可以使用Java自带的DOM解析器来解析XML文件。以下是一个示例工具类：

import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;

public class XMLParser {
    public static void parse(String filePath) {
        try {
            File file = new File(filePath);
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document document = builder.parse(file);
            
            // 获取根节点
            Element root = document.getDocumentElement();
            // 获取所有子节点
            NodeList nodeList = root.getElementsByTagName("Ref");
            for (int i = 0; i < nodeList.getLength(); i++) {
                Element element = (Element)nodeList.item(i);
                String uid = element.getAttribute("UID");
                String name = element.getAttribute("Name");
                String href = element.getAttribute("Href");
                String type = element.getAttribute("Type");
                System.out.println("UID: " + uid + ", Name: " + name + ", Href: " + href + ", Type: " + type);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

调用该工具类的静态方法`parse`，传入XML文件的路径即可解析XML文件并输出所有`Ref`节点的属性。例如：

XMLParser.parse("example.xml");

输出结果为：
