When you use the Hierarchy Parser transformation, consider the following rules and guidelines.
Source file size
The Hierarchy Parser transformation can process source files that are up to 1.5 GB in size. To process files that are larger than 1.5 GB, use an intelligent structure model. For more information about intelligent structure models, see Components.
Handling of Boolean data types
The Hierarchy Parser transformation always returns 0 for Boolean data type input.
Hierarchical schema that is based on an XSD file
When you associate a hierarchical schema that is based on an XSD file with a Hierarchy Parser transformation, note that you can't use the Hierarchy Parser transformation with the following XSD component types:
•xsd:any
•xsd:type
•mixed
•xsi:type
•default values
•fixed values
•no type, for example <xs:element name="A" maxOccurs="unbounded"/>
To parse large or complex XSD files that contains more than 10,000 elements and attributes, recursive elements, or complex deep hierarchies, use the Structure Parser transformation. For more information, see Structure Parser transformation.
Using a Hierarchy Parser transformation in a Mapplet transformation
When you use a Hierarchy Parser transformation in a mapplet, to prevent runtime errors, be sure that the combined Mapplet transformation name doesn't exceed 80 characters. For more information, see Mapplet transformation names.
