Did you know that you can actually suppress empty nodes for inbound flat files. If you have empty fields in a flat file and you don’t want them to end up as empty nodes in your XML instances generated from that, you can specify the attribute suppress_empty_nodes=”true” as part of the b:schemaInfo element in the flat file schema.
For generating empty elements in flat files if their XML counterpart nodes are not available in the instance, specify the attribute generate_empty_nodes=”true” as part of the b:schemaInfo element in the flat file schema.
