[Question] How to do incremental parsing?

["Xu, Mousheng (SEA)" <Mousheng.Xu@sea.celltechgroup.com>]

Dear all,

A problem of all the current XML parsers is that they at least read the
whole XML document into the input stream, which can consume a lot of memory
when the XML is big (e.g. 1 GB).

One way to get around the problem would be to read the XML file into memory
gradually and when needed. I would like to build such a DOM parser, but I am
not familiar with the design of the Xerces XML parsers. Could someone give
me a suggestion on how to tackle on the problem? The most critical part
would be the method to parse an element. If reading the whole document into
memory is inevitable, then I would like to borrow the method which parse the
input stream to get the next element.

Your help is highly appreciated.

Thanks in advance.
