[vwebdevelopment]

HTML is a markup language that is used to design web pages. It is written in predefined tag elements. Its primary purpose is to display data with focus on how the data looks.
XML is a markup language whose primary purpose is to transport and store data. It is a language that can be used to develop new languages and define other languages. It does not have a predefined set of tags, and allows the developer to customize tags.
