Generally speaking, RPG doesn't initialize data structure elements unless you specifically tell it to. In the case of the XML-INTO, it doesn't initialize the children of an element until it actually accesses that element. UNLESS you put an INZ on the count variable in question!

d peanutDS ds QUALIFIED
d babyNut likeds(babyNutDS)DIM(10)
d countbabyNut 5i 0 inz

d type 10a
D wieght 10a

That should address your problem. Or if you want to be more explicit, move a zero into the field before you do the XML-INTO. One thing, which is probably just a typo, but your data structure subfield "wieght" is spelled wrong.

The other thing you might want to check into is the XML-SAX opcode. XML-SAX will parse your document and call a handler that you write for each element in the document. That way, if you're only interested in babyNut structures, you can write your handler to only process babyNuts. For me, XML-SAX takes a little more work; it's more event driven than procedural. But it does offer some additional flexibility.


One thing I maybe should add, is that I realise by adding a countpeanut
to my notification datastructure I can
over come this issue by checking for that and then continuing if that is
present, i.e.> 0, but I have a very complex XML file I am reading
through and it would be a lot easier and cleaner if I can just specify
my counts on the elements I am actually interested on rather than a
parent 5 steps up the chain.

My assumption, maybe wrongly, was that any count fields I use in my
datastructures would be set to 0 if the element wasn't present.
