SAXParser不允许Xinclude

Question

我正在试图解组一个包含<xi:include>标记的xml文档。但是SAXParser不允许这样做，即使我具体地告诉SAXParserFactory允许它。

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);

要读取的XML文档

<?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>

当我运行它时，我得到了这个异常：

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XML文档中删除<xi:include>标记时，文件就会被解封。解组程序有一个附加到它的架构。架构不允许<xi:include>。

Answer 1

我使用xmlns:xi="http://www.w3.org/2003/XInclude"，而我应该使用xmlns:xi="http://www.w3.org/2001/XInclude"

问题解决了！
