XML Schema Validaiton with sax\Writer.java
How to perform XML Schema validation with sax\Writer.java provided in the Apache Xerces package?
✍: FYIcenter
You can perform XML Schema validation with the sax\Writer.java program
provided in the Apache Xerces package as shown below.
Run the sax\Writer.java program with "-v -s" option to turn on XML Schema validation. If the input XML file does not meet the requirements of its Schema, you will see validation errors:
\fyicenter\xerces-2_11_0\samples>\fyicenter\jdk-1.8.0\bin\java -cp .;..\xercesImpl.jar sax.Writer -v -s UserXsdError.xml <?xml version="1.0" encoding="UTF-8"?> <fyi:User xsi:schemaLocation="http://fyicenter.com User.xsd"> <fyi:ID>ONE[Error] UserXsdError.xml:6:25: cvc-datatype-valid.1.2.1: 'ONE' is not a valid value for 'integer'. [Error] UserXsdError.xml:6:25: cvc-type.3.1.3: The value 'ONE' of element 'fyi:ID' is not valid. </fyi:ID> <fyi:Name>Frank Y. Ivy</fyi:Name> <fyi:BirthDate>1970-01-01+00:01[Error] UserXsdError.xml:8:52: cvc-datatype-valid.1.2.1: '1970-01-01+00:01' is not a valid value for 'dateTime'. [Error] UserXsdError.xml:8:52: cvc-type.3.1.3: The value '1970-01-01+00:01' of element 'fyi:BirthDate' is not valid. </fyi:BirthDate> <fyi:Sex>Male</fyi:Sex> </fyi:User>
The XML file used in the above test is, UserXsdError.xml:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <!-- Copyright (c) 2017 FYIcenter.com --> <fyi:User xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:fyi="http://fyicenter.com" xsi:schemaLocation="http://fyicenter.com User.xsd"> <fyi:ID>ONE</fyi:ID> <fyi:Name>Frank Y. Ivy</fyi:Name> <fyi:BirthDate>1970-01-01+00:01</fyi:BirthDate> <fyi:Sex> Male</fyi:Sex> </fyi:User>
The XML Schema file used in the above test is, User.xsd:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <!-- Copyright (c) 2017 FYIcenter.com --> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:fyi="http://fyicenter.com" targetNamespace="http://fyicenter.com" elementFormDefault="qualified"> <xsd:element name="User"> <xsd:complexType> <xsd:sequence> <xsd:element name="ID" type="xsd:integer"/> <xsd:element name="Name" type="xsd:string"/> <xsd:element name="BirthDate" type="xsd:dateTime"/> <xsd:element name="Sex" type="fyi:sexType"/> </xsd:sequence> </xsd:complexType> </xsd:element> <xsd:simpleType name="sexType"> <xsd:restriction base="xsd:NMTOKEN"> <xsd:enumeration value="Male"/> <xsd:enumeration value="Femal"/> </xsd:restriction> </xsd:simpleType> </xsd:schema>
