[Q] Extracting the key members of an XmlRpcValue object

[mtp1032]

I need to be able to extract the values from an XmlRpcValue where I do
not know in advance what the keys are, or how many exist. For example,
suppose I have an XmlRpcValue, object, returned by some xml-rpc method,

XmlRpc::XmlRpcValue xmlVal = some_xmlrpc_method(...);

that when printed to std::cout, i.e.,

std::cout << xmlVal << std::endl;

yields the following:

{
eventType: "BIRTH",
mother: "Michelle",
gender: "MALE"
}

Knowing the keys (i.e., 'eventType', 'mother', and 'gender') extracting
the value (i.e., "BIRTH", "Michelle", or "MALE") is straightfoward.
However, suppose I do not know what are the keys? What code could write
to obtain key for each member? In other words, what code do implement
that, when executed, will return the string "eventType", "mother", or
"gender".

Thanks, in advance,

Michael

Michael,

XmlRpcValue is not a standard C++ component. Please refer to the
documentation that comes with your library.

First you need to realize that "xmlprc" is not something defined by
the C++ language, so nobody here necessarily has any idea at all what
you are talking about.

XmlRpc::XmlRpcValue xmlVal = some_xmlrpc_method(...);

What is an object of type XmlRpcValue? Obviously it is defined by
some compiler extension or 3rd party library you are using.

that when printed to std::cout, i.e.,

std::cout << xmlVal << std::endl;

yields the following:

{
eventType: "BIRTH",
mother: "Michelle",
gender: "MALE"
}

Knowing the keys (i.e., 'eventType', 'mother', and 'gender') extracting
the value (i.e., "BIRTH", "Michelle", or "MALE") is straightfoward.

What does the data inside the XmlRpcValue object look like? Without
knowing what the object is, how can you expect anyone here to tell you
how to extract data from it?
