Version 20020430

The main component of this distribution is code for translating from the regular expression syntax of XML Schema Part 2 into the syntax of regular expressions used by the JDK 1.4 java.util.regex package. Although these two syntaxes are superficially similar, there are numerous differences, many of them rather subtle.

• xsdregex.jar contains the compiled code
• the src directory contains the source code
• there is also API documentation

There is also some supporting code:

• a simple API for matching regular expressions
• implementations of this interface using
  • the Xerces 1 regular expression implementation
  • the Xerces 2 regular expression implementation
  • translation into JDK 1.4 java.util.regex regular expressions
• testing framework using this interface (in the package com.thaiopensource.datatype.xsd.regex.test and in the test directory)
• code for dynamically loading the appropriate implementation using the service provider approach

To compile from source, you will need:

• JDK 1.4 (i.e. J2SE 1.4 SDK)
• UnicodeData-3.1.0.txt one of the files in the Unicode character database
• if you want support for Xerces 1-based regular expression implementation, Xerces Java 1
• if you want support for Xerces 2-based regular expression implementation, Xerces Java 2
• Ant

Compile by applying Ant to the included build.xml file.
