This is a simple sample Document Type Definition (MyFIX.dtd):
This is a simple sample XML which shall use the above DTD

Now you want a Cobol copybook (MYFIX.COBOL) like
1. FIX_MESSAGE.
10. FIX_HEADER.
20. FIX_VERSION PIC X(10).
88 VERSION_FIX40 VALUE 'FIX.4.0'
88 VERSION_TIF VALUE 'FIXT.5.0'
20. BODY_LENGTH PIC N(6).
20. FIX_MESG_TYPE PIC XXX.
88 MESG_TYPE_LOGON VALUE 'A'.
10. FIX_MESG_BODY.
20 TICKER_SYMBOL PIC X(20).
10 FIX_MESG_TRAILER.
20 FIX_CHECKSUM PIX NNN.
which you want to use like COPY MYFIX. What language are you planning to use to develop this converter? I know how to do it using Java-XML tools. You would also need a bidirectional FIX-TCP to COBOL adapter which would convert FIXML message to COBOL record and call a Cobol program passing the Cobol record which it constructed using the values in the FIXML and convert from Cobol program output to FIXML record and "run" the FIX session - ie. send it to counterparty.
Regarding "2. Convert FIXML DTD to standard xml message structure.", I did not get it, I would use a DTD to validate a message, I would have a Java program convert my Cobol data into a FIXML / XML message and check it using the DTD before sending it on the wire.
Correct me if my assumptions about your EAI project are incorrect.
