Choice Element

A choice element restricts a child element to one of the elements in the <choice> declaration.

To map ports to a SOAP message that contains choice elements, create one input group that includes all the elements in the choice construct. For example, an item description might be a dimension or a weight:

item: description, choice {dimension, weight}

When the description is a dimension, the description is a complex type that contains, length, width, and height.

When the description is a weight, the description is a simple string type.

The input data has the following columns and rows:

description	length	width	height	weight
box	20cm	18cm	15cm	NULL
coffee	NULL	NULL	NULL	500g

The SOAP message contains an Item group that contains dimensions or weight descriptions:

Item
   Description
       Dimension
          Length 
          Width
          Height
       Weight

The NULL values in the input data become missing elements in the XML output.

The SOAP message contains the following data:

<item>
   <desc>box</desc>
      <dimension>
        <length>20cm</length>
        <width>18cm</width>
        <height>15cm</height>
      </dimension>
</item>

<item>
   <desc>coffee</desc>
      <weight>500g</weight>
</item>
