Re: Dynamically Processing Nodes

Cool...

Thanx for the tip.

This makes sense.
Will spend some time with this over the next couple of days.

Thanx Diez,

Good to know :)

I still think that its basically the way I said before - what you have
with 
you rows is a tree. To create a flat list of rows (or RowCollections)
you'll 
have to traverse this tree with an vistor like this:

class RowVisitor {
  List _rowList = new LinkedList();

  public void visit(List rows) {
    for(Iterator it = rows.iterator(); it.hasNext();) {
       visit((Row)it.next());
    }
  }
 
  public void visit(Row row) {
    _rowList.add(row);
    for(Iterator it = row.getRowCollection().iterator(); it.hasNext();)
{
      visit((Row)it.next());
    }
  }
}


This should end up with a list of rows in the correct order. Now for
the 
rendering - the rowspan is (1 + row.getRowCollection().size()). Maybe
you 
have to make the visitor tag the rows with additional information like
depth 
to make the rendering of the colspan easier. The colspan is (3 -
depth).

Does this give you an idea?
