tells the web browser about the markup language in which the current page is
written. It is not an element or tag. The doctype declaration is not case-sensitive.
• <html> – This tag is used to define the root element of HTML document. This tag
tells the browser that it is an HTML document. It is the second outer container
element that contains all other elements within it.
• <head> – This tag is used to define the head portion of the HTML document that
contains information related to the document. Elements within the head tag are not
visible on the front-end of a webpage.
• <body> – The body tag is used to enclose all the visible content of a webpage. In
other words, the body content is what the browser will show on the front end

WHY XML?

benefit of xml is that you can use it to take data from a program like
Microsoft SQL, convert it into XML then share that XML with other
programs and platforms. You can communicate between two
platforms which are generally very difficult.
 The main thing which makes XML truly powerful is its international
acceptance. Many corporation use XML interfaces for databases,
programming, office application mobile phones and more. It is due to
its platform independent feature. 12

ADVANTAGES OF XML
XML simplifies data sharing
XML simplifies data transport
XML simplifies Platform change
XML increases data availability
XML can be used to create new internet languages .. Like
XHTML WSDL
