what is XML?..

Answer / sarankumarreddy.c

XML(Extensible Markup Langauge)is all about describing
data.An XML tag is not something predefined but it is
something you have to define according to your needs.Below
is a XML which describes invoice data.
<?XML version="1.0" encoding="ISO-8859-1"?>
<student>
<studentnumber>111</studentnumber>
<studentname>SaranKumarReddy.C</studentname>
<totalmarks>790</totalmarks>
<average>79</average>
</student>

For instance in the above example of student all tags are
defined according to student needs.The XML document is self
explanatory,any one can easily understand looking at the
XML data what exactly it means.

In the above example <student></student> tag is the root
element.Root element is the top most elements for a XML.

XML is case sensitive.
Eg: <student> tag is not same as <Student> tag.
