How to parse a Spring beans file using JDOM2

gistfile1.java

    private void run(File srcDir) throws IOException, JDOMException {
        List<String> mapperClassNames = new ArrayList<String>();

        SAXBuilder builder = new SAXBuilder();
        Document document = builder.build(new FileReader(new File(srcDir, "src/main/resources/dataAccessContext.xml")));
        Element rootElement = document.getRootElement();
        Namespace namespace = Namespace.getNamespace("http://www.springframework.org/schema/beans");
        List<Element> beans = rootElement.getChildren("bean", namespace);
        for (Element e : beans) {
            List<Element> property = e.getChildren("property", namespace);
            for (Element p : property) {
                Attribute name = p.getAttribute("name");
                if (name != null) {
                    if (name.getValue().equals("mapperInterface")) {
                        mapperClassNames.add(p.getAttribute("value").getValue());
                    }
                }
            }
        }

        File daoProjectDir = new File(srcDir.getParentFile(), "dao");
        for (String mapperClassName : mapperClassNames) {
            String relativePath = String.format("src/main/java/%s.java", mapperClassName.replaceAll("\\.", "/"));
            File existingMapperFile = new File(srcDir, relativePath);
            assert existingMapperFile.exists();
            File destinationMapperFile = new File(daoProjectDir, relativePath);
            destinationMapperFile.getParentFile().mkdirs();
            System.out.println(destinationMapperFile);
        }
    }
