Skip a child while parsing XML file

I'm using a XML parser in many activity and now I have a problem :

Here is my XML FILE

And I don't want all of the childs from the "stop" parent.

Because there are the same child in "stop" and in "departures" and I only want the data from "departures" child.

How can I do this with my code ?

    public void parseXML()
{
    try {
        URI url=null;
        url = new URI(Departs.passedCode);

        try {
            HttpClient client = new DefaultHttpClient();
            HttpResponse response = client.execute(new HttpGet(url));

            stream = response.getEntity().getContent();
        } catch (IOException e) {
            e.printStackTrace();
            publishProgress("Exception: " + e.toString());
        }

      DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
      dbf.setIgnoringComments(true);
      dbf.setIgnoringElementContentWhitespace(true);
      DocumentBuilder db = dbf.newDocumentBuilder();
      Document doc = db.parse(stream);
      doc.getDocumentElement().normalize();


      NodeList stopList = doc.getElementsByTagName("lineCode");

      String Name="";



      for (int i = 0; i < stopList.getLength(); i++)
      {
          Element elementStopCode = (Element)stopList.item(i);
          String strName = elementStopCode.getTextContent();
          Name = Name.concat("\n"+ strName);     
      }



      publishProgress(Name);

    }
  catch (Exception e) 
  {
    e.printStackTrace();
    publishProgress("Exception: " + e.toString());
  }

}

Thank you for your help
