no, the file can be converted to a different encoding on the fly, and the parser can't work directly from a file index, it is unfortunately far more complex than that. > >>If I can't re-read part of a file, I could also re-read the whole > >>file, ... > >> > >>Is there maybe a simple way to remember for a xmlTextReader where it > >>is in the current document, ... > > > >Hum, no, ... > >You will iterate on the Read() though, assuming you don't do other > >progress operations, just count them, and then when going through the > >second time run a loop with the same number of Read() you should be > >at the same place if the input didn't changed ! > > > > Just counting the reads sound like an excellent idea! Thanks! That should Just Work, is rather trivial to implement assuming the file doesn't change and you can keep easilly many 'places' in that document, since its just a counter.
