使用JAVA进行EDIFACT映射

Question

I am trying to map EDIFACT files using java.

The data I'm using is encoded and it looks like this: UNBIATB11AMS135682300687X

I'm expecting this format: UNH+1+SBRRES:09:3:1A'

Can anyone please help me figure this out?

Thanks in advance.

Answer 1

Your text seems to contain 0x1D , 0x1F , and 0x1C characters.

If you replace 0x1D with + , 0x1F with : , and 0x1C with ' , you get:

UNB+IATB:1+1A+MS+13568:230+0687+++X'

You probably shouldn't replace, but simply parse using those non-displayable characters, but if you need displayable, you can do this:

s = s.replace('\u001D', '+').replace('\u001F', ':').replace('\u001C', '\'');

Or replace with whatever characters is not otherwise in the data. That is likely why they use those non-displayable characters, because they are guaranteed to not be in the text data. Remember, the computer doesn't care whether a character is displayable, only humans do.
