If there are any C++ programmers out there that
need
to work with XML, it will be worth a moment of
your time
to see how this works.
This example was tested in
Linux/Sun/NT
gcc and VCPP makefiles and source are
included.
It creates a run time object model from XML
input.
A small tight framework allows you to create
objects
from an XML input stream.
Download the "XML Integration Toolkit" 800k
here's a small snippit for creating objects from
XML input.
------------------------------------------------------------------------------------
ObjQuery<MyCustomer>
qry(&broker, "MYXMLInputFile.xml");
ObjResultSet<MyCustomer>
&resultSet = qry.Execute();
MyCustomer
*pCust;
while ( ( pCust = resultSet.next() ) != 0
)
{
// For each MyCustomer
object returned in the query....
}
--------------------------------------------------------------------------------
here's a small snippit for populating objects
that already exist.
--------------------------------------------------------------------------------
MyCustomer
m;
m.FromXML(pzMyXMLBuffer);
--------------------------------------------------------------------------------
or converting an objects state into XML
--------------------------------------------------------------------------------
MyCustomer
m;
m.m_name="foo";
m.ToXML(pzMyXMLBuffer);
--------------------------------------------------------------------------------
<MyCustomer> is derived from a simple base
class
with a virtual method that defines XML-Object tag
mappings.
MFC Dialogs derived from this type can
"UpdateData"
so to say directly from XML into
member CStrings
that
are DDX bound to the GUI.
CORBA and RougeWave applications in Unix
likewise
can serialize directly into RWCStrings and load
object
state with almost-no overhead.
