There is no way in JDOM to get a flat view of the XML tree. You'll have to 
walk the tree (using Element.getChild or getChildren + Iterator) to get to the 
elements you are interested in.
Or... use XPath (see below)

The easiest way to directly access nodes anywhere in the XML tree is to use 
XPath expressions and an XPath engine that supports JDOM (such as Jaxen 
(www.jaxen.org) or use the latest JDOM from CVS that integrates Jaxen).
The expression "//description" selects all the <description> elements in the 
document.

With JDOM's latest:
    import org.jdom.xpath.XPath;

    XPath desc = XPath.newInstance("//description");
    for (Iterator i=desc.selectNodes(doc).iterator(); i.hasNext(); )
    {
       Element e = (Element)i.next();
       System.out.println(e.getText());
    }
