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" xsi:noNamespaceSchemaLocation="dictionary.xsd"> <!-- dictionary_xsd.xml - Copyright (c) 2002-2018 HerongYang.com. All Rights Reserved. --> <word acronym="true"> <name>XML</name> <definition reference="Herong's Notes">eXtensible Markup Language.</definition> <update date="2014-12-23"/> </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> </word> <word symbol="false" acronym="false"> <name>extensible</name> <definition>Capable of being extended.</definition> </word> </dictionary>
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: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>
