解析XML时，org.apache.harmony.xml.ExpatParser$ParseException: At line 1, column 449: not well-forme

最近两天看mars老师的mp3播放器，一步一步跟着老师敲的代码，结果运行起来，解析xml时总是报错，表面上看程序执行到某一行不在执行：如下：

private List<Mp3Info> parse(String xmlStr){

SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();

List<Mp3Info> infos = new ArrayList<Mp3Info>();

try{

XMLReader xmlReader = saxParserFactory.newSAXParser().getXMLReader();

System.out.println("--------------2");

Mp3ListContentHandler mp3ListContentHandler = new Mp3ListContentHandler(infos);

System.out.println("--------------3");

xmlReader.setContentHandler(mp3ListContentHandler);

System.out.println("--------------4");

xmlReader.parse(new InputSource(new StringReader(xmlStr)));//这部开始错

System.out.println("--------------5");

for (Iterator<Mp3Info> iterator = infos.iterator(); iterator.hasNext();) {

Mp3Info mp3Info = (Mp3Info) iterator.next();

System.out.println("--------------6");

System.out.println(mp3Info);

}

catch(Exception e){

e.printStackTrace();

}

return infos;

}

看日志便是标题所示的错误：

org.apache.harmony.xml.ExpatParser$ParseException: At line 1, column 449: not well-formed

在网上查的时候发现了另外一个网友的一篇文章，遭遇我和类似，这是链接

在日志上有这样一处：

在这里，第三段的只开始到了“---startElement and tagName is mp3.name”这里，因此感觉是XML文件出错了，而受上面一篇文章的提示，就应该是XML的问题，上面一篇文章也是说sb的问题，也就是XML的流中出现的问题。基本上这两个问题是一个类型的。后来发现XML文件出错，把<mp3.name>Jay Sean-Maybe.mp3</mp3.name>写成了<mp3.name>Jay Sean-Maybe.mp3</name>

菜鸟一个，大家勿笑
