I have similar problem, message with the structure
Header <CR><LF>
repeating message data[0]<CR><LF>
repeating message data[2]<CR><LF>
.
.
.
repeating message data[n]<CR><LF>
footer
I have already developed and tested complex type for the TDS message body structure which is repeated message data,
But message has got header and footer, as advised by jeff the header length is known so this can be parsed.
But How do I take care of the message body end and footer, Has anyone found the solution for the same.
Regards |

Hopefully a moderator will split this off into it's own thread, as even if it's a "similar" problem, it's still likely entirely different.
You need a type for each of HEADER, BODY, and FOOTER.
Then you need to be able to tell the parser how to determine which of those three pieces it's looking for. How this is done depends a lot on a) which parser you are using, and b) what the data specifically looks like.

Thanks moderator for spliting, thanks jeff for the reply....
Message set is of type TDS.
Header is formed using 10 simple type field so header type is complex type.
Repeating message body structure is the complex type.
Footer is formed using 5 simple type field so footer type is also complex type.
But not sure how parser come to know about the end of message body and start of the footer. |

Does the header always start with "J", and the trailer always start with "R"?

yes jeff, we have some pattern for start of the header and footer
e.g. ABCDEF-H for the header and ABCDEF-F for the footer |

Those patterns do not match the data which you posted.
Anyway, if the header, body and footer can be identified by their first N characters, set Data Element Separation to 'Tagged Delimited', and assign a tag to header/body/footer.
Otherwise, set Data Element Separation to 'Use Data Pattern' and set a data pattern on header, body and footer. |
