The following table lists additional flat file node properties that do not appear in the Schema Editor. Using these properties requires hand editing the schema file in a text editor.
| Property | Values | Default Value | Description |
|---|
| suppress_empty_nodes | true or false | false | Indicates whether or not to remove empty XML nodes after the parser generates XML instance data. |
| generate_empty_nodes | true or false | true | Generate empty nodes for records that exist in the XML instance data. |
| parser_optimization | speed or complexity | speed | Optimizing for speed decreases the parsing time but at the cost of dealing with some ambiguities in data. Optimizing for complexity handles a wider range of ambiguities but at the cost of processing speed. |
| lookahead_depth | Any positive integer; zero (0) indicates infinite lookahead. | 3 | How far to look ahead for matching data. |
| allow_early_termination | true or false | false | Indicates whether positional records can terminate early (true) or must contain data for all record fields (false). |
All of these properties are attributes of the /annotation/appinfo/schemaInfo element.
When parser_optimization is set to complexity, you may have validation failures against a schema when there are many optional nodes in the same group or record. You may need to set lookahead_depth to zero (0) to avoid validation errors.
