Mapping statement types define XMap mapping logic. Define the mapping statement type based on whether you want to map a simple input value to an output value, iterate over an element, or perform the mapping based on a condition.
Create a statement by dragging an input schema element to an output schema element, or adding a mapping statement to the grid. When you create a statement, the Data Processor transformation identifies a mapping statement type based on whether the element is a simple element, a complex element, or a repeating element.
The basic mapping statement type is a Map, which maps a simple input value to a simple output value. Other mapping statements identify conditions or alternatives for mapping logic, or group a set of logical statements.
You can define the following types of mapping statements in the grid:
Maps a simple input element to a simple output element. A Map statement is the basic building block of the XMap.
A logical group of statements. Other mapping statement types are nested under the Group statement.
A group statement that the Data Processor transformation performs each time the input element appears in the input document. The Repeating Group contains Map statements which are iterated. The Repeating Group identifies the element used to iterate the group.
Contains a group of Option statements, and selects only the Option statement whose condition criteria matches the input. If none of the Options apply, a Default action is taken, if there is a Default statement. If none of the Options apply and there is no Default statement, the Router fails.
One or more Option statements are nested under the Router statement. The Option statement is like a Group statement, and contains a logical group of statements. The Option statement defines a condition to map the input element to the output element.
One Default statement can be nested under the Router statement. The Default statement is performed when none of the Option statements apply. If the all the Option statements fail and there is no Default statement, the Router fails.
Calls another XMap object in the Data Processor transformation.
Calls a mapplet from the Data Processor transformation.
One or more MappletInput statements can be nested under the RunMapplet statement. Values are mapped to the mapplet input ports in the same order that they are listed in the MappletInput statements.
One or more MappletOutput statements can be nested under the RunMapplet statement. The values in the mapplet output ports are mapped to the MappletOutput statement in the same order that they are listed in the mapplet ports.
Mapping statements contain fields that you can configure to customize the statement. You can configure the input, output, and condition for mapping an input element to an output element.
Configure whether to skip a mapping statement when it fails or there is no input. Configure whether the Data Processor transformation adds an output element or matches an existing element with a value from a mapping statement.
