A case of jumping in with both feet! Apologies for implying that this
may have been a bug (I've done you an injustice James :-) - of course,
the 'elementIterator()' method is only intended to return elements ;-)
...however, I do need an operation that returns all elements plus any
text content for my particular application, so I'll use my solution.
Cheers,
Iain

SUBJECT: [dom4j-user] bug?
Hi,
I experienced what I think is a bug in the framework. When a
DefaultText is added to a new DefaultElement and then the
elementIterator() method is called, the returned Iterator is empty. Is
this behaviour expected or is it a bug? I have written some sample code
(below) to illustrate what I mean.
QName name = new QName("Element");
DefaultElement element = new DefaultElement(name);
DefaultText text = new DefaultText("Text");
element.add(text);
// This does not return the text...
Iterator it = element.elementIterator();
while(it.hasNext())
{
System.out.println("Child: " + it.next());
}
// ...this does
System.out.println(element.getText());
I can make the Iterator return the DefaultText by modifying the
elementIterator() method in the DefaultElement class. The type-checking
of the content variable is modified to check for 'Node' instead of
'Element'. I can simply use my modified code, but I would prefer to
have an 'official' build if this is a bug!
TIA,
Iain
