Xml Parser unerwarteten Token Fehler Position: TEXT @ 1: 2 in java.io.StringReader

Question

Das Problem ist, wenn ich die XML von der ursprünglichen Verbindung zum Beispiel analysieren (Ich posten nicht den ursprünglichen Link aus Sicherheitsgründen)http://example.com/ss.svc/APIabc?A=10&Key=XXXXX&From=19&To=221&Date=19-Apr-2016 dann Listview nicht aufgefüllt und die die logcat sagt Fehler dieses

LogCat fehler-

Unexpected token (position:TEXT @1:2 in java.io.StringReader@4255df00)

aber wenn die gleiche XML wird dann mit .php endet mit dem Link auf einen anderen Server Link setzen für Beispiel dieseshttp://www.example.in/exapmle/sub.php t zeigt die analysierten Daten zur Listenansicht.

Say my XML-Format wie dieses

ist

<APIabc 
    xmlns="http://exapmle.org/"> 
    <APIabcd 
     xmlns:a="http://ac.ssc.org/2014/21/abfaggkk" 
     xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> 
     <Route> 
      <Time>2016-04-13 06:11:00 AM</Time> 
      <Avail>xyz</Avail> 
      <thumb_url>http://api.androidhive.info/music/images/adele.png</thumb_url> 
      <BusLabel/> 
     </Route> 
    </APIabcd> 
</APIabc> 

CustomizedListView.java

public class CustomizedListView extends Activity { 
     // All static variables 
     static final String URL = "http://example.com/ss.svc/APIabc?A=10&Key=XXXXX&From=19&To=221&Date=19-Apr-2016"; 
     // XML node keys 
     static final String KEY_SONG = "Route"; // parent node 
    static final String KEY_ID = "Avail"; 
    static final String KEY_TITLE = "Avail"; 
    static final String KEY_ARTIST = "Avail"; 
    static final String KEY_ARTIST2 = "Avail"; 
    static final String KEY_DURATION = "Avail"; 
    static final String KEY_THUMB_URL = "thumb_url"; 

     ListView list; 
     LazyAdapter adapter; 

     @Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.main); 

      ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>(); 

      XMLParser parser = new XMLParser(); 
      String xml = parser.getXmlFromUrl(URL); // getting XML from URL 
      Document doc = parser.getDomElement(xml); // getting DOM element 

      NodeList nl = doc.getElementsByTagName(KEY_SONG); 
      // looping through all song nodes <song> 
      for (int i = 0; i < nl.getLength(); i++) { 
       // creating new HashMap 
       HashMap&lt;String, String&gt; map = new HashMap&lt;String, String&gt;(); 
       Element e = (Element) nl.item(i); 
       // adding each child node to HashMap key =&gt; value 
       map.put(KEY_ID, parser.getValue(e, KEY_ID)); 
       map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE)); 
       map.put(KEY_ARTIST, parser.getValue(e, KEY_ARTIST)); 
       map.put(KEY_DURATION, parser.getValue(e, KEY_DURATION)); 
       map.put(KEY_THUMB_URL, parser.getValue(e, KEY_THUMB_URL)); 

       // adding HashList to ArrayList 
       songsList.add(map); 
      } 

      list=(ListView)findViewById(R.id.list); 

      // Getting adapter by passing xml data ArrayList 
      adapter=new LazyAdapter(this, songsList); 
      list.setAdapter(adapter); 

      // Click event for single list row 
      list.setOnItemClickListener(new OnItemClickListener() { 

       @Override 
       public void onItemClick(AdapterView&lt;?&gt; parent, View view, 
         int position, long id) { 

       } 
      }); 
     } 
    } 

Wie logcat Fehler sagt com.example.androidhive.CustomizedListView.onCreate (CustomizedListView. java: 48) so die Linie 48 in Code

NodeList nl = doc.getElementsByTagName(KEY_SONG); 

Answer 1

Gelöst es durch meine self.The Weise gelöst i es ist wie- ich aus dem Code aus den folgenden Zeilen kommentiert

// InputSource is = new InputSource(); 
    // is.setCharacterStream(new StringReader(xml)); 
    doc = db.parse(is); 

und übergeben Sie die URL direkt auf diese Linie

doc = db.parse("http://yourURL.xml");
