XML : Looking for a specific child in XML using java

I've been looking for the past few hours, and I can't find how to do it.

My XML file:

  <list>          <Company id="01">                  <Name>Atari</Name>                  <Founded>1972</Founded>                  <Consoles>                          2600                          5200                          7800                  </Consoles>          </Company>          <Company id="02">                  <Name>Sega</Name>                  <Founded>1960</Founded>                  <Consoles>                          Master System                          Megadrive                          Saturn                  </Consoles>          </Company>  </list>  

Basically, I want the code to find not only the name in one company block, but the name in any company block I wish, and be able to show it to other classes. So far, I've been able to show either or, but only by changing the code directly and not on the fly. The code I'm using:

      private static String getTextValue(String def, Element doc, String tag) {      String value = def;      NodeList nl;      nl = doc.getElementsByTagName(tag);      if (nl.getLength() > 0 && nl.item(0).hasChildNodes()) {          value = nl.item(0).getFirstChild().getNodeValue();      }      if(value==null) value = " ";      return value;  }    public static boolean readXML(String xml) {      rolev = new ArrayList<String>();      Document dom;      // Make an  instance of the DocumentBuilderFactory      DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();      try {          // use the factory to take an instance of the document builder          DocumentBuilder db = dbf.newDocumentBuilder();          // parse using the builder to get the DOM mapping of the              // XML file          dom = db.parse(xml);            Element doc = dom.getDocumentElement();            role1 = getTextValue(role1, doc, "Name");          if (getRole1() != null) {              if (!getRole1().isEmpty())                  rolev.add(getRole1());          }          role2 = getTextValue(role2, doc, "Founded");          if (role2 != null) {              if (!role2.isEmpty())                  rolev.add(role2);          }          role3 = getTextValue(role3, doc, "Consoles");          if (role3 != null) {              if (!role3.isEmpty())                  rolev.add(role3);          }          role4 = getTextValue(role4, doc, "Name");          if ( role4 != null) {             if (!role4.isEmpty())                  rolev.add(role4);          }          return true;        } catch (ParserConfigurationException pce) {          System.out.println(pce.getMessage());      } catch (SAXException se) {          System.out.println(se.getMessage());      } catch (IOException ioe) {          System.err.println(ioe.getMessage());      }        return false;  }    

I used a lot of different methods, some searched up and some made on my own, but this one is the closest I can get to working for what I need. I need to be able to have the place it's looking change on the fly though.
