All supports XML! KWord, AbiWord, OpenOffice all stores it’s documents as XML documents, even if some of the solutions are nicer than others what matters is that it is XML. Now you will say that I am a stupid ass hole in hype over XML. Hype is not the point, hype doesn’t matter. What matters is that I can write nicely a document in any of the above applications and then take a command line utility written in whatever I like (mn8, Java, Perl, Python,….) and extract the information and do whatewer I want with it, like posting it on my site with the proper style and format.
Heck I can even make scripts which will allow me to display information as KWord,AbiWord, OpenOffice, KSpread, … documents. Isn’t that nice ?
