Question

Hi im very new to webserices and xml parsing.I use http://www.mysamplecode.com/2011/11/android-parse-xml-file-example-using.html this link as my reference.
But i think in this link the xml is a simple one.How can i parse a complex xml like this one.Can any one suggest me a method to parse this. I want to read the values of < A >,< B >,< C >,< D > tags from each MenuEntry

        <Menu>
         <MenuEntries>

           <MenuEntry>
           <A>--AAAAA---</A>
           <B>--BBBB---</B>
           <MenuEntries/>
           <C>--CCCC---</C>
           <D>--DDDD---</D>
           </MenuEntry>

            <MenuEntry>
            <B>--BBBB---</B>
            <menuEntries/>
            <C>--CCCC---</C>
            <D>--DDDD---</D>
            </MenuEntry>

            <MenuEntry>
            <A>--AAAAA---</A>
            <B>--BBBB---</B>
             <MenuEntries>

                <MenuEntry>
                <A>--AAAAA---</A>
                <B>--BBBB---</B>
                <MenuEntries/>
                <C>--CCCC---</C>
                <D>--DDDD---</D>
                </MenuEntry>

                <MenuEntry>
                <A>--AAAAA---</A>
                <B>--BBBB---</B>
                <MenuEntries/>
                <C>--CCCC---</C>
                <D>--DDDD---</D>
                </MenuEntry>

             </MenuEntries>
           <C>--CCCC---</C>
           <D>--DDDD---</D>
             </MenuEntry>

        <MenuEntry>
        <B>--BBBB---</B>
        <MenuEntries/>
        <C>--CCCC---</C>
        <D>--DDDD---</D>
          </MenuEntry>

        <MenuEntry>
        <A>--AAAAA---</A>
        <B>--BBBB---</B>
        <MenuEntries>

            <MenuEntry>
            <A>--AAAAA---</A>
            <B>--BBBB---</B>
            <MenuEntries/>
            <C>--CCCC---</C>
            <D>--DDDD---</D>
            </MenuEntry>

        </MenuEntries>
        <C>--CCCC---</C>
        <D>--DDDD---</D>
          </MenuEntry>

        </MenuEntries>
        </Menu>

This is my xmlHandler class for parsing the xml

    public class ItemXMLHandler extends DefaultHandler {

        Boolean currentElement = false;
        String currentValue = "";
        Menu item = null;
         static ArrayList<Menu> menuList = new ArrayList<Menu>();

        public static ArrayList<Menu> getMenuListz() {

            Log.e("in getMenulist()", String.valueOf(menuList.size()));
            return menuList;
        }

        // Called when tag starts
        @Override
        public void startElement(String uri, String localName, String qName,
                Attributes attributes) throws SAXException {

            currentElement = true;
            currentValue = "";
            if (localName.equals("MenuEntry")) {
                //Log.e("menuENtry found ", "menuENtry found");
                item = new Menu();

            }

        }

        @Override
        public void endElement(String uri, String localName, String qName)
                throws SAXException {

            currentElement = false;

            /** set value */
            if (localName.equalsIgnoreCase("A")) {
                item.setA(currentValue);
            } else if (localName.equalsIgnoreCase("B")) {
                item.setB(Long.parseLong(currentValue));
            } else if (localName.equalsIgnoreCase("C")) {
                    item.setC(currentValue);
            } else if (localName.equalsIgnoreCase("menuEntry"))

                menuList.add(item);

        }

        // Called to get tag characters
        @Override
        public void characters(char[] ch, int start, int length)
                throws SAXException {

            if (currentElement) {
                currentValue = currentValue + new String(ch, start, length);
            }

        }

    }

This is my java class for Menu

    public Class Menu{
        private long B;
        private String A;
        private String C;

        public long getB() {
            return B;
        }
        public void setB(long B){
            this.B = B;
        }
        public String getA() {
            return A
        }
        public void setA(String A){
            this.A = A
        }
        public String getC() {
            return C
        }
        public void setC(String C) {
            this.C = C;
        }
    }

Im getting duplications and null values.I know my coding could be wrong can any one help me with a reply or any useful links for parsing this kind of complex xml ( for me its complex 🙂 )
