HI All,

=20

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.

=20

=20

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

=20

                        DTDValidator&               x
=3D (DTDValidator&)m_parser->getValidator();

=20

                        DTDGrammar*                           grammar =
=3D
(DTDGrammar*) x.getGrammar();

                        U4                    root_id =3D
grammar->getRootElemId();

                        NameIdPoolEnumerator<DTDElementDecl> elemEnum =
=3D
grammar->getElemEnumerator();

                        while(elemEnum.hasMoreElements())

                        {

                                    const DTDElementDecl& curElem =3D
elemEnum.nextElement();

                                    if(root_id  =3D=3D curElem.getId())

                                    {

                                                //Getting the root
element name.

                                                rootName =3D
(UChar*)curElem.getFullName();

                                                break;

                                    }

                        }

=20

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

=20

Now in 3.0.1, I noticed that the interface getRootElemId() does not
exist in DTDGrammar class anymore.=20

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

=20

Thanks
