    A very simple XML data transfer protocol is described at
    http://www.ioserver.com/xmlcfg.htm and is probably all you need.

    For something more complex, there is an established protocol for
    sending automation XML data used in OPC. See
    http://www.opcfoundation.org/ but you have to be a member of the OPC
    Foundation to download the spec. For more links, see the OPC
    Programmers' Connection page at
    http://www.opcconnect.com/xml.php#xmlspec But don't come to me for help
    -- I'm only just getting into this too!

    Be warned that there are current patent disputes over use of XML in
    control systems. IANAL.
