Hello
1. i'm trying to parse message using MRM parser (TDS Format).
2. message built from different kind of lines without any delimiter between the lines.
3. for example one line looks like this :
099@1@123456789@123456789123456789
4. other lines looks like this :
017@k@1234@56789@012345@678901@234567890@12345678912345
5. lines repeats many times , in any order , for example :
AAABBABAB or BABABABABAB , ext.
6. First 3 leters values are different for any kind of line.
Any suggestion for building best parser for this problem ?
Thanks

Yes, TDS is the right parser to use.
Use the first three characters as the tag.
You probably need three groups:
1) choice between types (A, B, etc)
2) repeating structure
3) message that holds repeating structure

Just to back up what Jeff said...
- TDS is the correct physical format to use
- Your message model needs to look something like this:
| Code: |
Element 'Message' type=CTMessage
Complex Type 'CTMessage' Composition='Choice' maxOccurs=-1 Data Element Separation='Tagged Delimited' Delimiter=<CR> Group Terminator=<CR> Tag Data Separator='@'
Local Element 'el099' Type='CT099' Tag='099'
Local Element 'el017' Type='CT017' Tag='017'
Complex Type 'CT099' Data Element Separation='All Elements Delimited' Delimiter='@'
Local Element 'el099.1'
Local Element 'el099.2'
Local Element 'el099.3'
...
Complex Type 'CT017' Data Element Separation='All Elements Delimited' Delimiter='@'
Local Element 'el017.1'
Local Element 'el017.2'
Local Element 'el017.3'
...
Complex Type 'CT0XX' Data Element Separation='All Elements Delimited' Delimiter='@'
Local Element 'el0XX.1'
Local Element 'el0XX.2'
Local Element 'el0XX.3'
...

Please note, however, that I am making some assumptions here.
- I have made CT099 a repeating choice. You should think carefully about whether that is exactly what you require.
- You said 'message built from different kind of lines without any delimiter between the lines. ' Not sure what you mean by that. I assumed that you use CR as a line separator.
- CT099 and CT017 do not need to be global complex types - I just did it that way to make it easy to describe. |
