XHTML is Extensible HyperText Markup Language. l XHTML was launched by the w3c organization in 2000 to enhance HTML. It was originally intended to replace HTML, but it was found that there were too many web pages written in HTML on the Internet, so it failed! It can be understood that it is an upgraded version of HTML (HTML4.01). l XHTML has a more rigorous code structure and is an application based on XML. XML is Extensible Markup Language (Extensible Markup Language) l XML is a description of data information. HTML is the description of the data display. l XML code regulations are more strict. For example, if the tag does not end, it is considered an error. l The XML specification can be interpreted by more applications and will become a universal data exchange language. l Each server and framework uses XML as a configuration file.
