Usage

Overview

dtdparse parses an XML or SGML DTD and prints an XML representation of it. The XML version can be further processed by other tools to aid in the analysis and documentation of the DTD.

The first non-option-related argument provided on the command-line specifies the file to parse. If no filename is given, then the DTD is read from standard input.

The generated XML document is printed to standard output unless the "--output" option is specified.

Options

--catalog <catalog>

Specify catalog files to parse for resolving external entity references. This option can be specified multiple times.

NOTE: Currently, only SGML Open Catalog format is supported. XML Catalog support is not implemented (yet).

--debug

Extra debugging output. This option can be specified multiple times to increase the amount of output.

Debugging output is sent to standard error.

--declaration <file>

Specify the SGML declaration. The SGML declaration is parsed to determine the type of DTD being parsed, XML or SGML. The key parts of the SGML declaration examined are the NAMECASE and CHARSET directives to determine the DTD type.

If no SGML declaration is available, the "--xml", "--namecase-general", and "--namecase-entity" options can be used.

--namecase-general

--nonamecase-general

In the absence of an SGML declaration, these options specifiy if "NAMECASE GENERAL" is YES or NO. The default is YES unless "--xml" is specified.

--namecase-entity

--nonamecase-entity

In the absence of an SGML declaration, these options specifiy if "NAMECASE ENTITY" is YES or NO. The default is NO.

--output <file>

Specifies the filename to send XML output.

--public-id <pubid>

The DTD's public ID.

--system-id <sysid>

The DTD's system ID.

--title <title>

Set the title of the DTD.

--unexpanded

--nounexpanded

Include, or do not include, unexpanded content models in generated XML. By default, unexpanded content models are included.

It is common for DTD 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.

--verbose

--noverbose

Print parsing progress. By default, this option is enabled. Verbose output is sent to standard error.

If "--debug" is specified, then this option is automatically enabled.

--xml

--noxml

In the absence of an SGML declaration, this option specifies if the DTD is an XML DTD or an SGML DTD (the default is --noxml).

--version

Print version and synopsis.

--help

Print synopsis and options available.

--man

Print manual page.
