Creating Conditional Mappings

The if and choose statements are two ways to create conditions. If statements allow you to specify a single condition. Choose/when/otherwise statements allow you to specify multiple conditions, similar to if/then/else.

1. Drag a source to a target to create a mapping.
2. Click the target node to launch the Mapping Builder.
3. Click Mapping Components.
   You can either find or browse for the function.

   • To find the function, type if or choose in the Find field, and click Find.

   • To browse for the function, expand the XSL Elements folder and locate if or choose.

4. Drag the if or choose function onto the target tag statement.
   The statement appears as a parent of the target tag. A new empty row is created with the text Drag and Drop or Type here....
5. Click Source. Then do one of the following:
   • Drag a source element onto the empty row to use a source element as the basis for the test condition.
   • Select an XPath function as the basis for the test condition.
   • Use a literal as the basis for the test condition by typing in the empty row.
6. For choose, you may specify additional when and otherwise conditions.
   1. Right-click the choose statement and select Insert Child.
      A new empty row is displayed with the text Drag and Drop or Type here…
   2. Drag and drop when or otherwise from the Mapping Components list.
7. Click Save.
