How to read a record type file in OIC?

Summary:

We are trying to read a file which is a fixed length file, but file has multiple record types. For e.g., file contains a header and multiple detail lines with different formats for an employee. Names details are one row, addresses are on other row, assignment details are again on another row etc.

Is it possible to read such files by defining XSD schema on OIC? Please let us know your thoughts.
