小弟android新手，请教一个xml解析的问题
问题：xmlReader.parse(new InputSource(new StringReader(xmlStr))); 这行代码为什么执行不了？
理由：System.out.println("xml------------");放在上行代码前能打印出来，放到之后就打印不出来，并且log里面提醒的也是这行代码！

全部代码如下：
package your.napo;

import java.io.StringReader;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import javax.xml.parsers.SAXParserFactory;

import napo.download.HttpDownload;
import napo.model.Mp3Info;
import napo.xml.Mp3ListContentHandler;

import org.xml.sax.InputSource;
import org.xml.sax.XMLReader;

import android.app.ListActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class Mp3player extends ListActivity {
/** Called when the activity is first created. */

private static final int UPDATE = 1;
private static final int ABOUT = 2;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
menu.add(0, UPDATE, 1, R.string.mp3list_update);
menu.add(0, ABOUT, 2, R.string.mp3list_about);
return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId() == UPDATE) {
String xml = downloadXML("http://192.168.1.2:8080/mp3/resources.xml");
parse(xml);

}
else if(item.getItemId() == ABOUT) {

}
return super.onOptionsItemSelected(item);
}

private String downloadXML(String urlStr) {
HttpDownload httpDownload = new HttpDownload();
String result = httpDownload.download(urlStr);
return result;
}

private List<Mp3Info> parse(String xmlStr) {
SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
List<Mp3Info> infos = new ArrayList<Mp3Info>();
try {
XMLReader xmlReader = saxParserFactory.newSAXParser().getXMLReader();
Mp3ListContentHandler mp3ListContentHandler = new Mp3ListContentHandler(infos);
xmlReader.setContentHandler(mp3ListContentHandler);
System.out.println("xml------------");
xmlReader.parse(new InputSource(new StringReader(xmlStr)));

for (Iterator iterator = infos.iterator(); iterator.hasNext();) {
Mp3Info mp3Info = (Mp3Info) iterator.next();

System.out.println(mp3Info);
}
} catch(Exception e) {
e.printStackTrace();
}
return infos;
}
}



Log如下：

[解决办法]
mismatched tag

XML文件缺少标识，打开这个文件看一下是不是缺少了结束标记之类的。
[解决办法]
不是定义了Mp3ListContentHandler 么，进去看看里面解析的过程中是到哪儿错了。
[解决办法]
xml文件错误了，一个字母之错
