Hi Lilantha, The general rule of thumb is that when loaded into memory, a DOM representation takes around 5 times the size of the input document.
So the DOM generated from your 260MB file will be about 1.3GBytes. That's a big chunk of your available memory used up straight away. I presume that you have run the JVM with the "-Xmx" option, to set the max memory the JVM can allocate? If not, consult your JVM documentation for how to use this option. If you have used "-Xmx" and are still getting "out of memory" then I think that probably is indeed the case, and that you just will not be able to transform that file. You could try increasing the amount of virtual memory available (though that will have horrible effects on the time required to process your file). Is this just a one-off, or are you intending to transform files of that size on a regular basis? Frankly, if you are intending to do this transform often then I think that XSLT is the wrong solution. XSLT is a fine thing, but just isn't going to work on input data like that. And I hate to think how long that transform will take...have you tried to extrapolate from your smaller successful transforms to guess how long a 260MB file will take to process? You might find that it isn't worth trying to get it working if it is going to take a week to finish :-) Note that using "SAX2SAX" doesn't bypass the need to build a DOM representation of the input; XSLT basically requires a DOM. You might want to look at STX as an alternative to XSLT (less features but more efficient esp. for large documents).
