You can configure a step to apply a regular expression to the values in an input field. The step writes any value that matches the expression logic to one or more output fields.
1On the Configuration tab, select the option to add a step to the asset.
The Add Step dialog box opens onscreen.
2Select Regular Expression as the step type.
3Select the Built-in or Custom option.
- To select a regular expression from a list of built-in expressions, select Built-in.
- To enter a regular expression that the step will use, select Custom.
Select or enter a regular expression that describes the character composition of the values that you want the step to find at run time.
4In the Outputs field, enter the name of the field to which the step will write any input value that matches the regular expression logic. The step creates the field at run time.
Press the Enter key after you enter each field name.
You can create more than one output. Create additional outputs if the step might find more than one value that matches the expression logic within a single input field.
A built-in regular expression might require more than one output. When you select the Built-in option, the Number of Outputs field displays the number of outputs to create.
