Convert xml file to a 2D list - Urgent!!!

Question

I have a xml file like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE map SYSTEM "map.dtd">
<map width="5" height="3" goal="6" name="Hallways of Dooom">
     <random-item type='lantern' amount='5' />
     <random-item type='health' amount='10' />
     <tile x="1" y="0" type="floor">
          <renderhint>floor:wood</renderhint>
     </tile>
     <tile x="0" y="1" type="floor" />
     <tile x="1" y="1" type="floor" startlocation="1" />
     <tile x="2" y="0" type="wall" />
     <tile x="3" y="0" type="wall" />
     <tile x="3" y="1" type="floor">
          <item type="treasure">Bar of Silver</item>
          <renderhint>floor:stone,blood</renderhint>
     </tile>
</map>and i want to convert it to a 2D list, with the x-value of the list is the width of the map and the y-value of the list is the height of the map. The x and y value in the tile indicates the position of the point.
i have already parse the xml file to java using:
public class parsexml
         public static void main(String[] args)
          DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          factory.setValidating(true);
          factory.setIgnoringElementContentWhitespace(true);
          try {
               DocumentBuilder parser = factory.newDocumentBuilder();
               Document doc = parser.parse(new File("hallways.xml"));
               System.out.println("XML file parsed.");
          } catch (ParserConfigurationException e) {
               e.printStackTrace();
          } catch (SAXException e) {
               e.printStackTrace();
          } catch (IOException e) {
               e.printStackTrace();
}Can anyone give me any hint on what to do next. Thank you very much.
