defining dfdl:terminator and dfdl: initiator using length
Hello! Is it possible to define the initiator and terminator using their length? I know my data will have an initiator and a terminator, but not what they will be, only that they will exist and their length. If it's not possible, what is the best way to accomplish this?

Usually an initiator acts as an identifier for the data. In your case, it sounds as if you simply want to skip over some leading/trailing data. Possible solutions: - define hidden elements of the required lengths. You will need to put each element into a global group and refer to the group via a hiddenGroupRef annotation. That may sound awkward, but it ensures that the parsed infoset can be validated against the xsd. - if the initiators and terminators have a known length in bytes then you could use ( misuse? ) leadingSkip and trailingSkip to ignore them. regards, Tim Kimber, DFDL Team, Hursley, UK Internet: kimbert@uk.ibm.com Tel. 01962-816742 Internal tel. 37246742 From: Miguel Vieira <carlos.vieira@gmv.com> To: "dfdl-wg@ogf.org" <dfdl-wg@ogf.org> Date: 30/08/2012 14:14 Subject: [DFDL-WG] defining dfdl:terminator and dfdl: initiator using length Sent by: dfdl-wg-bounces@ogf.org Hello!
