Hi, I think there's something we need to make clear about XML. The only reason I was using XML in Overflow is that I didn't want to spend too much time writing a parser. I'm storing all the info as objects (UINode, UINetwork, ...) and use the XML only for load/save (I use lib-xml as a black box and don't care how it's saved). This is why I don't understand everything that's going on on this list about XML... am I missing something? Jean-Marc
