Can you post the related JSON and identify what you mean by "VAL" - your code references val as a node identifier and you appear to be extracting individual elements from it.

Do you mean that you want the actual JSON string? i.e. inclusive of all the elements within it?

Bradley,

It is a web service call using RXS-XML library the whole JSON Document comes back in a string.
With I then I do this code.

But I want the array element node "VAL" to be logged not docnode.

docNode = yajl_buf_load_tree(%addr(gXmlResponse:*data) : %len(gXmlResponse) : JsonErrMsg);
Node = YAJL_object_find(docNode : 'found');

if YAJL_IS_TRUE(Node);
//
// Update NextPage
//
chain (Subscription_P) ofsupd01 ofsupd01Ds;
if not %found(ofsupd01);
exsr Exitpgm;
endif;

Node = YAJL_object_find(docNode : 'nextPage');
nextPage = YAJL_get_string(Node);

ofsupd01Ds.nextPage = nextPage;
ofsupd01Ds.LastPollDate = %dec(%date():*cymd);
ofsupd01Ds.LastPollTime = %dec(%Time():*ISO);
ofsupd01Ds.LastPollStatus = 'G';

update ofsup01f ofsupd01Ds;

items = YAJL_object_find(docNode: 'items');

i = *zeros;

dow YAJL_ARRAY_LOOP( items : i: val );
Node = YAJL_object_find(Val : 'eventType');
eventType = YAJL_get_string(Node);

clear oftrtv01Ds;
chain (Subscription_P : eventType) oftrtv01 oftrtv01Ds;
if %found(oftrtv01);
if oftrtv01Ds.Program <> 'NA' and oftrtv01Ds.status = 'A';
monitor;
writeJobLog('Calling ' + %trim(eventType) + ' ' + %trim(oftrtv01Ds.Program) + X'25');
program(eventType : val );
on-error;
writeJobLog('*** ERROR *** Calling ' + %trim(eventType) + ' ' +
%trim(oftrtv01Ds.Program) + X'25');
endmon;
endif;
endif;
enddo;
endif;


Val is the one I want to convert to a string which is an Object not a string .

John,

How are you getting the JSON data into your program? From a POST using standard input?

Does anyone know using Scott Klement Json Library how you can convert
an JSON object back to a string so I can log the file ?

I have a json array and I want to log each element within the array to
a file.

Thanks
