How are SGML HTML and XML similar and different?
XML has many similarities to HTML, but constitutes a more flexible way of marking up data. Like HTML, XML is based on SGML. The difference between the two, very simply put, is that XML merely describes a syntax for markup: the names of the tags are not set in concrete and authors can “invent” them as appropriate.
What are the problems with HTML and SGML?
HTML does not allow one to define new text elements; that is, it is not extensible. XML (extensible markup language) is a simplified form of SGML intended for documents that are published on the Web. Like SGML, XML uses DTDs to define document types and the meanings of tags used in them.
