[jdom-interest] Element.getChildren(java.lang.String name)?

[Gary Bentley]

Try:

Element root = doc.getRootElement ("complexType");

List items = root.getChildren ("sequence");

if (items.size () == 0)
{

    System.out.println ("No sequence items");
    return;

}

ListIterator listit = items.listIterator ();

while (listit.hasNext ())
{

    Element el = (Element) listit.next ();

}

I see what you mean. However I'm trying to use an Iterator to "iterate"
through this.

Element root = doc.getRootElement() // complexType

java.util.Iterator iter = root.getChildren("sequence").iterator();
while (iter.hasNext())
{
	org.jdom.Element elem = (org.jdom.Element) iter.next();
	System.out.println(elem.getName());
}

This should be the same thing I thought.
