以下是一个 Java 工具类，用于解析以上 XML 文件：

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;

public class XmlParser {

    public static void main(String[] args) {
        try {
            File file = new File("example.xml");
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document doc = builder.parse(file);
            doc.getDocumentElement().normalize();
            NodeList nodeList = doc.getElementsByTagName("Ref");
            List<Repository> repositories = new ArrayList<>();
            for (int i = 0; i < nodeList.getLength(); i++) {
                Node node = nodeList.item(i);
                if (node.getNodeType() == Node.ELEMENT_NODE) {
                    Element element = (Element) node;
                    String uid = element.getAttribute("UID");
                    String name = element.getAttribute("Name");
                    String href = element.getAttribute("Href");
                    Repository repository = new Repository(uid, name, href);
                    repositories.add(repository);
                }
            }
            for (Repository repository : repositories) {
                System.out.println(repository);
            }
        } catch (ParserConfigurationException | SAXException | IOException e) {
            e.printStackTrace();
        }
    }

    private static class Repository {
        private String uid;
        private String name;
        private String href;

        public Repository(String uid, String name, String href) {
            this.uid = uid;
            this.name = name;
            this.href = href;
        }

        @Override
        public String toString() {
            return "Repository [uid=" + uid + ", name=" + name + ", href=" + href + "]";
        }
    }

}

这个工具类首先读取 XML 文件，然后使用 DOM 解析器解析 XML 文件，并将解析结果存储在 Repository 对象中。最后，将所有 Repository 对象打印出来。
