How to configure

Adding a regular expression

To add a regular expression:

1. Click Add Regex. On the configuration panel, Cell Value shows a sample value from the source database. You can use the previous and next options to navigate through the values.

2. By default, Replace all matches is enabled. To only match the first occurrence of a pattern, toggle Replace all matches to the off position.

3. In the Pattern field, enter a regular expression. If the expression is valid, then Structural displays the capture groups for the expression.

4. For each capture group, to select and configure the generator to apply, click the selected generator. You cannot select another composite generator.

5. To save the configuration and immediately add a generator for another path expression, click Save and Add Another. To save the configuration and close the add generator panel, click Save.
