Parse an RSS feed in Android

Android : how to parse THIS XML PARSE I would like to parse a RSS feed. My question is how can I parse all tags between the <item> and </item> tags.

  <channel>
 <title>Pub post</title>
 <atom:link href="http://abishtpub.wordpress.com/feed/" rel="self"              
 type="application/rss+xml"/>
 <link>http://abishtpub.wordpress.com</link>
  <description>A fine WordPress.com site</description>

  <item>
    <title>multi-content</title>

      <media:content url="http://1.gravatar.com/avatar/afb466de71a710f1e901250488e9ebd6? s=96&d=identicon&r=G" medium="image">
      <media:title type="html">abisht</media:title>
          </media:content>
      <media:content url="http://abishtpub.files.wordpress.com/2014/06/modern-medicine.jpg?w=300" medium="image">
      <media:title type="html">modern-medicine</media:title>
          </media:content>
      <media:content url="http://abishtpub.files.wordpress.com/2014/06/frisky_nursing_home.jpg?w=300" medium="image">
      <media:title type="html">frisky_nursing_home</media:title>
          </media:content>
   </item>

This is the code am using to parse the value.

NOTE: But am getting only one <media:content> value My Question is How to get All <media:content> values in all <items> tags.

   private String readItem(XmlPullParser parser)    throws XmlPullParserException, IOException {
            RSSItem rssItem = new RSSItem();
            ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();
            String result = "";// new SpannedString("");
            parser.require(XmlPullParser.START_TAG, null, "item");              

            while (parser.next()!= XmlPullParser.END_TAG) {
                if (parser.getEventType() != XmlPullParser.START_TAG) {
                    continue;
                }
                String name = parser.getName();
                Log.d("debug","item:name:"+name);
                if (name.equals("title")) {
                    rssItem.title = readTitle(parser);
                }else if(name.equals("link")){                      
                    rssItem.link = readlink(parser);
                } else if (name.equals("media:content")) {
                    result = readMedia(parser);
                }  

            }
            listData.add(rssItem);
            return result;
        }

I just tried the url posted under one of my posts.

Here's the code to parse

 XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
            factory.setNamespaceAware(false);
            XmlPullParser xpp = factory.newPullParser();
            InputStream is = new ByteArrayInputStream(res.getBytes());
            xpp.setInput(is,null);
            // xpp.setInput(getInputStream(url), "UTF-8");

            boolean insideItem = false;

            // Returns the type of current event: START_TAG, END_TAG, etc..
            int eventType = xpp.getEventType();
            while (eventType != XmlPullParser.END_DOCUMENT) {
                if (eventType == XmlPullParser.START_TAG) {

                    if (xpp.getName().equalsIgnoreCase("item")) {
                        insideItem = true;
                    } else if (xpp.getName().equalsIgnoreCase("title")) {
                        if (insideItem)
                            Log.i("Title is",xpp.nextText()); 
                    } else if (xpp.getName().equalsIgnoreCase("link")) {
                        if (insideItem)
                            Log.i("Link is",xpp.nextText()); 
                    }
                    else if (xpp.getName().equalsIgnoreCase("comments")) {
                        if (insideItem)
                            Log.i("Comment is.",xpp.nextText());  
                    }
                    else if (xpp.getName().equalsIgnoreCase("pubDate")) {
                        if (insideItem)
                            Log.i("Publish Date is.",xpp.nextText());  
                    }
                    else if (xpp.getName().equalsIgnoreCase("media:content")) {
                        if (insideItem)
                            Log.i("Media Content url is.",xpp.getAttributeValue(null, "url"));  
                    }
                    else if (xpp.getName().equalsIgnoreCase("media:title")) {
                        if (insideItem)
                            Log.i("Media Content title.",xpp.nextText());  
                    }

                } else if (eventType == XmlPullParser.END_TAG && xpp.getName().equalsIgnoreCase("item")) {
                    insideItem = false;
                }

                eventType = xpp.next(); /// move to next element
            }

The log

Note: I haven't check if all the tags are parsed. Do check it yourself.
