Andy17 Posted September 12, 2010 Share Posted September 12, 2010 Hey guys, So I have started to learn a bit of XML and saw w3schools having tutorials for both XSD (XML Schemas) and DTD (Document Type Definition) for describing the structure of an XML document. Before I begin learning both of these, I would like to know if it is necessary to know both of these markups, or if one of them is used more than the other. So, should I spend time on learning both of them or just one (if so, which one is most used?). Thanks! Edit: Sorry, this just might have been posted in the wrong forum. There are really some categories missing on this forum. Quote Link to comment https://forums.phpfreaks.com/topic/213216-xsd-and-dtd/ Share on other sites More sharing options...
