3. DEFINITION
 Extensible Markup Language (XML) is used
to describe data.
 This ability allows XML to support
hierarchical structures. Element names
describe the content of the element, and the
structure describes the relationship between
the elements

4. DEFINITION
 The basic building block of an XML
document is an element, defined by tags. An
element has a beginning and an ending tag.
All elements in an XML document are
contained in an outermost element known as
the root element. XML can also
support nested elements, or elements within
elements.

<?xml version="1.0" encoding="UTF-8"?>
<conversation>
<greeting>Hello, Guy’s!</greeting>
<response>Stop the planet, I want to get
off!</response>
</conversation>

6. FEATURES OF XML
 XML simplifies data sharing
 XML separates data from HTML
 XML simplifies data transport
 XML increases data availability
 XML simplifies platform change
