Parsing huge XML file(>65 mb)

[sudeep jha]

Hi all,
I am thinking of using SAX parser to parse the XML file.
Can anyone suggest better approach for this?
Also,eclipse is getting crashed.So, is there anyway that I can see the visual representation of XML file i.e node-tree?

Thanks.

This question comes up all the time - I really should have a canned answer - anyway,
the answer depends on the following:

What do you need to do with the XML document?

Display it
Modify it
Extract specific bits without modifying it
Convert some or all of the contents to a new document format - XML? HTML? PDF?

Please amplify.

Personally I use XML SPY to look at large XML documents nicely formatted - I think they have a free sample version.

Ok, that is one of the simpler problems!

You can use SAX style processing which will be fast and use little memory but requires thinking in terms of events. With SAX it is up to you the programmer to track the "current" location the parser is working on so you will know when the bits you need are about to be parsed.

You probably want to check out vtd-xml for parsing large XML files...
