Converting a flat file to nested xml structure in FCC

Hi All,

I am required to convert the below flat file structure into nested xml structure as below. Do I need and intermediate structure or FCC parameters in the File adapter is enough to convert it?

Flat File Structure: Has a File Header (5 fields), Document Header (10 fields), Items with respect to the Document Header (12 fields)and Footer of 3 fields

Sample Source Flat File Structure:

HEADER,ABC GL DAILY,20150208,0108251.0

H,YYYYMMDD,YYYYMMDD,A1,1100,USD,,,P-YYYYMMDD-1,SDRECONYYYYMMDD,

I,10,1234567,10241420.25,10241420.25,,,12345,ACC K,ACC P,ACC20130527,RECONKEY

I,20,1234567,10241420.25,10241420.25,,,12345,ACC K,ACC P,ACC20130527,RECONKEY
