The parsing process likely requires more memory than just the size of
the file. I've had similar problems when reading or processing other
files that were significantly above half the memory limit.
You could try to optimize the memory usage - perhaps split the file up
in chunks in temp files and process them one at a time, rather than read
the entire file into memory. Not all XML files can be split like this,
but those that have a long list of identical entities in series (say, an
RSS feed with hundreds of items) can be. You'd just need to add the
opening and closing tags to each chunk.
