我使用JAXB来解析xml' s。我有一个如下的模式,以及在此模式上定义的两个xml文件a.xml和b.xml。 a.xml与b.xml通过xi:include xml标记有依赖关系。请提交以下示例以获取更清晰的数据
I have followng schema definition:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="Task">
<xs:complexType>
<xs:sequence>
<xs:element ref="Details" minOccurs="1" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="Details">
<xs:complexType>
<xs:sequence>
<xs:element name="NAme" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
以下是两个xml文件:
A.XML:
<?xml version="1.0" encoding="UTF-8"?>
<Task xmlns:xi="http://www.w3.org/2001/XInclude">
<Details>
<xi:include href="b.xml"/>
</Details>
</Task>
B.XML:
<?xml version="1.0" encoding="UTF-8"?>
<Detail>
<Name>Name1</Name>
</Detail>
<Detail>
<Name>Name2</Name>
</Detail>
现在我使用JAXB SAXFactory解析它:
JAXBContext jaxbcon = JAXBContext.newInstance("schema-definition-jaxb-files");
unmar = jaxbcon.createUnmarshaller();
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setXIncludeAware(true);
XMLReader xr = spf.newSAXParser().getXMLReader();
SAXSource source = new SAXSource(xr, new InputSource(new FileInputStream(xmlfilename)));
Object obj = unmar.unmarshal(source);
解析成功,但 Details JAXB标记对象为null。无论如何,a.xml文件中的xi:include标记都没有展平。任何想法?

试试这个,它肯定有效:
public class Test {
public String include;
public static void main(String[] args) throws Exception {
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setXIncludeAware(true);
spf.setNamespaceAware(true);
XMLReader xr = spf.newSAXParser().getXMLReader();
SAXSource src = new SAXSource(xr, new InputSource("test.xml"));
Test t = JAXB.unmarshal(src, Test.class);
System.out.println(t.include);
}
}

你应该添加
spf.setNamespaceAware(true);
