Hi,
i'm using the MRM parser with the TDS physical format (WMQI 2.1, CSD04).
my message consits of repeating lines, delimiter is <CR><LF>.
| Code: |
line1<CR><LF>
line2<CR><LF>
... |
One line consists of max 4 fields, delimiter is the <SP> (space).
Field 1 is a repeating field, delimiter is '/'. One line looks like:
...
field1_1/field1_2/field1_3/field1_4 field2 field3 field4<CR><LF>
...
The definition of messageset (one line) is:
-->ListOfLines, compound type elements variable length with delimiter <CR><LF>
-->line elements variable length with delimiter <SP> (space), repeating delimiter <CR><LF>
-->field1 (repeating field, repeating delimiter is '/')
-->field2
-->field3
-->field4
Field1 is mandatory. The other fields are optional. Usually it works fine.
Same incoming messages don't include the field1_2, field1_3, field1_4 field2, field3 and field4, but the delimiter '/' is included. The message looks like:
...
field1_1/<CR><LF>
...
In this case the parser throws an exeption "Not all the buffer was used when reading message".
I would expect, that the parser creates the logical field field1_2 with value NULL.
If the delimiter '/' is the last character before <CR><LF>, the parser doesn't work.
Has anyone an idea? Can't the parser handle "NULL"-fields?
