Create xml tree

Question

Hi, I am trying do small application for showing tree structure of XML documents.
And how can I create tree of xml document with bad structure?
I can do it, when the xml file is correct. But I cannot make xml tree when the document has wrong tags:
<rt>
     <aaa>
          text
          <bbb>
          <ccc />
          <ddd>text</aaa></ddd>
</rt>I know, it is bad xml document, but is there any way how to create tree? Samething like this:
rt
     +aaa : ERROR
     -bbb : ERROR
     -ccc
     +ddd
          -aaa : ERRORI use these metods and at first build xml:
     public void buildXML(String fileName) {
          try {
               SAXBuilder builder = new SAXBuilder();
               builder.setValidation(false);
               doc = builder.build(fileName);
          } catch (JDOMException e) {
               e.printStackTrace();
          } catch (IOException e) {
               e.printStackTrace();
          root = doc.getRootElement();
     }then I get xml tree:
     private DefaultMutableTreeNode tNode = new DefaultMutableTreeNode();
     public DefaultMutableTreeNode getTreeNode() {
          tNode.removeAllChildren();
          makeTree(root, tNode);
          return tNode;
     private void makeTree(Element el, DefaultMutableTreeNode tn) {
          DefaultMutableTreeNode tn_2 = new DefaultMutableTreeNode(el.getName());
          tn.add(tn_2);
          Attribute attr;
          for (int i = 0; i < el.getChildren().size(); i++) {
               Element el2 = (Element)el.getChildren().get(i);
               if (el2 instanceof Element) {
                    makeTree((Element)el2, tn_2);
     }can anybody help me, please?

The question makes no sense. You display something that isn't tree-structured data and ask if there is any way to display it in a tree structure. Well, no, there isn't.
And also, no XML parser will complete parsing of a malformed XML document. It's against the rules.
