我有一個Java xml驗證的問題。java xml驗證JDK 1.5 JDK 1.6的差異
我有以下的xsd:
<?xml version="1.0" encoding="utf-8"?>
<xsd:schema elementFormDefault="qualified" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="TEST">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="LAST_NAME">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:minLength value="1" />
<xsd:maxLength value="30" />
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="FIRST_NAME">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:minLength value="1" />
<xsd:maxLength value="20" />
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="DOB" nillable="true" type="xsd:date" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
和xml:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<TEST xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<LAST_NAME>Lastname</LAST_NAME>
<FIRST_NAME>Firstname</FIRST_NAME>
<DOB xsi:nil="true"/>
</TEST>
我的驗證的(簡化)代碼:
boolean valid=true;
try {
Source schemaSource = new StreamSource(xsdInputStream);
DocumentBuilder parser = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = parser.parse(xmlInputStream);
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = factory.newSchema(schemaSource);
Validator validator = schema.newValidator();
try {
validator.validate(new DOMSource(document));
} catch (SAXException e) {
logger.log(Level.INFO, e.getMessage(), e);
valid = false;
}
} catch(Exception ex) {
logger.log(Level.SEVERE, ex.getMessage(), ex);
valid=false;
}
的testprogram有不同的行爲JDK 1.5和JDK 1.6。 xml在JDK 1.5中有效,但在JDK 1.6中無效。錯誤消息如下:
Element 'DOB' is a simple type, so it cannot have attributes, excepting those whose namespace name is identical to 'http://www.w3.org/2001/XMLSchema-instance' and whose [local name] is one of 'type', 'nil', 'schemaLocation' or 'noNamespaceSchemaLocation'. However, the attribute, 'xsi:nil' was found.
哪個JDK是正確的?如何更改xml/xsd在兩者中都有效?
thx。 setNamespaceAware(true)解決了我的問題。 – asalamon74 2009-08-28 19:08:50
