employee.xml

<?xml version="1.0"?>  
<!DOCTYPE employee SYSTEM "employee.dtd">  
<employee>  
  <firstname>phptpoint</firstname>  
  <lastname>Noida</lastname>  
  <email>phptpoint@gmail.com</email>  
</employee>

We will provide a detailed description of the scheme file, XML schema testing, XML schema data types and XML parsers in this XML tutorial.

Let's have a look at an example of XML using XSD.

<?xml version="1.0"?>  
<employee  
xmlns="http://www.phptpoint.com"  
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
xsi:schemaLocation="http://www.phptpoint.com employee.xsd">  
  <firstname>phptpoint</firstname>
