Hi, Ok I made the changes to the XML file. I think im going to use Dom, i read that it allows saving & creating XML files. I need to use this eventually & because I have a short timeframe I just want to get used to one method. IIs this Ok, will Dom Fufil my needs?
Also How would I start to impliment the Dom (for reading files)... dont see a constructor anywhere in the docs...Is it createDOMBuilder ??
