Union Element

The union element is a simple type that is a union of more than one type. When a SOAP message contains a union element, you must map a single input port that contains the data in a string.

For example, the SOAP message contains an element called size. Size is a union of integer and string:

<xs:element name="size">
  <xs:simpleType>
    <xs:union memberTypes="size_no size_string" />
  </xs:simpleType>
</xs:element>

The input rows contain items with a description and size. An item can have a numeric size, such as 42. Or, an item can have a size that is a string value, such as large, medium, or small.

The following table shows input rows with a numeric size and a string size:

Desc	Size
shoes	42
shirt	large

Create one port for the item size. Map the port as a string. The SOAP message contains the following elements:

<item>
   <desc>shoes</desc>
   <size>42</size>
</item>

<item>
   <desc>shirt</desc>
   <size>large</size>
</item>
