Image URL from RSS

I have an app that shows an RSS feed. I am able to get the item titles, dates, and links with no problems but I am trying to figure out how to get the thumbnail URL.

EDIT: I am getting URLs, but my array of URL strings is filled with only the first URL. It is just storing it 22 times in the array.

Here is the XML from the feed with the image URL:

<media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="http://kyfbnewsroom.com/wp-content/uploads/2012/09/Beltway-News-web-250x250.jpg" width="250" height="250"/>

Here is my code:

public void getDataFromFeed(){

        try {
            Feed = new URL(URLFeed);
            DocumentBuilderFactory dbf= DocumentBuilderFactory.newInstance();
            db = dbf.newDocumentBuilder();
            doc = db.parse(new InputSource(Feed.openStream()));
            doc.getDocumentElement().normalize();
            nodeList = doc.getElementsByTagName("item");

            title = new String[nodeList.getLength()];
            pubDate = new String[nodeList.getLength()];
            link = new String[nodeList.getLength()];
            thumb = new String[nodeList.getLength()];

            for(int i=0;i<nodeList.getLength();i++){
                Node node = nodeList.item(i);

                Element fstElmnt = (Element) node;

                NodeList titleList = fstElmnt.getElementsByTagName("title");
                Element titleElement = (Element) titleList.item(0);
                titleList = titleElement.getChildNodes();
                title[i] = ((Node) titleList.item(0)).getNodeValue();

                NodeList pubDateList = fstElmnt.getElementsByTagName("pubDate");
                Element pubDateElement = (Element) pubDateList.item(0);
                pubDateList = pubDateElement.getChildNodes();
                pubDate[i] = ((Node) pubDateList.item(0)).getNodeValue();
                // chops off the " +0000" on date
                pubDate[i] = pubDate[i].substring(0, pubDate[i].length()-14);

                NodeList thumbList = doc.getDocumentElement().getElementsByTagName("media:thumbnail");
                Element thumbElement = (Element)thumbList.item(0);
                String thumbURL = thumbElement.getAttribute("url");
                thumb[i] = thumbURL;

                NodeList linkList = fstElmnt.getElementsByTagName("link");
                Element linkElement = (Element) linkList.item(0);
                linkList = linkElement.getChildNodes();
                link[i] = ((Node) linkList.item(0)).getNodeValue();
            }

        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }catch (ParserConfigurationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (SAXException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

if you're using org.w3c.dom do this:

NodeList nodes = doc.getDocumentElement().getElementsByTagNameNS("media", "thumbnail");
// if you expect there to possibly be more than one use a loop or whatever
Element elm = (Element) nodes.item(0); 
String url = elm.getAttribute("url");
