使用dom4j 读取上述XML内容：

在pom 加入 dom4j.jar  的依赖

<dependency>
      <groupId>dom4j</groupId>
      <artifactId>dom4j</artifactId>
      <version>1.6.1</version>
    </dependency>
           

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：
