I don't think there could be a single "recommended" way to do this. It
all depends on your requirements. For some application using raw sockets
could be a perfectly reasonable approach. While other may requires
something as involved as ASIO. Generally, I think it has much more
to do with the kind of communication you will be doing: multiple
sockets or single socket, single/multithread-handling of connections,
blocking/non-blocking/asynchronous I/O, etc.

As a generally guide, I would suggest that you keep it simple, at
least at the beginning (e.g., blocking raw socket).

No, there is no automatic (more like auto-magical) way.

In XML, NULL ('\0', U+0000) is an invalid character (both in XML 1.0
and 1.1) which makes it a convenient document delimiter.
