xml : how to reference a .xsd file at .xml file?

Question

I want to see xml file in browser as I define in .xsd file. Please check the following two files for me and point out what do I need to do. These two files are under same folder.

employee.xml

 <?xml version="1.0"?>  <employee xmlns="http://www.w3schools.com"            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"            xsi:schemaLocation="employee.xsd">    <firstname>John</firstname>   <lastname>Smith</lastname> </employee> 

employee.xsd

<xs:element name="employee">   <xs:complexType>     <xs:sequence>       <xs:element name="firstname" type="xs:string" fixed="red" />       <xs:element name="lastname" type="xs:string"/>     </xs:sequence>   </xs:complexType> </xs:element> 

Answer 1

You made two errors: one in the schema file and another in the syntax of the value of the xsi:schemaLocation attribute of the XML file.

The main error is that your employee.xsd file is only a fragment of the XML Schema. You should complete the contain of the employee.xsd. For example,

<?xml version="1.0" encoding="utf-8"?> <xs:schema targetNamespace="http://www.w3schools.com/RedsDevils"     elementFormDefault="qualified"     xmlns="http://www.w3schools.com/RedsDevils employee.xsd"     xmlns:xs="http://www.w3.org/2001/XMLSchema">      <xs:element name="employee">         <xs:complexType>             <xs:sequence>                 <xs:element name="firstname" type="xs:string" fixed="red" />                 <xs:element name="lastname" type="xs:string"/>             </xs:sequence>         </xs:complexType>     </xs:element> </xs:schema> 

and employee.xml:

<?xml version="1.0" encoding="utf-8"?> <employee xmlns="http://www.w3schools.com/RedsDevils"           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"           xsi:schemaLocation="http://www.w3schools.com/RedsDevils employee.xsd">      <firstname>John</firstname>     <lastname>Smith</lastname> </employee> 

Because you define default namespace in the XML file, the schema location attribule xsi:schemaLocation must consist from the the namespace and the path to the schema devided with the blank. I changed the namespace name so that it will be a little more unique: "http://www.w3schools.com/RedsDevils" instead of "http://www.w3schools.com".

At the end I can add that the XML file employee.xml not corresponds to the schema employee.xsd because the element <firstname>John</firstname> has the value other as red, but probably exactly this you wanted to test.
