Not really. It's pretty easy to prove that a full XML parser is computationally more complicated (and hence slower and more bug prone) than most 'obvious' flat text file formats. | I see it as a way to abstract away the | configuration and utilize an existing library to handle the parsing. | If we do want to eliminate outside dependencies (which I think is an | extremely valid point and concern), then we could internally | implement a different configuration format that is easier to parse. Interacting with an XML library is around the same degree of difficulty as writing a simple flat text parser. Remember that if you're using XML, you have to be able to handle *all* the fancy XML nonsense, including DTD voodoo and processor directives. The only 'advantages' to XML are that you can partially validate the syntax (but not the contents) of a file and that by writing a really complicated XSLT mess you can transform it into a different XML file. The former is a duff argument because a) the only reason you need validation is because XML's syntax is so complicated and b) you can't validate CDATA things anyway. The latter is silly because you can use sed, grep, cut etc on any sane textfile format, and it's far easier than XSLT. | I'd probably go for something similar to the samba/gdm config files | if we were to go down this road: <snip> Much saner. -- Ciaran McCreesh : Gentoo Developer (Vim, Shell tools, Fluxbox, Cron) Mail : ciaranm at gentoo.org Web : http://dev.gentoo.org/~ciaranm
