Yeah I was interested in making an online veiwer for those .xml files you get when you save the scanner info to .xml file. Unfortunately those files don't link to a .dtd file. I'm wondering if you have one made and you can give me the link so I can download it.
A quick one 've just dashed up now: http://php.swcombine.com/khan/scanners.dtd
Haven't written a DTD for an XML document before to be honest, so it's quite rough. I've made a note for later to read up more on them and prepare them for everywhere else we have XML. Unsure when 'll get time.
