如何用batik解析svg到文档？

Question

我的svg喜欢这样：

<svg xmlns="http://www.w3.org/2000/svg" 
xmlns:xlink="http://www.w3.org/1999/xlink">
...
</svg>

不仅仅是一个xmlns，如何在batik中定义xmlns？以及如何解析为Document

String svgNS = SVGDOMImplementation.SVG_NAMESPACE_URI;
File file = new File(svgURI);
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
Document doc = f.createDocument(svgNS, "svg", file.toURI().toString());

上面的代码在运行时有异常：

Exception in thread "main" org.w3c.dom.DOMException: The current document is unable to create an element of the requested type (namespace: http://www.w3.org/2000/svg, name: usrs).
