Hi,
I am trying to use JAXB in our project in a way such that
the xml document is not loaded completely in memory while unmarshalling. I use
the SAXReader and created a pruning ElementHandler which unmarshalls the org.dom4j.Element in
the onEnd method whenever the specified ElementPath is encountered.
Works great, but now I need to replace a small
part of this xml file (unmarshall an element tree, change the unmarshalled object and marshall
it back to the document), also without having the complete
document in memory.
I could also use an ElementHandler, which replaces the Element that
needs to be modified, but how can I write the correct structure back to
the xml file?
I know the XMLWriter is able to handle SAX events which are generated
by the SAXReader, but something needs to filter these events whenever the
ElementHandler has to perform the replacement ((un)marshalling) first.
Please advise.
Wonne
PS: I already tried to implement an extension of the SAXContentHandler, but
that requires the ElementStack to be public and I'd need an additional method in
it...
