For the fixed length data i want to achieve a grouping as below..Can anybdy confirm that whether this kind of grouping is

possible in DFDL

Sample Data : HeaderARecordBRecordARecordARecordBRecordTrailer

Header,trailer and Records are fixed length (5000 characters)
ARecord initiator = A
BRecord initiator = B

Code:

Header
Records
ARecords
A
A
A
BRecords
B
B
Trailer

And i also wanted to know whether is it possible to include Initiator in the extracted data....when we specify a initiator DFDL skips the initiator and extracts the data...since initiator is part of my data is it possible to include it.

Help much appreciated

Thanks

kimbert

Sometimes, DFDL can produce the exact tree structure that you need.
Sometimes that is not possible, and you need to put in some simple transformation logic.

In this case, you cannot produce the tree structure that you really want because DFDL does not allow a sequence group or a choice group to have maxOccurs > 1. I recommend that you produce a DFDL model that parses the data correctly, and then write some ESQL/Java or design a map that changes the tree structure.
