title: XMLPullParser with prefix and self closing tag
body: <p>I have an issue on XML parsing with XMLPullParser on Android since few days. I'm trying to parse this :</p>
  
  <pre><code>&lt;media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="http://3.bp.blogspot.com/-6JMmPoQTJOc/UoYaJT9Ih9I/AAAAAAAAE7I/mnO_69i8rAs/s72-c/ANTICIPA-Logo.png" height="72" width="72"/&gt;
  </code></pre>
  
  <p>I want to get the image URL, which I successfully do. However, I am not able to detect the END_TAG, and I don't know how to do it.</p>
  
  <p>Here is my parsing code :</p>
  
  <pre><code>    private String readImage(XmlPullParser parser) throws IOException, XmlPullParserException {
          parser.require(XmlPullParser.START_TAG, ns, "media:thumbnail");
          String imageLink = parser.getAttributeValue(null, "url");
          parser.require(XmlPullParser.END_TAG, ns, "thumbnail"); // THIS LINE HAS A PROBLEM
          Log.d("DEBUG", imageLink);
          return imageLink;
      }
  </code></pre>
  
  <p>I tried to give "thumbnail", "media:thumbnail", "/", nothing seems to work. Do you have an idea ?</p>
