SAXParser不允许Xinclude

问题描述：

我想解组一个内部有<xi:include>标记的xml文档。但即使我具体告诉SAXParserFactory允许它，SAXParser也不允许这样做。SAXParser不允许Xinclude

的Java代码：

SAXParserFactory spf = SAXParserFactory.newInstance(); 
spf.setXIncludeaware(true); 
spf.setNamespaceAwere(true); 

spf.setFeature("http://apache.org/xml/features/xinclude", true); 
spf.setFeature("http://apache.org/xml/features/xinclude/fixup-base-uris", true); 

XMLReader xr = spf.newSAXParser().getXMLReader(); 
SAXSource source = new SAXSource(xr, new InputSource(inputStream)); 
JAXBElement<MyClass> el = unmarshaller.unmarshal(source, MyClass.class);

XML文档阅读

<?xml version="1.0" encoding="UTF-8"?> 
<extension xmlns="http://www.example.com/test" xmlns:ext="http://www.example.com/test" xmlns:xi="http://www.w3.org/2003/XInclude"> 
    <visibility> 
     <resourceConstraints> 
      <resourceConstraint ext:resourceId="resourceOne"> 
       <role ext:show="true">AdminUsers</role> 
      </resourceConstraint> 
      <resourceConstraint ext:resourceId="resourceTwo"> 
       <role ext:show="true">AdminUsers</role> 
      </resourceConstraint> 
     </resourceConstraints> 
     <xi:include href="extraContent.xml" /> 
    </visibility> 
</extension>

当我运行它，我得到这个异常：

org.xml.sax.SAXParseException; lineNumber: 12; columnNumber: 50; cvc-complex-type.2.4.a: Invalid content was found starting with element 'xi:include'. One of '{"http://www.example.com/test":resourceConstraints}' is expected.

当我从删除<xi:include>标签XML文档，文件解组就好了。解组器附有一个模式。模式不允许<xi:include>。

答

我用xmlns:xi="http://www.w3.org/2003/XInclude"，而我应该用xmlns:xi="http://www.w3.org/2001/XInclude"现在

问题是固定的！
