dom4j简单读写xml文件

生成xml文件 XMLDom4jAtWrite .java

import java.io.FileWriter;
import java.io.IOException;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;

public class XMLDom4jAtWrite {
	public static void main(String[] args) throws IOException {
		Document doc = DocumentHelper.createDocument();
		//节点
		Element elements = doc.addElement("users");
		Element username = elements.addElement("username");
		Element pass = elements.addElement("password");
		//属性
		username.addAttribute("type","button");
		
		username.setText("110");
		pass.setText("password");
		
		//生成-加上xml格式
		XMLWriter xmlWriter = new XMLWriter(new FileWriter("c:/m.xml"),OutputFormat.createPrettyPrint());
		xmlWriter.write(doc);
		xmlWriter.close();
		System.out.println("end-");
	}
}

读取xml文件 XMLDom4jAtRead .java

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

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

public class XMLDom4jAtRead {
	public static void main(String[] args) {

		SAXReader saxReader = new SAXReader();
		Document document = null;
		try {
			document = saxReader.read(new FileReader(new File("c:/mail.xml")));
		} catch (Exception e) {
			e.printStackTrace();
			System.out.println("error 403");
		}

		Element listElement = document.getRootElement();
		Iterator<Element> elem = listElement.elementIterator();

		while (elem.hasNext()) {
			Element e = elem.next();
			
			Iterator<Element> elem2 = e.elementIterator();
			while(elem2.hasNext()){
				Element e2 = elem2.next();
				System.out.print(e2.getName()+":"+e2.getText());
			}	
		}
		System.out.println("end-");
	}
}
