Hi all!

I'm having some difficulties while modelling a general SWIFT Message which should be used for all types of MT's.
I'm not really interested in validating my messages so all I need to achieve is to put everything in its corresponding elements so I can build logic based on the field blocks.

My problem is with the third block, the User Header.

Sample SWIFT message

{1:F01BANKBEBB2222123456}{2:I100BANKDEFFXXXXU3003}{3:{113:xxxx}{108:abcdefgh12345678}}{4:CRLF
:20:PAYREFTB54302 CRLF
:32A:970103BEF1000000,CRLF
:50:CUSTOMER NAME CRLF
AND ADDRESS CRLF
:59:/123-456-789 CRLF
BENEFICIARY NAME CRLF
AND ADDRESS CRLF
-}{5:{MAC:12345678}{CHK:123456789ABC}

I want to parse the third block and create fields with the names based on the TAG name, ie 113 or 108. Since the third field can contain several different groups I dont want to model every possible field.

For the entire message:

DES= Tagged Delimited
Group indicator= {
Group terminator= }
Delimiter= }{
TDS= :

For the third block:

DES= Tagged Delimited
Group indicator= {
Group terminator= }
Delimiter= }{
TDS= :

Now the first element of the third block gets parsed ok but when the parser comes to the second or the end of the third block it says "MTI. Not all the buffer was used when reading message". How do I model the block so that the elements are dynamically created using the tag names?
In the fourth block, the text block everything works ok, but my guess is that its because I use another delimiter and group identifier than for the entire message.

Thanks in advance!

-- edited, fixed a typo in the third block
