在Java中将DOM节点呈现为字符串而不指定名称空间

public static String renderToString(Node element) {
    TransformerFactory transformerFactory = TransformerFactory.newInstance();
    Transformer transformer = null;
    try {
        transformer = transformerFactory.newTransformer();
        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
    } catch (TransformerConfigurationException e) {
        e.printStackTrace();
    }
    DOMSource source = new DOMSource(element);
    StreamResult result = new StreamResult(new StringWriter());
    try {
        transformer.transform(source, result);
    } catch (TransformerException e) {
        e.printStackTrace();
    }
    return result.getWriter().toString();
}

我编写了一个测试,它构造了一个

<FIELD ID="1" xsi:type="CharTerm" TERMINATOR=";" MAX_LENGTH="8000" COLLATION="SQL_Latin1_General_CP1_CI_AS" />

这是由以下函数生成的

public static Element createFieldElement(Document doc) {
    Element fieldElement = doc.createElement("FIELD");
    ...
    fieldElement.setAttribute("xsi:type", "CharTerm");
    return fieldElement;
}

为了保持代码的可测试性,是否有一个必须设置的选项或绕过XML名称空间声明的方法?

否则,我将尝试模拟一些函数,以诱使转换器无论如何呈现元素,但我不建议这是一个方便的选项。
