Customize - Regex Library Editor - Modifying Regex Library Files

After using the Regex Library Editor Test Area to test your regular expressions, you might find some unintended effects because of the order of your expressions.

To alter the expression order in a Regex Library:

1. In the Regex Library Editor, select the row you want to move.
2. Drag the row to the desired location, and then release the mouse button. The row appears in its new position.

Tips:

• If your substitution string is empty, the matched pattern is removed because it is replaced with nothing.
• During parse normalization and matching, strings are capitalized before regular expressions are applied. So, you should make regular expressions case-insensitive in libraries that will be used for these purposes. Or, you can use only capital letters when representing literal text in the expressions. During parse pre-processing, strings are not capitalized before regular expressions are applied. Therefore, you can use case-sensitive regular expressions in libraries used for pre-processing if there is some benefit to doing this.
