XML XSD Schema Validation Test Result

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, XMLReaderValidator2.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) 2014, HerongYang.com, All Rights Reserved.
-->
 <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 with JDK 1.8:

>java XMLReaderValidator2 dictrionary_invalid_xsd.xml

Error:
   Public ID: null
   System ID: file:///C:/herong/dictionary_invalid_xsd.xml
   Line number: 7
   Column number: 22
   Message: cvc-datatype-valid.1.2.1: 'yes' is not a valid value for 
      'boolean'.

Error:
   Public ID: null
   System ID: file:///C:/herong/dictionary_invalid_xsd.xml
   Line number: 7
   Column number: 22
   Message: cvc-attribute.3: The value 'yes' of attribute 'acronym' 
      on element 'word' is not valid with respect to its type, 
      'boolean'.

Error:
   Public ID: null
   System ID: file:///C:/herong/dictionary_invalid_xsd.xml
   Line number: 11
   Column number: 31
   Message: cvc-pattern-valid: Value '23-Dec-2003' is not facet-valid

      '#AnonType_dateupdateType'.

Error:
   Public ID: null
   System ID: file:///C:/herong/dictionary_invalid_xsd.xml
   Line number: 11
   Column number: 31
   Message: cvc-attribute.3: The value '23-Dec-2003' of attribute 
      'date' on element 'update' is not valid with respect to its 
      type, 'null'.

Fattal error:
   Public ID: null
   System ID: file:///C:/herong/dictionary_invalid_xsd.xml
   Line number: 14
   Column number: 10
   Message: The content of elements must consist of well-formed 
      character data or markup.
org.xml.sax.SAXParseException; systemId: 
   file:///C:/herong/dictionary_invalid_xsd.xml; lineNumber: 14; 
   columnNumber: 10; The content of elements must consist of well-
   formed character data or markup.

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