I have some code that creates a fairly large xml DOM and writes it off to a file (up to 50-100MB) . It basically creates the DOM and then calls a toString on it and writes it out with ofstream. Is there a way to get streaming output of the generated dom so that it doesn't create the whole structure in memory all at once and then copy it, etc? I will not modify any node after i create it so it can write it out and free up the memory right away. I could write my own xml class that does the xml construction but ... i don't think that's a good idea since i'll probably miss something when it comes down to escaping etc.
