Testing Examples of XSD File and XML File

<< XML Parser API - Xerces2 Java Parser

<< XML Schema Tutorials - Herong's Tutorial Examples

This section provides an example XML file assigned with an example XML Schema file (XSD).

Note that tutorial examples given in this section were taken in 2002.

In order to test my XML Schema validator using Xerces2, I wrote this example XSD file, dictionary.xsd:

<?xml version="1.0"?>
<!-- dictionary.xsd
   Copyright (c) 2002 by Dr. Herong Yang. All rights reserved.
-->
<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>

Based on this XSD file, I wrote this invalid example XML file, dictionary_invalid_xsd.xml, with the XSD file assigned through the "xsi" attribute:

<?xml version="1.0"?>
<dictionary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xsi:noNamespaceSchemaLocation="dictionary.xsd">
<!-- dictionary_invalid_xsd.xml

-->
 <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>
