Unix.select + Stream or ulex

Unix.select + Stream or ulex

[Anastasia Gornostaeva]

Hello.

I attempt to use ulex based xmlparser for xml streaming together with 
Unix.select to manage multiple connections, but I cannot figure out how to
use ulex (and Stream functions) in this case: 

let infds, _, _ = Unix.select infds [] [] time in
if infds <> [] then
  let str = String.create 1024 in
  let size = Unix.read fd str 0 1024 in
     try
        let xml = UlexBased.parser_xml (String.sub str 0 size) in
           process_xml xml    (* the str was enough to have complete xml stanza *)
     with Stream.Failure -> () (* wait for future data *)
  ...

Any idea?

Thanks
