Newsha, I think you'll find that the memory image of a DOM for a 6MB file will be a lot more than 6MB, probably several times larger. In the early days I was certainly warned that for larger files 10MB+ DOM was not really very good because of its size. For our comparators we had to use an array structure that would use less than 6MB memory for a 6MB file so that we can handle large files. Does anyone know the actual ratio of memory size of a DOM relative to the file (of course it varies according to pretty printing and file structure, but approx.)?
