Appendix A: Regular Expressions

This appendix explains how to use regular expressions to specify the GTYPE, and optionally the SCSTYPE, that will be automatically mapped to an ISO15926 component class when using the Auto Complete feature of the GTYPE Mapping dialog. For further information, refer to Set Up Rules for Automatic Completion of ISO 15926 Mappings in 3.4.1 Viewing/Editing ISO 15926 Mappings. (It is not intended as a comprehensive guide to Regular Expressions.)

Regular Expressions are used to identify text containing characters, words, or patterns of characters.

Regular Expressions are written in a formal language that can be interpreted to identify text that matches the provided expression. Regular expression use metacharacters, which are characters which have a special meaning, and literals, which are the string you wish to match.

In this section all example Regular Expressions are shown as syntax. All examples of text that would match a Regular Expression used as an example are shown in Bold.

The following operations are used to construct regular expressions.
