我使用XML在java中创建应用程序。
XML -
<?xml version="1.0" encoding="UTF-8"?>
<songlist id="slist">
<song name="Club Can't Handle Me" path="E:/Google Chrome Downloads/club cant handle me.mp3" artist="Flo Rida feat. David Guetta" album="The Only One" />
<song name="Call It What You Want" artist="Foster the People" path="E:\Google Chrome Downloads\call it what you want.mp3" album="Torches" />
<song name="Break Your Heart (Remix) Ft. Ludacris" artist="Taio Cruz" path="E:\Google Chrome Downloads\Break your heart.mp3" album="Rockstarr" />
<song name="Burn It To The Ground" artist="Nickelback" path="E:\Google Chrome Downloads\Burn It To The Ground.mp3" album="Dark Horse" />
<song name="Levels" artist="Avicii" path="E:\Google Chroome Downloads\Avicii - Levels.mp3" album="" />
<song name="Beautiful" artist="Akon" path="E:\Google Chrome Downloads\Beautiful.mp3" album="http://www.urbanascor.com" />
<song name="Bumpy Ride" artist="" path="E:\Google Chrome Downloads\bumpy ride.mp3" album="" />
</songlist>
我试图获取子元素(歌曲)的属性,但我无法做到这一点。我正在使用JDOM。
Java代码 -
public class Opener extends WindowAdapter{
@Override public void windowOpened(WindowEvent e){
try{
SAXBuilder builder = new SAXBuilder();
File xmlFile = new File("E:/Yash programs/mp3/list.xml");
Document doc = (Document) builder.build(xmlFile);
Element rootNode = doc.getRootElement();
List l = rootNode.getChildren();
for(int i = 1;i<=l.size();i++){
listModel.addElement(l.get(i).toString());
}
}
catch (JDOMException ex) {
Logger.getLogger(MP3View.class.getName()).log(Level.SEVERE, null, ex);
}
catch(IOException io){
io.printStackTrace();
}
}
}
请帮帮我。我是初学者,对不起。
请以另一种方式建议我这样做。
由于
答案 0 :(得分:1)
List songElements = doc.getRootElement().getChildren("song");
for(int i = 1 ; i <= songElements.size() ; i++) {
Element songElement = (Element) songElements.get(i);
String name = songElement.getAttributeValue("name");
String path = songElement.getAttributeValue("path");
String album = songElement.getAttributeValue("album");
}
JDOM的集合是无类型的,因此您需要知道rootNode.getChildren
的返回值是List
的{{1}},或者在这种情况下,Node
。
