Hi All,
Can't get my head around a requirement I have. I have to parse a message which comes in chunks of same length of groups of data having "unique tag" preceding it. The problem is these groups of data are optional and if so, then I have to populate the exact length of spaces in between preceding and the succeeding group of data. Please note that each group of data has a "unique tag".
I do not have any experience with TDS format and am really struggling with it to understand and apply. Is there any way I could parse it in a TDS format and remove the tag as well from the output message?
The Message would look like :
[/b]ABCD<DATA>PQRS<DATA>

You should be using DFDL.
You can remove tags when you map from one format to another...
You can tell DFDL to use spaces if the field is null. This might be a bit difficult for numeric values. If you don't need to break out the individual fields inside the DATA, then you can just treat it as a single string.
You should consider your model to be a repeating sequence of a choice. Each member of the choice is be indicated by one of your tags.

I agree; this is a no-contest. DFDL provides a full list of what it did and why. MRM TDS does not.

That leaves a few questions unanswered. You need to supply some examples, (within in [c o d e] tags, please).

Parsing is something that is done to the input bitstream. But you are now asking about the output message. Do you need to parse this format, or write it? Or both? |

The Tags here are:
1. 00ABC
2. 00DEF
3. 00GHI
4. 01JKLMN
5. 11POIUY
6. 41HYUJI
7. 05YYYCT
Actually I'm trying to convert the old Neon formats into now supported MRM or DFDL parsers.
And yes, after parsing, I need to transform it into an xml. |

So
| Code: |
<message><sequence><sequence repeats until end of file>
<choice>
<record tag=00ABC> <record fields> </record>
<record tag=00DEF> <record fields> </record>
....
..
</choice>
</sequence>
</sequence>
</message> |
Or something similar.

Thanks mqjeff and timber, I have installed IIB v10 developer edition and created a DFDL schema for the message structure. I have created a few complex types and then added them to the main message in a sequential order. The DFDL parse test is successful  , but when I try the flow exerciser and when I deploy the application and try to pass a message, it goes to the backout failure queue.
I have used a compute node which turns the Flat file into an XML and the following error is being shown. Any suggestions?
| Code: |
( <Integration_node>.<Integration server> ) The element with name ''QQQ_LineItem'' and field type ''folderType'' is not valid as the child of Root.XML or Root.XMLNSC.
Each child of Root.XMLNSC must represent a valid XML construct for the top level of an XML document. The only field types that are valid in this position are XMLNSC.Comment or XMLNSC.ProcessingInstruction.
Ensure that the message tree is structured correctly, and that each syntax element has a valid field type. |
Please Note: "QQQ_LineItem" - this complex type contains a few more complex types within itself.[/quote] |

The error suggests that you trying to do something like
| Code: |
Root.XMLNSC.tag1
Root.XMLNSC.tag2
Root.XMLNSC.tag3 |
This would result in an invalid XML because it is missing it's XML root tag
You need something like
| Code: |
Root.XMLNSC.xmlroottag.tag1
Root.XMLNSC.xmlroottag.tag2
Root.XMLNSC.xmlroottag.tag3 |
Hope it helps

Thanks fjb_saper, Fixed it with just adding a root tag in the "OutputRoot.XMLNSC.---". |
