How to use getElementsByTagName to retrieve an array of elements from a XML file.

works perfectly. here is the new implementation...


 public static Coverage[] getFieldValues(Context cxt)

        {
          List<Coverage> dataContainer = new ArrayList<Coverage>();
          List<SystemElement> attributeList = null;
        Coverage[] allCoverage = null;
        Coverage instCoverageObj = null;  

        NodeList rootElement = null;
        if (cxt != null) {
              try{
                    Document document = cxt.getPersistenceEngine().getDocument();
                    rootElement = document.getElementsByTagName("Coverage");
                    int totalCoverages = rootElement.getLength();
                    Node baseElement = rootElement.item(0);              
                                           
                    for(int s=0; s < totalCoverages ; s++){
                          //////////////////////////////////////////////////////////////////
