XML XSD Schema Validation Test Result

<< XSD (XML Schema Definition) - XML Validation

<< JDK (Java Development Kit) Tutorials

This section provides a tutorial example on how to run the XML schema validation program, XMLReaderValidator.java. The result provides errors with detailed locations and descriptions.

In order to test my XML schema validator, XMLReaderValidator.java, I prepared the following XML file, dictionary_invalid_xsd.xml:

<?xml version="1.0"?>
<dictionary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xsi:noNamespaceSchemaLocation="dictionary.xsd">
<!-- dictionary_invalid_xsd.xml
     Copyright (c) 2002 by Dr. Herong Yang
-->
 <word acronym="yes">
  <name>XML</name>
  <definition reference="Herong's Notes">eXtensible Markup 
Language.</definition>
  <update date="23-Dec-2003"/>
 </word>
 <word symbol="true">
  <name><</name>
  <definition>Mathematical symbol representing the "less than" logical 
operation, like: 1<2.</definition>
  <definition>Reserved symbol in XML representing the beginning of 
tags, like: <![CDATA[<p>Hello world!</p>]]>
  </definition>
  <update editor="Herong Yang"/>
 </word>
 <word symbol="no" acronym="false">
  <name>extensible</name>
  <definition>Capable of being extended.</definition>
 </word>
</dictionary>

Here is the linked XSD file, dictionary.xsd:

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
 <xsd:element name="dictionary" type="dictionaryType"/>
 <xsd:complexType name="dictionaryType">
  <xsd:sequence>
   <xsd:element name="word" type="wordType" maxOccurs="unbounded"/>
  </xsd:sequence>
 </xsd:complexType>
 <xsd:complexType name="wordType">
  <xsd:sequence>
   <xsd:element name="name" type="xsd:string"/>
   <xsd:element name="definition" type="definitionType" 
    maxOccurs="unbounded"/>
   <xsd:element name="update" type="updateType" minOccurs="0"/>
  </xsd:sequence>
  <xsd:attribute name="acronym" type="xsd:boolean" use="optional"/>
  <xsd:attribute name="symbol" type="xsd:boolean" use="optional"/>
 </xsd:complexType>
 <xsd:complexType name="definitionType" mixed="true">
  <xsd:attribute name="reference" type="xsd:string"/>
 </xsd:complexType>
 <xsd:complexType name="updateType">
  <xsd:attribute name="date">
   <xsd:simpleType>
    <xsd:restriction base="xsd:string">
     <xsd:pattern value="\p{Nd}{4}-\p{Nd}{2}-\p{Nd}{2}"/>
    </xsd:restriction>
   </xsd:simpleType>
  </xsd:attribute>
 </xsd:complexType>
</xsd:schema>

Now run the XMLReaderValidator program:

java -cp .;\local\xerces-2_3_0\xercesImpl.jar XMLReaderValidator
   dictrionary_invalid_xsd.xml

You will get:

Error:

   Message: cvc-datatype-valid.1.2.1: 'yes' is not a valid 'boolean'

This is perfect. It provides a list of errors with exact error locations and full error descriptions.
