Pinned topic Type tree and mapping for iso 8583

‏2012-08-17T10:10:20Z |
Hello WTX experts,

I am having trouble in creating type trees for an ISO 8583 message. ISO 8583 messages have some formats

There will be a hex number, whose bit position(If set 1), will determine the presence of fields

0110 0000 0000 0000 0000 1000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000   6     0    0    0    0    8    0    0    0    0    0    0    0     0    0   0

The above(6000080000000000 in hex) means field 2, 3 and 21 are present in the input message, as those bits are set to 1.

Now each of the field may be defined like below

field no=
"2" charlength=

means it is a variable length field and the first two characters detrmine the length

field no=
"3" total=

means it is a fixed length field of four characters.

<field no=
"21" charlength=
"2"> <subfield no=
"1" total=
"3">fixed</subfield> <subfield no=
"2" charlength=
"2" idcode=
"ABC">variable</subfield> </field>

means field 21, length is determined by the first two characters, inturn it consists of subfields. The variable length subfield will start with a particular code(ABC above), followed by the character length, the character length can be zero

If anyone has type tree similar to the above, please let me know. I am trying to convert this message to xml and vice versa using WTX.

    I heard that SWIFT protocol messages follow almost similar structure. That also copuld be helpful to us.

    Hi Jaango,

    Did you ever succeed in building the ISO8583 type tree? If so, could you share it?
