YAJL is one of two thing:

1. A processor the reads through a JSON structure and returns values in
nodes.
2. A JSON generator that generates JSON in a buffer.

It has no Object Oriented capabilities so if you want to extract part of a
JSON structure
you are simply using a wrong programming language.

Javascript/node.js support this nativly since JSON is a text notation of a
javascript object
and you are ablte to extract any part of the javascript object and the
serialize it back to
JSON.

So use RPGLE to simple process/generation of JSON and node.js to advanced
process/
generation of JSON. And yes, you may call node.js modules from RPGLE and
vice versa
using profounds connector.

You could just make you're own log as you spin through the array. Or do
you want to save the exact JSON array as it is? That may be difficult.

If that's the case I'd just save the whole thing for the log. Saving a
array node to a string would take a little extra work. If you look through
the YAJL code you may be able to see how to do 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 .
