DOMException enum

[el...@ni.com]

I am having trouble using the enum associated with the DOMException.  I
would certainly prefer to use the enum when error checking than the numeric
equivalent.  Here is a simplified example of my problem:

try
            {
                  DOMEntityReference*     testRef =
doc->createEntityReference(amp);
            }
            catch(DOMException e)
            {

                  if(e.code == DOMSTRING_SIZE_ERR)
                        cout<<"Some particularly helpful message"<<endl;
            }

Whenver I try to compile this I get

C:
\wormholeitk\supportfiles\plat\xerces-c2_2_0-win32\samples\CreateDOMDocument\CreateDOMDocument.cpp(220)

: error C2065: 'DOMSTRING_SIZE_ERR' : undeclared identifier
Error executing cl.exe.

Error 2065 is as follows:

The specified identifier was not declared.  A variable's type must be
specified in a declaration before it can be used. The parameters that a
function uses must be specified in a declaration, or prototype, before the
function can be used.

What am I missing here?

Do you really mean to catch that exception by value?  Why not by const
reference?

             catch(const DOMException& e)
             {

                   if(e.code == DOMException::DOMSTRING_SIZE_ERR)
                         cout<<"Some particularly helpful message"<<endl;
             }

The enum is declared withing the DOMException class, so it is within that
scope.
