Question

Hi i want to parse XML and display list based on selection of user

my xml is looking like this

below is my code

      try {
            XMLParser parser = new XMLParser();
            Document doc = parser.getDomElement(xml); // getting DOM element
            NodeList n1 = doc.getElementsByTagName("company");

            // looping through all item nodes <item>
            for (int i = 0; i < n1.getLength(); i++) {
                // creating new HashMap
                Element e = (Element) n1.item(i);

                System.out.println("name node "+parser.getValue(e, "name"));
            }

by this way i am getting the output like

  Company ABC
  Company XYZ

of Companies list

but
i would write code like

        NodeList n1 = doc.getElementsByTagName("province"); 
        // looping through all item nodes <item>
            for (int i = 0; i < n1.getLength(); i++) {
                // creating new HashMap
                Element e = (Element) n1.item(i);

                System.out.println("name node "+parser.getValue(e, "name"));
            }

i am getting list of province name

   Alberta
   Ontario
   New York
   Florida

but it should work like this

when i select Company ABC

only two provision list should display

       Alberta
       Ontario

not should all display can any body help me how to rewrite my code

This should do it:

        XMLParser parser = new XMLParser();
        Document doc = parser.getDomElement(xml); // getting DOM element
        NodeList n1 = doc.getElementsByTagName("company");

        // looping through all item nodes <item>
        for (int i = 0; i < n1.getLength(); i++) {
            Element e = (Element) n1.item(i);
            System.out.println("name node "  +parser.getValue(e, "name"));
            NodeList children = e.getChildNodes();
            for (int j = 0; j < children.getLength(); j++) {
                 Node child = children.item(j);
                 if (child.getNodeName().equalsIgnoreCase("province")) {
                      System.out.println("name node " + parser.getValue((Element)child, "name"));
                 }
            }
        }
