Hi,
I'm trying to find the best solution to progressing a very large XML file.
This XML file is filled with independent elements which i want to unmarshall
one at a time because of memory constraints (the file is about 60GB).
<BIND-Interaction-Set>
<BIND-Interaction>
...
</BIND-Interaction>
....
....
</BIND-Interaction-Set>
I've tried to build individual DOM documents from a SAX stream...and that
works ok (using transformations), but then JAXB won't unmarshall it. It
seems that it gets a nullpointerexception in the unmarshaller because the
localName in startElement() is null.
here's some sample code
any better approaches would be appreciated
from my content handler's endElement()
if(localName.equals("BIND-Interaction")) {
System.out.println("end of interaction");
consumer.endDocument();
Document doc = getDocument();
JAXBContext jc = JAXBContextManager.getContext();
Unmarshaller u = jc.createUnmarshaller();
u.setValidating( false );
BINDInteraction o =
(BINDInteraction)u.unmarshal( doc );
}
from the contentHandler's startElement
try{
TransformerHandler handler =
factory.newTransformerHandler();
setConsumer(handler);
result = new DOMResult();
handler.setResult(result);
consumer.startDocument();
thanks,
Marc
