Simple Elements

A Simple element in XML contains only text, no attributes and no child elements.

Example

          <firstname>hari</firstname>

          <middlename>Krishna</middlename>

          <lastname>gurram</lastname>

          <age>25</age>

Above elements are simple elements.

Syntax to define simple elements

<xs:element name=”nameOfTheElement” type=”typeOfTheElement” />

“type” represents the type of the element. XML schema has a lot of built in types like xs:string, xs:decimal, xs:integer, xs:date etc., we will discuss about the data types in later posts.
