XSD Validation in Java

Part:   1  2   3 

(Continued from previous part...)

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 dictrionary_invalid_xsd.xml

you will get:

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

This is perfect. It tells you where the error is, and why it's an error.
