What should I learn after HTML5...What is DHTML & XHTML? what is the benefit?
XML Does Not DO Anything Maybe it is a little hard to understand, but XML does not DO anything. This note is a note to Tove from Jani, stored as XML: <note> <to>Tove</to> <from>Jani</from> <heading>Reminder</heading> <body>Don't forget me this weekend!</body> </note> The XML above is quite self-descriptive: It has sender information. It has receiver information It has a heading It has a message body. But still, the XML above does not DO anything. XML is just information wrapped in tag. You don't have to know a lot about XML, but if you want to became a XML developer you must to know XML. Any question i accept!
After HTML you should learn CSS
Why xml is used as it contains user defined tags. Why do we need as I see in job requirement?
