( #3333=superdoc: print w/ replies, xml ) Need Help??

I won't bet obviousness :)

I've updated question node with example XML and script doing the job. Input file is read again in each of few hundred iterations. I was thinking about reading it once and then make in-memory copy in each iteration, but this will include swap on HDD and definitely won't speed up the code. Another way would be to store all changes write altered version to file, undo stored changes etc. That would save copying, but on the other hand as there are many changes - structure storing changes might be of same size as original. The best would be to somehow write to file original structure line after line and replace fragments on-fly.
