Subject Replacement for 2.7.0 depecated API getRootElemId in 3.0.1
Date Tue, 07 Jul 2009 04:31:28 GMT
HI All,


I am upgrading Xerces from 2.7.0 to 3.0.1. I am having a problem when I
am trying to get the root element for a given DTD. Your inputs are
appreciated to fix this upgrade issue.



When using 2.7.0, I have the following piece of code to get the root
node of the DTD:


                        DTDValidator&               x
= (DTDValidator&)m_parser->getValidator();


                        DTDGrammar*                           grammar =
(DTDGrammar*) x.getGrammar();

                        U4                    root_id =

                        NameIdPoolEnumerator<DTDElementDecl> elemEnum =



                                    const DTDElementDecl& curElem =

                                    if(root_id  == curElem.getId())


                                                //Getting the root
element name.

                                                rootName =





In the above code, m_parser is an instance of SAXParser, and it parse an
XML with a DTD associated with it using <!DOCTYPE .../>.


Now in 3.0.1, I noticed that the interface getRootElemId() does not
exist in DTDGrammar class anymore. 

What is the alternative way to get the root element? Can anyone point me
to the new interface?
