#DtdAnalyzer

DtdAnalyzer provides a set of tools:

• dtdanalyzer - creates an XML representation (using elements and attributes) of an XML DTD
• dtddocumentor - generates pretty HTML documentation, including annotations (if present) from specially-formatted comments of the DTD
• dtdflatten - flattens a multi-file DTD into one big file. See also the Perl script script/dtdflatten.pl.
• dtdcompare - compares two DTDs and generate a report of differences
• dtd2xml2json - generates XSLT to convert instance documents into JSON format.
• dtdschematron - generates a schematron file from the DTD, including extra schematron rules (if present) from specially-formatted comments of the DTD
• scaffold.xsl - generates XSLT scaffolding that can be used as a starting point for writing a transform from one schema to another

Home page and documentation

The home page for this project is at http://dtd.nlm.nih.gov/ncbi/dtdanalyzer.

Detailed documentation is available on the GitHub wiki.

Quick start

• Download the latest release, either as a zip file: DtdAnalyzer-0.5.zip; or as a gzipped tar: DtdAnalyzer-0.5.tar.gz.

  Note: Do not use the "Zip" download button on the main GitHub page! That button downloads the source files, not the pre-built packages. They are different!

• Unzip that file on your machine.

• Open up a Windows command or a bash shell window. Add the path to the package root to your PATH environment variable.

  On Windows:

  set PATH=%PATH%;-path-to-dtdanalyzer-package-

  On Mac OS X or Unix:

  export PATH=$PATH:-path-to-dtdanalyzer-package-

• Note for Mac OS X: This software depends on a utility called greadlink, which might not be installed on your system. To see whether or not it is, enter which greadlink at a terminal prompt. If it is not installed, then the easiest way to get it is with Homebrew. Install Homebrew, if necessary, and then enter brew install coreutils.

• Try the following command (which analyzes the Journal Archiving and Interchange flavor of the NLM/NISO Journal Article Tag Suite, and writes the output to a file):

  dtdanalyzer http://jats.nlm.nih.gov/archiving/1.0/JATS-archivearticle1.dtd out.daz.xml

• Check that you have sensible results in the output file, out.daz.xml.

• As another example, the next command produces HTML documentation for that DTD. It should run for a little while and then announce that it's done, and that the documentation is in the doc subdirectory. (Enter all on one line).

  dtddocumentor http://jats.nlm.nih.gov/archiving/1.0/JATS-archivearticle1.dtd
  --exclude mml: --exclude-except mml:math

• Open the doc/index.html file in a browser, and check that it looks good.

• Run --help with any of the tools for more complete usage information, or continue by visiting the documentation pages on the GitHub wiki.
