Schema for Flat File - xsd

Question

I have to do to a transformation from flatfile to xml but the problem is that the flatfile has multiple child nodes and the child nodes have sub nodes as well. The records are occuring multiple times in the file. I had created a schema but it processes only single record.
Can you please tell me the structure of the schema I should create that can process mulitple records.
Here is the flat file.

Answer 1

Here is a schema that parses the records correctly which uses both Tag Identifier and Sequence Groups. I have not defined all the fields, but just put a repeating field under each record which you can replace with the proper fields.
