dtdtree - generate a tree view of an SGML Document Type Definition (DTD)

dtdtree [options ] < file

dtdtree is a filter which expects an SGML DTD on STDIN and sends a tree view of an SGML DTD to STDOUT. Unlike dtd2html, the output of dtdtree is plain text, rather than a navigable hypertext document.

dtdtree 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.

This program takes the following command-line options:

-catalog file

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

-dtd file

Parse the DTD named by file. Otherwise, read from STDIN.

-help

Print a brief usage description. No other action is performed.

-level #

Set the prune level of the content hierarchy tree to #. Defaults to 15.

-treefile file

Output element content tree(s) to file rather than STDOUT.

-verbose

Ouput to standard error messages of what dtdtree is doing. This option is mainly for debugging purposes.

dtd2html (1), dtddiff (1), dtdview (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) .
