Hello All,
I am trying to develope a DFDL for unordered data like
HDRGEO31 CTRL COBMIN
101000000068725095
201000000068725095000000067977231000000000000001
301000000068725095000000222693640000000000000001C
3010000000
301000000068725095000000222693640000000000000001C
401000000068725095000000161647068000000000000001
428000000068725095000000222693641000000000000002
30200000006872509500000003471005800000000000000
4010000000687250950000001616470710000000000
4280000000687250950000002226936420000000000000
428000000068725095000000222693642000000000000003
30200000006872509500000003471005800000000000000
4010000000687250950000001616470720000000
From my understanding i need to set the property SequenceKind = Unordered.
but for sequenceKind there is only ordered option.
could any one guide me to figure it out. I am usin IIB v9.
Thanks in Advance.  |

Who says this is un-ordered?
| Code: |
group occurs n
3
4 (occurs 0 to n)
group |

| Why can't you use DFDL initiators to identify records and put them in a choice that repeats? |

Hello mqjeff,
401000000068725095000000161647068000000000000001
428000000068725095000000222693641000000000000002
30200000006872509500000003471005800000000000000
4010000000687250950000001616470710000000000
401 came again after 302 so i thought it is un-ordered.
I developed a DFDL with sequence groups and i am getting a parser error after 302
could any one advice me on this
From my understanding i am getting this error because 401 is came again and to figure it out i have set occurrence count kind to expression and have to set a value to occurs count, if so i am novice in setting occurs count.
Thanks in advance. |

Actually if your occurrences are truly random, this is the best advice.

If you have a set of records that will appear in a known order, then create a sequence that has those records appear in that order.
If that set of records can repeat in the document, then put that sequence in a container that lets it repeat.
So if you have a message like
10x
11x
20x
30x
40x
40x
41x
30x
41x
Then you need to create a structure something like
| Code: |
message
header 01 record
11 record
body 20 record
repeating 30 record
repeating, optional 40 record
repeating, optional 41 record |
You will then use the 01,02,etc as initiators to identify the records in the message, to allow the DFDL parser to know when one repeat has ended and the next has started. |

So now you have an entirely different question.
About padding.
DFDL gives you many controls over how each individual field is rendered when it is serialized, including how and when and if whitespace is used to pad fields. |
