[OpenSIPS-Users] [RFC] Deprecating mi_xmlrpc

[Brett Nemeroff]

I presently use either the raw fifo, the UDP fifo or the old XMLRPC method.
They all return the same format which has double colon separated nodes.
It's not easy to parse into an object by any language I know.

I've written parsers for it, but I don't like them. It seems like the
structure isn't well suited for parsing. You ask me if I'm using the
"structured" output. The only structured output I know of today is XML with
the unstructured data in one element. Is there something else?

I do prefer JSON. JSON parsers are a dime a dozen and easy to work with
typically. There isn't a whole lot of bloat, like there is with XML
(religious preference).. I'd like something like this:

[
    {
        "dlg_id": "1234:1234",
        "callid": "aaaabbbcccddd",
        "profile": {
            "foo": "bar",
            "bee": "baz"
        }
    },
    {
        "dlg_id": "9999:5432",
        "callid": "qqqwwwweeerrrr",
        "profile": {
            "foo": "bar",
            "bee": "baz"
        }
    }
]

That's my $0.02.. That being said, there's a very large embedded base
expecting the old format as well, which I think needs to be continued to be
supported until we can give adequate notice that it's being deprecated.

Thanks!
-Brett
