I'm working on a gizmo for making it easier to load data into the local data
store (e.g., desktop) when doing tests. The file format is xml; a sample
follows. I'm using Apache Xerces and SAX; this is my first adventure with
parsing an xml file.
Basically, the structure of the xml is that the top level is a dataset, and in
that you can have 0 or more entity-lists and 0 or more entities. Within an
entity-list you can have 1 or more entities; the entity-list specifies the type
of the enclosed entities. Within an entity you can have entity-lists and
entities. Entities can have properties, of the types supported by the data
store (hmm, I just realized that I need to support user defined types as well).
Any nesting of entities or entity-lists within entities means that there is
parenting. In the example below the two entities in the type1 entity-list are
at the top/root level; the entity-list there is a convenience.
I'm posting this to get feedback, suggestions, etc.
Thanks
