When you define hierarchical output groups in the Unstructured Data transformation, you must define the same structure in the

Data Transformation

service that you create to transform the data. Export the hierarchy structure as an XML schema file from the Unstructured Data transformation. Import the schema to your Data Processor transformation. You can then map the content of a source document to the XML elements and attributes in the Data Processor transformation.

To export the group hierarchy from the

Relational Hierarchy

tab, click

Export to XML Schema

. Choose a name and a location for the XSD file. Choose a location that you can access when you import the schema with Information Developer.

The Designer creates a schema with the following namespace:

The schema includes the following comment:

If you modify the schema,

Data Transformation

Engine might return data that is not the same format as the output ports in the Unstructured Data transformation.

The XML elements in the schema represent the output ports in the hierarchy. Columns that can contain null values have a minOccurs=0 and maxOccurs=1 XML attribute.
