Hi, Jason,
The entityNode itself does NOT maintain the --value--, and if it is
referenced,
the DOMParser will be notified by the Scanner (startEntityReference()), and
it will
decide if entityReferenceNode to be created or not (based on the
fCreateEntityReferenceNodes),
in case this is true, an entityReferenceNode is created, and the entityNode
will setEntityRef() to point to the entityReferenceNode created.
That entityReferenceNode may give you back the -value- of the
entityNode (though
i am working hard trying to find out how it is done).
Besides, if you run your sample with the latest version of XercesLib,
you may find
that those predefined entities are no longer kept in the DocumentType, and
neither the
populateDocumentType().
Regards,
Peiyong Zhang

OK. After digging a bit I find this:
void DOMParser::populateDocumentType()
{
NameIdPoolEnumerator<DTDEntityDecl> entityPoolEnum =
((DTDValidator*)fValidator)->getEntityEnumerator();
while(entityPoolEnum.hasMoreElements()) {
DTDEntityDecl* entityDecl =
&entityPoolEnum.nextElement();
EntityImpl* entity = ((DocumentImpl*)fDocument.fImpl)
->createEntity(entityDecl->getName());
entity->setPublicId(entityDecl->getPublicId());
entity->setSystemId(entityDecl->getSystemId());
entity->setNotationName(entityDecl->getNotationName
());
fDocumentType->entities->setNamedItem( entity );
}
}
So the entities that get created here only have their name set, which
is what I have seen. But nowhere can I find how the child text nodes
get added in some cases.
I'd really appreciate some assistance with this one,
jas.
