No, once the processor has processed the file, it is done with the file.
There would be no further connection with the file unless you wrote some
code to maintain a connection.  That would be very hard (for a general
case).

If by "see changes" you mean to load an xml file into an editor and look at
its contents, then you have to serialize the in-memory data (a DOM in this
case, right?)  to a file.
