what is the difference between html 5 and xhtml

Answer 1

Xhtml is an old ( now ) branch version, more conform to XML specifications ( instead SGML for 'regular' Html )... You shouldn't use it, it's older as Html4 ( XHtml 1.0 and Html 4.01 are identiqual: only few syntax vary, and lower permissivity for xhtml ).
A version 2.0 was in development: it wouldn't be compatible to introduce new 'X'features. Finally development was stoped on 2009 July by W3C to focus on new successor HTML5...
