once you get comfortable with vtd-xml, few people will ever get back to DOM and SAX...
maybe you want to consider to contribute a vtd-xml based parsing
implementation to Lucene ;-)
Thanks

Thanks everyone for your useful suggestions/links.
Lucene uses DOM and we tried with SAX.
XML Pull & vtd-xml as well as Piccolo seem good.
However, for now, we've broken the file into smaller chunks and then
parsing it.
When we get some time, we'ld like to refactor with the suggested ones.
Erick: We do use Eclipse. But running from CLI gives the same error! May
be there is a way to address the memory issues, but the current idea of
breaking into smaller chunks have worked for now...
Sincerely,
Sithu D Sudarsan

Subject: Parsing large xml files
Hi,
While trying to parse xml documents of about 50MB size, we run into
OutOfMemoryError due to java heap space. Increasing JVM to use close
2GB
(that is the max), does not help. Is there any API that could be used
to
handle such large single xml files?
I am not familiar with that particular code of Lucene, but is it
possible that Lucene is using DOM for this parsing?
If so, one could try to replace it by SAX, and hence get rid of the
OutOfMemory issue.
Cheers
Michael
If Lucene is not the right place, please let me know alternate places
to
look for,
Thanks in advance,
