xml - 我如何摆脱 xml :base attribute that is added to my xml document after using xinclude?

Question

我正在尝试使用 xinclude 将 xml 文件解码为 java 对象。我有一个基于我的 jaxb 注释代码文件的模式。这是我的解码代码:

@Override
public T readFromReader(final Reader reader) throws Exception {
    final Unmarshaller unmarshaller = createUnmarshaller();

    final SAXParserFactory spf = SAXParserFactory.newInstance();
    spf.setXIncludeAware(true);
    spf.setNamespaceAware(true);
    //spf.setValidating(true);

    final XMLReader xr = spf.newSAXParser().getXMLReader();
    final InputSource inputSource = new InputSource(reader);
    xr.parse(inputSource)

    final SAXSource source = new SAXSource( xr, new InputSource(reader) );


    try {
        final T object = (T) unmarshaller.unmarshal(source);
        postReadSetup(object);
        return  object;
    } catch (final Exception e) {
        throw new RuntimeException("Cannot parse XML: Additional information is attached. Please ensure your XML is valid.", e);
    }
}

由于我正在调用 xr.parse()，实际的解码没有成功(因为解析关闭了流)。但是，我收到一个解析错误 [Error] file-name.xml:2:66: cvc-complex-type.3.2.2: Attribute 'xml:base' is not allowed to appear in element 'element name '.

我发现这是因为 xinclude 总是向包含的元素添加 xml:base 属性以帮助保留基本 uri。问题是我的模式不允许这个属性。我有什么办法摆脱这个吗？我在网上四处查看，并没有真正看到任何可以轻松实现的东西。

我添加了以下代码行:

// to get rid of xml:base that is brought in with xinclude
spf.setFeature("http://apache.org/xml/features/xinclude/fixup-base-uris", false);
