java利用jdom解析xml文件

说明：这只是一个简单的利用jdom解析xml文件的例子，读者可以下载附件的xml样例文件

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

import org.jdom.*;
import org.jdom.input.SAXBuilder;
import org.jdom.xpath.XPath;

public class ReadXml {

 public static void main(String[] args) {
      readXML();
 }
 
 private static void readXML(){

     //创建一个
     SAXBuilder builder=new SAXBuilder();
     try {

          //获取xml文件
          Document doc=builder.build(new File("data.xml"));
          

          //取得xml文件的根节点

          Element rootElt=(Element)doc.getRootElement();
          List eltList=XPath.selectNodes(rootElt,"//artist/catalog");
          Iterator iter=eltList.iterator(); 
          while(iter.hasNext()){
             Element catalog=(Element)iter.next();
             System.out.println("catalog_name:"+catalog.getChild("name").getText());
             System.out.println("alias:"+catalog.getChild("alias").getText());
    
             List items=catalog.getChildren("item");
             if(items!=null){
                  readCatalogItemAndMaterial(items);
              }
    
             List materials=catalog.getChildren("material");
            if(materials!=null){
                readCatalogItemAndMaterial(materials);
             }
     }
     } catch (JDOMException e) {
            e.printStackTrace();
      } catch (IOException e) {
            e.printStackTrace();
     }
 }
 
 private static void readCatalogItemAndMaterial(List list){
      Iterator iter=list.iterator();
      while(iter.hasNext()){
           Element elt=(Element)iter.next();
           System.out.println(elt.getChild("name").getText());
      }
 }
}
