I think HTML is best for web pages.

XML was designed to transport and store data.
HTML was designed to display data.
What is XML?
XML stands for EXtensible Markup Language
XML is a markup language much like HTML
XML was designed to carry data, not to display data
XML tags are not predefined. You must define your own tags
XML is designed to be self-descriptive
XML is a W3C Recommendation
The Difference Between XML and HTML
XML is not a replacement for HTML.
XML and HTML were designed with different goals:
XML was designed to transport and store data, with focus on what data is
HTML was designed to display data, with focus on how data looks
HTML is about displaying information, while XML is about carrying information.
XML does not do anything
Maybe it is a little hard to understand, but XML does not do anything. XML was created to structure, store, and transport information.
But still, this XML document does not do anything. It is just information wrapped in tags. Someone must write a piece of software to send, receive or display it.
XML allows the author to define his/her own tags and his/her own document structure.
XML is Not a Replacement for HTML
XML is a complement to HTML.
It is important to understand that XML is not a replacement for HTML. In most web applications, XML is used to transport data, while HTML is used to format and display the data.
