Re: Size Limits / know issues with XML-INTO?

Given that the link to the documented limit appears under
Programming>ILE languages>RPG>ILE RPG Programmer's Guide>Creating and
Running an ILE RPG Application>RPG and the eBusiness World>RPG and
XML>Processing XML Documents,

which mentions both XML-INTO and XML-SAX...

I suspect that the limit applies to both parsers...

So for now, if you expect to have to handle large XML docs, EXPAT is
probably the better option.

Well XML-INTO is not a DOM processor - a SAX-like process runs and the run
time then moves the data it finds into the appropriate variables.

But that said I don't know if XML-SAX does fully parse the whole document
before doing anything else.

This is tickling something in my memory. Somewhere in these lists, I
can't remember and can't find where (did some searching just now),
there was at least one discussion about the relative strengths and
weaknesses of the DOM approach vs. SAX approach to XML processing. And
while there was broad agreement that DOM strongly implies "document as
a whole" (and thus, in principle, greater memory requirements than
SAX), I think we concluded that it was a mistake to conflate the
"XML-INTO vs. XML-SAX" picture with the "DOM vs. SAX" picture.

It would not surprise me if you or someone else revealed that both of
the RPG opcodes had some common machinery underlying their
implementations, particularly since they both accept handlers.
