Note: the development of this tool has moved to NCBITools/DtdAnalyzer. Please update your bookmarks.


This tool will create an XML representation (using elements and attributes) of an XML DTD.


dtdanalyzer [options] [<output file>]

All options have a short and a long form. At least one option must be given that specifies the DTD that is to be processed:

  • -s, --system system-id - Use the given system identifier to find the DTD. This could be a relative pathname, if the DTD exists in a file on your system, or an HTTP URL.
  • -d, --doc xml-file - Specify an XML file used to find the DTD. This could be just a "stub" file, that contains nothing other than the doctype declaration and a root element. This file doesn't need to be valid according to the DTD.
  • -p, --public public-id - Use the given public identifier to find the DTD. This would be used in conjunction with an OASIS catalog file.

Other possible options and arguments are:

  • -h,--help - Print usage information and exit.
  • -c, --catalog catalog-file - Specify a file to use as the OASIS catalog, to resolve public identifiers
  • -x, --xslt xslt-file - An XSLT script to run to post-process the output. This is optional.
  • -t, --title dtd-title - Specify the title of this DTD. This will be output within a <title> element under the root <declarations> element of the output XML.
  • <output file> - Name of the file to write the output to. If this argument is not given, the output is written to standard out.


Process the NISO JATS Journal Archiving and Interchange DTD, and write the output to a file:

dtdanalyzer --system \

Development environment / getting started

The development environment for this project is very rudimentary at present, and uses make. To use the scripts that come with the package, first set the environment variable $DTDANALYZER_HOME to the root of the git repository. For example (Unix):

git clone git://
cd DtdAnalyzer
export DTDANALZER_HOME=`pwd`

Next, set up your environment using either the or setenv.bat scripts in the scripts directory. On Unix,

. script/

On Windows,


Next, you'll want to download all the dependencies into the lib directory. This script is only available for Unix. On Windows, you'll have to do it manually.

See below for a list of the dependencies.

To build the project, use make. The Makefile targets are:

  • all - default target, everything below.
  • clean - deletes intermediate files
  • bin - compiles all .java → .class; results go into 'class' directory
  • doc - builds javadocs; puts results into 'doc'
  • t - runs the script over the test file in the 'test' directory

To run, from the test directory, for example,

dtdanalyzer --doc archiving-3.0.xml out.xml


The following jar files are required. You can use the script to download and unpack these, if you like (Unix only).
