# dtdview(1)

interactively study an SGML Document Type Definition (DTD)

## NAME

dtdview — interactively study an SGML Document Type Definition (DTD)

## SYNOPSIS

**dtdview** \[options \]  \[*file*\]  \[ \< *commands*\]

## DESCRIPTION

**dtdview** is an interactive querying tool to examine  the contents on an SGML Document Type Definition (DTD).  The DTD  may be specifed by *file*, or as the argument  of one of the commands understood by dtdview.

**dtdview** can alternatively be used in batch mode.    It will take commands from STDIN.  Full details  are  provided  in  the online documentation; see below.

**dtdview** is one of a  suite  of  tools available   in  the perlSGML  package, which together help one inspect, study,  and edit if necessary, an SGML Document  Type  Definitions  (DTD).    The   package   was   written   by   Earl   Hood  (ehood@medusa.acs.uci.edu).

This manual page was written for the **Debian GNU/Linux** distribution  because the original program does not have a manual page.  Instead, it has documentation in the **HTML**       format; see below.

## OPTIONS

This program takes the following command-line options:

- **-catalog** *file*

  Use *file* to map public   identifiers and external entities to system files.

- **-help**

  Show summary of options.

- **-verbose**

  Print parsing information if a DTD is specified on   the command-line.

## COMMANDS

**dtdview** takes any one of two dozen commands.   A few of these are:

**help** \[*element*\]   With no argument, this command lists all the other commands.  With an argument, it provides a usage statement and a short  description of the action of the named *command*.

**content** \[*element*\]   With no argument, list the content of the command currently  at the top of element hierarchy.  Otherwise,   list the content of the named *element*.

**tree** \[*element*  \[*depth*\] \]   Print content tree of *element* with  a depth of *depth*.  The default depth  is 2.

## SEE ALSO

dtd2html (1), dtddiff (1), dtdtree (1), and stripsgml (1).  These commands, as well as perlSGML's library of Perl modules   for parsing of the SGML DTD's are documented fully by       *The perlSGML Manual (link to URL http://www.oac.uci.edu/indiv/ehood/perlSGML/doc/html/perlSGML.html)* .
