PROGRAM:

NAME

dtddiff - Compare two SGML/XML DTDs

SYNOPSIS

dtddiff [options] <parsed-dtd1.xml> <parsed-dtd2.xml>

DESCRIPTION

dtddiff compares two SGML/XML DTDs based upon the XML dumps generated by dtdparse. The
following summarizes the typically usage of dtddiff:

dtdparse --outfile parsed-dtd1.xml dtd1.dtd
dtdparse --outfile parsed-dtd2.xml dtd2.dtd
dtddiff parsed-dtd1.xml parsed-dtd2.xml > dtd.diff

Since dtddiff processes the XML dumps from dtdparse, a full reparse of the DTDs is
avoided.

dtddiff does a structural-based comparision. Therefore, the order of declarations in the
DTDs does not affect the comparison.

The output generated by dtddiff is similiar in style to a context-based diff done by the
program diff(1). The following is an example of the type of output generated:

starting with a "+ " (plus followed by a space) denote items added. Lines starting with a
"! " (explanation point followed by a space) denote items changed.

OPTIONS

--attributes
--noattributes
Print, or not, element attribute differences. The default is to print differences.

--content-model-expanded
--nocontent-model-expanded
Expand, or not expand, element content models during comparison. Expanded models have
all parameter entities resolved. The default is to use expanded content model.

--elements
--noelements
Print, or not, element content model differences. The default is to print
differences.

--general-ents
--nogeneral-ents
Print, or not, general entity differences. The default is to not print differences.

--parameter-ents
--noparameter-ents
Print, or not, parameter entity differences. The default is to not print differences.

--dump
Do a textual dump of a DTD. When this option is specified, only a single DTD is
dumped. This is mainly used for debugging purposes.

--version
Print version and synopsis.

--help
Print synopsis and options available.

--man
Print manual page.
