Parse xml data into hashtable and displaying in listview?

I have a problem. I have multiple records that after SAX parsing from a xml file that needs to be inserted into the Hashtable and displayed in a listview. I am able to display the data in the listview but all it gives is the same data for all rows in the listview. I think it has something to do with either my coding for the hashtable or my SAX parsing.

This is the xml file I'm trying to retrieve data from online: http://spark.opac.tp.edu.sg/X?op=present&set_no=007584&set_entry=000000001,000000002,000000003,000000004,000000005&format=marc

Below is my handler where i place my data into the hashtable:

ArrayList<Hashtable<String,String>> list = new ArrayList<Hashtable<String,String>>();

Hashtable<String,String> data = new Hashtable<String,String>();

private final String MY_DEBUG_TAG = "Debugging~";

private Boolean in_record = false;
private Boolean in_author = false;
private Boolean in_format = false;
private Boolean in_title = false;
private Boolean in_callNumber = false;

private String format = "";
private String title = "";
private String author = "";
private String callNumber = "";

//private SearchList sList;

//public SearchList getListData() {
//  return this.sList;
//}

@Override
public void startDocument() throws SAXException {
 //       this.sList = new SearchList();
}

@Override
public void endDocument() throws SAXException {
        // Nothing to do
}

               }
       //add the hashtable into ArrayList        
       list.add(data);
}

Any suggestions guys?

I don't have time to read completly your code ...

But this is a simple example :

ListView myListView;
myListView = (ListView) findViewById(R.id.mylistview);
ArrayList<HashMap<String, String>> listItem = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map;

//load your data
String[][] items = database.getItems("Blog");

//check if the database was empty
if(items != null){
    for(int i = 0; i < items[0].length; i++) {
        map = new HashMap<String, String>();
        map.put("pubdate", items[2][0]);
        map.put("title", items[0][i]);
        map.put("description", items[1][i]);
        listItem.add(map);

    }

    //Creation of a SimpleAdapter to put items in your list (listitems) in your listview
    // You need to have a xml file called list_full_news_item with elements
    // called android:id="@+id/title" etc.
    SimpleAdapter mSimpleAdaptor = new SimpleAdapter (this.getBaseContext(), listItem, R.layout.list_full_news_item,
        new String[] {"pubdate", "title", "description"}, new int[] {R.id.itemPubdate, R.id.itemTitle, R.id.itemDescription});
   //Assign to the listView the created adapter
   myListView.setAdapter(mSimpleAdaptor);
}

Hope this will help you to understand.

You should not use the SAX Parser and use the Simple XML Library instead. It has the @ElementMap annotation for exactly this purpose. This turns your entire problem into one annotation and three lines of code to read the XML in. Look at my blog post on including the library in an android project and look at the Simple tutorial if you want to see how to use all of its cool features.

Edit: I just realised that I have answered this question before in one of your previous questions. I'm done trying to convince you to look into Simple XML; but please, stop posting essentially the exact same question in five different ways here; people have helped you already, give you answers and lead you in the right direction. It is now time to read more, experiment and learn.
