xml 文件：

<?xml version="1.0" encoding="utf-8" ?>

使用dom4j 读取上述XML内容：

在pom 加入 dom4j.jar  的依赖

Java代码：

import org.dom4j.Document;
    import org.dom4j.DocumentException;
    import org.dom4j.Element;
    import org.dom4j.io.SAXReader;
    
    import java.io.File;
    import java.util.Iterator;
    
    /**
     * 解析XML文件
     */
    public class XmlReader {
    
        public static void main(String[] args) {
            String xmlFile = "C:\\Users\\thinkpad\\Desktop\\福建省各市经纬度.xml";
            readXml(xmlFile);
        }
    
        public static void readXml(String xmlPath){
            File file = new File(xmlPath);
            SAXReader reader = new SAXReader();
            try {
                Document document = reader.read(file);
                Element root = document.getRootElement();
                Element foo;
                Iterator i = root.elementIterator("e");
                while (i.hasNext()){
                    foo = (Element)i.next();
                    System.out.println("CLASS:"+foo.elementText("CLASS"));
                    System.out.println("GBCODE:"+foo.elementText("GBCODE"));
                    System.out.println("ID:"+foo.elementText("ID"));
                    System.out.println("LAT:"+foo.elementText("LAT"));
                    System.out.println("LON:"+foo.elementText("LON"));
                    System.out.println("NAME:"+foo.elementText("NAME"));
                    System.out.println("==============================\n");
                }
            } catch (DocumentException e) {
                e.printStackTrace();
            }
        }
    }

运行结果：
