[jdom-interest] JDOM and recursive documents

[James Cook]

This works, but as I dont know how you hold the values, I have made a vector
of String arrays.

    public void run() {
        Vector v = new Vector();
        v.add(new String[] {"a", "b"});
        v.add(new String[] {"c", "d"});
        v.add(new String[] {"e", "f"});
        v.add(new String[] {"g", "h"});
        Element root = createXML(v);
        Document doc = new Document(root);
        XMLOutputter serializer = new XMLOutputter();
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        serializer.setIndent(true);
        serializer.setNewlines(true);
        try {
            serializer.output(doc, out);
            out.flush();
            out.close();
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }
        String tmp = new String(out.toByteArray());
        System.out.println(tmp);
    }

    private Element createXML(Vector data) {
        Element element = null;

        if (data.size() > 0) {
            String[] nameValuePair = (String[]) data.get(0);
            element = new Element("NameValuePair").setAttribute("name",
nameValuePair[0]);
            element.addContent(new
Element("Value").addContent(nameValuePair[1]));
            data.remove(0);
            Element child = createXML(data);
            if (child != null) {
                element.addContent(child);
            }
        }

        return element;
    }

output:

<?xml version="1.0" encoding="UTF-8"?>
<NameValuePair name="a">
  <Value>b</Value>
  <NameValuePair name="c">
    <Value>d</Value>
    <NameValuePair name="e">
      <Value>f</Value>
      <NameValuePair name="g">
        <Value>h</Value>
      </NameValuePair>
    </NameValuePair>
  </NameValuePair>
</NameValuePair>

Folks,
 
    After making several attempts and looking up all
the archives, I seek your input in solving this
problem I encountered.
 
    How do I use JDOM to write/create an XML document
that has a structure similar to the one shown here:
 
    <NameValuePair name="a">
        <Value>b</Value>
        <NameValuePair name="c">
            <Value>d</Value>
            <NameValuePair name="e">
                <Value>f</Value>
                <!-- Further nesting possible -->
            </NameValuePair>
        </NameValuePair>
    </NameValuePair>
 
    Any help, including code samples are highly
appreciated.
 
regards,
Vijay
