Hi,
I need to parse the below message. I just need to read EmpId's from the Message. I have given Tagged Delimted for reading Emp Id's with Identifier as 'EmpId:'. For reading the next EmpId, how can I parse it with our reading all the middle Junk lines. Help on this would be greatly appreciated?
Sample Message goes here...
-------------------------------------
EmpId: 3007 <CR><LF>
-Junk <CR><LF>
&%&^&^^*&*&*^* <CR><LF>
%^^%&%&^%&%^ <CR><LF>
EmpId: 4007 <CR><LF>
Name: Test Name <CR><LF>
-------------------------------------
Thanks,
A Message Broker Developer |

| This can be done, but Tagged Delimited is not the correct approach. Please post an example of the message tree structure that you want to get. Then I should be able to suggest something that works. |

| This ia human readable file. There is no Message tree. What i have given as a sample is the message coming in the file. We need to read that. Is it possible to read thr Provider Id alone without reading all the junk characters...? |

You can't create a partial model. The model must match the entire physical bitstream.
You can create a model that only partly matches the logical structure of the message, with BLOB fields that capture the missing pieces of the physical message and you ignore in your code. |

I know. I was asking for a description of the message tree which you want the MRM parser to produce. You probably thought that the answer was obvious, but it's not.
Anyway, I think your reply to mqjeff has answered my question. You want your message tree to look like this:
| Code: |
MRM {
EmpId = "3007"
EmpId = "4007"
Name = "Test Name"
} |
I'm afraid you will have to make do with this:
| Code: |
MRM {
EmpId = "3007"
Junk = "&%&^&^^*&*&*^* "
Junk = "%^^%&%&^%&%^ "
EmpId = "4007"
Name = "Test Name"
} |
I think a message model like the one below should work. Please try it, debug it using user trace ( not using the debugger ), and let us know how you get on:
| Code: |
EmployeeMessage
Complex Type Composition="Choice", maxOccurs="-1",
DataElementSeparation="Tagged Delimited", Delimiter="<CR><LF>", Repeating Element Delimiter = "<CR><LF>, "TagDataSeparator=":"
Element Name="EmpId", type="xs:string", Tag="EmpId"
Element Name="EmpId", type="xs:string", Tag="Name"
Group DataElementSeparation="All Elements Delimited", Delimiter="<CR><LF>"
Element Name="Junk", type="xs:string"
|
The idea is that the parser first looks for the tags which are known. If none of them are found, it encounters the 'All Elements Delimited' group. But it cannot know whether that group is present in the bitstream, so it must assume that it is there, and parse an instance of 'Junk'. |

Here I think, I have to give the clearcut sample and it's MRM.
Sample message:
----------------------------
EmpId: 3007
&%&^&^^*&*&*^*
%^^%&%&^%&%^
%^^%&%&^%&%^
EmpId: 3007
----------------------------
MRM Message should go like this...
MRM {
EMP
EmpId = "3007"
JunkComplexType
Junk = "&%&^&^^*&*&*^*%^^%&%&^%&%^%^^%&%&^%&%^"
EMP
EmpId = "4007"
} |
