parser feature fgXercesUserAdoptsDOMDocument
Hi,
I have a question regarding the fgXercesUserAdoptsDOMDocument feature of
the xerces parser. It doesn't appear to work, I create a parser with the
code below. If I attempt to set the feature it appears to work fine
however it doesn't change the behaviour of the parser and if I call
getFeature or canSetFeature for the same feature it throws a not found
exception.
I'm using xerces 2.1 on solaris 2.6/2.8 with g++ 2.95.3.
DOMBuilder* parser =
DOMImplementationRegistry::getDOMImplementation(gLS)->createDOMBuilder(DOMImplementationLS::MODE_SYNCHRONOUS,0));
parser->setFeature(XMLUni::fgXercesUserAdoptsDOMDocument, true);
Am I doing something wrong or is this feature broken? Without this I
have to keep the parser instance around for a lot longer than is needed
which is a bit messy and inconvenient in my app.
thanks.
Gary.

Hi Gareth,
The parser does not seem to relinquish ownership of the document, I am
also concerned over the fact that calling setFeature does not raise an
exception while getFeature or canSetFeature both raise a not found
exception for the same feature (fgXercesUserAdoptsDOMDocument).
I'll try your method thanks.
Gary.

Hi,
when you say it does not change the behaviour what do you mean?
What you should see is that when you delete the parser it does not delete
the document. The following code works for me:
parser->parse(gXmlFile);
DOMDocument *doc = parser->getDocument();
parser->adoptDocument();
std::cerr <<
XMLString::transcode(doc->getDocumentElement()->getNodeName()) <<
std::endl;
delete parser;
std::cerr <<
XMLString::transcode(doc->getDocumentElement()->getNodeName()) <<
std::endl;
