Add support for SWIFT headers

[bumi]

SWIFT headers like {1:F01AXISINBBAXXXXXXXXXXXXX}{2:I940XXXXXXXXAXXXN}{4: should be supported.
see also issue #8

I want to report that ING in the Netherlands also has MT940 files with such SWIFT headers.

Hi @FooBarWidget thanks for the report. good to know.
Do the headers contain information that you need?
Sadly I am currently lacking time to add this functionality.

[FooBarWidget]

MT940 looks like arcane magic to me so I don't know how to answer that question. :) I haven't been able to parse my files using any Ruby parser library so I've switched to using CAMT053 XML files.

[bumi]

sorry to hear that. maybe we should just strip it by default as the headers are mostly not needed and just cause problems. parsing should work fine if you remove the header.

But if you can use CAMT53 it is the better format to use anyway.
Thanks for reporting and let me know if there is anything that I can help with.

[bumi]

could you provide a sample file of your format?

[FooBarWidget]

I can't provide a full sample, but maybe it's helpful if I provide the beginning (with some info stripped out):

{1:F01INGBNL2ABXXX0000000000}
{2:I940INGBNL2AXXXN}
{4:
:20:P161007000000001
:25:<some IBAN here>EUR
:28C:00000
:60F:C160831EUR1234,56
:61:1609130913D1700,05NTRFEREF//16257002497622
/TRCD/00100/
:86:/EREF/<some description>//CNTP/<some IBAN here>/<some BIC here>
/<vendor name here>///REMI/USTD//<another description>/

It seems the parser bailed out at the first line.

[bumi]

great thanks!

yes, the first 3 lines ({1: ...) are some header data the actual MT940 starts at :20: / after {:4

if you strip that header it should work. but as some banks have this header data the parser should support it.
