I believe this was discussed quite a while back, and the conclusion was
that the following is correct and the simplest:
DefaultHandler* defaultHandler= new DefaultHandler();
parser->setContentHandler(defaultHandler);
parser->setErrorHandler(defaultHandler);
No casts are necessary, and creating superfluous variables is just inviting
trouble (and is inefficient).
At any rate, the example is definitely incorrect.

Please respond to

Hi,
I believe the code sample at the following location
http://xml.apache.org/xerces-c/program.html
Under the heading ->
SAX2 Programming Guide
Constructing an XML Reader
Is incorrect.
The section that reads ->
ContentHandler* contentHandler = new DefaultHandler();
ErrorHandler* errHandler = (ErrorHandler*)
contentHandler;
parser->setContentHandler(contentHandler);
parser->setErrorHandler(errHandler);
I believe should read ->
DefaultHandler* defaultHandler= new DefaultHandler();
ContentHandler* contentHandler= (ContentHandler*)
defaultHandler;
ErrorHandler* errHandler = (ErrorHandler*)
defaultHandler;
parser->setContentHandler(contentHandler);
parser->setErrorHandler(errHandler);
If not the virtual function pointer table contained within errHandler is
incorrect (i.e. is some subset of the contentHandler's virtual methods)
......
Thanks
Will
