XML Parser for embedded system

XML Parser for embedded system

[Schumacher]

Hello,

I am looking for a XML parser in Ada that can
be used in an embedded system.
It should be a parser that has a deterministic timing
behaviour and  memory consumption e.g. it
should avoid any kind of recursive function calls.

I would like to use it for reading simple nested data
structures up to a given predefined nesting level. So it
is not necessary that is supports the complete XML
standard. A small subset should be sufficient.

Is there anyone who knows such a tool?

With kind regards.

That's a pretty tough requirement; deterministic timing on arbitrary
input data?

Ok, not _totally_ arbitrary. Still, is there a limit on how many
structures are in the file?

On the other hand, the limit on nesting probably limits any recursion
to a known value; would that be acceptable?

GtkAda comes with a subset XML parser that may meet your needs. I
don't remember if it uses recursion.
