上周末的时候，朋友约好去KTV，鉴于我这种不怎么听歌的孩子伤不起啊，灵机一动就把我的酷狗歌单导出来了，XML文件嘛，内容太多，我只想要歌名足已。于是写了一个java去输出歌名。
public void output(String filePath) throws FileNotFoundException{Scanner scanner=new Scanner(new File(filePath));String str=null;while(scanner.hasNextLine()){str=scanner.nextLine();if(str.indexOf("FileName")>0){System.out.println(str.substring(str.indexOf(">")+1, str.lastIndexOf("<")));}}scanner.close();}
<File><MediaFileType>0</MediaFileType><FileName>周杰伦 - 爱在西元前.mp3</FileName><FilePath>D:\music\</FilePath><FileSize>5623610</FileSize><Duration>234292</Duration><Hash>0589341ba15528a4c63e36c49a3c0e45</Hash><Lyric>E:\KuGou\Lyric\周杰伦 - 爱在西元前-0589341ba15528a4c63e36c49a3c0e45.krc</Lyric><Bitrate>192004</Bitrate><MandatoryBitrate>0</MandatoryBitrate></File>
public void output(String filePath) throws FileNotFoundException{Scanner scanner=new Scanner(new File(filePath),"UTF-8");//Always explicitly pass a charset when working with textString str=null;while(scanner.hasNextLine()){str=scanner.nextLine();if(str.indexOf("FileName")>0)System.out.println(str.substring(str.indexOf(">")+1, str.lastIndexOf("<")));}//It‘s better to check IOException when working with Scanner(PS:find UnmappableCharacterException took me more time,finally by debug to found )IOException ioException = scanner.ioException();if (ioException != null) {ioException.printStackTrace();}scanner.close();}
