Use the Regular Expression (Regex) Tester

You can use the Regular Expression (Regex) Tester to validate a regular expression before using the expression in CA SOI.

Follow these steps:

1. In a dialog that supports regex, click Test Regex.

   The Regex Tester dialog appears.

   The Operation field describes the conditions:

   • The case-sensitivity
   • If the pattern is to match or not match

   If you entered an expression in the Attribute Value field, the expression appears in the Regex Pattern for editing.

2. Enter (or edit) the regular expression in the Regex Pattern field.

   The Valid? field indicates if the expression you entered is a valid regular expression. The field displays Yes or No.

3. Enter a test string in the Test Text field.

   The Found?/Not Found? field indicates if the regular expression finds or does not find the Test Text string, based on the Operation conditions. The field displays True or False.

4. Perform one of the following actions:
   • Click Use Pattern to close the RegEx Tester dialog and transfer the Regex Pattern to the Attribute Value field.
   • Click Cancel to close the RegEx Tester dialog and leave the Attribute Value field unchanged.
