But for example getting some values from xml doc into textboxes waiting to be modified by the user and then writing values back to xml doc isn't possible with this approach I believe. I was thinking this 2 parse (and 2 serializing operations with SAX writer (horror!)) approach more and now I think it's possible to reduce it 1 parse with serializing to temporary file keeping track of binding positions, then perform only writing (not parsing) temporary file with updates into final document. Something like: serialize to file until binding section is found - keeping track of serialized bytes bind section to variables - don't serialize - mark this point serialize to file until binding section is found - keeping track of serialized bytes bind section to variables - don't serialize - mark this point serialize to file etc. modify variables (wait input from the user) perform update writing previous created file to another file: - write until mark point or eof - call setter method when mark point is found - write until mark point or eof - call setter method when mark point is found - etc. * setter method is setbook() like method in my pseudo code with respect, Toni Uusitalo "And I wish that I was made of stone So that I would not have to see A beauty impossible to define A beauty impossible to believe" - Nick Cave (Brompton Oratory) - romanticist? "There are lots of myths that people have around issues of beauty and attraction, and part of the issue is to stop thinking about things in terms of myth, but to use the tools of neuroscience, and start dissecting and understanding how things actually function," said Dr. Hans Breiter, a psychiatrist and co-author of the study." - The Brain Is Stimulated by Beauty, Study Finds - abcnews.com - scientist?
