Re: Passing XML back and forth with RPG and .NET

Use the temp IFS. Scott's EXPAT parser will read directly from an IFS table
and they are very fast. Writing to a physical file is slow. There should be
nothing to writing to the IFS. I have a service program that wrappers
everything that I use. The parsing back would be handled by EXPAT.

You could also pass a 64k varchar but like you said it might be too big.
V6R1 has much bigger limits.

I am at a loss here of a best-practice to pass XML back and forth with RPG
and C#.NET. Originally, I was going to use a temp physical file in QTEMP,
but it seems to be that there should be a better way. The temp file has one
line of the document in one record of the file. To me this seems to add a
lot of extra work that really shouldn't be needed. I am looking for a
two-way communication.

One thought is to pass a 32000 char parameter back and forth, but is that
really a good idea? What happens if the document happens to be bigger than
that? I don't think I would hit that limit so maybe I would be fine?

What about creating a temp IFS file? That seems like more work than is
needed as well.

What are your thoughts?

Obviously, both the RPG and C# programs will be reading and processing the
XML document.

I have x-post this on systemidotnet as well to get both sides. I hope David
doesn't mind.
