I am on thesis on archiving *huge* quantities of xml-signed data.
Among other things I have to write a single xml file more than 4 Gb size
(1 dvd) so I decided to use Sax.
Since the Xerces default content handler does not have a flush() method
(it keeps everything in memory until the endDocument() method call), I
changed to Dom4j XmlWriter and then I changed again to Gnu Jaxp
XmlWriter, because Dom4j does not produce canonalized output.
Now I would like to send the canonalized sax events to a digester in
order to produce the document hash and then prettyprint the sax events
into an outputstream (the final file).
First question:
Do you think that I chose the right approach?
Second one:
How can I send the XmlWriter events through an XmlFilter (I would prefer
not to use the Gnu Jaxp pipeline package: I would like to write
implementation independent code as far as possible), since XmlWriter
does not implement the XmlReader interface? Should I extend the
XmlWriter to do implement it?
Thank you in advance, Bye
