比较XML文件时出现XMLUNIT命名空间异常

Question

我有两个XML文件，当使用XMLUNIT比较它们时，我得到了下面的异常。

Exception in thread "main" org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.

我正在使用下面的代码，它不能像预期的那样工作。

    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

    factory.setValidating(false);

    try {
        factory.setFeature("http://xml.org/sax/features/namespaces", false);
        factory.setFeature("http://xml.org/sax/features/validation", false);
        factory.setFeature("http://apache.org/xml/features/nonvalidating/load-dtd-grammar", false);
        factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);;
    } catch (ParserConfigurationException e) {
        e.printStackTrace();
    }

    XMLUnit.setTestDocumentBuilderFactory(factory);
    XMLUnit.setControlDocumentBuilderFactory(factory);
    XMLUnit.setIgnoreWhitespace(Boolean.TRUE);
    XMLUnit.setIgnoreComments(true);
    XMLUnit.setIgnoreAttributeOrder(true);

如何让XMLUNIT忽略名称空间验证？

删除下面的2行代码使我的代码可以正常工作。

factory.setFeature("http://xml.org/sax/features/namespaces", false);
factory.setFeature("http://xml.org/sax/features/validation", false);
