java - How to update large XML file -

-

rather rewriting entire contents of xml file when single element updated, there better alternative updating file?

i recommend using vtd-xml http://vtd-xml.sourceforge.net/

from faq ( http://vtd-xml.sourceforge.net/faq.html ):

why should use vtd-xml large xml files?

for numerous reasons summarized below:

  • performance: performance of vtd-xml far better sax
  • ease use: random access combined xpath makes application easy write
  • better maintainability: app code shorter , simpler understand.
  • incremental update: occasional, small changes become efficient.
  • indexing: pre-parsed form of xml further boost processing performance.
  • other features: cut, paste, split , assemble xml documents possible vtd-xml.

in order take advantage of vtd-xml, recommended developers split ultra large xml documents smaller, more manageable chucks (<2gb).
