XML Mask (XmlMaskGenerator)

The XML Mask generator runs a selected generator on values that match a user specified path expression.

Link object structure

For the XML Mask generator, there is a link object for each path expression value to assign a sub-generator to.

The generator does not itself support consistency or differential privacy.

The metadata object is populated from the XmlMaskMetadata object. It includes:

• pathExpression, which is the expression that identifies the value to apply the sub-generator to.

• The subGeneratorMetadata object, which identifies and configures the sub-generator.

  "metadata": {
    "generatorId": "XmlMaskGenerator",
    "customValueProcessor": "string",  //If custom value processor applied
    "pathExpression": "string",
    "subGeneratorMetadata": {
      "presetId": "string",
      "generatorId": "string",
      //Metadata for the selected sub-generator
      "customValueProcessor": "string"  //If custom value processor applied to the sub-generator
    }
  }
}

Example replacement

In the following example replacement for the XML Mask generator:

• The Name generator is assigned to the path expression //view/item-descriptor//@display-name. The value is in the format First Name Last Name (John Smith), and capitalization is not preserved. Consistency is disabled.

• The Constant generator is assigned to the path expression //view//object-class. The constant value is object-class.
