Прочитать изображение url из xml в android

Question

Я хочу прочитать изображение с этого URL-адреса.

<?xml version="1.0" encoding="UTF-8"?> 
<rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"> 

    <channel> 

    <title>podCast411</title> 
    <description>The 411 on podCasts, podCasters and podcasting</description> 
    <link>http://www.podcast411.com</link> 
    .. 
    .. 
    <itunes:explicit>No</itunes:explicit> 

    <itunes:image href="http://www.podcast411.com/img/411_itunes.jpg"/> 
    .. 
    </channel> 
</rss> 

Я могу прочитать название, описание из этой ленты, используя следующий код.

Node results = doc.getDocumentElement(); 
      Element docElement = doc.getDocumentElement(); 
      NodeList childNodes = docElement.getChildNodes(); 
      NodeList itemLinks = docElement.getElementsByTagName("item"); 
      Log.d("TAG", 
        "Response:" + results.getLastChild() + " " 
          + childNodes.getLength() + " " + itemLinks.getLength()); 


      for (int i = 0; i < itemLinks.getLength(); i++) { 
       Element el = (Element) itemLinks.item(i); 


       NodeList itemTitle = el.getElementsByTagName("title"); 
       Element itemFirst = (Element) itemTitle.item(0); 
       String nTitle = itemFirst.getFirstChild().getNodeValue(); 


       NodeList itemdesc = el.getElementsByTagName("description"); 
       Element itemFirstdesc = (Element) itemdesc.item(0); 
       String nDesc = stipHtml(itemFirstdesc.getFirstChild().getNodeValue()); 

} 
public String stipHtml(String html) { 
      return Html.fromHtml(html).toString(); 
     } 

Когда я пытаюсь сделать тот же код для чтения URL-адреса, он не работает. нижеприведенный код предназначен для чтения imade URL:

NodeList itemImage = el.getElementsByTagName("image"); 
       String imageUrl = null; 
       for(i=0;i< itemImage.getLength();i++) { 
        Log.d("TAG", "Length of item is "+ itemImage.getLength()); 
        Element itemFirstImage = (Element) itemImage.item(i); 
        NodeList url = itemFirstImage.getElementsByTagName("url"); 
        Element link = (Element) url.item(i); 
        imageUrl = stipHtml(link.getFirstChild().getNodeValue()); 
       } 

Что не так в моем коде?

Мой лог-код: он отображается для всего элемента.

пожалуйста, дайте мне какой-либо другой способ ее достижения.

try { 
      InputStream myxml = this.getApplicationContext().getAssets().open("production.xml"); 
      DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); 
      Document doc = db.parse(myxml); 
      doc.getDocumentElement().normalize(); 
      NodeList nodeList = doc.getElementsByTagName("channel"); 
      name = new TextView[nodeList.getLength()]; 

      for (int i = 0; i<nodeList.getLength(); i++) 
      { 
       Node node = nodeList.item(i);    
       Element fstElmnt = (Element) node; 
       NodeList toList = fstElmnt.getElementsByTagName("itunes:image"); 
       Element nameElement = (Element) toList.item(0); 
       toList = nameElement.getChildNodes();  
       String link = ((Node) toList.item(0)).getNodeValue(); 
       // link would be containing url of ur image   
      } 


      } catch (Exception e) { 
        System.out.println("XML Pasing Excpetion = " + e); 
      }
