I doubt you will be able to gain much performance trying to split the
file and use multiple threads to parse the file. You'll waste a lot
of time trying to split the XML into separate valid documents.
However, if you're using SAX, you could easily spawn threads in your
handlers to do whatever you need to do with the XML data. This way
the parser will go through the document as quickly as possible
letting your handlers work asynchronously. This could be difficult to
synchronize if your handlers are dependent on each other for data,
however...

Hello,
I was wondering if it is possible to split a very large XML file (100
megabytes) into several smaller size chunks and then run several SAX
parsing threads on each of the chunks? The problem I having trying to
conceptualise in mind is how to avoid the situation where I split the
large XML file in the wrong place and thus leaving two of the threads
with incomplete information. I reckon I need to run a pre-processor on
the file to determine where to spilt it....
Thanks in advance for any ideas or pointers.
Cheers,
Saad..
