java解析xml文件并输出

使用java解析xml文件，通过dom4j，代码运行前需先导入dom4j架包。

ParseXml类代码如下：

import java.io.File;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public class ParseXml {
	public void read() throws Exception {
		SAXReader reader = new SAXReader();
		Document document = reader.read(new File("src/test.xml"));
		Element root = document.getRootElement();
		// 将解析出来的allresource下的resourceitem放在list中
		@SuppressWarnings("rawtypes")
		List list = root.elements("resourceitem");
		// 创建source存放每一个resourceitem中资源
		List<XmlBean> source = new ArrayList<XmlBean>();
		// 将resourceitem中的各项解析出来，通过XmlBean存放到source中
		for (@SuppressWarnings("rawtypes")
		Iterator i = list.iterator(); i.hasNext();) {
			Element resourceitem = (Element) i.next();
			String id = resourceitem.element("id").getText();
			String title = resourceitem.element("title").getText();
			String keywords = resourceitem.element("keywords").getText();
			String kind = resourceitem.element("kind").getText();
			String describe = resourceitem.element("describe").getText();
			String date = resourceitem.element("date").getText();
			String url = resourceitem.element("url").getText();
			String author = resourceitem.element("author").getText();
			String publisher = resourceitem.element("publisher").getText();
			XmlBean bean = new XmlBean();
			bean.setId(id);
			bean.setTitle(title);
			bean.setKeywords(keywords);
			bean.setKind(kind);
			bean.setDescribe(describe);
			bean.setDate(date);
			bean.setUrl(url);
			bean.setAuthor(author);
			bean.setPublisher(publisher);
			source.add(bean);
		}
		//这里只选两个解析出的结果进行输出
		for (int i = 0; i < source.size(); i++) {
			System.out.println("date数据为："+source.get(i).getDate());
			//System.out.println("url数据为："+source.get(i).getUrl());
		}	
		for (int i = 0; i < source.size(); i++) {
			//System.out.println("date数据为："+source.get(i).getDate());
			System.out.println("url数据为："+source.get(i).getUrl());
		}	
	}
	
	//主函数调用上面read()方法
	public static void main(String[] args){ 
		try { 
		new ParseXml().read(); 
		} catch (Exception e){ 
		    e.printStackTrace(); 
		} 
		} 
}

XmlBean类代码如下：

public class XmlBean {  
    private String id;  
    private String title;  
    private String keywords;  
    private String kind;  
    private String describe;  
    private String date;  
    private String url;  
    private String author;  
    public String getKeywords() {  
        return keywords;  
    }  
  
    public void setKeywords(String keywords) {  
        this.keywords = keywords;  
    }  
  
    public String getKind() {  
        return kind;  
    }  
  
    public void setKind(String kind) {  
        this.kind = kind;  
    }  
  
    public String getDescribe() {  
        return describe;  
    }  
  
    public void setDescribe(String describe) {  
        this.describe = describe;  
    }  
  
    public String getDate() {  
        return date;  
    }  
  
    public void setDate(String date) {  
        this.date = date;  
    }  
  
    public String getUrl() {  
        return url;  
    }  
  
    public void setUrl(String url) {  
        this.url = url;  
    }  
  
    public String getAuthor() {  
        return author;  
    }  
  
    public void setAuthor(String author) {  
        this.author = author;  
    }  
  
    public String getPublisher() {  
        return publisher;  
    }  
  
    public void setPublisher(String publisher) {  
        this.publisher = publisher;  
    }  
  
    private String publisher;  
  
    public String getId() {  
        return id;  
    }  
  
    public void setId(String id) {  
        this.id = id;  
    }  
  
    public String getTitle() {  
        return title;  
    }  
  
    public void setTitle(String title) {  
        this.title = title;  
    }  
}  

test.xml文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>  
  
<allresource host="192.168.16.111" remote="192.168.16.111">   
  <resourcenum>499</resourcenum>    
  <resourceitem>   
    <id>2</id>    
    <title>《实数》复习d.doc</title>    
    <keywords>实数复习，期中复习</keywords>    
    <kind>doc</kind>    
    <describe>期中复习训练题</describe>    
    <date>2008-6-18 20:50:01</date>

    <author>胡克林</author>    
    <publisher>历城二中</publisher>   
  </resourceitem>    
  <resourceitem>   
    <id>3</id>    
    <title>《轴对称图形》教学设计</title>    
    <keywords>轴对称图形，平面几何图形</keywords>    
    <kind>doc</kind>    
    <describe>认识轴对称图形，知道轴对称图形的含义，能够找出轴对称图形的对称轴</describe>    
    <date>2008-6-18 20:55:10</date>    
    <url>http://192.168.16.111:8080/resources/《轴对称图形》教学设计.doc</url>    
    <author>胡克林</author>    
    <publisher>历城二中</publisher>   
  </resourceitem>    
  </allresource>

运行结果（我只让他输出了部分值）如下图所示：
