In addition to the parsers already provided with the installation of IBM TDI, we can write our own parsers and add them to the system.
One example of a user-defined parser, capable of parsing Regular Expressions, is provided in the Examples directory. Go to the root_directory/examples/regexp_parser directory of the IBM TDI installation. This particular example was written in Java™.
Another example of a user-defined parser can be found in root_directory/examples/script_parser, which shows how to write a parser using scripting. See "JavaScript™ Parser" in the IBM TDI V7.1 Users Guide for a further explanation of this example.
