[jdom-interest] RE: Need help

[Syloke Soong]

I wish to suggest that the whole chunk of code be broken into individual
methods, so that the name of each method reflects what we wish to
accomplish. To make it easier to follow.

I am suggesting the following incomplete code, where I give only the
traverseXXX methods but not the processXXX methods. By doing this, we
don't have to use XPath at all because you are merely processing
immediate children.


[code]
public final static Element traverseTreatmentplans(Element rootElem)
{
  List children = rootElem.getChildren();
  Element Treatmentplan = processTreatmentplan(rootElem);
  for (int i=0; i<children.size(); i++)
    Treatmentplan.addContent(
      traversePlansGroup((Element)children.get(i))
    );
}

public final static Element traversePlansGroup(Element
plansGroupElement)
{
  List children = plansGroupElement.getChildren();
  Element PlansGroup = processPlansGroup(plansGroupElement);
  for (int i=0; i<children.size(); i++)
    PlansGroup.addContent(
      traversePlan((Element)children.get(i))
    );
}

public final static Element traversePlan(Element planElement)
{
  processPlan(planElement);
  processGoal(planElement.getChild());
}

public final static Element processXXX(Element planElement)
{
//.... do your cloning here.
//... return clonedElement
}

[/code]


Once the code is debugged, then compact all the traverse methods into
one recursive method:


[code]
public final static Element traverse(Element e, int whomDoYouCall)
{
  List children = e.getChildren();
  Element clone = null;
  switch
  {
    case 0:
      clone = processTreatmentplans(e);
    case 1:
      clone = processPlansGroup(e);
    case 2:
      clone = processPlan(e);
    case 3:
      clone = processGoal(e.getChild());
    default:
      return null;
  }
  
  if (whomDoYouCall<3)
    for (int i=0; i<children.size(); i++)
      clone.add(
        traverse((Element)children.get(i), whomDoYouCall++)
      );
  
  return clone;
}


public static void main[]
{
// ...
  traverse ((Element)rootElem, 0);
} 

[/code]
