dictionary.xsd - A Sample XSD XML Schema File

This section provides a tutorial example of XSD XML Schema file, dictionary.xsd, using XSD statements: schema, element, attribute, simpleType, complexType, etc.

Let's revise my dictionary XML file with XSD link, dictionary_xsd.xml:

<?xml version="1.0"?>
<dictionary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
<!-- dictionary_xsd.xml
 - Copyright (c) 2002-2018 HerongYang.com. All Rights Reserved.
 <word acronym="true">
  <definition reference="Herong's Notes">eXtensible Markup
  <update date="2014-12-23"/>
 <word symbol="true">
  <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>]]>
 <word symbol="false" acronym="false">
  <definition>Capable of being extended.</definition>

And write an XSD XML Schema 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:element name="word" type="wordType" maxOccurs="unbounded"/>
 <xsd:complexType name="wordType">
   <xsd:element name="name" type="xsd:string"/>
   <xsd:element name="definition" type="definitionType"
   <xsd:element name="update" type="updateType" minOccurs="0"/>
  <xsd:attribute name="acronym" type="xsd:boolean" use="optional"/>
  <xsd:attribute name="symbol" type="xsd:boolean" use="optional"/>
 <xsd:complexType name="definitionType" mixed="true">
  <xsd:attribute name="reference" type="xsd:string"/>
 <xsd:complexType name="updateType">
  <xsd:attribute name="date">
    <xsd:restriction base="xsd:string">
     <xsd:pattern value="\p{Nd}{4}-\p{Nd}{2}-\p{Nd}{2}"/>
