.IP "\-\-xml" 4
.IX Item "--xml"
.PD 0
.IP "\-\-noxml" 4
.IX Item "--noxml"
.PD
In the absence of an \s-1SGML\s0 declaration, this option specifies if
the \s-1DTD\s0 is an \s-1XML DTD\s0 or an \s-1SGML DTD\s0 (the default is \-\-noxml).
.IP "\-\-version" 4
.IX Item "--version"
Print version and synopsis.
.IP "\-\-help" 4
.IX Item "--help"
Print synopsis and options available.
.IP "\-\-man" 4
.IX Item "--man"
Print manual page.
