In this case I disagree with you (about the human readable, not the serialization part where you are right). XML has the advantage of having a lot of really good editors (even graphical ones), adding to that the possibility to make .XSD files to validate your XML (and to help edit them, it's so cool with Visual Studio to write an XML with an XSD reference file...), it's much easier to to not make mistake writting an XML than a custom format where you can look for hours before finding a missing bracket or ";". Another advantage of XML is also that in all programming languages there are good parsers, allowing to create easily a GUI for the configuration files without having to write the parsing part. I thing that the current wave of XML based formats like COLLADA, KML, Open XML and others are a really good thing. Voilà, that was just my two cents on the subject. :) -- Serge Lages http://www.magrathea-engine.org
