dom4j解析XML文件

XML文件数据：

package com.test;

import java.io.File;
import java.util.Iterator;
import java.util.List;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public class ReadXML {
	public static void main(String[] args) {
		ReadXML xml=new ReadXML();
		try {
			xml.readXMLfile("D:\\city.xml");
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	public void readXMLfile(String filePath) throws Exception{
		File xmlFile=new File(filePath);
		SAXReader reader=new SAXReader();    
		Document xmlDoc=reader.read(xmlFile);    // Read xml stream
	    Element root=xmlDoc.getRootElement();    //Get the root node  of XML File
	    int j=0;
	    List listRowSet=xmlDoc.selectNodes("//country[1]//area//city");
	    for(Iterator i=listRowSet.iterator();i.hasNext();){
	     Element ele=(Element)i.next();
	     System.out.println("Test   "+ele.getName());
	     j++;
	    }
	}
}
