Choice Element

Choice Element

A choice element restricts a child element to one of the elements in the <choice> declaration.
The following text shows a person element that is an employee or a contractor:
<xs:element name="person"> <xs:complexType> <xs:choice> <xs:element name="employee" type="employee"/> <xs:element name="contractor" type="contractor"/> </xs:choice> </xs:complexType> </xs:element>
You can map choice elements using the following methods:
  • Create output ports for each choice element in an output group. Some elements will have null values in the output row.
  • Create an output group for each choice. For the above example, create an employee group and a contractor group. The Data Integration Service generates a row based on which element appears in the SOAP message.
