Hope this helps I would suggest start by downloading the functx .xq file from xqueryfunctions.com/xq/download.html to an area in your workspace. Then include this in your project using :
code :
import module namespace functx = "functx" at "functx-1.0-doc-2007-01.xq"

I wish this help you Not an answer to your question, but a few comments regarding your code:
You have 4 memory leaks when you add the 4 new instances of Product to your array. The array retains the objects you add to it, so you should autorelease the Product instances when you add them. In dealloc you should say self.title = nil instead of [self.title release]. Although your version works, it leaves you with instance variables that contain references to deallocated objects (= dangling pointers). Because this happens in dealloc and the Product object is going away soon, it won't hurt you now, but you will get bitten at some point in the future if you keep to this style. You don't need to declare the instance variables, and you don't need to synthesize the properties. The compiler does all this for you. In initWithProduct you must not check things like if (title!= nil) - just say self.title = inTitle straightaway. After all, initWithProduct is an initializer just like init, so title cannot contain anything at this point.

wish of those help i have a custom list view(like blow) and i have an array list that fill with hashmap , I have made new Adapter Code using ViewHolder Method Try this one:
code :
  public class messages_Adapter extends ArrayAdapter<HashMap<String, String>>
{
    ArrayList<HashMap<String, String>> MessageAdapter=new ArrayList<HashMap<String,String>>();
    Context context;
    int layoutResourceId;

    public messages_Adapter(Context context,int layoutResourceId,ArrayList<HashMap<String, String>> MessageAdapter)
    {
        super(context, layoutResourceId, MessageAdapter);
        this.MessageAdapter=MessageAdapter;
        this.context=context;
        this.layoutResourceId=layoutResourceId;

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parrent)
    {
        HashMap<String, String>hashmap_Current;
        View view=convertView;
    final ViewHolder holder;

        if (view==null)
        {
            LayoutInflater layoutInflater=(LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            view=layoutInflater.inflate(layoutResourceId, parrent, false);
        holder=new ViewHolder();
        holder.lbl_MessageID=(TextView)view.findViewById(id.xActMessages_LblMessageID);
        holder.lbl_MessageContent=(TextView)view.findViewById(id.xActMessages_LblMessageText);        
        holder.lbl_TimeAdd=(TextView)view.findViewById(id.xActMessages_LblTimeAdd);
        holder.lbl_DateAdd=(TextView)view.findViewById(id.xActMessages_LblDateAdd);
        view.setTag(holder);
    }else{

        holder=(ViewHolder)view.getTag();
    }

        hashmap_Current=new HashMap<String, String>();
        hashmap_Current=MessageAdapter.get(position);

        Log.e("Zdit", hashmap_Current.toString());


        holder.lbl_MessageID.setText(hashmap_Current.get("id").toString());       
        holder.lbl_MessageContent.setText(hashmap_Current.get("message"));       
        holder.lbl_TimeAdd.setText(hashmap_Current.get("time_add"));       
        holder.lbl_DateAdd.setText(hashmap_Current.get("date_add"));


        return view;
    }

    static class ViewHolder {

        TextView lbl_MessageID, lbl_MessageContent,lbl_TimeAdd,lbl_DateAdd;

    }
}
Fill a custom integer array with ints

Fill a custom integer array with ints

it helps some times Firstly, what you are really doing is recreating vector, not array, because your construction parameter is not required to be known at compile time. With that in mind, you need to be using dynamic memory unless you change your approach to passing the size as a template parameter and storing an actual array instead of pointer (this is exactly how std::array works).
And so, using dynamic memory, the constructor becomes:
code :
intArray::intArray( size_t n )
    : head( new int[ n ] )
    , currentSize( n )
{
    std::fill( head, head + n, 0 );
}
for( size_t i = 0; i < n; i++ )
{
    head[i] = 0;
}

Any of those help XQuery is a functional language. As such, variables cannot be reassigned once they have been declared.
The following code should do the trick:
code :
array {
  for $child in $collection
  where contains(data($child/node1), "Hey")
  return $child/node2
}
