Subject:        [DFDL-WG] Specify field based on the beggining of the binary file
Sent by:        dfdl-wg-bounces@ogf.org




Hi!
 
I have a binary file specification that specifies some fields referenced by the beginning of the binary info.
For instance imagine that there is a field with 1024Bytes and the next one starts at byte 512 counting from the beginning of the info.
 
Is it possible to do that using dfdl?
I’ve seen dfdl:floating, but I can’t find much info on that.
 
Thanks.
