在Java中从UML活动图的XML文件创建中间图

Question

我为UML活动图生成了XML。 我想为XML生成树形结构，以便找到可能的过渡路径。 尝试使用DOMXML java解析器，但没有结果。 我需要将活动分组为节点，将过渡分组为边缘。 还附加了XML文件。 在此处输入图片说明，请帮助

Java代码

    public class DomXMLParser {

public static void main(String[] args)  throws ParserConfigurationException, SAXException, 
IOException, XPathExpressionException {
//DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
try {
    File fXmlFile = new File("C:/Projekte/activity.xml");
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    dbFactory.setNamespaceAware(true);
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
    Document doc = dBuilder.parse(fXmlFile);

    XPathFactory factory = XPathFactory.newInstance();
    XPath xpath = factory.newXPath();
    javax.xml.xpath.XPathExpression expr 
     = xpath.compile("//xmi:XMI[xmi:type ='uml:Activity']/name/text()");

    Object result = expr.evaluate(doc, XPathConstants.NODESET);
    NodeList nodes = (NodeList) result;
    for (int i = 0; i < nodes.getLength(); i++) {
        System.out.println(nodes.item(i).getNodeValue()); 
    }

Answer 1

Eclipse Modeling Framework（EMF）设计用于读取UML模型。 我编写代码以使用EMF读取UML类图 。 您可以在Enterprise Architect中设计模型，以便导出为UMl模型或在基于EMF的 纸莎草纸中进行设计
