Pranav,
I am puzzled by your message: you were previously reporting a non-Xerces
exception thrown by the parse() method, now you say you have the same
non-Xerces exception when invoking Initialize(). But, in order to reach
the parse() method, you had to invoke Initialize(), so why does this
crash occur only now?
In the end, your code looks fine and will probably run ok on every
machine I can compile it on; you should *really* start debugging your
code with the VS2005 debugger, after invoking Debug | Exceptions and
checking the "Thrown" checkbox next to the "C++ exception" and "Win32
exceptions" entries.

Hello Alberto,
the XMLPlatformUtils::Initialize() function leads to a crash in
Xerces 2.8
The code is like:
try
{
XERCES_CPP_NAMESPACE::XMLPlatformUtils::Initialize();
}
catch (XERCES_CPP_NAMESPACE::XMLException& e)
{
CString cstrTraceMsg;
cstrTraceMsg.Format(_T("ERROR: Internal DOM Error - An error
occurred during creation of output transcoder. Exception code: %d Msg is :
%s"), e.getCode(),e.getMessage());
TRACE_ERROR(CLString(cstrTraceMsg),ERR_DOM_OPERATION_FAILED);
}
catch(...)
{
TRACE_INFO("CSPVXMLParserWrapper::CreateDOMTree()
XMLPlatformUtils::Initialize - threw an exception");
}
I always get the control into the generic catch block than the XMLException
catch
when could this happen? any idea?
regards,
Pranav

hi alberto,
what is the encoding i have to set for the CT2CA object? how do i
do
this? please let me know
It all depends on what that class does (and being a user defined class,
you should know it): I can only guess it's US-ASCII, i.e.
memBufIS->setEncoding(XMLUni::fgUSASCIIEncodingString);
But you can get better informations by debugging your application and
finding out what exception is being thrown and which part of the parser
throws it.

Hello Alberto, thanks for replying.
1.i do hav an XMLException block but the control does not come here
2. i have deleted the wrapper4inputsource now
3.its just that the m_XMLFileName in this case contains the XML string
itself and not really the file name.
If m_XMLFileName contains an XML string, and you really need to convert
it
to a different encoding using the CT2CA object, you should invoke
setEncoding on the MemBufInputSource to tell the parser to ignore the
encoding declaration contained in the XML stream.
If this also fails, you should just try running the program in the
debugger
and see what exception is really thrown.
Alberto
Is it correct the way the parameters to MembufInput source are data
typed?
We are using VS2005 with Xerces 2.8

A few things that you should check:
1) add a catch handler for XMLException, and check what getMessage
says;
using only the catch(...) will not give you any information on the
real
cause of the error
2) why are you declaring a Wrapper4InputSource object if you are not
using
it?
3) the MemBufInputSource class must be used to hold an XML fragment,
but
you are constructing it around a variable named m_XMLFileName; if this
variable holds a file name (instead of the file content) you should
use
LocalFileInputSource

I have one implementation in Xerces C++ 2.8 where in I have this

TRACE_ERROR(CLString(cstrTraceMsg),ERR_FAILURE);
sifRetCode = ERR_FAILURE;
m_strErrorString = _T("Generic Exception

conforms to the schema");
}
At the m_pDOMParser->parse(*memBufIS); The control goes into the
catch
block.
Can you point out any probs in the code? Without the
Wrapper4InputSource wrap(memBufIS, false);, this code was working in
Xerces 2.2 of C++
