Okay - I've added XML-RPC data support to my JS serializer extensions. But
although the system does seem to be well supported it also seems to be
poorly documented. ;^)
Right now I'm only creating object-to-string serializers so my solution
doesn't actually implement the full method call - it just creates a single
the "<data>" tag from any JS object.
Some questions, if you have the time:
+) The system doesn't support explicit nulls (which is fine) but how should
a serializer react to them? I can see at least a few ways for handing this:
- Convert a null into an empty value: <value></value>.
- Convert a null into an empty string: <string></string>.
- Throw an error.
I've assumed the first solution (which I think should work across
implementations) but it seems odd that this is left the impelementation.
+) The date format for an implementation is sketchy. I've made the
assumption that dates will be serialized into UTC dates (with the specified
trailing "Z") but I see than other implementations either use local time or
don't use the trailing Z to indicate UTC.
Any idea about what's "right"?
+) String formatting seems... odd. The spec claims that only ampersands and
less-than signs should be escaped - is this right? Not even greater-than
signs? Nothing for control characters?
That's about it...
Anyway I've added the serializer to the JS stuff I've been doing and
provided examples and source code here:

If you have some time I'd much appreciate you going over my XMLRPC
implementation to see if it measures up.
