I'm trying to read xml file, ex :

<entry>
    <title>FEED TITLE</title>
    <id>5467sdad98787ad3149878sasda</id>
    <tempi type="application/xml">
      <conento xmlns="http://mydomainname.com/xsd/radiofeed.xsd" madeIn="USA" />
    </tempi>
</entry>

Here is the code I have so far :

    public void parseXML(String xml) {

      try {
      InputStream inputStream = new ByteArrayInputStream(xml.getBytes());
      DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
      DocumentBuilder db = dbf.newDocumentBuilder();
      Document doc = db.parse(inputStream);
      doc.getDocumentElement().normalize();
      System.out.println("Root element " + doc.getDocumentElement().getNodeName());
      NodeList nodeLst = doc.getElementsByTagName("entry");
      System.out.println("Information of all entries");

      for (int s = 0; s < nodeLst.getLength(); s++) {

        Node fstNode = nodeLst.item(s);

        if (fstNode.getNodeType() == Node.ELEMENT_NODE) {

          Element fstElmnt = (Element) fstNode;

          NodeList title = fstElmnt.getElementsByTagName("title").item(0).getChildNodes();
          System.out.println("Title : "  + ((Node) title.item(0)).getNodeValue());

          NodeList id = fstElmnt.getElementsByTagName("id").item(0).getChildNodes();
          System.out.println("Id: " + ((Node) update.item(0)).getNodeValue());

          NodeList contento= fstElmnt.getElementsByTagName("tempi").item(0).getChildNodes();
          System.out.println("Contento : " + ((Node) content.item(0)).getFirstChild().getAttributes()); 
         // with this line above I'm having problems, I get null pointer exception
        }

      }
      } catch (Exception e) {
        e.printStackTrace();
      }
     }

How can I read/get, contento tag attributes? I'm using org.w3c.dom lib.
