Galera estou lendo esse XML. A minha dificuldade é saber como faço para pegar o valor do atributo name do elemento UML:Class. Gostaria de saber como faço para pegar o atributo. Estou usando XPath

<UML:Namespace.ownedElement>
<UML:Class xmi.id = '127-0-1-1--57e073b3:131afce9b99:-8000:0000000000000866'
name = 'Carro' visibility = 'public' isSpecification = 'false' isRoot = 'false'
isLeaf = 'false' isAbstract = 'false' isActive = 'false'/>
</UML:Namespace.ownedElement>
</UML:Model>
</XMI.content>
</XMI>Usando o seguinte código:
DocumentBuilderFactory dom = DocumentBuilderFactory.newInstance();
dom.setNamespaceAware(true);
DocumentBuilder builder = dom.newDocumentBuilder();
Document document = builder.parse("/home/rafael/argo.xmi");
XPath xPath = XPathFactory.newInstance().newXPath();
XPathExpression exp = xPath.compile("//XMI.content/UML:Model/UML:Namespace.ownedElement/UML:Class/@name");
Object o = exp.evaluate(document, XPathConstants.NODESET);
NodeList nodes = (NodeList) o;
for(int i = 0; i < nodes.getLength(); i++)
System.out.println(nodes.item(i).getNodeValue());
