[jdom-interest] DTD parser

[J. Albers]

Hey all,

Is there a DTD parser in JDOM, and if so, does someone have an example of
some code how a DTD is written to a JTree? Right now i'm using another class
for the DTD and it writes to the console, but i have very much trouble
getting it right in a JTree. I'll show u some of the code.


Thanks, Joachim.

protected static void printElementTree(DTD dtd, DTDElement element,
  String pad, Stack stack)
 {
        if (stack.contains(element.name))
        {
   System.out.println(pad+" -- "+element.name);
   //Main.elements2.add(new DefaultMutableTreeNode(element.name));
            return;
        }

        stack.push(element.name);

  if (!(element.content instanceof DTDContainer))
  {
   System.out.println(pad+" -- "+element.name);
  }
  else
  {
   DTDItem[] items = ((DTDContainer) element.content).getItems();

   Vector elems = new Vector();

   for (int i=0; i < items.length; i++)
   {
                if (items[i] instanceof DTDContainer)
                {
                    expandContainer((DTDContainer) items[i], elems, dtd);
                    continue;
                }
                else if (!(items[i] instanceof DTDName))
                {
                    continue;
                }

    DTDElement currElem = (DTDElement) dtd.elements.get(
     ((DTDName) items[i]).value);
    //Main.elements2.add(new DefaultMutableTreeNode(currElem.name));

    if (currElem == null) continue;

    elems.addElement(currElem);
   }

   if (elems.size() == 0)
   {
    System.out.println(pad);
//                stack.pop();
    return;
   }

   String pipePad = makePipePad(pad);
   //DefaultMutableTreeNode node = new DefaultMutableTreeNode(null);
   for (int i=0; i < elems.size(); i++)//moet elementen omdraaien.(nog
loepje maken)
   {
    DTDElement currElem = (DTDElement) elems.elementAt(i);

    if (i == 0)
    {//alleen alsals eerste(of enige)
     printElementTree(dtd, currElem, pad+" -- "+currElem.name, stack);
    }
    else if (i < elems.size()-1)
    {//als niet de laatste en niet de eerste
     printElementTree(dtd, currElem, pipePad+" |- "+currElem.name, stack);
    }
    else
    {//alleen de laatste
     printElementTree(dtd, currElem, pipePad+" +- "+currElem.name, stack);
    }
    //Main.elements2.add(node);
   }

  }
//        stack.pop();
