What are the differences between HTML and XML languages?
HTML vs. XML. If you know HTML (as opposed to the newer XHTML), it would be a good idea to understand the critical differences between XML languages and old-style HTML. Although XML languages and HTML have many similarities, they differ in many respects. Perhaps the most fundamental is that HTML is a markup language itself, with a list of tags that browsers like Internet Explorer and Mozilla Firefox have been programmed to (usually) understand. But XML is a way of making markup languages and doesn’t specify what the tags in those languages are (just how they’re made). When you’re using the ECEn Web XML language, however, we’ve already defined the tags. So as far as the ECEn web pages’ XML goes, the most noticeable difference from HTML is that there are different tags. In addition to that major difference, there are several other minor differences that have to do with the rules XML imposes on XML-based markup languages.
