Regular expression options

When you add a step to a labeler asset, Data Quality prompts you to define a step with a regular expression or with a dictionary.
The following image shows the options that you configure when you define a step with a regular expression:
The image shows the Configuration tab of a labeler asset for Token labeling. The tab displays a sequence of a labeler step, the regular expression properties of the step, the test panel, and the run-time environment options.
The regular expression options include the following properties:
  1. 1Labeler mode.
    2. Indicates the type of labeling operations to perform on the input data.
  2. 2Add Step option.
    3. Adds a step to the asset. A step describes a labeling operation that a mapping can apply to an input data field.
  3. 3Up and Down options.
    4. Moves a step that you select up or down within the step sequence.
  4. 4Step sequence.
    5. Defines the order in which a mapping applies each step to the input field at run time. The mapping performs labeling operations in the order that you specify.
  5. 5Options name.
    6. Identifies the type of regular expression in the step.
  6. 6Test input field.
    7. Contains the input data that the Secure Agent uses to test the steps in the labeler sequence.
  7. 7Test output fields.
    8. Contain the result of the test.
    The test output fields contain the following data:
  8. 8Import file option.
    9. Imports data to the test panel.
  9. 9Step type.
    10. Identifies the type of step to which the properties apply.
  10. 10Regular expression type.
    11. Specifies whether the step uses a built-in regular expression or a regular expression that you define.
    A built-in regular expression is one that you select from a list that the asset provides. A custom regular expression is one that you define.
  11. 11Regular Expression.
    12. In Custom mode, the field contains the regular expression that you specify. You enter the regular expression logic in the field.
    In Built-in mode, the Regular Expression Name field displays the name of the regular expression that you select. Additional fields display the regular expression logic and a description of the regular expression.
  12. 12Label name.
    13. Specifies the label that the step applies to the values in an input string.
    You provide the label for a custom regular expression. A built-in regular expression has a default label. You can accept the default label or specify a label you prefer.
