Re: parsing varying length field from XML file using RPGLE program

ok,after few corrections:-

Decrypted value using AES128 algorithm from a input xml file using RPGLE
program:-

Hi,

When I am trying to read input xml file which has 'encodedexchangetoken'
value in it then using AES128 algorithm interactively it works well like 1)
i issue chgjob ccsid(37) 2) then call qsys/qp2term 3) then i execute this
command :- echo
'u3VtNgfyWU9faZc3Iaa8ZWbE5UZCfmC17yA4MyW0ghflt9dNQNDpCcgMZiG/kXPE4vv2CHL
93B4iKiODHxxdVA==' | openssl enc -d -aes-128-ecb -K
363631653237354f494d31554
c594c4a -nopad -nosalt -base64 -A

which gives me decrypted value as
"707fbe32-0dbc-41e0-888f-5bc40de8c20d2P9AMPCTQ4CZ"

so the same functionality when i am trying to achieve using below RPGLE
program it gives me this error which i get during debug the value of record
field:-

I think I don't need to make a string as in cmd in debug mode i can see
whole long command is coming but ideally value is record is not coming as
decrypted value.
it comes like below in debug mode also one ting i have noticed is that the
pipe symbol is not coming like '*|*' as I have coded in my program where
as in debug mode it gets converted like ' *¦* ':-
how did it get changed ?
That might be the cause of openssl is not working i guess?

RPG is great for building strings. You just use "+".

Take a look here:

https://www.code400.com/forum/forum/iseries-programming-languages/rpg-rpgle/10489-concat-message-into-one-string
.

You could build you cmd string in a series of statements and that might
make debugging easier.

*Something* like this:

cmd = 'echo ' + '''' ;
cmd = %trim(cmd) + encodedexchange;
cmd = %trim(cmd) + ' whatever'
etc etc etc
cmd =%trim(cmd) + '''';

In debug you can go line by line examine cmd and see if it has waht you
want.
%trim removes leading and trailing blanks.

You've not coded a lot of RPG, have you?
