xml schema validation error "prefix is not bound"

Tags:

I am entirely new to XML Schema and am trying to get the basics down. Here is my xml schema code (filename: example1.xsd):

<?xml version="1.0"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:sample="http://www.example"  targetNamespace="http://www.example.com"  elementFormDefault="qualified">  <xs:element name="school">   <xs:complexType>     <xs:sequence>       <xs:element name="element1" type="xs:string"/>       <xs:element name="element2" type="xs:string"/>       <xs:element name="element3" type="xs:string"/>       <xs:element name="element4" type="xs:string"/>     </xs:sequence>   </xs:complexType> </xs:element>  </xs:schema>  

Here is the XML document.

<?xml version="1.0" encoding="UTF-8"?>  <sample:school xmlns="http://www.example.com"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="./example1.xsd">        <element1>hello</element1>       <element2>hello</element2>       <element3>hello</element3>       <element4>hello</element4>  </sample:school> 

Upon trying to validate the xml file, I get an error from netbeans that says: The prefix "sample" for element "sample:school" is not bound. [9]

In your XML, you either need to:

A. Remove the sample: prefix from sample:school

or

B. Change the xmlns="http://www.example.com" to xmlns:sample="http://www.example.com" and add the sample: prefix to the rest of the elements (<sample:element1>, <sample:element2>, etc.)
