XMLBuilder to XMLSax Help Please

I have created a xml file through xmlbuilder and would like to parse the users input from that file to another file that can be used as a configuration or script.

This could be either an automatic parse
or even through a Click (i.e File.WriteString)

Is this possible?

I have seen it parsed to a listview but I would like this to be a file instead.

Thanks for everyones help.
